"Don't install an optional low water cutoff!"

5.0 rating
Very Satisfied

I have read all of the bad reviews here and there are two things I found common with all of them. First, they all had their boilers installed by a professional. And second, they all seem to be having the same continuous problem – ignition failure. And everyone who is having this problem says they try to reset it and it will not reset. Well, that's probably because the professionals they hired installed an optional low water cutoff switch that detects water flow inside the water piping at the boiler which acts as an interlock to protect the boiler if there is a low water condition detected. These low water cutoffs use a small paddle-style toggle switch that is pushed by the water flow inside the pipe to close the contact sending a 24 vac signal to the switch and back to the boiler controller letting the boiler know that there is water in the system. The problem with these switches is they corrode and fail easily, often causing a false alarm and shutting down the boiler because the boiler thinks there is a low water condition. So you can try to reset it all you want, it will not reset as long as the low water cut off switch is stuck open and the boiler thinks there is a low water condition. The boiler is actually doing what it is supposed to do. It's the low water cutoff switch that is causing your problems. And if you have hard water it will cause the low water cutoff switch to corrode and fail sooner and more often then if you are using a water softener. So if you do not want to take the low water cutoff switch apart to check and clean it several times during the winter each year, then I recommend not using a low water cutoff switch at all. I don't and I never had a problem. As long as you have a working pressure gauge just check it regularly and make sure you have at least 12 psi always when your boiler is running. As long as your gauge is showing low pressure then there is water in the system. It is a closed system so it would take a while for the system to go completely dry before the pressure on the gauge would go to 0. Another sign of low water would be the water pipes knocking and banging because of air in the pipes. Also, your baseboards will not be getting as warm as they should because water would stop circulating normally. So as long as you check these things regularly you should have no problems and your boiler will not shut down like it has.

"I will sell you my furnace"

1.0 rating
Very Unsatisfied

I echo the comments of the unsatisfied. Our experience with a Peerless Purefire furnace has been terrible. Many experts have come to our house to fine tune the unit. It works until it doesn'T. Peerless corporate service is horrible– perhaps the only company I know that does not publish a customer service number — and if you're clever enough to find a corporate number, they refuse to speak with homeowners. And that's what the Internet is for– to let the public know to stay away. That said, I will happily sell any of you reading this review my furnace. A Purefire PF-399. Now about 4 years old and in as good condition as it ever was. Cost me $15000 to install. New the unit is $9000. Yours for only $2000. I'm in northern NJ. Email me at [email protected] Seriously. I want to buy another brand.

"Fan blower"

1.0 rating
Very Unsatisfied

After 6 months of a good job keeping up with the winter and keeping the house warm, the fan blower gave up. After calling Peerless I learned that this specific fan blower doesn't like water and might break down on me. Well, why would they put this blower on the bottom of everything? And the kicker is they told me after 6 months of use that I'm not covered; I will have to pay. So if anyone is planning to do something against this company please let me know, thanks. P.S. – Don't buy Peerless.

"Run away!"

1.0 rating
Very Unsatisfied

This unit was professionally installed in June 2011 by our area's largest and most reputable hvac dealer. The cost was over $10,000. In the first 2-1/2 years it failed 18 (!) times. Twice, "factory reps" were here to re-install. It is professionally serviced every year. And it failed again this winter for the 20th time, three months after the last service. As others have stated, we, too, cannot leave the house for long because we never know when it will fail. This is horrible! When I complained to the HVAC company, they were upset with ME because I complained. I chose them (the highest bidder) because they promised to carry all parts all the time. Three times they did not have the necessary part. In addition, the owner admitted that he is having problems with this brand, but it's not his fault. He said I should take it up with Peerless. Really? That's how he stands behind his work? He knows that there are many similar situations throughout the USA with Peerless, but Peerless is doing nothing to help. I contacted three other HVAC companies to evaluate the boiler/installation and to get estimates to replace. Each commented on very much the same, somewhat minor installation methods. More importantly, each said that if it was something that he installed, by the third failure he would have replaced it and taken up the matter directly with the manufacturer. Does anybody know if there is a class action suit/settlement? I would join in that.

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.
