Heating & Hot Water
Hot Water Cylinders & Immersion Heaters in Watford & Hertfordshire
Running out of hot water, or a cylinder that is old and leaking? We replace vented cylinders and repair or replace immersion heaters.
Many homes with regular boilers store hot water in a vented cylinder fed from a cold water tank in the loft. Over time cylinders can corrode, leak or lose their insulation, and immersion heaters can fail.
We replace vented cylinders, fit new immersion heaters and thermostats, and fix the valves and controls around them. If you are thinking about changing the whole system, for example to a combi, we can talk you through the options.
