Peerless Pinnacle Boiler Reviews

We have had numerous problems and have two local HVAC repair people on speed dial. Every time we have a service call, it works for a while, but then another issue pops up. It was the most expensive part of our new construction, as we did all of the other work ourselves, but it looks like we will be replacing it soon.

"My 10 year old boiler is shot!"

1.0 rating
Very Unsatisfied

My home is 10 years old and after dumping $4,000 into repairs on this piece of garbage, I was just told my boiler is shot and needs to be replaced. The model # is P-104LPREV1 (not available above so I just picked the closest) and the rep told me they only last 10-15 years. I had this boiler serviced every year but it just keeps going out and left me without heat and hot water for more than 15 days this cold winter. I was living out of a bag and staying with friends. How can they get away with selling such an inferior product? After reading all these reviews, it looks like most everyone is very dissatisfied. I am more than happy to join a class action suit. Looks like a new boiler is going to cost me another $9,000. I am extremely frustrated.

Have problems with this boiler. The P1-140 is a piece of SH*T. This company sucks!

Very Unsatisfied

I replaced my scary old reliable 30 year old boiler in 2005 for $8000. The plumber didn't know what he was doing. I'm an embedded systems engineer and work on commercial boilers so I know my way around this kind of stuff. Flame would burn back through supply a/f tube. Very noisy and scary. Upgraded cpu, experimental burner assy, sensors over first two years. I've finally got the hang of it. Frequent cleanings, clean flame sensor, lot$ of gaskets. Adj air fuel by ear, manual specified %co no good. I generally get about 2 months between fiddles.

I bought this unit in the Fall of 2008 and have had to replace 2 control boards since then. Each time well over $1,000 to replace the boards. I would NOT recommend Peerless/Pinnacle equipment to anyone.
