Quick BTU calculator

Enter your room measurements for an estimated heating requirement. Compare radiators without leaving this page.

Starting assumptions: two adjacent outside walls, 1.5m² low-E glazing, insulated cavity walls, ground floor and insulated loft. Check these against your room.

Check or change room assumptions

U-values describe heat passing through a surface; use known building values where available. −3°C outdoors, 10°C below and the default U-values are preliminary assumptions, not a location survey. Unheated lofts use the outdoor temperature; heated floors/ceilings use U 1.36/1.62 and the adjacent-room temperature.

Preliminary rectangular-room estimate, not an installer’s heat-loss survey. It excludes detailed thermal bridging, ground/loft modelling and ventilation-system design. Confirm the room heat loss and radiator output at your heating-system temperatures before ordering.
