Separated and pressure solar water heater.
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.
