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.
We recommend TRV Valves to complete the
look. See page 117 for more information.
