Product Description

feature:

Reliable, efficient, and fast heat transfer super metal heat pipe, no water in the pipe, frost resistance: -35°C, can be used in special cold regions.
Maximum stagnation temperature up to 250°C
Small heat capacity, output power within 5 seconds when the temperature is as high as 25°C
High efficiency, at least 10% higher than ordinary tubes
Simple plugin installation and maintenance.
Suitable for mains pressure water (up to 8 bar/116psi)
Stable solar conversion throughout the day (pipe passively tracks the sun)
The perfect solar collector for home solar water heater systems.
Suitable for large hot water projects such as swimming pools, schools, hotels...

The operation of solar thermal collectors is very simple.

Solar Absorption: Solar radiation is absorbed by the vacuum tube and converted into heat.
Solar heat transfer: Heat pipes conduct heat from inside the solar tubes to the headers.
Solar Storage: Water is circulated through headers by intermittent pumps. Each time the water circulates through the header, the temperature increases by 5-10oC / 9-18oF. Throughout the day, the water in the storage tank is gradually heated.
