1. With the highest efficiency in producing domestic hot water, COP up to 4.3

2. CO2(R744) is natural gas, with ODP=0 GWP=1,it can minimize the impacts to environment

3. Monoblock design with high quality components

4. Easy operation, with touch screen interface.Modbus is integrated,can connected to wireless central control

5. Modular design, can be combined to get bigger capacity

6. CO2(R744)heat pump water heater can get same or higher COP than the conventional heat pump for heating and hot water combined system.

7. Can set temperature above 70℃, to kill the bacteria inside the buffer tank, more clean and more safe for the DHW
