1. Non pressure solar water heater is open loop system, inner tank basically is 0.28~1.0mm thickness, majority are 0.31/0.38/0.45mm thickness, 

    while, high pressure solar water is closed loop solar water heater, with inner tank range from 1.0mm to 1.5mm thickness. 

 

2. Non pressure solar water heater bear lower pressure, Max. 0.05MPA, while, high pressure solar water heater can bear 0.7Mpa, 

 

3. There are copper heat pipe inside each vacuum tubes, work as heat exchanger, thus, there is NO water inside each vacuum tubes, even if one of the vacuum tube broke down, the system will keep on working, 

    while, for non pressure solar water heater, there is water inside each tubes, if one vacuum tube beak down, all the water will leak out, system will not work. 

 

4. Due to copper heat pipe with superior anti-freezing performance, it can well work under - 35~ -40 degree ambient, thus, no need to worry about frozen problem in winter, 

    while, for non pressure solar water heater, due to water will fill inside each vacuum tubes, when temperature is lower than -5 degree, tube will burst due to frozen.

 

5. Compact heat pipe is closed loop system, with less energy loss, and copper heat pipe with high efficiency, thus, compact high pressure is more efficiency than non pressure solar water heater 

6. Due to inner tank of high pressure system is much thicker and each vacuum tubes are well configured with copper heat pipe, thus, lead to high cost,  

    compared with high pressure solar water heater, non pressure solar system is affordable & bankable. 

 

In a nutshell,

world widely, Non Pressure Solar Water Heater :cheaper, cost effective, easy for maintenance.

Non pressure is the best selling system, due to it is simple & easy for maintenance,cost effective in price, it enjoy a great market,

for region with good purchasing power and harsh & long winter region, high pressure solar system is the premium choice....
