Common Electromax faults we fix
The Electromax combines an economy off-peak bottom element and an upper boost element. When lower elements burn out or scale up, water fails to heat overnight on cheaper tariffs. We also regularly fix blown internal fuses within the water heating switch compartment—a distinct issue that shuts down water heating even while main panel lights stay lit.
Why choose our dedicated specialists
Because the Heatrae Sadia Electromax integrates an electric flow boiler with a high-pressure unvented hot water storage cylinder, standard gas engineers and general plumbers often lack the specialised training required to diagnose it safely. Our London team carries genuine replacement parts and advanced electrical diagnostics to complete repairs on the very first visit.
