About the Waterstage Comfort series
The Waterstage Comfort series is a split air-to-water heat pump with a wall-mounted hydraulic module, for heating through underfloor heating or radiators. With an optional tank it also prepares domestic hot water, and the hydraulic module has a built-in backup electric heater. The controller sets the water temperature from a heating curve and the outdoor temperature, and with an optional kit it controls a lower and a higher temperature circuit separately, for example underfloor heating and radiators.
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.
