Combi Oil Boilers

Heating your hot water system with oil instead of gas is a great alternative. Combination boilers are a particularly fine choice as they do away with the need for a hot water cylinder or water tank. Instead, water is heated through a central heating boiler that incorporates a highly efficient water heater. The combination of the two means less space is taken up in your home, which is always a winning situation.

If you prefer to use oil, you'll find that Heat and Plumb stock a range of oil combi boilers from highly-regarded brands such as Firebird, Eurocal, and Warmflow.

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.
