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.

Choose white towel radiators by width and height, then compare the listed heat output and pipe centres. Use the finish to coordinate with your bathroom fittings.

White gives a simple finish alongside white sanitaryware. Check the individual product’s height and options before ordering, especially when replacing an existing rail.

Pipe centres are 50mm less than the radiator width. Wall brackets, an air vent and a blanking plug are included; valves are optional. Heating performance depends on the chosen model and system temperature.
