Immersion Heater Replacement
Immersion Heater Replacement
Immersion heater replacement in Barnet and North London — a common cause of no hot water, usually fixed in under two hours.
Immersion Heater Replacement in North London, done properly the first time
If your cylinder has stopped heating but the boiler is fine, the immersion element or its thermostat is the usual culprit. Elements scale up and burn out, particularly in North London's hard water.
We test before replacing, fit an Incoloy element where water hardness justifies it, and check the cylinder thermostat and wiring at the same time.
Most jobs are completed on the first visit with the part carried on the van.
