WATER HEATERS SUITABLE FOR SUN PANEL SYSTEMS
Despite of water heaters main usage for providing a domestic hot water or heating, they accumulate the absorbed by the solar panel sun energy. The coil heat exchanger transfer the heat energy of the solar panel to the heat energy of the water in the water heater by means of the circulation fluid in the pipe system.
As a result of that the heated water can be used either as a domestic hot water or for a heating. The vertical standing water heaters are with better performance and therefore, they are the most preferred ones.
