Bosch is recalling approximately 170 Buderus brand GB125-35 oil-condensing boilers because a component called a siphon can become blocked. This blockage leads to delayed ignition that can damage the boiler's exhaust system and leak carbon monoxide into the home. These units were sold at wholesale distributors and installed by contractors nationwide between June 2008 and September 2012 for about $6,000. Bosch is providing a free repair for all affected units.
The blocked siphon causes delayed ignition that can rupture or damage the exhaust system, allowing dangerous carbon monoxide gas to escape. No injuries or incidents have been reported in the U.S. to date.
Consumers should immediately contact Bosch for a free repair. Consumers who continue to use the boilers while awaiting repair should have a working carbon monoxide alarm installed outside of sleeping areas in the home.
