"Cheap and unreliable"
I've had two generations of Laars equipment. I bought the second because it meant I didn't have to pay for a lot of associated re-plumbing. I could just drop in the replacement unit. What a mistake. The small amount of money I saved up front meant I had to spend another decade beholden to this company's unreliable equipment. It is very hard to find people who know their gear and won't gouge you (I'm in the Boston area). Spent time directly with Laars on the phone and they were completely unhelpful.

"Lockout"
We replaced the ignition/flame sensor 6 months ago due to the unit locking out a few times per week. We thought the issue was fixed but for the last few days its locking out 6 to 8 times per day. Not sure what to do next.

"A piece of #@!!"
I installed this unit 8 years ago at the recommendation of Dahl Heating and Plumbing, a big company here in the West. They also recommended the installer. I had problems with it right away (leaking from the high end Myson radiators, ruined my plaster walls) but the serious issues started 2 years ago. The pump was replaced then and several other issues were handled ($750), and I just had to replace the ignitor, display panel and zone valve actuator. The plumber is here now for all that and it will be well over $1000. I have a 1400 square foot house and this unit has a lot of BTU's, yet one bedroom never gets over 65 degrees. Do not buy one of these. Every plumber who has come has said "Oh, we all hate these, they are really badly made." Not just that, but the warranty is useless; it looks great until you read the fine print. Supposedly mine is still under full warranty (10 years) but guess what - it only covers the heat exchanger and storage tank, and none of these expensive parts that have crapped out. Live and learn.

"Owning this is only slightly better than freezing"
Every year, the heat simply stops working. Sometimes in the summer it won't stop running. Sometimes in the winter it just won't stay on. It's hard to say what will go wrong, but something will. Always. Every time someone "Laars certified" is happy to show up for $200, say they really aren't too familiar with the unit because no one around here has one, diagnose the broken part for another $200, and then buy and replace the part for an additional $400 - $600. If you are looking to buy one of these, I also suggest getting into the HVAC repair game. That way, you can afford all the maintenance by gouging the pocketbooks of other, less savvy, Laars customers.

"Homeowner's nightmare boiler"
I just became a homeowner. I have a Ph.D. in medical physics and a Masters Degree in math. I have two Laars Edurance combo boilers in my house and they just break down every few months, especially the sensor. Three of my neighbors have the same models, and each neighbor has 2 boilers in their house. They also complain that they have to fix them every year. They are the nightmare of our neighbors in winter. Including mine, there are a total of 8 laars Boilers. In terms of statistics, there is enough technical date to collect and I can scientifically prove that Laars are the least reliable boilers. I'm not sure how this company can stay in business; maybe contractors get a lot of rebates from Laars.

"Take charge of the maintenance"
I was becoming dissatisfied with this furnace until I took charge of the maintenance and understanding how it works. It has not changed the fact that I have to replace parts every year -the ignitor every year and a half - but I can manage the cost of maintenance, to the point of making it a reasonable decision to keep the boiler for as long as I can get parts at a reasonable cost. I got ripped off at least 3 times by repair people in the last seven years that I have owned the furnace. I have been maintaining the system myself for two years and I estimate I have saved about $2000.00 in repair bills.

Review:
"Definitely not reliable"
We purchased and had this unit installed in January 2000. It is fired with natural gas. The only reason we replaced it was to switch from oil to gas. The old oil boiler was 35 years old and worked without the need for any repairs, other than a once-a-year maintenance check. This Endurance EBP unit has been problematic since day 1. You name it, almost every single component has failed on the unit during the last 14 years, starting with the first year of ownership. We abandoned the idea of using it as an on-demand domestic hot water in the first year, and had a storage water tank piped into the system. Then, venting through the liner in the chimney caused too much condensation, so it was later vented horizontally with a stainless steel vent out the side of the house. Igniters (yes multiple), water flow control, control board, and unexplained lockouts have been repeated issues. About 3 years ago, the heat exchanger failed and we had to install an indirect hot water tank as a separate zone. Just about every year there has been another problem with this boiler. Never purchase any Laars product.

"Nightmare boilers"
I bought the house one year ago in Brooklyn. There are two Laars boilers in my house - one is for the 1st and 2nd floor, the other one in for the 3rd floor. The first one broke 3 times in one year and the second one broke once in a year. I talked to my neighbors and figured out that 3 of our neighbors have the same boilers. So each house has 2 boilers and there are 4 houses, including my house; therefore, there are 8 boilers. The reason why the same boilers are in the 4 houses is because they were built by the same company. I talked to my neighbors about the boilers and they said they just keep breaking every year. Laars is a piece of shit. The computer board, the sensor, the ignitor and more are not working. Avoid Laars or itís your nightmare.

