Overview of the Classic
The Central Boiler Classic is a wood furnace available in four models, with a tank capacity ranging from 140 gallons to 764 gallons. It features a ripple top design for increased heat transfer area and a vent cap designed to eliminate evaporation. The unit's large, insulated cast iron door is designed for easy loading and maximum efficiency, with a powder coating for increased paint durability. A water-filled HeatLock baffle will not warp or burn out, and sprayed-on urethane foam insulation forms an airtight seal around the water jacket. Due to the EPA's New Source Performance Standards, new Classic models will only be available until the end of 2015. Base models of the Classic start at $5,490, though prices can vary depending on shipping and options.

"Glad I sold it!"
After reading the reviews of other people's stove rusting out I am glad I sold mine this summer. It was a model 5036 & just gobbled wood. I called several time to Central Boiler & really didn't get any satisfaction & same with the dealer. This was a major expense to purchase this thing. I have a cast iron stove in my living room that I used before the Central Boiler & using it today. Last weekend when we had -15 degrees I went through about 5 armloads of wood, not as much as the boiler would hold. I would have to fill that boiler 4 times on a day like that & was concerned it would be out in the morning.I do have to wonder now if I buried my piping deep enough as it would melt the snow where it was laying, but I used what the factory recommended. The stuff you could lay on the ground if you didn't get it buried in time. I couldn't go any deeper than 1 ft with this stuff with where I was burying it. I ran into someone else that had an older version of my unit, (which was made in 2007). He had the same problem, & no help from Central Boiler. He ended up selling his & getting a different brand the next size bigger & went through way less wood & didn't have to fill it as often. I am a heating contractor by trade, & replaced a furnace this fall for a customer that has an outdoor boiler. Different brand, similar size house but does not use the wood that I did. His boiler even had less water capacity than mine did. I just don't get it. Very unhappy with the Central Boiler I had. Wouldn't recommend them to anyone!

"Contaminated steel in firebox, rots in 4 years."
I cannot say enough negative things about Central Boiler - I bought a CL 6048 in 2009 and got the 25-year warranty for it. I use it for heating my shop and house, and it runs all winter long in Connecticut. It worked fine for the first 4 years, and then began to pit on the right inside face of the firebox. The other sides and baffles were fine, but over the last 3 years it has gotten so bad that the pitting has eaten right through the steel into the water jacket! I called Central Boiler and tried to get them to honor the warranty, and they proceeded to tell me that I needed to be using the water treatments (which I have used the entire life of the furnace) and it was my fault for not maintaining it! I do everything they mention in their owner's manual, and when I told them that the steel was contaminated (per a metallurgist's inspection) they told me there was no coverage in the warranty for that, only for cracks and welds, and there was nothing they could do for me. I will never purchase another Central Boiler again, and advise everyone else to do the same, as they do not stand behind their products. A furnace like this is a major investment, and should last more than a few years.

"There is no warranty"
They advertise a 25 year warranty but midway in to my 2nd winter of use it sprang a leak on the back under the chimney. Dealer came out and pulled off the foam insulation on the back and it had rusted through from the outside in. Since I used the proper cb chemical and kept the ph correct, the interior of the steel was perfect. Pinholes had leaked under the insulation and corroded it from the outside. You could punch through the steel wall, it was so thin. My dealer figured they had gotten some bad Chinese steel. He called it in and here is what they offered to do. Next time they had a truck in West Virginia they would pick up the boiler and take it back to the factory and repair it with me paying for the labor and return shipping and installation. Plus I had built a sturdy lean-to cover over it that would have to be dismantled. And I wouldn't have heat for the rest of the winter. I told the dealer that was no warranty and he agreed. He hired a local welder to repair the back then I painted it with hi temp engine paint and sprayed it with foam myself. It has worked fine since. They do not stand behind their products!

Installed it myself, tied it into the same system as my gas boiler so the gas turns on when the wood burns down. It has worked perfectly for ten years with zero issues. I live in southern Alberta Canada and it gets very cold in the winter. This boiler works great. I'd agree with the comments from those who had someone install their boiler. Seems most experts are full of it these days. I recommend, if possible, doing it yourself.

"Quickly rusted, now junk"
I bought a 5030 Classic in 2007 and in 2008 the door handle came loose and water boiled out. They did honor the guarantee since others had the same problem, I just had to pay the shipping. Now last fall the thing started leaking from the outside. I took off the insulation only to find lots of outside rust and holes on the bottom, none on the side. After calling my dealer and Central Boiler they wanted pictures, then more pictures. Now they want water tests. I told them there is no water, it all leaked out and that I did all the testing and used rust inhibitor yearly. Getting the runaround and thinking I will weld it myself. Stay away from Central Boiler.

