Domestic Gas Boilers: Combi, System, Heat Only

There are 3 main types of domestic gas boiler available - combination, system, and open vent / heat only. We list one of the largest ranges of boilers on the Internet, at the lowest trade prices as standard. New legislation has meant that all gas boilers now have to be SEDBUK A-rated, which is over 90% efficient, meaning your new boiler could save you large amounts on your heating bills.

Gas Combi Boilers

HEATING AND INSTANT HOT WATER
A combination boiler is designed to be a central heating boiler and water heater all-in-one. The stand-alone unit will power your central heating and domestic hot water on demand without the need for a cylinder.

Gas System Boilers

USE WITH A COLD MAINS SUPPLY
Designed to work with a sealed hot water cylinder and cold mains supply. If you have two or more bathrooms, or have high stored water requirements, a system boiler is your best option.

Gas Heat Only Boilers

USE WITH A WATER TANK IN LOFT
Designed to work with a hot water cylinder and stored water, usually via a feed and expansion tank in the loft. These boilers are best-suited to those with a traditional heating system already installed.

External Gas Boilers

SUITABLE FOR SITING ON A BALCONY
There may be times when space or flueing constraints mean that you cannot install a boiler indoors. These models are suitable for installations outdoors with the use of a galvanised case.
