No hot water? Takes forever to heat up water? Short circuit blows fuses when you switch on the water heater?
Because it was working before does not means the circuit wiring is safe to reconnect. Plumbers do not have the electricians license to check the electrical circuit supplying the water heater, yes a plumber can drain down the water tank and replace the water heater element, but the final connection and electrical testing to confirm the circuit wiring is safe to reconnect should only be done by a licensed electrician with the correct test meter that covers insulation resistance, RCD test and earth loop impedance.
Limassol Electricians can carry out electrical fault finding on roof water tank immersion heater elements, and if need to carry out the replacement of the heating element.
We can upgrade your water heater switch with a time clock too, so you never have to worry about not having hot water in the winter months. Contact Limassol Electricians winter heating team and have your old element replaced with a long life Incoloy element.
