Bosch Thermotechnology Recalls Buderus Boilers Due to Carbon Monoxide Poisoning

Bosch Thermotechnology is recalling its Buderus GB125-35 oil-condensing boilers; the siphon can become blocked, leading to a delayed ignition that can damage the boiler’s exhaust system, creating a carbon monoxide hazard.

Consumers should immediately contact Bosch for a free repair: at 800-323-1943 from 8 a.m. to 6 p.m. ET Monday through Thursday, and Friday from 8 a.m. to 5 p.m. ET; via email at [email protected]; or online at www.bosch-thermotechnology.us/us/en/residential/home/ and click on the “Knowledge” tab, then click on “Product Approvals, Certifications & Regulatory Info” for more information.

Those who continue to use the boilers while awaiting repair should have a working carbon monoxide alarm installed outside of sleeping areas in the home.

This recall involves Buderus brand GB125-35 oil-condensing boilers distributed by Bosch.  The boilers have a blue enclosure and the GB125-35 model number is located on the data plate near the top right-hand side of the boiler.  The Buderus brand name is printed on the outside of the boiler’s blue enclosure. Bosch Thermotechnology and the model number are printed on a white label on the blue enclosure.

About 170 of the German-manufactured units were sold by wholesale distributors and installed by independent contractors nationwide from June 2008 through September 2012 for about $6,000.
