24KW - 27KW
As a rough estimate most flats, apartments and smaller houses with up to ten average size radiators will require a 24 to 27kW combi boiler. Larger properties with a higher demand for hot water are likely to be more suited to a 28 to 34kW or 35 to 42kW combi boiler. This information is only a guide, but will give you a good idea when discussing your needs with a heating engineer.