"Best Boiler on the Market!"
My husband and I built a house in 2007, we had a Portage and Main outdoor boiler installed for our main source of heat. We had nothing but issues with it constantly going out and not working properly. The second winter we had enough with it and replaced it with a CL 5036. This was by far the best decision we had made. The CL 5036 is so easy to maintain and run and cut our wood consumption by almost half! I highly recommend Central Boiler products to everyone!

"Central Boiler 6048"
I finally purchased a Central Boiler 6048 in late 2015 after thinking about buying one for quite a while. My dealer was very helpful and talked me through doing the installation by myself. It's been running every day now for about 4 months without any problems. The gas company sent out an inspector to double-check our meter because we hadn't burned any gas during the winter. He saw the Central Boiler and just shrugged and left.

"This stove stinks"
Yup, this stove stinks! Bought new in 2014, paid $16,000.00! A few months into this the stove circuit board went out ! Approximately 6 months later the solenoid went! And now, approximately 8 months later, pumps went out! Installer gives me the runaround if he even answers the phone! Called the company, they will not take credit for the junk stove. Refers me to installer (person we bought it from) who by the way is not very friendly once he has my money! So do I recommend it? Absolutely not! In fact, after reading all these reviews, I now realize that everyone who is having problems are having same problem as me! Hmmmm...I talked to a friend of mine and I'm seriously thinking about contacting a lawyer about a class action law suit against this company!

I have had my Central Boiler since 2008. It does a fantastic job of heating two houses and my shop, total square footage is over 10,000 square feet, and when this one wears out I will be upgrading to one of the new models that burn even less wood. So in other words I am a very satisfied customer of Central Boiler.

"Love this boiler"
This is our 14th heating season using our Classic Boiler. We love it! We live in a huge old farm house and this heats us nicely. I have heated our house with mostly dead trees and broken limbs from our farm. It burns big ugly pieces with ease. I only split 'nice' wood for my small shop wood stove. It is built like a battle tank, and obviously has lasted well. We had a cracked door after the first couple of years. The company replaced it totally free and sent us a new improved design on the new one. Can't say enough for them. This boiler has saved us thousands and thousands of dollars worth of propane. We figure it paid for itself easily within the first three years. Plus, I love the exercise of cutting wood and living a self-sustainable life style. I still keep my propane tanks full, and the propane boiler is plumbed into the same radiator system so when I get lazy or when the earth is so muddy I can't get to the woods, we burn gas. Otherwise, this boiler is our winter's heat. I fire it about once per day making the 'right' sized fire for the weather. It will heat our house two or three days if loaded and fired hard. That's not how I like to burn it though. Seems very efficient and only has visible smoke when loaded with fresh wood. Once it is burning hot, our neighbors don't think we're using the boiler because they can't see anything coming out of the chimney. Dry wood is the key.

For heating the water 1-10 I would rate it 15! For heating our home 1- 10 I would rate it 3! I can't get the inside temperature over 66 degrees no matter how often or how much I stoke the fire! When I open the door it is just charred wood, no fire! I use a leaf blower to get the flames back! We have 50+ acres so we have abundant access to fire wood. The dealer said it would heat our home, greenhouse (being built) and our barn (still to be built). There is no way this wood furnace is going to heat all three. It can't even heat our home adequately! We wasted a lot of money for the purchase and install! I would never recommend buying this! UPDATE: 1/7/16 I must rewrite my review of my CL6048! I had written a pretty negative review about the heating capabilities/problems I was having. The last few days had turned cold, lows into the upper teens and I wasn't able to get the house above 66 degrees! I called the dealer /installer (Kelly Jones), which I should have sooner, and told him what was going on. He said the fan isn't kicking on and said the A/C circuit breaker has to be on. I told him we had turned it off when we installed it. I told me to recheck it! Sure enough, it was on! Turns out our son had been using power tools a few weeks ago and tripped a breaker. He went downstairs and turned everything back on and of course never said anything! I turned it back off and the furnace kicked in. I am now able to set the thermostat at any setting, and my wife is warm. (Yeah - I'm out of the dog house!) I opened the door to the wood furnace this morning, and every piece of wood was completely burned to ash! That is what I thought it should have been, not charred hunks of wood staring at me! So I sincerely apologize for writing a negative review when obviously "I" had the problem! I am now anxious to finish the greenhouse and start heating it, then onto the barn! I would also like to thank Kelly Jones for being so patient and helpful! Any time, every time I've had a question, he has been there every time! I should have called him sooner!

