About the Waterstage High Power series

The Waterstage High Power series is a split air-to-water heat pump for underfloor or radiator heating and domestic hot water. The hydraulic module is wall-mounted and prepares domestic hot water with an optional separate tank. According to the manufacturer, it holds a high flow temperature without the backup heater even at very low outdoor temperatures, and it recommends the series for new builds and renovations alike. Control follows a heating curve, and if the outdoor unit fails, the built-in backup heater or a connected boiler takes over.

Heating capacity by outdoor temperature

The manufacturer's data from the design & technical manual: the maximum heating capacity at the outdoor temperature and the water temperature of the system. The calculator chooses a model by this table; the certified data above is what was measured independently.

Outdoor	Water 35 °C	Water 45 °C	Water 55 °C
−20 °C	9.89 kW	8.66 kW	6.7 kW
−15 °C	10.38 kW	9.98 kW	8.1 kW
−10 °C	10.38 kW	9.98 kW	8.83 kW
−7 °C	10.38 kW	9.98 kW	9.27 kW
−5 °C	10.47 kW	9.96 kW	9.28 kW
0 °C	10.68 kW	9.92 kW	9.29 kW
7 °C	10.8 kW	9.9 kW	9.29 kW
