What Is the Seven SS Stars 350 Liters Non-Pressurized Heat-Pipe tube Solar Water Heater?

The Seven SS Stars 350 Liters Non-Pressurized Heat-Pipe tube Solar Water Heater is a solar-powered water heating system that uses sunlight to heat water. Instead of using electricity or gas, it collects solar energy through glass tubes called heat pipes. This heat is transferred into a water tank for storage. With a large 350-liter capacity, it can serve a family of 6–8 people or even small commercial setups like guest houses and schools.

The “non-pressurized” part means that water flows in using gravity or a small pump, rather than high-pressure mains water. This makes the design simpler, less expensive, and easier to maintain.

How the Heat-Pipe Technology Works

Heat-pipe solar water heaters use a set of sealed copper tubes filled with a special liquid. Here’s how it works:

1. Sunlight Hits the Tube – The glass vacuum tubes trap sunlight and convert it into heat.

2. Liquid in Heat Pipe Warms Up – The liquid inside the copper pipe evaporates as it heats up.

3. Heat Transfers to Water Tank – The hot vapor travels up to a condenser inside the tank, releasing heat to the water.

4. Liquid Returns to the Bottom – The vapor cools down and returns to liquid form, ready to repeat the cycle.

This method is faster and works better in cooler or cloudy weather compared to older direct-flow systems.

Types of Solar Water Heaters

When choosing a solar water heater, you’ll find several types. Here’s how they compare:
