Solar thermal central water heating system is split solar system, which means the solar collectors are connected with the water storage tank through pipeline. According to the difference between the water temperature of the solar collectors and the water temperature of the water tank, the circulation pump is used to make the water of the solar collectors and the water of the water tank conduct forced heat exchange. That is, when the water temperature of the solar collectors is 5-10 degrees higher than that of the water tank, the circulation pump works to pump the water from the water tank to the bottom of the solar collector, and the hot water on the upper part of the collector is pushed into the water tank; When the hot water of the collector is balanced with the water temperature of the water tank, the circulation pump stops working, so as to continuously improve the water temperature of the water tank. This method has high thermal efficiency and fast temperature rise.
Some users use the constant temperature water outlet type, that is, when the water temperature of the solar collector is higher than set value 1, supply tap water to the collector, push the hot water of the collector into the water tank, and stop water supply when the water temperature of the solar collector is lower than set value 2. This method has the advantage of low cost, but the set value should be adjusted according to different seasons.
About SolarShine’s solar thermal central hot water system:
Solarshine’s Solar thermal central water heating system is combined with high efficiency solar collector, hot water storage tank, pumps and assistant parts such as pipes, valves etc. Through our professional control system, we can preferentially use the heat obtained by solar radiation. In sunny days, the system can meet the demand of hot water generated by solar energy, the back-up electric heating element is a necessary auxiliary heat source. When the hot water produced by solar energy fails to meet the use requirements in continuous rainy days or a small part of the hot water needs to be kept constant temperature at night, the electric heater starts heating automatically.
Standard Components of the system:
1. Solar collectors
2. Hot water storage tank
3. Solar Circulation pump
4. Cold water filling valve
5. Back-up electric heater element
6. Controller and power station
7. All the necessary fittings, valves and pipe line
8. Other optional parts need to be purchased separately according to the actual situations (such as quantity of shower, building floors, etc)
8-1:Hot water booster pump (use to increase pressure of hot water supply to shower and taps)
8-2:Water return controller system (used to maintain a certain hot water temperature of hot water pipeline and make sure fast indoor hot water supply)
