About the Waterstage DHW High Power series

The Waterstage DHW High Power series is a split air-to-water heat pump whose hydraulic module has a built-in 190-litre domestic hot water tank, for underfloor or radiator heating. 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	10 kW	9.6 kW	8.05 kW
−15 °C	12.1 kW	10.74 kW	9.44 kW
−10 °C	12.16 kW	10.74 kW	9.85 kW
−7 °C	12.2 kW	10.74 kW	10.1 kW
−5 °C	12.38 kW	11.04 kW	10.21 kW
0 °C	12.82 kW	11.8 kW	10.49 kW
7 °C	13.5 kW	12.1 kW	10.6 kW
