High pressure split solar heating system separated solar water heater

  Feature:

1. the pressure tank can keep the water hot during the night.

2. the tank and work station can be put in the basement or house, and the solar collector is installed on the    roof. It is perfect combination for the apartment or villa.

3. as the tank is in the house, you can set the temperature, water level and other parameters by yourself, so it is very convenient.

 4. there is electric heater to support, and it could start automatically if no sunshine.

 High pressure split solar heating system separated solar water heater

Principle:

Firstly, vacuum tubes absorb sunlight, and then transfer heat to manifold by supper

conduct heat pipe which has heat transfer medium in it, and heat the water in manifold.

 Secondly, it starts to get forced circulation between manifold and tank by circulating heat pump,hotter water flow into tank and cold water flow into manifold( because water temperature between manifold and tank is different, moreover, collector and tank is separated ,so we need circulating pump ). In addition, there is copper coil in tank, which will start to exchange heat when water in tank gets heat by circulation,so the water will be hotter and hotter by circulation and heat exchange. This circulation continues because of different water temperature between tank and manifold.

 At last, when water temperature difference between tank and manifold is lower than set temperature, circulation will shut off.
