Domestic heat pipe solar water heater

Specifications

Heat pipe solar water heater  working principle

Heat pipe has some medium inside, When solar vacuum tube absorb heat energy from sun, then transmit it to heat pipe , the liquid medium of the bottom of heat pipe become vapour, then rise up to the top, cooled by cold water then 

go down to the bottom of heat pipe,This is circulation of solar heat pipe collector. This complete system is connected 

by pipe (copper pipe). There are two temperature sensors in solar heat pipe collector and water tank, For example, We set the 

temperature difference is 10 degree, when the water temperature rise, and the temperature difference between solar 

heat pipe collector and water tank exceed the set value, The controller inside solar working station will start the circulation pump, the cold water will cool the solar heat pipe collector, and heat the water inside water tank by exchanger inside water tank, when the temperature difference is down under the set value, The controller will stop the circulation. It just is circulation process. Via one day working, the water temperature of water tank can arrive in 50~95 degree.

Specification:

1. Water tank inner shell: 1.2~1..8mm SUS304-2B (food grade stainless steel).
2. Water tank outer shell: 0.4mm colored steel or 0.4mm SUS304-2B .
3. Stand: galvanized steel with painting, or aluminium alloy, or stainless steel.
4. Water tank heat insulation layer: 50~60 mm polyurethane foam.
5. Stand angle: 15 degree, 20 degree, 25 degree, 30 degree, 38 degree, 45 degree for flat roof 

 Characteristics

This model works with high pressure, so it can be connected with city water directly. With the heat pipe in the vacuum tube, therefore no water in the tube, each tube can work alone, so the solar collector can work even one tube is broken.

1. Highly efficient absorber of high performance with daily average efficiency over 50%
2. Start up quickly, the water is heated rapidly by heat pipe which will transfer the heat energy into the tank
3. Withstand pressure of 6 bar, more comfortable to use
4. Simple structure, easy to assembly and install
5. Can be used all year even in the cold climate area
6. Long service life, can be used over 15 years

Warranty :  
5 years' International responsibility for free repairing or exchange due to original quality problem      
Remark :      
a) We offer  2% vacuum tubes for free for exchange in case several shattered vacuum tubes during transit      
b) About the following accessories, if you need, we can offer it to you,  But should charge it.
