The main forms of heating boiler are:-

Gas Fired back boilers

It is not uncommon to find back boilers in older housing stock, being fitted in the chimney they were sheltered from view, with a fire in front to conceal them. Low water pressure is a problem with these gas back boilers and you will not be putting in one of these unless it is a substitute, they want a lot of space and you will need someplace to hide your boiler.

Open vent central heating gas fired boilers

Most families will have an open vent gas boiler installed. They come with 2 water storage tanks to be installed in the loft., additional space is also called for for the hot water storage tank fitted in the airing cupboard.

Mains supply water is fed via one of loft storage tanks to the hot water storage tank.

The second is called the expansion and feed and this enables the water in your system to expand and contract. Many taps or showers and baths can be run simultaneously but the hot water cylinder does have a finite capacity.
