28KW - 34KW

As a rough guide when reviewing your heating needs, a medium to large semi or detached house with up to 15 average size radiators will require a 28 to 34kW combi boiler. Most flats and smaller... houses only need a 24 to 27kW boiler, while larger properties with a higher demand for hot water are generally more suited to a 35 to 42kW boiler.
