Unvented Hot Water Cylinder Service £80 Inclusive of VAT

If you live in one of the larger new build properties, you’ll have noticed that the heating system differs from the common combination boiler type. In fact, the vast majority of larger newly built houses will have what’s known as an Unvented Hot Water Cylinder System as its source of hot water.

This type of system takes the cold water supply directly from the mains water pipe rather than from a gravity fed tank or by being connected to a pump and is the more efficient option for larger houses with a high demand on hot water. An unvented cylinder service is a different procedure than a standard combination boiler and features, amongst other things, safety valve testing, pressure vessel recharging, pressure reduction valve cleaning and electrical connection checking. And as you are probably assuming, there are qualifications that need to be met for carrying out unvented cylinder servicing. Our engineers are G3 Qualified and will competently, safely and professionally undertake your unvented cylinder system service.

We advise that annual servicing is carried out in order to maintain the following three levels of water temperature safety…

  • Thermostats that prevent the water being heated above 60 – 65°

  • Temperature relief valve if the water reaches 90 – 95° (should other safety features fail)

It’s also handy to know that many home insurers insist on an annual service of Unvented Cylinder Systems in order to maintain the integrity of your policy should you require cover for damage caused.
