(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.
