The right Combi Boilers size for you.

When we talk about boiler size, we do not mean its dimensions, but rather its power output.

The unit of measurement, used for Combi Boilers, is the kilowatt (kW). To clarify, the bigger the kilowatts, the greater the capacity of the boiler to match your demands for hot water and central heating.

We advise that you get a small (low power) combi boiler if you have a small home with only one bathroom.

On the other hand, you will need a much bigger boiler if you live in larger property with more than one bathroom.
