High quality separate pressurized solar water heater

Specifications

Features:
1. 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 pressurized solar water heater collector and the water tank 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 used
5. Can be combined with gas or electric heater
6. Max. Pressure: 12bar; Operating Pressure: 6 bar
7. It can be used for other function, such as warming

Split pressurized solar water heater working principle:  

1. The collector absorbs solar energy and transmits it to the water tank through circulation
2. When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically
3. The circulation pump makes heat-conducting liquid circulate automatically
4. 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 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.
