Newly design heat pump water heater: (air to water typeall in one design). 1. Double energy system by air source technology and smart electric water integrated technology. 2. All in one design, easy installation, save space. 3. Safety, the electricity is completely separated from water, without any poisonous gas, liquid or trash letting while running. 4. Save energy , saving more energy by 70% comparing with ordinary water heater. 5. Protecting Environment. There isn't any burning gas from the water heater. The refrigerant won't contaminate the ozonosphere. So it benefits the society. 6. Supply water anytime, and not be affected by geographical and weather changing. 7. Intelligent control, the water temperature can be adjusted as needed and controlled by micro-computer automatically.
