Water Heater Repair & Installation — Electric & Solar
No hot water on a cold morning, or a tank that's started leaking — FETSCO installs and repairs electric storage water heaters, instant heaters and solar water-heating systems.
Common Water Heater problems we fix
Common issue
No hot water at all
Likely cause: A tripped breaker, a blown heating element, or a faulty thermostat — for solar systems, it can also be a circulation pump fault.
How we fix it — We test the element and thermostat (electric) or the pump and controller (solar), and replace whichever has failed.
Common issue
Water not hot enough / lukewarm
Likely cause: A failing lower heating element, a sediment-fouled tank reducing efficiency, or an undersized thermostat setting.
How we fix it — We test both elements independently, flush sediment build-up from the tank, and correct the thermostat setting.
Common issue
Water heater leaking
Likely cause: A failed pressure relief valve, a corroded tank, or a loose fitting.
How we fix it — We identify the exact leak point — a valve or fitting is a straightforward repair; a corroded tank usually means replacement, which we'll advise on plainly.
Common issue
Water heater making banging/popping noises
Likely cause: Sediment build-up at the bottom of the tank causing water to boil under the layer.
How we fix it — We flush the tank to clear sediment, which resolves the noise in most cases.
How we install your water heater
Sizing & placement
We size the unit to your household's hot-water demand and confirm safe placement and access for future maintenance.
Plumbing connection
Inlet, outlet and pressure relief valve connected and pressure-tested.
Electrical or solar circulation setup
Electric units wired to a dedicated, correctly-rated circuit; solar systems have the circulation pump and controller set up and calibrated.
Heat-up & safety test
We run the unit to full temperature and confirm the pressure relief valve and thermostat cut-out both work correctly before handover.
