Visit our Heating your home page for more information on the heating systems in your home.

Can you check the power supply? Back to top

Check the heater is plugged in and switched on. If there is no power there might be a loose connection or wires out of place. An engineer will need to check this.

Have you checked the thermostat? Back to top

  • If safe to do so, remove the front cover of the heater to check if the thermostat is on. Check it is displaying the correct temperature or reset it if needed.
  • If the thermostat looks to be working then the problem may be the element. Please contact us as engineer will need to replace this.

Check the location of your heater Back to top

Immersion heaters that are located next to water tanks may not work effectively. Please contact us to discuss this. 

Do you live in a hard water area? Back to top

Immersion heaters do not work correctly in very hard water. An immersion heater that has been placed in a home with hard water may not work well.