" Scammed and defrauded by ******* *******, Central Boiler dealer"
Asked to come to Indiana to start and complete sale because I didn't want to do it online. ***** never came out to our home to access what we had. From the start when he did show up he argued about what information I provided him with starting with the size of our home. Did the sale and charged no tax because we were out of state, the sale took place at his store in Indiana. Purchased on 8th of September. Waited for 6 weeks and finally went there to find out our unit was gone. Came to our home with the unit unloaded on October 17. Never registered our unit. Had problems with his install including paying for thermopex only to have it stripped back over 5' and laying underground only 12". I asked about freezing and was told it won't happen. Started unit and called ***** back with our unit overflowing. ***** came back once to switch lines cause they had them crossed. After that unit overflowed because ***** hooked into our existing furnace, pressurized, and went to a non-pressurized furnace; that caused it to overflow on a continual basis. I then called ***** for over 4 weeks with no response from him. Contacted a licensed heating contractor. Gentleman from there said the dealer should be put out of business. Called the factory and haven't heard back from them on their dealer's install and his fraudulent practices. We were scammed and don't want anyone else to go through what we are now going through.

"Bad materials, junk boilers, shitty warranty"
I bought this unit in 2005. I loved it until it sprung a leak. I took the best care of it. When I talked to dealer he was very nice. The manufacturer was something different. Tried to tell me I burned garbage. Never, not even one time, did I burn anything but good hard wood. The dealer told me .250 thick steel, manufacturer told me it was 7 gauge which is .187. I am a welder fabricator, when we cut into it it's more like 10 gauge .125 not even close. Read your warranty - after 2 years it is 50% gone, at 9 years where mine failed they cover 25% of parts. They wanted 5100 dollars to replace the firebox. The 25 year warranty is to make you think it's going to last. Building junk, they lie.

Just like other people, after 10 seasons my firebox is leaking. I went to start my boiler for the season and discovered the firebox was full of water. I used my fingers to find the source of the leak and punctured a hole about the size of a quarter in the steel.

"Greatest Purchase my Family has made on Heating Costs"
I purchased our boiler in September of 2014. It is the single greatest purchase I have made for my home. It has reduced our heating costs in half, and has allowed us to keep our home warmer than ever before. Radiant heat is cleaner, produces less dust and allergens and is quiet! Our boiler requires minimal upkeep and is extremely efficient. I have zero dislikes abut our boiler. I can heat the house as hot as I want it and not worry about high heating bills. I purchased a Central Boiler due to the reputation they have. I have friends using units well over 10 years old. I have had to make zero repairs to my unit, and I know it's a quality unit. I would highly recommend this brand of stove to all my friends, and I do on a regular basis. I am beyond words with how happy we are with our boiler. We will be using this for many, many years to come!

"Good luck here"
I purchased this boiler in 2004, a Classic 4036. I'll be on my 12th heating season this year. I change the water every 3 years and have used only treated filtered water softener water in it with Central Boiler's water treatment. I have always used Ashtrol in it and burn seasoned wood only. I do have the inducer fan option. I have had to replace the door gasket once. I run it from late October to mid-April, and I clean it completely at seasons end. It does our water also. I cover the chimney with a cap during the off-season and have a spark arrestor cap on it during the heating season which also keeps rain/snow water out. 11 years and no heating bill so I'm probably ahead, on rural remc here .22 per kilowatt hour effective rate.

"Top of the line Central Boiler"
I've had this Central Boiler for about 5 years now and it's been amazing. We live in northern California and don't use the furnace as much as someone in Ohio, but it still gets quite cold here (in the teens) and has done the job well. Very fuel efficient and it has reduced my electricity costs by a lot. It heats my hot water, the whole 6 bedroom house, and our garage (which we use as a recreation room) so it works out nicely. Since this was my first home and boiler, I used the financing option and they offered very reasonable and affordable financing which was a plus. I find that I can burn any quality wood, whether dry or damp and it still has seemed to work fine for me. Lastly, I typically fill the boiler once every day or two, sometimes even every 3 days depending on the time of year we are using it, so it has been very low maintenance for us. When looking to buy boilers initially this was a concern for me and this furnace has been great to us.

"Best on the market"
I have had a Central Boiler Classic 6048 for 14 years and have nothing but great things to say about it. I heat my house and garage, I fill it once a day and it couldn't be easier. I also heat my hot water. I have a BoilerMate plumbed in and never run out of hot water, no matter how much we use. I would advise anyone looking for an outside wood boiler that Central Boiler is the only way to go.

