Viessmann 100-W WB1B PCB 26kW/30kW/35kW – Refurbished | Part No. 7832516

A Viessmann 100-W WB1B boiler that fails to ignite, loses heating or hot water output, or shows persistent fault codes often needs a PCB replacement.

This refurbished unit is taken from a fully functioning boiler and quality-checked by our experienced engineering team to the highest standard before dispatch. Minor cosmetic marks may be present, but all functional performance is confirmed. Available for both Combi and System boiler types — please select the correct type when ordering. Supplied with a full 12-month warranty.
