Unvented Hot Water -

This is a system often specified by home makers who want a versatile output but need to save as much space as possible. An unvented hot water cylinder means there is no need for a cold water storage tank whilst still keeping all the benefits of a conventional system and more.

All you need is to site your gas central heating boiler in your property, position the unvented hot water cylinder (normally in the airing cupboard) and connect the two together and add your controls and an expansion vessel.

This means there are no tanks in the loft area, loft space is saved. An airing cupboard contains the hot water cylinder.

This system kit is quite expensive compared with a normal conventional system or a combination boiler. You'll definitely need a well skilled installer for this installation which we can supply.

Unvented cylinders shown come in a range of sizes.
