Buderus Logamax Plus GB142 Boiler Overview

We've had our Buderus boiler since 2007 and heat about 4200 sq. Ft. With it. It is in a separate building that is 16x 24 and this is part of the total sq. Footage that is heated. There are filters on the return line and it is running with about a 50% glycol mix with the city of Saskatoon water. I try to run it with a 7 ph level. On an annual basis, I dismantle the boiler and do a fairly thorough cleaning. I must say that other then a few glitches I've had no trouble with it. A Couple of former co-workers and myself installed the system ourselves, one being a plumber/ gas fitter and the other being in energy management. I myself being an electrician. By reading the reviews I see I'm in the minority as far as customer satisfaction is concerned.

Started having problems in the second heating season. Parts are double what you would pay for other brands. Sensors, fan, air relief at the top, all went by year three. By year four manifold was leaking at seals, oval ring in back vent disintegrated. Had to have the whole unit removed for that. By year five a hole developed in the back case. Not the exchanger. Leaked water and carbon monoxide into the house. Finally had it removed. In a lifetime I will never earn back money that would have been saved in efficiency. Cleaned twice a year by service. Besides the cost of the unit, I spent probably close to 5k keeping it running for 5 years. Buderus, now Bosch was zero help. They gave up on these years ago.

No one to service – States there is no fixing leaks!!

I thought we just had a lemon until I looked online. No one has anything good to say about the Buderus 142 series wall mounted boilers. A nightmare to disassemble and clean–which we need to do twice a season. Even then, you can't get it clean enough to be efficient. In less than seven years it has eroded the heat transfer fins almost completely away. Add me to the list of completely dissatisfied customers. Looking for a replacement that is better engineered for maintenance and longevity. Terrible product.

Installed 2009. Still under warranty, but Bosch will not honor it. Leaking. 3 people came to look at it — all of them said this is not a good system. All of them said I should replace rather than fix.
