Solar domestic water heater systems is the cost-effective way of generating hot water for your home and/or pool. These systems can be used in any climate and its cost to operate is only a fraction of the cost of heating your home using conventional heating systems.
How does it work ....
The 4 major components in a solar heating systems are Solar Collector, Solar Water Tank, Primary Water Tank, and Heat Pump.
In a closed loop solar heating systems, a propylene glycol liquid is used to protect against freezing. Sun warms the liquid in the solar collector on the roof or ground.
Using electric pump, liquid is pumped down to the solar tank where the heat exchanger is located which transferred the heat to the domestic water.
As the water is used, the hot water in the solar tank flows into conventional water heater. Since the water flowing in the tank is already preheated, the conventional water heater may or may not need to need to heat the water to supply the home.
A controller monitors the temperature of the liquid in the collectors and compare to the water temperature in the solar tank and continues the transfer process until the desire temperature is reached.
