A piece of junk. Doesn't work, shuts down every day. No one around here knows anything about it. Worst piece of crap I ever wasted $$$ on. The manufacturer does not respond to help questions. Don't waste your money on this piece of shit!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I bought this boiler in 2008…nothing but constant problems. Stopped working yesterday in March 24, 2017 and parts to fix will cost 2,000.00. I will not fix it. I will get rid of this piece of junk. Supposed to be installed with expansion vessel but was not…constant leaked due to this the last 5 years. Constantly stopped working for water pressure issues, or pump issues…..went through 3 pumps, etc, etc. Please do not buy this product… is junk!!

"Baxi boiler is terrible"

Very Unsatisfied

I built a new home in upstate New York and my contractor talked me into a Baxi duo boiler. I have spent thousands of dollars on this piece of junk, replacing three control boards which are only warrantied for 90 days, a new fan, and several other parts, too. Why don't we start a class action lawsuit against them?

"Lacking in long-term reliability"

2.0 rating
Somewhat Unsatisfied

Positive: It takes very little space. It worked well for the first 7-8 years, so it seems to be properly installed. Negative: Difficulty in finding anyone who will work on Baxi. Most laugh and hang up. A very unpleasant winter, 2012/13, I spent $1300 in repairs/parts. It took months due to difficulty in obtaining parts. Less than two years later, the unit had the same problems with switching between heat and hot water and shutting off (except for the fan) in the midst of heating. Don't dare travel in winter without winterizing, as the boiler is not reliable for heat. Someone has to check on a daily basis! Saving money to replace it with a different brand!