"Worst boiler on the market"
Boiler is 10 years old and I have had to replace the ignitor every year and half. I have had constant lock out problems and repairs that are now up to almost 2k. I have to look at the display every morning when I go to work and when I return to see if its locked out. What a poorly designed product.

"Satisfaction"
I live near Burlington VT and have installed over 30 of these in many applications including primary secondary loop systems, Heatmaker retro fits, new homes (etc). If the plumber installs it correctly and an experienced technician starts it they can be as trouble free as any other and better reliability than most of the beer-can boilers claiming 95% efficiency.

"Has tech issues"
I have two of these boilers installed in a San Francisco 2-Flat building. Both started having random lockout issues from the beginning, initially about once or twice a year, now about once or twice a week. A few months ago, both started having ignition issues, so I replaced the igniters on both. That helped for a while, but recently one unit starting having severe ignition issues. Having two, I started swapping components between the two units to determine the source of the problem. Swapped gas valves, problem stayed with the boiler. Swapped boiler control circuit boards, problem stayed with the boiler. I need to do more research to determine what else could cause the gas vale to not open or go shut while operating. I noticed that Z1 zener diode on both circuit boards has been fried (smells bad, obvious soot around/above the component), so I called Laars tech support to learn what other component in the boiler would cause that failure and got the answer "we don't troubleshoot individual components, just replace the ($421) circuit board. It probably failed due to condensate." Lotsa help they were. A few more problems... nobody seems to have these things out west, so all parts need to come from online dealers in New England. And they require hookup to the potable water system via a backflo preventer... annual cost to certify those valves.. $400. I am looking for a replacement boiler that can operate on glycol. It won't be a Laars.

"Worst boiler experience I've ever had"
I bought a lovely house in a rural area and inherited a Lars Endurance boiler that is fueled by propane. I have had nothing but problems and expensive repairs from day one. Each year I have spent $600-800 in repairs of one kind or another until today when I am again out of hot water because the mother board needs to be replaced among other things...So I am replacing the boiler entirely. My sentiments echo the other reviewer who wants to smash it and send it back to the manufacturer. It's sad.

Year 7 - needed new valve Year 8 - needed the same new valve as year 7 Year 10 - needed new ignitor, new boiler, new pump (installing one seemed to break the other) Got ripped off by service man who said he needed two people to do the year 10 job. We had to pay his apprentice (new guy who didn't know anything) $40 per hour to stand there and learn from Mike Patterson in North Bay.

"The worse piece of equiment that I ever had installed inside my home"
I see that I am not the only one who have the same problem with that unit. It's time for me to go ahead and tell my stories. I built my home in 2001 and I have a Laars furnace installed in my new home and the plumber told me that unit is the best unit he has. But, to my surprise the guy lied to me. The first winter that guy came into my home four times to replace different pieces inside that furnace. Since that time he came at least three time a year to replace all kinds of parts. From 2001 to 2014 he came to my home at least 35 times. The last time he came on 01/28/2014. He came four times this year already and I have another schedule appointment with him and another person from Laars. I recommend to everybody: never use that company. I am preparing to sue the plumber and that company for damage and all the trouble they've given me.

"A Waste Of Money"
I had to replace the old Trianco Heatmaker with the Laars Endurance EDP 110. I thought it was an improvement over my old Heatmaker. I was wrong, it was even worse. I had it for less than 3 years and it was already broken. I had an F4 error and won't start up. The service tech has replaced the pump and the supply sensor. It still doesn't work. The computerized system sucks for diagnosing problem. At least the old Heatmaker would always start up. I will never buy this brand again.

"Piece of S$&?"
I have a cottage in upstate New York. We installed the Laars boiler at the recommendation of our contractor. He had the same unit in his shop. We are on our 3 circuit board. Seems every time we have visitors, the unit fails. The service techs can seem to locate problems when they occur. The unit is totally unreliable and expensive to keep running. If I lived there year round, I would have replaced it for my health and well-being. Run, don't walk from this brand if you can. If you're like me reading about these product after it is installed, your contractor owes you an apology..

"Thinking about replacing already."
We bought this brand new condo 7 years ago. The unit has been a nightmare. My wife's brother has plumbing/heating business. Everytime he has had to work on this furnace, he has called laars and the first thing they tell him is to replace the most expensive part or they don't give him any help troubleshooting. This week we had to put in a new circulation pump and then only after the 2nd call to laars did tell there was a problem with the water flow switch. It is running ok for now, but we are considering putting a new furnace the next time something goes wrong. We are tired of throwing good money away.

