What's ATW (Air to Water)
WATERSTAGE™ is a safe, comfortable, and efficient water heating system by adopting heat pump technology that utilizes the heat in the air.
This system provides support for space heating and water heating.
This WATERSTAGE™ uses very little electric energy to efficiently absorb heat from the atmosphere by adopting an inverter heat pump. A small environmental load heat source system can be economically realized by using this heat energy to produce hot water for radiator, floor heating or domestic hot water.

Heat Pump is most efficiency system

Absorbing the free energy from atmosphere.
Heat pump system requires only 1kW of electricity to generate 3 to 5 kW thermal energy.
