"Failed Twice in Seven Years"

Very Unsatisfied

I went high efficiency, and got burned. Expensive to buy, Expensive to replace parts. Don't buy this piece of junk.

"Ouch, worst boiler and company ever."

1.0 rating
Very Unsatisfied

I was sold 3 of these boilers by * * * ********** in Eagle, Colorado. They pawned many of these boilers off on us home owners in the Vail Valley, Colorado. They had the condensation tube pinched on one and the inlet outlet reversed on the outlet of the boiler. On might say * * * ********** suck as bad as the Peerless boiler company does. Both firms either can't install a boiler correctly or build a boiler. Ouch, ouch, ouch with owning this boiler. Every year you have to buy new parts and like the one guy said, "You are afraid to go on vacation in the winter for your pipes will freeze and Kaboom, now you have a flooded house". This is so crazy to own this thing. How do we do a class action suit with them?

At the moment we are sitting in our home with 4 portable heaters as our boiler unit has failed us again. My husband did a great deal of research on this system when we built our house 11 years ago. We believed we made the right choice despite the initial expense. Guess we were wrong, very wrong, in believing the rep we bought it from. Why is this company still in business after not standing behind this product for so many home owners? I would support a class action lawsuit! Extremely disheartened! Wisconsin home owner.

"Flame sensor"

1.0 rating
Very Unsatisfied

Worst money I ever spent.The Peerless unit shuts down after the boiler fires 3 time and the flame sensor does not sense the flame. After cleaning the sensor with an Emory cloth the unit will fire, but expect to come home or be up with the circulator pumps running because it doesn't last more than a day at best. The company does not stand behind their product, I will be replacing the unit.

"Repair expenses outweigh any efficiency savings"

1.0 rating
Very Unsatisfied

Thinking I would save the environment and fuel costs, I had a very reputable, diligent and intelligent installer put in a Peerless Pinnacle boiler to run on LP. The unit has had failures both under warranty and after warranty. It has had fan motors fail, a complete boiler breakdown, and is now needing possibly yet another blower motor or something following a pressure switch failure code. This type of boiler is not going to be at the hoped for 90+% efficiency level heating water to the necessary temperature for a hot water radiator system anyway so the efficiency factor is negated from the get go. It might have such efficiency for an in-floor radiant heat system. This furnace was a waste of my money, the installer's time, and the environment's resources. I will have to go back to a simple, usable, reliable stainless steel boiler. Until then I have to pile some firewood on my wood fireplace fire and pile on the quilts to stay warm until the unit gets repaired once more or replaced for good. At this point, my best choice might be to cut my losses and replace it to avoid future breakdowns and repairs.