This is the worst I have had, I can say this because I had one in my previous home but I had a Heatmor Furnace. My Heatmor was amazing! This furnace has been nothing but trouble. Constant problems. Air in the line, it won't work. My last straw was this morning when I had to take a cold shower because it won't heat the water like it is supposed to. My husband insisted on this one because it was "cheaper". Well, you get what you pay for. Heatmor cut my heating bill down to nothing and saved on my electric bill. All I have seen the Central Boiler do is get your hopes up. My heat bill is the same and I watch my husband feed the beast with no results. Please save your money. The ratings on this furnace are terrible. One person praising the furnace sounds like a sales ad. Anyone who says this furnace is a good one got lucky. Luck is not what I want when I want to heat my home and save money.

Had it ten years, already have had multiple leaks in the firebox. The walls are paper thin metal. If you are going to purchase one of these, do yourself a favor and weld steel plates all around the firebox because it will leak. You do not want to go out to the boiler and find your wood soaking wet in the middle of winter like I did yesterday morning. It is sickening how expensive these are and how the firebox can't last long at all. I am not the only one who has had this problem. I paid $8341.38 for a leaky firebox, wonderful!

I have read so many reviews on Central Boiler where people are very dissatisfied with Central Boiler systems. First, your dealer makes the difference. When I was looking for a boiler, I looked at several different choices of boilers. I talked to the dealers of various factory makers. Then, I chose Central Boiler. The first dealer I talked to was in it for all of the money he could get out of me. He stated to me the warranty he did not do, that was up to Central Boiler, they would send someone if the warranty had to be done. I told the dealer I would get back to him about the purchase. I went home and called Central Boiler Company. The person that I talk to stated to me the warranty was authorized through the dealer only. Then I got on the internet looking for other dealers in my area. I found three others, checking with the business of the chamber and reviews from other that dealt with the dealers. Out of 4 dealers, only one came back with excellent report. I called the dealer and told him what my square footage was. He quoted a price which included delivery & installation. The next day I traveled to the dealer, sat down at his desk and talked about the boiler, warranty, price, and his responsibility as the dealer. He put the same price quoted on the phone, including warranty, installation and his responsibility as the dealer, all in writing. I bought the CL 4030 the next day. They delivered, installed the system, and were gone in 2 1/2 hours. Most of the blame against Central Boiler is the dealers fault. You have a mind of your own, do the questions, check the dealers, go to the chamber, check the internet, called Central Boiler factory and ask them about this dealer. They told me I found the best dealer they have, he only sells and installs Central Boiler. Go talk to owners of Central Boiler like we did, just by driving around. See a Central Boiler in action, stop and knock on the door, ask the owner all the questions in the world, then decide on whether you want Central Boiler. I am on my second heating season with Central Boiler. I heat a 1120 square foot home, including a hot water tank and a 10-foot x 20-foot wood working shop. The CL 4030 is the smallest system. The very first fire put in the boiler on the first heating season, the fire went out. The water temperature was 160, the damper did not open. I called the dealer and he had me take the damper cover off the door. One of the two cotter pins had came out and was in the bottom of the cover; it had not been bent over at the factory. As soon as I put the pin back in and turned on the power, the damper opened up. My dealer called me that afternoon and asked if everything was all right. He also called me the next day make sure every thing was working right. This is my second heating season with no problems; my dealer has called me 2 times this season checking on the system. "If you can not depend on your dealer, then do not buy Central Boiler". All dealers are not the same; they are in it for the money and once they have your money they are done with you and do not care. My little boiler is amazing it only burns 8 split pieces of wood 16 inches long every twenty four (24) hours at 3 degrees below zero. Thank you Central Boiler! What a wonderful product and dealer.

"The Satisfaction that Accompanies the Use of Great Boilers by Great Companies, Central Boiler Company, Great for Corn and Coal"
I have had my boiler from Central Boiler, model Classic CL 4030, for about a year now. We, that being my family and myself use it for the winter cabin we have in the Great Smokey Mountains. I like the fact that there is limited evaporation as compared to other boilers in its same category. Its size is also a big plus. As well, the fact that we can sit it outside and forget about it. What really helped me and my family is the fact that they offer low financing. This was one of the main reasons that we bought from this company as opposed to other companies in the same industry. I would absolutely buy this brand, make and model again. The amount of heat it provides our winter home is astronomical. Not once in the year that we have owned our boiler have we had to make any repairs on it.

I've had the unit for almost 10 years with no problems,no rust at all. I've done practically nothing, just kept it burning and cleaned out at the end of the season. I treated the water initially and tested it from time to time but only had to add a little water twice. The unit is not very efficient and smokes a lot but I burn poor quality wood, not always dry. I'm in the tree business so it works great for me.

