Yes, it is possible to route solar heated water to an electric geyser inlet to achieve additional heating. This approach is known as a solar water heating system with electric backup.
In such a system, solar collectors, typically installed on the roof or in an area with ample sunlight exposure, capture the heat from solar radiation and transfer it to the water circulating through the collectors. This solar heated water is then directed to the electric geyser's inlet, where it enters the tank.
The electric geyser, or water heater, is equipped with an electric heating element that can further increase the temperature of the water if needed. If the temperature of the water supplied by the solar collectors is not sufficient for the desired hot water temperature, the electric heating element in the geyser can activate to provide additional heating and raise the water temperature to the desired level.
The advantage of such a system is that it utilizes the free energy from the sun to heat the water, reducing the reliance on electricity or other conventional heating methods. It can result in energy savings and lower utility bills, particularly in sunny regions where solar radiation is abundant.
It's worth noting that the specifics of integrating a solar water heating system with an electric geyser may vary depending on the design and components of the system. It is recommended to consult with a professional or a qualified installer to ensure proper installation and compatibility of the components for safe and efficient operation.
