t50 is the UK’s industry standard for heating outputs, which has an operating temperature of 75/65/20ºC. If you have a low temperature
heat source you may wish to consider t40 or t30 output (see your installer or system designer or download from stelradprofessional.com).
For EN442 data, technical and installation information please visit stelradprofessional.com and search product downloads.
For systems not operating at DeltaT 50 the correction factors table on page 114 should be applied.
Stelrad.
Fit for the future.
Stelrad Radiators are ready for decarbonisation and
have many radiators being specified more and more
for renewable heating systems as the popularity
of heat pumps rises in the UK and Ireland.
Radiators continue to provide the levels of heat
required when correctly sized, and the extended
K3 and vertical ranges, plus the new Compact 900
high models are ideal for adhering to the new
Part L regulations, which dictate a maximum flow
temperature of 55° in new buildings.
FULLY COMPATIBLE
WITH NEW LOW
TEMPERATURE

Stelrad’s range of high output radiators are aesthetically
designed to meet your installation, specification and
contract needs, now and in the future.
