Gas System Boilers

A system gas boiler provides heat to your central heating system and heats water stores in a hot water cylinder (which is usually situation in an airing cupboard). If you have 2 or more bathrooms, or require plentiful amounts of stored hot water, then a system boiler is more suitable than a combination boiler.

You can expect to pay anything from £600 up to £1200 for a domestic system gas boiler, but the costly market-leading brands such as Vaillant and Worcester Bosch have similar or identical inner parts to lower-priced models a lot of the time. Call our sales team to make sure you're getting the best deal.

BTU Calculator

Below is a tool that can enable you to calculate the BTU requirements needed for your room.

There are many factors that affect this calculation including the outdoor temperature, thickness of exterior walls and the quality of insulation installed. You should also ensure you have a boiler that is capable of generating necessary output for all of the radiators in your property.

Our BTU calculator should be used as a guide only, the actual BTU requirements may be slightly different to what our calculator will produce. If you need further help, please contact us.
