How the visit works
We diagnose the Vaillant gas valve and ramp pressure if the flame will not hold.
We inspect the secondary exchanger and Buderus diverter when there is no DHW.
We read the Rinnai board fault and test sensors before any module swap.
Topic 1 / 3
If radiators stay lukewarm, the boiler is slow to heat, or it short-cycles — scale in the heat exchanger is a common cause. It cuts heat transfer, raises gas consumption, and can overheat the unit.
On diagnostics the technician flushes the primary and secondary exchangers, checks temperature sensors and the return filter. We agree the scope and price before cleaning starts.
Tell us the model and fault code — we'll advise on a home visit and prepare for diagnostics.
