Compact Pressurized Solar water heater with Heat Pipe

Model: STH-150L, STH-200L, STH-300L

New Integrated Pressurized solar water heater: STH with 316L for blind tube
For our compact pressurized model STH we have special design: We use 316L material for blind tube instead of copper caecus tube, because for copper blind pipe after some period with the high temperature and high pressure, or in the water quality inferiority area, it will face corrosion and will happen blind pipe perforation phenomenon or blind pipe leakage. This new blind pipe is composed of 0.9 mm stainless steel 316L stamping with the red copper gasket.


1. Slope roof and flat roof avaliable.
2. Looks more beautiful.
3. Inlet and Outlet hole at the back of the tank, any angel of roof is suitable.
4. Electric heater on the tank cover(side)
5. SUS316L stainless steel heat pipe condenser
