Solar Water Heater - Hot Water day and night, 365 days
Hot water is a vital necessity that, however, can be expensive to obtain using typical water heating methods. Turn to the sun for your household or commercial water needs, and you’ll get quick hot water all year at virtually no expense.
Whether you manage a house, office, hotel, hospital, or industrial facility, having rapid and simple access to hot water is not only required, but critical to your operations. Relying on boiler technology is not a cost-effective long-term solution, since it incurs high electricity expenses month after month, year after year.
Every business and family can benefit from the sun’s plentiful power via a solar water heating system, which provides clean and renewable energy at reasonable prices, thereby balancing commercial and environmental impacts.
Flat Plate Collectors
The solar water heating system includes a solar collector made of aluminum with a toughened glass sheet on top. A copper absorber plate, selectively coated for improved performance, serves as the collector’s heart. This plate absorbs the maximum amount of heat from the sun and transfers it to the water. The collector box is properly insulated to avoid heat loss.
Evacuated Tube Collector
An evacuated tube serves as an absorber in this sort of business or home solar water heater. Each evacuated tube is made up of two glass tubes with a vacuum in between, which serves as an effective insulator. The incident solar energy strikes the inner tube, which has a dark absorbing covering, after passing through the outer transparent tube. It absorbs thermal energy and transfers it to the cool water running through the tube.
How does the water stay warm?
Thermosyphon
In this system, the water in the storage tank circulates constantly through the collectors, relying only on the natural flow of water caused by the difference in specific gravity between hot and cold water. It does not require power and is a simple, maintenance-free solar water heating system. However, in this method, the temperature cannot be controlled, and as hot water is drained from the tank, it is replenished with fresh cold water, resulting in some mixing.
Forced Flow
The flow in this system is controlled by a control panel and pump. Cold water is pumped through the collectors and allowed to remain until the desired temperature is obtained. Only then does the pump turn on, pushing the hot water into the storage tank. The entire system is automated, thus it must be powered by electricity. In this method, the temperature may be adjusted, and the water in the storage tank is always at the specified temperature.
