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!
