About the Waterstage Super High Power series
The Waterstage Super High Power series is a split air-to-water heat pump with a wall-mounted hydraulic module, which the manufacturer recommends for renovation: older or poorly insulated houses and large rooms. It works with radiators and underfloor heating and, according to the manufacturer, holds a high flow temperature without the backup heater even at very low outdoor temperatures. With an optional tank it also prepares domestic hot water. Control follows a heating curve automatically, and with optional parts underfloor heating and radiators are controlled separately.
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.
