Ranked by COP at the standard EN 14511 rating point A7/W35 (7°C outdoor air, 35°C leaving water). COP is a single-point snapshot, so read it alongside SCOP — but it is the most widely published efficiency figure. Only products with a COP quoted at A7/W35 are included.
Every figure comes from the manufacturer’s published specification as recorded in the Heat Pump Database; near-identical variants (e.g. single- and three-phase versions with the same result) are shown once. The list updates automatically as new products are added.
