Overview of the HE
The Hawken Energy HE is an outdoor wood furnace with a water capacity ranging from 150 to 368 gallons and a heating capacity ranging from 144,000 to 358,000 maximum BTU. The unit's water jacket completely encircles the structural steel firebox. It has a large wood loading door and an easy access back door, and the furnace is mounted on steel legs which eliminates the need for a concrete pad and helps keep rodents out. An automatic forced draft fan provides faster heat, and a stainless steel chimney cap keeps water out of the furnace while lowering heat loss. The powder coat metal exterior features enhanced green paint with black trim. The 2015 starting price of the HE furnace is $6,495 plus shipping and installation. Financing is available.

Our Hawken HE 2100 is 6 years old and developed a leak. Called the company and they told us that water samples weren't sent in so no warranty coverage. They will sell us a new one "discounted", plus sales tax and delivery charges, but that's all. They do not uphold their warranty and they do not last. Hate the thought of buying a new one every six years. They say their wood stoves are the best but haven't proven it to me.

"Hawken works great"
We bought our Hawken 2100 four years ago and love it. Two years ago when the "stars aligned" we had one of the coldest winters in years and the high prices of the "propane shortage", remember that? It was 80 degrees in our house and 45 degrees in our 30x50 pole barn. We also have the unlimited hot domestic water. I have not had any problems with my Hawken. I load it twice a day and burn soft wood when it's above 30 degrees. I do the maintenance double their recommendations, empty ashes 2 times a month etc. I would definitely buy another one. Did anyone ever ask their local tree services what they do with the trees they cut? Many tree services sell firewood but many will give it to you if you ask. One full time tree service gives me everything he cuts. Two part time tree services give me their wood too. One of them lives within 10 miles of me and brings it to my house in a dump truck. I have 2 additional tree services for backups. My oldest brother and I have 5 years of firewood each (he has a Heatmor). Robert

"Awful customer service, don't buy"
Bought my unit in 2008. The unit developed a pin hole leak in the inside corner of the door, exactly as another post here has stated. Instead of calling Hawken, I had a certified welder fix it. Four hours later, I had a 6" piece of angle steel welded to the box because he couldn't get anything to stick to it. His exact words, "junk steel". This year I went out on Thanksgiving morning and found the firebox filled with water. Sent everything to Customer (dis)Service and it took 5 weeks to get an answer. Just as the others have noted here, my warranty was void due to water samples and poor ash removal. Seems to be a theme here. I missed my second year sample and the dealer that I bought it from said " don't worry, just add a 1/4 gallon of treatment every year and you'll be fine. (Which I have done) Along with my non-answer from Hawken, they sent me their current warranty information for their boiler. There are 4 additional steps listed that aren't listed in the owners manual that I received with my purchase. Three of the things that they tell you not to do, I have been doing for 8 years. I extended my chimney with single wall pipe and lowered the temperature on the aqua-stat, and I fill it with wood. Unbelievable that they would tell you not to fill the unit. All of these things, (if you can believe them) will lead to premature failure and void the warranty. They offered to sell me a new unit at cost, I pay the shipping, a $0.00 cost resolution to them. They say that most people pick them up because of the shipping cost, which leads me to believe these failures are very common. I have emailed them twice more without receiving an answer. I would also join a class action suit if there is one. Anyone that purchased prior to Hawken re-writing their owners manual is at risk.

We bought a 409 stainless unit from Hawken because we have sulfur in the water which a water softener does not remove. The seams were welded with common rod instead of stainless steel rod and they cracked the first time the heat was removed. Hawken said the manufacturer was no longer standing behind the warranty but they did replace it with one they started making themselves. I told them about the sulfur and they said the 1/4 in mild steel would stand up to it with no problems. In December 2014, the bottom rusted out. It turns out their water treatment does nothing to stop the sulfur from eating the steel. When they found out the water treatment did nothing for sulfur, they told me that because the water had sulfur in it the warranty was void. In Ohio almost all ground water has sulfur in it that is not removed at the water treatment plants. In addition the unit had no damper so you always got smoke and fire in the face when you filled it. It also used more wood than the original unit. I regret not having the original unit repaired locally by a good welder cutting it open and redoing all the welds. I would not buy anything from these people again.

I am very pleased with my wood burner. It has been problem free for 4 years and seems to use less wood than my neighbors brand x burners. My only complaint is that the fan kick out breaker is located on the rear of the wood burner and a panel has to be removed to get to it and it's a little bit of a reach to locate it. All in all the Hawken wood burner does its job and if I was in the market for another one Hawken would be the first one I would look into.

"Awesome wood furnace!"
I love this stove. I like not having a wood stove in my house anymore, or climbing on the roof in the winter to clean the chimney. I also like not having the wood mess in my house anymore. I love the stove because it is well built and insulated. I actually get snow to accumulate on the roof of the stove. It eventually melts away, but only because the chimney camp shoots the smoke down towards the roof.

"Keeps me warm"
I buy all my firewood and still save thousands every year. The furnace runs flawlessly and has worked very well. My house is warm, my wife is happy, I'm happy. Thanks Hawken.

