All our central heating radiators have been fully tested according to European Standard EN 442 by an independent laboratory, so you can be confident that heat outputs shown on this website are accurate and reliable.

Outputs on the website are listed in watts and their imperial equivalent british thermal units (btus) and are shown at operating temperatures of 90/70/20 (ΔT=60K). Outputs at 75/65/20 (ΔT=50K) can be found on our Technical Data and Fitting sheets.
