Choosing the right size

How much heat a room needs depends on its size, insulation, windows and how warm you like it. Use our BTU calculator to estimate what the room needs, then choose a size from the options on this page. If you are comparing radiators from different ranges or brands, compare their outputs at the same ΔT (the difference between the average water temperature and the room temperature). Our guide to radiator terms explains what ΔT and BTU mean, and our help choosing a radiator page has more guidance.
