Non-pressurized compact solar water heater

Working principle

This compact solar water heater uses tubes with water inside it. The tubes get solar energy and heats the water in the tubes. When water to be heated, the hot water will go up while the cold water flows to the tubes to get solar energy. It is a compact circulation on its own without giving pressure. It is better to have an assistant tank above the water tank. When the hot water in the tank shorten, it will supply automatically, or the compact system will be parched.
