Replacing the heating element (original or compatible, depending on the model)
Electric Water Heater Repair
Electric water heater repair: no heat, a tripping breaker, leaks or a dripping safety valve. Element, thermostat and earth checks; 6-month written warranty. An electric heater has no gas-leak risk, but its safety depends on a proper earth and a working safety valve. Its drawbacks: a higher electricity bill, heat-up time and limited capacity — it suits apartments without a gas supply.

An electric water heater works with a heating element immersed in the water and a thermostat that controls the temperature; inside the tank an anode rod protects it from rust, and a safety valve sits on the inlet. The most common faults: a burnt-out element, a faulty thermostat, or scale on the element. Brands we work on include Olympic Electric, Ariston, Rheem, Bosch, Ecomatic and Fresh.
Signs your Electric Water Heater needs service
- The heater does not heat the water at all
- The water is lukewarm, not hot

- A strange noise from inside the tank
- Water leaking from the base of the heater

Tips to keep your Electric Water Heater running
- Set the thermostat to 55–60°C — anything higher wastes electricity and can scald
- Drain and descale the heater once a year: switch off the power and let the water cool, and only switch it back on once the tank is full again
- A sudden jump in the bill may point to the thermostat — check that the heater switches itself off at temperature
- Make sure the heater is on a sound earth and an RCD
- If the safety valve drips constantly, never plug it — it is what protects the tank from bursting; a small drip while heating can be normal, but a constant one needs a technician to check the pressure and thermostat

Electric Water Heater — frequently asked questions
The heater does not heat at all — what is the cause?
Usually a burnt-out heating element — the technician confirms it with a multimeter, and replacing it is one of the simpler heater repairs. First check that the breaker is on and the tank is full of water.
The electricity bill jumped suddenly — is the heater the cause?
It can be. If the thermostat is faulty, the heater keeps running instead of switching off at temperature, which can raise the bill noticeably. If the water is scalding, steaming or you hear boiling, switch the heater off at once and call a technician.
The breaker trips when I turn the heater on — what is the cause?
Usually the heating element is shorting to earth. This is dangerous: switch the heater off immediately and call a technician — using it like this could make the shower water live.
What is the best temperature for the heater?
55–60°C is enough for showering and killing bacteria. Higher temperatures waste electricity for no benefit and can scald.
What is the lifespan of an electric heater?
Roughly 8–12 years with regular servicing, and the element itself may be replaced more than once in that time.
Do you install electric heaters of any capacity?
Yes — from 30 litres for small bathrooms to 150 litres for villas. Installation includes the water and electrical connections on a proper earth.
