1. What is the advantageof assistant tank non pressurized solar water heater ?

 

Non pressure solar water heater are installed on the roof and water will go down by gravity . the system not bear any pressure .so we call it non pressure system .

 

The solar assistant tank is like a automatic valve to control the cold water go into the main tank and keep the main tank full .

 

There is no need power to control the system ,so it save power .

 

Compared with pressure system , non pressure solar system is most economic .it is less expensive than any other types . it is most popular in warm weather countries .

  

2. working principleof assistant tank non pressurized solar water heater ?

 

From the below picture ,you will understand that how it works . there is a floating system inside the assistant tank , it will conrol the water inlet and outlet . the water inside the main tank is full all time and be heated by vacuum tubes .