Before buying anything from Central Boiler, watch what you sign. After the deal is done, the dealer will present form 4949 created 5-2008 that states the boiler has a pro-rated warranty on the firebox/water jacket. Our furnace is on the sixth year and the whole back of the unit is rotten and leaking. I was told by Central Boiler that they would only pay 75 percent of material cost only. Ask to see the warranty and read it carefully before purchasing. They use deceptive practices in selling these units. This unit will never make 25 years as the warranty says and they know it. Only buy a Central Boiler if you are willing to have a welder come in and repair it every couple of years.

I have had my Classic for 3 heating seasons. It works great, I only load it once a day during normal winter temperatures of teens and twenties. Now there are sub-zero temperatures and I have to load it twice a day, but that is to be expected. My home is 2000 square feet and I'm also heating the domestic hot water with a family of 4. My dealer has always been there for me. Last year we had strong winds and it blew my carport into my burner, and ripped the chimney off and damaged it. My dealer fixed me up late in the evening with a new chimney section.

"Worst customer service I have ever had"
I'm not sure what to think about my Classic boiler as I have no idea how to operate it. I bought a home with a boiler already installed but no manual, and when I contacted the company for a manual they refused to sell one to me and referred me to a a dealer. I have no local dealers, so I called one several towns away and since the didn't sell it to me, they were in no hurry to assist me. I would never recommend this product to another person.

The warranty sucks - read the fine print! Had it 5 years, used it 6 months out of the year, and one side had pinholes after 4 years of burning. I get 2 months in to burning it this year, and the same thing happened to the other side. I called the company, and they said they would start a file on it. I could also send it back at my cost, and they would fix it and I would be without a burner for 6 to 8 months. Whatever. Don't buy one!

Purchased new and have only used for 3 seasons, exactly as specified. We followed all the cleaning instructions, and yet have a large hole in the back of the unit that allowed the box to get too hot and damaged the air tube. Central Boiler has been extremely unresponsive, unconcerned and if we do speak with them, they are generally rude. The supposed warranty is a joke. We have had several master welders look at our unit and they can't believe the poor quality of materials and workmanship, not to mention the overall poor design. They sent us a repair kit for our hole, but we are responsible for everything else, including paying for shipping! The dealer has also been no help at all, and he, too, acknowledges that this is how Central Boiler does business. We are so dissatisfied and frustrated. We don't know if we can even use the unit.

I have a Classic 5648, I believe it was made in 2000. I bought it used in 2006. I live in a temperate climate near Portland, Oregon. I burn 8 months out of the year to heat a 2500 square foot house, garage and hot water exchanger, and use 5-6 cords of dry wood a year. I typically fill my boiler once every 3 days. My neighbor, with a similar sized house and using a competitors brand, was filling his 3 times a day. Granted, he has a slightly smaller unit. I believe mine is a very efficient boiler. Besides regular maintenance, all I've had to replace is the door gasket and the draft door solenoid, both low-cost items. I'm surprised to see several bad reviews; most seem to be owners of an E-series. I'm happy with the Classic, I figure I've saved about 10K in heat bills over 8 years and only paid $2800 for the boiler.

"Great luck with this unit"
I purchased a Central Boiler Classic 7260 new in November 2005 and have had nothing but great luck with this unit. If you are not familiar with the 7260, it is the largest unit that Central Boiler makes besides the pallet burner. The 7260 has a water jacket of 764 gallons; I believe the pallet burner has a water jacket of around 550 gallons. I heat 6 buildings with this unit, totaling around 14000 square feet. Yes, that is 14000! I replaced a previous boiler in 2005, which I had for 14 years, after it finally burned out. I hooked this unit up myself. The only problems I have had with this unit the blower are the motor burned out, and the bearings on the camlock for the door broke. We start heating in late October. April of last winter was a true testament of the unit. We burned close to 40 cords of birch, which is pretty much all we can get here in Northeastern Minnesota. That is the most we have ever burned in a winter. I'm not complaining one bit about it after you look at what propane did last winter. For a short period of time last year, propane was over $6 per gallon. It only takes a little simple math to figure out the savings. Yes, it burns a lot of wood. If you installed a wood boiler with the expectation of filling it once a day, I think that is a far cry from reality. I fill mine a minimum of 2, if not 4 or 5, times when we see -30 degree weather or colder. Everyone's heating system is different, and the building(s) they are heating are different. I hope that when people are reading or writing these reviews, they take into consideration other factors, like how efficient the building(s) they are heating are, and what type of wood, wet or dry. This unit does not seem to care what type of wood goes in there, it all turns to dust. I use a water/glycol mix, and I clean and inspect the firebox throughout the heating season and off season. So at the end of the day, I am very happy with this unit and I would buy this brand again.

