  1. No one hurt

    Made Apr 12, 2020, sent to the company May 6, 2020, published by CPSC May 20, 2020

    The product, in the report: Bosch Buderus SSB120 Boiler

    This incident happened on two of these boilers. Once on about 11/9/19 and then again on 4/10/20. The first boiler was installed in December of 2018 and the second in November of 2019.

    The first boiler was replaced under warranty by Bosch and they had the unit shipped back to their offices for examination. The second unit has been shut off and we are waiting for resolution.

    The boiler chamber where the gas is ignited appears to have a flaw. When burning the the side of the boiler chamber inside the boiler heats up so much that it glows bright orange. Bosch confirmed this is not supposed to happen. It melts the wiring inside the unit. It has also melted the insulation inside the boiler. The first unit stopped working because the wiring was melted completely. The second unit we caught the issues as we smelled and saw smoke from the unit.

    This is a major fire hazard, Most people would never check on their boilers. These run at all hours and I would hate to think what would have happened if this caught fire while we were sleeping.

    There must be a design or manufacturing flaw as we have had the exact same issue happen on two boilers. We have photos of the boilers.

    The product, in the report: Bosch GB-142 gas boiler

    I had my GB-142 installed in 2012 and registered it online with you (Registration ID [REDACTED]). You should have my Serial Number and such on file. It was installed by one of your authorized agents. I have had numerous problems with it even though I have had it meticulously maintained, and have needed it repaired numerous times over its short life so far.

    I work at home and have had numerous bouts of headaches this winter, but the furnace seemed to be working properly. When Rowell Service of Franklin NH came in to do a routine annual cleaning of the furnace last week, the serviceman said he smelled something as soon as he entered our basement, and then found that the exhaust tube exiting the furnace had a large hole corroded through it, allowing the furnace to push its exhaust gases directly into our home….That explains all of my headaches. He put a temporary patch over the hole and told me parts needed to by ordered to repair it. Relatedly, the acidic dripping from the hole into the furnace had caused the need for additional internal repairs. And that dripping turned out to be the cause of the leaking onto the basement floor which we though was leaking pipe fittings that a different plumber was unable to repair last Spring… indicating that the problem was present but unnoticed since at least last winter.

    Rowell called back the next day back to explain that the repairs with labor were going to exceed $1000. Having no other choice, I authorized them to order the parts. Rowell called today to say that when the parts came in, the vent adaptor was not included. So they did some research and found that this corrosion is an epidemic problem with this furnace and (as they heard though the grapevine) was the subject of a supposed recall. The first part of that turned out to be true but the second didn’t… it is clearly an epidemic problem, but amazingly is not the subject of a recall (yet).

    I called to your customer service line and was told of your Product Notice https://www.bosch-climate.us/files/PIN_GB142_Vent_Adaptor_Inspection_US.pdf and the available “free” replacement vent adaptor (and about the tedious process I’d need to go through to get it and then have it installed at my expense).
