"What a lemon – do not buy"

1.0 rating
Very Unsatisfied

Since purchase in August, 2009, this gas boiler has been trouble. At least 3-4 times a year, we get an ignition error – "ignit error". The reset button does not help. The plumber has been here at least a dozen times, replacing the wick, cleaning the ignition, and various other maneuvers. This is a lemon, do not buy it.

"Believe the negative reviews–huge fail"

Peerless- pf-210 High efficiency unit ($9000) was installed 5 months ago to replace 50+ year old gas furnace heating house with hot water. Suddenly and without warning house became cold. Reading code said "Fan Speed Error" System locked. Technician came out and thinks it needs new combustion blower. This is the weekend, middle of winter. Have to wait until Monday to order parts. Space heaters keeping house livable. Reading reviews now and they all sound so familiar. I think a class action suit is on the horizon for Peerless.

"Persistent flame failure A02"

1.0 rating
Very Unsatisfied

This boiler was installed by a large, well-advertised professional heating outfit in 2009. It worked as expected the first year. Year 2, there was no heat on the first cold day. The outdoor sensor circuit no longer worked. The sensor itself and the wiring were okay. Fast forward to 2014, where the PF-110 has A02 flame failures. The same large, well-advertised heating outfit replaced both the ignitor and flame sensor at $800. It was $400 just for the two parts which were marked up 4x in price. They wrote down 88% efficiency on their service notes. The next morning, it still had same flame sensor A02 lockout. I need to hit the reset button on a daily basis to keep the turd running. I had to fire the large, well-advertised professional heating outfit due to a lack of funding.

"Worse than crap"

1.0 rating
Very Unsatisfied

When the boiler was first installed, I spent 11 weeks without heat or hot water. I learned to boil water on the sink to wash my hair and go to neighbors for a shower every couple of days. Eventually, I had to drain the water lines and abandon the house through Christmas. A factory specialist eventually came and then they replaced the boiler. During heating season I expect to have to go into the basement and reset it because of lockout errors on a weekly basis. You get used to it; it feels cold in the house and with no hot water, and then then you pray that the reset works instead of having to go a week without heat or hot water. After that, about once a year this suffers total failure, usually in winter of course. Often it's the $600 blower fan, although the main circuit board has failed twice as well. On the second replacement of the main board, I got one where they have it try resetting itself hundreds of times because of the constant failure of the sensors. This helped some. At this point the system has been installed 6 years and I'm getting quotes to replace it for $15,000. If someone is thinking class action lawsuit, count me in. I have documentation of all this.

Garbage! I had to purchase this because of Hurricane Sandy for $3300, and less than two years later I had to replace the blower and circuit board for almost $700. Now, two weeks later, it's not working again! Garbage!

Other Purefire Reviews

Although several contractors posting on online discussion forums praise the Peerless Purefire series’ sleek design features, including the interface screen designed for easy programming, few homeowners across the web are as pleased with the unit. Sites such as or host forums with a variety of customer complaints and troubleshooting issues. Instances of the boiler leaking, the unit failing to fire, faulty control boards and the unit not heating water are among the problems reported.

The review site notes that the Purefire’s condensate management system is a unique feature and the durable stainless steel construction is a benefit to the unit, but mentions that the warranty on the unit is not very comprehensive.
