What Is an Immersion Heater?
The immersion heater can also be described as an electrical water heater that is installed within the hot water cylinder. It acts as a kettle, heating the tank’s water by means of the use of an electrical element. It could be your primary hot water source or even a backup in the event of problems with your boiler.
Common Reasons Why Your Immersion Heater Isn’t Working
Identifying the issue starts with knowing the possible causes. Here are the top reasons:
- Faulty Thermostat
If the water isn’t heating, the thermostat could be stuck or broken. - Burned Heating Element
Over time, the heating element inside can degrade and stop working. - Tripped Switch or Fuse
Electrical faults can cause the immersion heater switch or fuse to trip. - Limescale Build-Up
In hard water areas like London, limescale can collect on the element, affecting performance. - Loose Wiring or Connections
Faulty or loose electrical connections can disrupt power flow to the heater. - Old or Outdated Unit
If your heater is older than 10 years, it may need a complete replacement.