"Junk. Worst thing I every purchased. Wood hog/ poor design"
Problems from the start door activator plunger problems overheating fire goes out freezing in 0 temps to light back up pump problems leaks, what a waste of money, very disappointed. 10,000 dollars of trouble Don't buy please bad products. Burn a semi truck load of wood a month. and still was cold! Took 4 hours before it would heat back water to 185 degrees after running out of wood. Load 3 times a day, then at night -- fire goes out before morning. Poor design. No blower draft takes a while to get wood going again while your outside freezing in 0 temp to restart.

"Central Boiler Junk"
Had Central Boiler for seven years when it burned out. Dealers told me to contact Central Boiler, Central Boiler told me to contact dealers. Refused to stand behind their product, accused me of burning garbage in the unit. I timed going to our local dump we live 4 minutes from our dump so why would I burn garbage. Was told by vice president, must clean the boiler out and scrape with wire brush in minus 30 degree weather. That was not stated in the manual. When the rubber meets the road, the quality of steel used is very poor. Asked for mill test report 4 times, no response. I would stay as far away as possible from Central Boiler.

"Outside Wood Stove"
CL40 which has 400 gallons of water. Been heating 1200 square feet house for 19 years. Also, use to heat garage on weekends. Unit has had no real issues, though seems to use a lot of wood. Though, I cannot compare to any other stoves, as this is the only one I have had. I would like to try a draft blower to see if it would lower wood consumption. The salesman I talked to says, it would only push heat out chimney but most stoves now come with blowers. I am currently looking for another stove for different location, but am not buying Central Boiler again.

We live in the temperate climate of South Central Alaska, (+10 to -20 degrees F.) Yellow Spruce is our main source of wood. Heating oil is $5.50+ per gallon. We installed the cl-4030 in 2008 and have not had a single issue with the unit. Burning from September to April using about 10 cord, it heats our 3800 sq.ft. home and domestic water rather easily and cuts 60% from our fuel bill. The reviews about leaks concern me. I keep a proper ph balance & make sure the rust inhibitor is where it is suppose to be, also the unit has Glycol in it, time will tell. Great product!

"No More Propane"
I have been very happy with my Central Boiler 5036. I am on my 3rd season and haven't had any problems. I heat my house (1600 square feet) and my garage and my hot water. I get anywhere from 12 to 18 hours of burn time and that's just the front of the firebox full. Spend a little more money and get a Central Boiler. You will be glad you did!

"You Need to Read This if You Have Central Boiler"
I purchase a Central Boiler in '05. I loved the boiler, I get wood for free and heat my house and garage with it and hot water. I built a pavilion around it to keep the wood dry so less smoke nice dry wood. Had four pipes on the chimney. Blower on the door for a more efficient burn time. Well, two days before I was shutting the unit down, we had a fire that burned the pavilion down melted the siding on my garage. Melted windows, melted tractor, did a lot of damage to property. Come to find out the 90 on the back of the unit. The inner 8" wall was gone making it single wall pipe, also the first pipe off of the 90 4' section inner wall dropped 6" down into the 90 slowing down the draft. Which in turn started the fire. I have insurance on it. The insurance company had the veo from Central Boiler and the chimney company came to my house to look at this problem. The insurance had an engineer there, also to show the problem with the pipe and the 90 out the back. Central Boiler didn't want to hear it. They told us that the double wall 10" pipe is not a 0 clearance pipe. I also had the plumber that installed the unit there. The chimney people told us that the pipe is only good for 5 years. It was a Lennox pipe 10" with 8" stainless steel pipe. I was told the outer wall is stainless and the inner wall is not stainless. Really? How many people know this. I just wanted people to know that in New England, I have a lot of people that have these unit with roofs over them to keep the wood dry. I had 2' on center framing where the chimney went through the roof with a chimney cap to keep it away from the wood by 6" and the chimney people said, the chimney is not a 0 clearance pipe. But could not tell me why the inner 8" wall dropped inside the pipe and why the 90 inner wall was rotted. I have had it like this for 9 years with no problem. People need to know about that 90 and the 10" stainless steel pipe problem that they are having.

