Solar water heater. No controller and no pump. Making and installing

Self-made, cheap and simple solar water heater. Suitable for off grid living, no electricity required. No controller and no pump. Made from polycarbonate and CPVC pipes. For many years we used a solar collector for water heating in our homestead. It was made of tin radiators and covered with double glazing. Over a long period of time, the wooden frame rotted, the glass broke, and the radiator was punctured. We are making and installing a new solar collector for water heating. We will have free hot water in the house. Watch, relax and enjoy life. Homesteading, slow living, country life
