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.

Read guide

Compare 400mm-wide black towel radiators with 350mm pipe centres. Choose a height that fits your wall and check the listed heat output for your room.

Listed heights in this collection range from 600mm to 1800mm; check availability on each product. Measure the wall between nearby fittings and leave clearance for the valves. Matching the radiator width alone does not guarantee that it will fit existing pipework.

Wall brackets, an air vent and a blanking plug are included with towel radiators. Valves are optional. Ask your installer to confirm the connections and any electric or dual-fuel requirements.
