What we test
The boiler is part of a complete system.
We follow the fault from the electrical supply and controls through to the boiler and wet heating system. That matters because a failed thermostat, valve, pump, sensor or circuit can produce the same symptom as a boiler component fault.
- Incoming supply, protective device and dedicated circuit
- Programmer, thermostat, receiver and demand signal
- Boiler components, pressure and circulation
- Hot-water cylinder and zone controls where connected
