As a rough guide, allow about 120 watts per square metre in a well-insulated room, 140 in an average one and 160 in an older, draughty one. A 30 m² lounge works out at about 4.2 kW with average insulation and 4.8 kW if it loses heat. Heat pumps come in set sizes, so both round up to a 5 kW unit. Use the calculator above for your room, then have an installer confirm it.
