What we check before recommending parts
Electric heating faults can be upstream of the appliance. We test in a logical order and keep repair versus replacement as a decision made after evidence, not before.

Frequently asked questions
Can you replace just the thermostat?
Yes, where testing confirms the thermostat is the fault and the element/cylinder are serviceable.
Why does the RCD trip when the immersion heats?
An element can leak current to earth as it deteriorates. Insulation testing helps confirm whether the element is the cause.
Can you repair Economy 7 hot water?
Yes. We test both the off-peak electrical supply and the immersion/cylinder controls.
