 A Combi or “combination boiler”, is a single compact, high efficiency unit that heats your central heating water to your radiators and also the hot water coming from your taps. There is no airing cupboard for a hot water store so you will not have a cylinder.

A Conventional Boiler System, also known as a Regular or Heat Only Boiler. These systems have typically two header tanks in the attic and a hot water store, typically a copper cylinder, in an airing cupboard. You will currently have to program your heating and hot water to come on. The hot water system can also be referred to as “gravity fed”.

System Boilers

A system boiler can sometimes cause a little confusion with a conventional system as they hold a couple of similar characteristics. Firstly they both have a separate hot water store. System boilers typically have an unvented water store, usually in the form of a large white vessel in an airing cupboard that can be up to two and a half meters tall. A system boiler is pressured so will have a small pressure gauge on the front of the boiler and need topping up via a “filling loop” every now and then.
