Contact details
(1) For heat pump space heaters and heat pump combination heaters, the rated heat output Prated is equal to
the design load for heating Pdesignh, and the rated heat output of a supplementary heater Psup is equal to
the supplementary capacity for heating sup(Tj).
(2) If Cdh is not determined by measurement then the default degradation coefficient is Cdh = 0,9.
