What size do I need?
Climate-aware sizing from country HDD, floor area and insulation grade.
Open →EPREL
Official EU energy-label registry. Every heat pump sold in the EU must be listed by its supplier — these are not marketing claims, they're the figures regulators see.
SCOP
Seasonal efficiency. 1 kWh electricity → SCOP kWh of heat over a heating season. 4.0 is competent, 4.5+ is good, 5.0+ is excellent.
Energy class
A++++ (APPP) is current top class for heating. Anything below A is uncompetitive. Cooling labels are separate.