I really like the unit itself, I think it's a great investment. I do not like the fact that I have had to replace the high limit control sensor several times since I have had it.

"Outdoor wood stove"
My second outdoor wood stove. Wood consumption is about the same as my last outdoor stove (not a Hawken). The Hawken works fine, I do get some condensation around the loading chute but all in all a good unit. I have had it in operation since 2012 with no component issues.

Hawken he-1100 installed December 2011. Has been a great furnace absolutely no major problems. Saved a lot of money compared to using our oil boiler. Definitely would recommend to anyone that is interested in installing an outdoor wood burner.

"Unit has been great"
I bought this unit and installed it myself in 2008. I was lucky, from what I understand earlier units were not as well made and I had a dealer who was very helpful. I have only had one repair issue that occurred two years after purchase. The power cable that runs from the main unit to the loading door broke one morning when it was about -10°. I hadn't talked to my dealer yet when Hawken sent me a replacement cable with the explanation that many had been breaking and they were sending every customer a replacement. Other than that, 8 years with no problems.

"Did not stand behind the warranty"
I bought our Hawken outdoor wood burner 6 years ago for the price of $8000.00. Every year I would send in my water test to see if I needed to add their chemicals to the water. I did not have to add anything until the 6th year, they sent me a paper saying I needed to add them. So I called my distributor that we bought from and bought and added them. That winter the 1/4" metal on the front and the back side of the lip of the entrance to the burner created a leak. After contacting the distributor and him calling Hawken, we had no answer for almost 3 months. After calling time after time, they finally told us that they would not stand behind the warranty because I didn't send in a sample after adding chemicals. And several other lousy excuses (didn't empty the ashes, which I did 3x a month). They even told me to weld it and then they would reinstate the warranty...how bogus is that. They do not stand behind their warranty.

I purchased my he-1100 from a local dealer, Aeon. They guaranteed this model would heat my 3000 square foot home and hot water heater. I have burned over 100 cords of wood winter after winter, my house never reaches above 72 degrees. December 2014, I found the firebox full of water. I called Aeon, who could not come up to look at it and did not attempt to contact the company as he promised to. After a month of fuel oil I called Hawkins. I was emailed a form to fill out, along with a detailed request of how I cleaned the furnace and how often, and they wanted pictures, which I did & returned. Waited another month, waiting on a call back from the owner. Finally, 3 months into no outdoor boiler, I received an email stating find a local welder and good luck trying to weld it, as the 20-year warranty is voided due to lack of water samples. The leak is coming from the back, up on the top and is not visible. I have ask for assistance and a layout of this furnace and have not received it. I am very interested in hearing from anyone that has a similar problem, has gone the legal avenue or knows of a class action lawsuit. Hawkins does not stand up to their warranty & their service department is of no help as they just explain they have not had that problem before. The ground thaws in the winter where the lines run from the furnace to the house. These furnaces are not made for the below zero temperatures in Northern New York. Help if anyone can, I would like to hear from you!

"Doesn't uphold warranty"
I have had my stove for less than 5 years. I developed a leak in the system. I was told to empty the stove and take pictures, which I did. Right away Rich in technical support started right off telling me my warranty was void do to water samples. He didn't show all of them, then he told me I didn't maintain my ash good enough, all before he knew where it was leaking from. He then had me refill the stove and find the leak. It's in the top of the stove, in the water jacket. Ash didn't cause that. They then sent out the repair guy and he said it wasn't caused by our error, it failed prematurely. Now they want me to pay for the repairs and say the stove only has a couple years life left in it, what happened to the 20-year guarantee? They look for every reason they can to not warranty their product. I have had cheap stoves last longer then 5 years. I will probably seek a lawyer because at this point I have a ten thousand dollar boat anchor. I will not recommend to anyone and I only live 15 minutes from the company.

I live in central Wisconsin and paid over $3500 in propane last year. I studied outdoor wood furnaces before I decided to purchase a Hawken. I am glad I did. I love my unit. I work 12-hour shifts and I have an hour drive time to and from work. The burn time of my furnace is around 16 to 17 hours when it's near zero and around 24 hours when it's near 30. I burn only oak and do not split it if I can lift it. I think that is key. People have a tendency to split their wood too small and it just burns to fast. It's been in the 50's lately and the burn time has been like 50 hours or better. I am heating a 2000 square foot log home and it has no problem keeping the house 73 degrees all winter. It is the middle of March and I have not even burned 4 cord yet. I read people burn a lot of wood and just want to tell them, quit splitting your wood. I have a 30 by 50 pole building. Next year I am also going to heat my 30 by 50 pole building with my unit and I believe the unit will heat both with no problem. Love my Hawken.

I purchased an he-2100 in the spring of 2009. It keeps a house of 1900 square feet at 68 degrees. As of now, I'm running a 1500 watt electric heater to supplement, due to minus 6 degrees temperatures outside. I run the water pump 365 days. Replaced it last summer due to the hours on it. I will keep it as a spare. Nice unit.

