Energy saving tips on solar water heating system  
1.In the summer months when weather is continuously fine, shut off and isolate the backup heater (the existing heater using gas, electricity or oil), fully relying on the solar heater. This will further reduce the amount of energy which the backup heater uses to keep the tank water at the preset temperature. In this case, the water heater bill is ZERO! When you feel the solar water is not enough, just put in the backup heater (follow instructions given after installation). It takes only seconds by turning some valves.

2.Set the backup heater`s temperature to a lower grade. This will reduce tank heat loss while maximizing the use of solar water.

3.Do the hot water consuming jobs around noon time so that solar can produce another tank of hot water for your use in the evening.
