Gas and Oil Boiler types

Combination Boilers

Combination Boilers

Combination Boilers


A combi boiler, also known as a combination boiler, is a type of condensing boiler. Combi boilers are highly efficient and compact, making them ideal for smaller homes. 

The name Combi comes from the fact that these boilers are able to act as both a water heater and also a central heating unit. Combination  boilers are one of the most popular choices today.

Combi boilers work by heating water directly from the mains incoming water, so you don’t need a hot water storage cylinder or cold water tank. This is ideal for smaller properties without airing cupboard or roof space. This heating method also makes them very energy efficient and affordable to run, as water is not heated and stored.

 Combination boilers have some great advantages.

Heat Only Boilers

Combination Boilers

Combination Boilers


Also known as a regular boiler, a regular boiler system is made up of a number of parts including a boiler, heating controls, a hot water cylinder, a cold water storage cistern plus a feed and expansion cistern. A regular boiler can often be found in older, larger homes and less are being installed.

A Regular boiler system is fed by two tanks which are located in the loft. One of these, the cold water storage tank, draws cold water from the mains supply. The other is the feed and expansion tank, which feeds the boiler system and manages any water that expands in the system after being heated.

System Boilers

Combination Boilers

System Boilers


A system boiler directly heats your central heating and also produces hot water for your storage cylinder. It is a heat only boiler and works in a similar way to a regular boiler, however it does not require a feed and expansion tank in the loft as the heating system is pressurised.

A hot water storage tank will always be required with a system boiler, as it needs somewhere to store the water it has heated. A system boiler is also suitable for smaller homes than a regular boiler.

If you combine this type of boiler with a pressurised hot water cylinder you can also then have stored pressurised hot water which then does not require no tanks in the loft.
