Double Energy-saving System Devices: are Air Source Heat Pump Water Heaters combining solar energy.
System Devices:Six pieces of flatbed solar energy heat collectors, 1 HP-1600 Suntech Air Source Heat Pump Water heater, and a 1T insulation barrel.
System Programming:：
Flatbed Solar Heat Collectors: They absorb the sunlight to produce hot water and store it in a 1T hot water insulating barrel; during the winter, the water temperature may reach 40 to 50°C, while it may reach 60 to 70°C during the summer. After that, the hot water shall be provided from the 1T insulating barrel to the boiler insulating barrel, so that to lower the fuel cost of gas boilers.
Suntech Air Source Heat Pump Water Heaters: They produce hot water (about 55 to 60°C) and store in the 1T hot water insulating barrel during the off-peak hours at night; after that, the hot water will be transferred to the boiler insulating barrel, so that when the device is operating during the day, it is possible to lower both the fuel cost and the operating time of the boiler.
