Buderus Wall Hung Boiler GB142 Requires Annual Maintenance

We are finding that the combustion chambers when not cleaned regularly can corrode and require replacement.

The residues from the fuel accumulate in the bottom and restrict the condensate drain. When this happens strong acids are formed which eat away the aluminum heat exchanger. This can be avoided by simply having the boiler serviced regularly by somebody that is trained on the unit.

This buildup can ruin the boiler!

    I've had the Buderus GB142 for several years. Most recent problem happened after we lost power in the house for just a few seconds. Since then it will not fire up and produce heat unless I press the middle button for a few seconds. It will run until the temperature reaches the thermostat set point. It then stops and won't start again until the middle button is pressed again.
    Do you know a trained Buderus plumber in RI?

    I'm sorry but I am in Seattle.
    Contact the local Bosch rep in your area for a referral.
