Combi Boiler Suppliers

Choosing a Combi Boiler 

Combi (or combination) boilers are great ways to power a heating system and keep the household nice and warm. Combi boilers use the mains water pressure to supply both hot water and heating according to demand. Combi boiler does not require additional water tank or cylinder, which makes it a good option for smaller properties. A new, A-rated high-efficiency combi boiler could save you more than £300 in a year on your energy bills.

It can be an expensive business to keep a large property warm during the winter months, and a lot of warmth can get wasted with options like gas, but an electric combi boiler is going to be 100 per cent energy-efficient. Also, electricity tends to be cheaper than other types of fuels, so there is a way to make some real savings!

An electric combi boiler would be a great addition to your household, especially if you consider combining it with panel heaters. Panel heaters are great since they offer a cost-effective way of heating up a large house. The combination of combi boilers with panel heaters will benefit your home by heating the space rapidly and cost-efficiently.
