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 800mm-wide black towel radiators with 750mm 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 400mm to 600mm; check availability on each product. Check the full wall width and access around nearby fittings before ordering a wider rail. A lower-height model may fit beneath an obstruction, but its heat output still needs to meet the room’s requirement.

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.
