WATERSTAGE™ ATW Systems Split DHW Integrated Type High Power Series
High leaving water temperature
The temperature of leaving water can be kept at 60°C, even when the outdoor temperature falls to -20°C.
- If you want to raise the temperature of the water supply to above 60°C, use a backup heater to supplement the primary heater.
High coefficient of performance (COP)
Heat pumps of WATERSTAGE™ ATW Systems work more efficiently and consume less energy than conventional heating systems.
2-zone individual control
2-zone individual control of, for example, 2 underfloor heating zones or the combination of 1 underfloor heating zone and 1 radiator zone
*Optional parts required
Automatic heating curve control
Automatic temperature regulation according to a heating curve (depending on a heating terminal and outdoor temperature)
- Anti-corrosion protection
- No flow switch required
- Anti-freeze protection not required
If an outdoor unit fails to operate, a built-in backup heater or an external boiler is activated to supply hot water to the house uninterrupted.
