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 #@!!"

1.0 rating
Very Unsatisfied

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"

1.0 rating
Very Unsatisfied

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"

1.0 rating
Very Unsatisfied

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"

3.0 rating

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.

Other Endurance Reviews reveals an interesting discussion about a Laars Endurance boiler. The homeowner is interested in installing a combination model to supply heating and enough hot water for a whirlpool bath. An installer mentions that Laars is a reliable brand, but that many other brands are reliable also.

One consumer mentions a problem with a Laars Endurance boiler and asks for help on The boiler will not turn on; an HVAC expert responds saying it may be a problem with the outdoor sensor. The consumer decides to call a technician.

Customers can write in to and some companies have actual representatives that will respond. A Laars customer service representative took part in a discussion about a faulty flow switch on an Endurance boiler. Laars has redesigned the flow switch several times in an effort to prevent leaking. The customer was able to locate an acceptable replacement for an affordable price.