"We installed a lot of them. Now they are ALL failing."
I own an hvac company in Ontario Canada. a few years back ,we were convinced by our supplier to install Laars boilers. What a huge mistake. Almost every one has been a nightmare. The Endurance is one of the worst units I've ever had the misfortune to work on. The corrosive condensate collects in the bottom of the heat exchanger. This is where the ignitor/flame rod assembly and venter motor are located. The condensate, being acidic, makes quick work of them. I have ended up fixing them, over and over, at my own cost, out of guilt for installing them. Laars is completely useless! They will never admit that there was a huge design flaw in this unit, as well as almost all of their equipment. Laars commercial boilers are, believe it or not, even WORSE! The Mighty Therm 2? I'll be lucky if these don't bankrupt me! They self distruct. They EAT ignitors, and the burners disintegrate every year or so. Laars excuse for this was that the boiler combustion was not set up properly. BS!! They were meticulously adjusted on install and even double checked by another company! The burners melt themselves, the burner compartment and case. It's a major job to tear them down and rebuild them every year or so. I WILL NEVER PURCHASE LAARS AGAIN.

""THE GOOD OLD DAYS""
July 16 (daddy's birthday) When my mother purchased a laars edp boiler 15 yrs ago, we thought we were installing a Cadillac to replace the pieced together collection of used parts my plumber daddy installed over the years. He had disabled all of the safety interlocks on the boiler and made strange noises in the middle of the night. I used to have nightmares about our house burning down because of that boiler in the basement. Well comparing the old piece of junk my daddy installed over the years with the nice new laars boiler, I think we could easily say the cost has driven up astronomically. We likely could have operated the old system for 50 more years for the same money mom has spent on the initial installation and repair costs for the several thousand dollar replacement components over these 15 yrs. The bad part about it is I didnít read all of these 15 terrible consumer reports before telling the repair man to bring us a replacement control unit module. Sadly it is probably just a $2 capacitor that needs fixing, but mom will have to shell out $1100 to replace the whole control module to able her to again wash her face with hot water. The good old days really were great! Daddy's old furnace was noisy and looked like junk, but it ran better and cheaper than mom's new replacement Cadillac.

"TOTAL WASTE OF MONEY"
When we built our retirement home in 2003-2004... we thought we were putting in a high-end system that would be efficient, cost effective and give us years of good service. We were wrong! The Laars Endurance ebp 110 has cost us literally thousands in repairs and parts. We had our first issue 27 months after installation. The flame igniter has been replaced 6 times now, the actuator valve & switch replaced, inducer ventor motor burner column replaced. The warranty on parts is generally 1 year and they need to be replaced after 1 year no doubt about it! We have had no success with Laars Canada except to say that the techs you speak to on the phone are very nice but can offer no guarantee of hope for resolving any of the on-going issues with this system. No one wants to admit there is a design flaw! We are now keeping this system going until May (using parts from other Laars systems that have been scrapped by their owners)and will put in a furnace, hot water tank and some other system where we can utilize the hydronics in our basement. To say we are frustrated, angry and disappointed is understating our situation.

"Never Again!"
I have never been so disappointed in a piece of equipment as I am with this Laars EBP110 boiler. I began having problems with it after only 4 years. It is continually Locking Out and my serviceman can not find out why. He has even called the company itself, to no avail. I have had to replace the circuit board twice and the ignitor 4 times. Once after only 6 months. The cost of all the service calls would have been astronomical if it weren't for the wonderful serviceman who doesn't charge me for every call out. I would have been in the poor house years ago if that were the case. Some weeks he is here at least 3 times. I am now looking at having it replaced, but have not decided on a suitable replacement yet. I'm dong my homework this time.

"Waste of your hard earned money"
After the first year we had to put in over a $1000 then it has cost us money every year...finally the installer told us he has replaced every one of the units he has put in. We are looking at 10 to 12 thousand dollars to replace now. ARE You kidding me!!! We hired a professional and this is what you get... so much for warranty, that means absolutely nothing. Its hard to get parts. Why is that my problem? You had no problem taking my money when we built our new house. We have no hot water now because the system has failed again and we don't have another 12 thousand to spend. We live in Alberta Canada where it goes down to 30 below zero....SO Now what do we do?

"Troublesome Experience"
After only 2 months of operation, the inducer fan failed. After 20 months, the dhw flow switch failed, and had to be replaced with an improved version (paddle switch) that necessitated additional plumbing mods. The anti-condensing valve was the next to go and after 3 years the unit started making loud roaring sounds upon start-up in high-fire mode. Laars said it is caused by clogged coil assembly, which is costly to replace or clean due to accessibility issues and component cost. No one wants to service Laars units.

I purchased this unit after the big "sales" job on how great this unit was. The unit was compact relative to what it would provide; i.e. domestic hot water, in floor heating and heating for the air handler. the electronic main board failed a few years. Now, the combustion chamber coil is blown, the water flow sensor has failed and the DHW heat exchanger is showing early signs of failure. Given all the initial positives that were indicated to me upon purchasing the unit, it is so very disappointing to have mulitple heating contractors talk about how poor the Laars has been in their opinion.
