Heating & Hot Water
Hot Water Cylinders & Immersion Heaters in North & West London
No hot water, lukewarm water or a cylinder that has seen better days. We repair and replace vented cylinders and immersion heaters, and sort out hot water problems.

Many London homes still have a hot water cylinder in an airing cupboard, fed by a cold water tank in the loft. When the hot water stops working properly, the cause is often the immersion heater, the cylinder thermostat, a valve, or the cylinder itself.
We diagnose the problem, replace immersion heaters and thermostats, and replace vented cylinders. If your home would suit a different setup, such as a combi boiler, we explain the options honestly.

What affects the price
The cost depends on whether it is a part, like an immersion heater, or the whole cylinder. We diagnose the fault and agree the price before starting.
“Andres and his team replaced our boiler and hot water cylinder and replaced a lot of our old pipework. They started the work on the day they said they would and completed most of the work in two and a half days.”

Questions
Hot Water Cylinders: common questions
Why have I got no hot water but the heating works?
Common causes are a faulty diverter or zone valve, a cylinder thermostat, or the hot water timer. We find the fault and fix it.
Can you replace my immersion heater?
Yes. We replace immersion heater elements and thermostats in vented cylinders.
Do you install unvented cylinders?
Our hot water cylinder work covers vented (tank-fed) cylinders and immersion heaters. If an unvented cylinder suits your home, we will discuss the options with you.