After having an indoor forced air wood burning furnace in use for the last four years, and after having to bring the wood into the house and have all the fine particulate ash and smell in the house, I plunged into the outdoor wood furnace/boiler arena. I looked at several major brands, and after months of poking and talking to others and reviewing websites and forums I decided on a Hawken Energy he-2100. This unit is easy to operate and we have all the heat we need and then some for our 2800 square foot home. Plus, we use a plate heat exchanger to heat our domestic hot water, which has yet to run out even with two teenagers, laundry and dishes all happening consecutively. I bought a unit bigger than my house needs so I can eventually heat a pole barn when that gets built. I also like that, for me, the unit is made in my home state so should warranty work ever be needed during the 20-year warranty period, the manufacturer is close by.

Purchased my he-2100 last fall. No problems, except for some of the caulking peeling up. Heated my large home nicely and didn't use a ton of wood. It was the coldest winter in eighty years, and we only burned 12 ricks of wood and kept my house 78 degrees all winter and had more hot water than could ever be used. I will begin burning in the next few days. The only people around here that don't like a good outdoor wood burner are the electric companies!

I am very pleased with my Hawken 2100 series. I put it in my new house as I was building it, it heat's my two water heaters, I have radiant floor heat in my masters bedroom and bathroom, and it supplies my two furnaces with hot water for water to air heat changers. I burn green whole wood some split, but not much. I installed the entire system myself it's not hard anyone can do it. My home is 7000 square feet and I heat the entire home with this wood stove, at a temp through the winter months of 75 degrees. It does all this with ease. I did a lot of research before I purchased a stove, and talked to a lot of people. I'm very pleased on my decision in buying Hawken!! When you read about people having trouble with their stoves, most of the time they have not taken care of it and didn't read the manufactures booklet on how to operate the stove. Every stove is different on operating procedures. If you want advice from me make sure you have a nice platform for your stove to set on. It makes a big difference! I am going to build a cover over mine to protect the stove and to keep wood closer this summer. Thanks again Hawken Energy!!!!

"I love my Hawken Energy HE-2100"
I purchased my he-2100 back in 2010 and am just starting on my third winter with it. The unit has been great. There have been no problems and no complaints. I'm saving thousands of dollars. My old farm house has a fuel oil furnace. I haven't filled the tanks since I purchased the 2100. In fact, I haven't burned a single drop of fuel oil. I purchase my wood and it's still cheaper than the fuel oil, about half the cost by my estimates. At the time I'm writing this your site places Hawken as #6 on your list. I don't understand why. The unit ranked higher had fewer reviews. I smell a rat. Anyway, Hawken is #1. My neighbors have other brands and every one of them has had troubles. In fact, two of them don't even use their boiler any more because of all the problems they've had.

"I am owner of this heating system and I am very satisfied."
By the way , the brand of my heating system won the Energy Industry Comparison Report's "Top Choice" award in 2007. I 've owned wood furnace since 2007 year I have never repair it, it works quite good. . I am burning red pine and sometimes red pine and oak. The longest burn I have had is about 10 hours. My home is about 2400 sq. Ft. Now that I have the wood boiler going I also am heating the basement space, which adds another 1300 sq. Ft., With half of it crawlspace. I'm just getting used to the thing and playing around with fan speed and different loads. I got 12 hours out of a load last night and it was below zero here. It took me a week or so to have enough faith in it to start stocking it with the unsplit rounds that the manual says to use. I do now and next spring there will be a lot less splitting. When I was getting ready for this winter I wasn't sure what to expect so I have about have my wood split up that didn't have to be. Scott, are you using unsplit rounds? I found it made a difference in burn times, ash buildup and wood consumption. I'd also get some chunks of hardwood in the mix if you can, especially for the overnight burns. I've also turned the fan speed down. I'm working in my office at home now with a window looking at the boiler so I've been able to watch a lot of cycles. I had the fans cranked thinking the sooner I get into gasification mode the better. But it seems to kick in just as quick at a lower speed and I hope I'm not blowing as much heat out the stack. I am very happy with mine. Wood usage has been high but I was just happy to be getting heat out of it and wasn't worried about it at first.

"I LOVE My Hawken"
We've had the Hawken for about six months now and it has taken us comfortably through a tough winter. We have many carpenter and contractor friends from whom we gather their scrap wood to burn. We also have been burning "weed" trees from our acreage that we had cut down and chopped-up over the years and left the wood to season. So basically we're heating our cabin for free. There's really nothing we don't like about it. It is so much more clean than burning wood in our woodstove and it more efficiently heats the entire cabin rather than just the great room where our wood stove it. We're seriously considering removing the wood stove, which would give us more living space. Our Hawken is even cute and, being green in color, blends in nicely on our property behind our cabin. So far it's never needed repair. We'd absolutely buy it again and have told all our friends about it. They're envious that they can't have one (most live in the city), although a few of our suburban- dwelling friends have looked into buying one (but, so far, their nasty homeowner associations don't allow them).
