Solar water heater working principle:
1. 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 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 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
