How solar water heater works.
This solar water heating system consists of four main parts the solar collectors the solar pump station the solar storage tank and the plumbing for the heat transfer.
The proper installation of solar water heaters depends on many factors.
It is distributed over underfloor heating systems or heaters.

Open loop system.
Initial solar water heaters were basically large metal containers painted in black because black color is a good conductor of heat and absorbs a lot of heat getting heated quickly.
Solar water heaters are described according to the type of collector and the circulation system used.
Dhw radiant.
When the controller senses that the sun is shining and your tank needs a warm up it signals the pump to send water through the black collector panels.
