Non Pressure solar Water Heater Working Principle
The vacuum tube absorbs the sun’s rays and turns it into heat energy, heating the water in the tubes. As the temperature of the water rises it becomes less dense, so the hot water in the tubes float into the tank, and the cold water in the tank travels down into the tubes. This natural cycle keeps repeating and the water in the tank gets hot. This unit will work below freezing temperatures as the glass tubes are sealed and heat can only enter and not escape from them. Non pressure system drains by gravity, unit must be placed at high place above supply line.
