About the Seven SS Stars 250 Liters Non-Pressurized Heat-Pipe Tube Solar Water Heater

The Seven SS Stars 250 Liters Non-Pressurized Heat-Pipe Tube Solar Water Heater is a solar-powered water heating system that uses heat-pipe vacuum tubes to collect and transfer heat from the sun into your water tank. It is non-pressurized, which means it works using gravity flow and does not need high-pressure pumps.

This model is built for households or businesses that use a lot of hot water every day. With 250 liters of capacity, it can provide enough hot water for bathing, washing, and cooking for a family of up to seven people. It is also a great choice for small hotels, schools, and clinics in sunny areas.

How It Works

1. Solar Collection – The heat-pipe tubes absorb sunlight and heat up quickly.

2. Heat Transfer – The heat is transferred to a copper rod inside the tube, which carries it to the water inside the tank.

3. Hot Water Storage – The insulated tank keeps the water hot for hours, even at night.

4. Gravity Flow – Since it is non-pressurized, the water flows naturally from the tank to your tap when you open it.

The system has no moving parts inside the tubes, making it very reliable and low-maintenance.
