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 | 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 |
