Rated heat output (Prated) of the supplementary heat pump (in kW)
Same explanation as for the the ‘rated heat output’ of the boiler, used above. In this case it refers to the suplementary (or secondary) heater, which is the heat pump. In the product label, it is indicated as the value fro the average climate on the bottom, next to the European map (temperature map displaying three indicative temperature zones).
Seasonal space heating energy efficiency of supplementary heat pump (in %)
Seasonal space heating energy efficiency’ means the ratio between the space heating demand for a designated heating season, supplied by a space heater and the annual energy consumption required to meet this demand, expressed in %. This value should be indicated in the 'product fiche' and is indicated as a value for average climatic conditions and temperatures, either 35° or 55°, based on actual load profile (i.e., the demand of the heating system). There are three options in terms climatic conditions: Colder (Northern Europe), Average (Central Europe), Warmer (Shouthern Europe).