"In a pickle but happy on the product"
I read through these reviews and I'm surprised to see that most, if not all of these reviews are from folks who have not had their boilers in service for very long. I have had my boiler in use for eight years and I would consider my usage on it extreme. cl 4036, and it heat my mid sized home and a triple car garage with ease. I did the entire install of the system myself, and have had zero problems until 2 weeks ago. I was having to refill the system which obviously indicates a leak. Found the leak site under the boiler at three different spots. all 1/4 inch circular holes. Two at the back spaced 1 foot apart almost at the weld seam, and on the left side at almost the weld seam. I drained and welded on all three spot two times now and the metal is pretty thin around those holes which is difficult to seal up welding on my back in winter. I have never added any anti corrosion to this system like cryotek, and maybe thats why the water is leaching metal. I check water ph on the unit like you would a pool monthly. Likes to be on the alkaline side if anything, but never the less, balanced. I dont add the inhibitor because of the need to shut the boiler down in winter. To do this, I hook an air hose to the system and blow out the lines. Happens once or twice during the winter for me. When I get back, I refill the syetem, bleed the air, and fire the boiler up with no problems. I still have leaks to date which led me to this site. I think Im going to use an epoxy pipe sealant and see if I can limp to spring. Then I'll have to tip it on its side and rebuild the bottom of it with new metal. How someone could get 25years out of a boiler with no problems doesn't seem possible. I suppose if a person were using something other than water like propylene glycol, which would cost a fortune to fill. Regardless of my situation, I am happy with the unit and our minnesota climate keeps the stove at peak usage all winter long. Sadly, it had to be done, my home furnace is heating my house. My suggestion to Central boiler would be to prespray a ceramic coating on all the panels of steel prior to fabing and welding the box together. Heated water is leaching the metal, find the fix guys!

"Does the job and does it well"
Ive owned this furnace from central boiler for a little over a year. So far what ive liked about it is that it was worth every penny I paid for it. It produced the same amount of quality heat as other ones I was looking at except I saved over 500 dollars purchasing this one instead and it was the best choice I have made in regards to these things. The only thing I did not like about the central boiler is that it was very loud at times. And even with that complaint I am still happy with the product. So far after about 1 year, I have not had to make any repairs to it, it works as well as when I first bought it. I would definitely tell my friends and family about this furnace if they ever needed one as I am somewhat satisfied by it.

"Advantages to having an outdoor wood furnace."
We use to have a small wood stove in our basement. We spent more time cutting the wood into 18 inch pieces and stacking it in the basement then we did enjoying the heat it seemed. About three years ago we got an outdoor wood furnace and it has been great. We have ours setup to heat our water as well. With our old electric water heater would constantly be running out of hot water. Now we never run out. I can even take a bath while my wife does the laundry. My wife was bragging about how much hot water we have to my sister in-law and she made her husband get one too. Its also very nice to not have to haul all of the dirty wood into the house. Not only can we keep the wood outside and our basement clean, but we can put much larger pieces into the furnace. We only have to stock the furnace up a couple times a day. Before we had to every few hours. I think If I were to do it over again, I'd get a Classic again, but I might have gone with a smaller one. The one we bought is a bit too large for a small home and shop like ours. It seems like the sister in laws works just as well but they go through less wood. I talked to the dealer and he said ours was a more than what we needed. Its ok though, we got a good deal on it.

"All Warmed Up In Northern Minnesota"
My husband and I purchased our outdoor wood furnace last September for our cabin because we were tired of paying so much each month for our heating needs. We chose the CLASSIC model CL-4030 because it seemed like it would fit our needs and it was at a price that we could afford. We have had it less then a year but used it over a full winter already and we were both pretty much happy with it. It looks nice, it was easy to have installed, and it really works. I think on the colder days it seemed like there may have been some more heat loss then we would have liked but overall it really seemed to do the trick. Winter of 2011 was pretty easy so we will see how it works this coming winter. The only thing that I did not like is that it seems really big for the small area that we are using it for. We have not had it for very long so we have never had a problem with it. I would buy this brand again as we seem to have luck with it and it is so easy to use and I would tell my friends about it if they were ever in the market for a outdoor wood furnace.

"Central Boiler Classic is the way to go"
This is a fantastic outdoor heater! It is efficient and quiet and clean. It has saved me so much money since we had it installed. I was paying over $500 a month in heating costs during the winter months. With my new heater my expenses have dropped to about a quarter of that. My home is also so much warmer than it was using traditional electric heat or my indoor wood burning fireplace. This thing is phenomenal!! The installers were there on time and they had it up and running in no time. They were very knowledgeable and helpful. Customer service is excellent. Every time I have had an issue I have called and gotten exactly the answer I needed without any fuss. We have owned our furnace for about 2 years now and I would never go back to electric heat. The only thing I will say negatively about this furnace is that it does take up some of the yard space, but that is minimal, and no more than an outdoor cooling system would take up. We have had no real problems with the unit-except user error. Customer service is excellent when I can't figure out how to do something. Seriously the best buy we have ever made! I would recommend this furnace to anyone looking to save money on heating costs.

