solar water heaters .Competitive price, good quality .Keymark,SRCC .5 years warranty .after sales solution Solar water heatersModel: FD-SP2-300L Solar water heaters features1. The upright tank can make the water temperature to a high level. It can hot the water instantly. 2. The tank inside the building, the hot water loses less energy than the normal one 3. The solar collector and the tank of solar water heater is separated, that makes the system combine with the building perfectly, which will reduce the sightseeing for the building and environment around 4. Back up with electric heater so that in the day without sunshine hot water can also be used5. Can be combined with gas or electric heater 6. Max. Pressure: 12bar; Operating Pressure: 6 bar7. It can be used for other function, such as warming Solar water heaters working principle1. The solar collector absorbs solar energy and transmits it to the solar water heater tank through circulation 2. When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically3. The circulation pump makes heat-conducting liquid circulate automatically4. The heat-conducting liquid transfers heat to water by lower heat exchanger in the water tank. 5. When the temperature difference between solar collector and heat pipe solar water heaters tank doesn't reach the set value, the circulation pump will be shut automatically 6. In case the temperature of the water tank does not reach Tmax, Electric Heating Element will start to work automatically Solar water heaters working station component1. Operating screen 2. Manometer 3. Pump speed adjust switches 4. Temperature difference circulation pump 5. Flow rate indicator 6. Return circuit connector 7. Safety valve 8. Expansion vessel connector9. Return circuit connector 10. Wall mounting 11. Expansion vessel:8L 12. Pressure resistance: 10 bar pressure for expansion vessel Solar water heaters specification