"Review of the Central Boiler ClassicCL 4030 wood burner"
I have owned the Central Boiler Classic CL 4030 for 3 months now and have not had a single problem with it. My family is always telling me to turn down the heat this thing is so amazing. I like that it is easy to clean and keep up on also it looks great in my yard. It has a nice green finish with a 20"X20" medium size door that makes iteasy to load. This unit also can support 140 gallons of water which is an ample amount for me and the 3 other members of my fiamily. Another great feature is the size and weight the unit only weighs inly 1,350 pounds and the size is 40"X30"X26" which is great for my 3 bedroom one story home. If anyone asked if I would recomended this unit I would buy it over and over again not that I would have to because it is very reliable.

"I've had my outdoor wood furnace for a few seasons now"
I purchased my Classic CL 4030 outdoor wood furnace about a year and a half ago and the thing I love about it the most is the savings on our families' heating costs. It is one of the things that I take for granted now and hope that nothing goes wrong. Knock on wood, but I haven't had any issues with it yet. I purchased it from the local Home Depot and they delivered it for us and helped us as a family, install it. I did not do a whole bunch or research on the whole idea, the staff at the Home Depot knew a great deal about the various products and answered all of my questions. I would, and have recommended this product to many of my friends and family. I live out in the country in southern Ohio and the climate changes weekly so in case the weather drops suddenly the wood furnace can handle the job.

"Central Boiler Best Around"
I have had my Central Boiler Classic wood furnace for a year and a half and love it. After last year's winter, I knew it was time to invest in a new wood furnace, and I have been very satisfied with my choice. I have never had to repair mine but I have read reviews in which customers have had to have repairs done. Most complaints have been about the spark plug, which though important, is quite an easy fix. I have had no such issues with the spark plug. Other issues have also been reported but none of which I have also had happen. That could possibly be due to rough handling, but I have no complaints about mine thus far. I would definitely recommend and buy from Central Boiler again for my wood furnace needs.

"Central boiler outdoor wood boiler"
I've owned the Classic Model outdoor wood furnace for about 4 years now and it's still running great. This piece of equipment has required very little maintenance, aside from the cleaning which has been minimal (I was even able to do this myself). I love being able to provide my family with heat from natural, local, and renewable resources. As a bonus, chopping wood for the furnace gives me down time to think and also provides me with great exercise. The reliability of this machine was a major factor in my purchase, as I value being self-sufficient in any way possible. The upfront cost seemed like a lot at first, but we are saving a ton of money using a non-traditional method of heating our home. I am very grateful to my friend who made this recommendation to me, I would not have considered this otherwise. I would definitely recommend this product, or possibly a more expensive model for larger homes.

"Update on my problem"
I own a Central Boiler model# 6048. I'm beginning to doubt Central Boiler's famed warranty. I'm still waiting for them to honor their warranty on a faulty heat exchanger that they sold me. I've been working on getting this problem resolved with them for over a month now. Due to the lack of any response from both Central Boiler and their distributor D&R Country Designs, I plan on contacting the owner of Central Boiler to ask for his help with this issue. I'll keep you posted with any new developments.

"Will they Honor their warranty?"
I'm a Central Boiler Model 6048 owner for 2yrs. So far, so good. I have had one problem with the heat exchanger that Central Boiler sold me to heat my pool. It's leaking water. I have contacted Central Boiler and initially they refused to help me but later I got a call from the dealer (D&R Country Designs in Palmerton,PA) that I bought my Central Boiler from and they are willing to "look" at the defective heat exchanger. I guess now I get to see if their famous warranty is for real or just a sales pitch. I'll let everyone know what they decide to do about this problem. Stay tuned.

"Central Boiler 6048"
Purchased a 6048 for a little less than 10k in Oct of 2007. Replaces a oil furnace in a large old farm house. I absolutely love this unit!! Free hot water, and heat!! It's very efficient in the wood burn, load the stove and it normally lasts 3 days and on a below 0 with win -9 night it still lasts 24-36 hours. Great investment!
Other Classic Reviews
A homeowner on hearth.com was trying to choose between the Classic and a Heatmaster unit which was $2000 less. A couple of people said to get the Heatmaster because the price is so much lower, but a slight majority preferred the Classic because Central Boiler is a bigger company with more support. A homeowner on forestryforum.com deciding between the Classic and the E-Classic was told by most responders that the Classic is time-tested and that most customers have been satisfied with it.
Product registration is required for maximum warranty coverage. The warranty for the Central Boiler Classic wood furnace is comprised of the following:
- 1-year manufacturer defect & workmanship warranty
An optional 25-Year Warranty is available if a Limited Warranty Registration Form is completed and sent to Central Boiler within five (5) days of the original owner taking possession of the furnace AND provided that one thermostatic valve per set of supply and return lines is installed in the system.
