1. Materials: box (preferably an iron box), small box (must be metal), foam, reflective plate (aluminum from a cigarette box, mirror, old CD...), adhesive tape, black paint, cellophane . .
2. Boxes and small cans should be painted black (this can absorb more heat). Dig a hole in the foam (also painted black) that can be inserted vertically into 3/5 of the small can. ((to retain heat), 2/5 are exposed outside to receive sunlight. Put the moss and the small box into the box, seal it with cellophane and make a support frame behind the box so that the box can stand tilted towards the sun. Behind the box, above, install reflectors on the left and right sides. The lower reflector can be placed directly on the ground in front of the box. the better the reflected light).box or the small box, so that the box and the box can absorb more heat. A simple solar water heater is made.
1. To prepare the materials, you must first prepare the following materials: solar panels, PVC pipes, tees, elbows, internal tooth joints, glue, insulating pipes, paint, electronic thermometers, old iron sheets, and plastic foam, old sponge, etc.
2. First find solid, good quality wood and simply make a 2.1X1.2m frame. Then transform the T-pipe into a hot exhaust pipe of the same type as the water heater device. Then pour foam over the frame and paint the foam and the old iron sheet black.
3. Connect the shelf made of solar panels to the thermal tube. Note that the pipe must be installed with an insulating tube. If you have an electronic thermometer, you can install an electronic thermometer to make it easier to detectaction. of the water temperature.
4. Install the vertical post behind the support and cardboard. The height and inclination of this vertical pole can be adjusted as desired. Then the glass tube is filled with water and the glass tube is first sealed and then placed on the rack. Then adjust the pole, observe the direct angle of the sun and adjust the pole to the corresponding height. The larger the area exposed to the sun, the better.
5. When adjusting the concave arc of the pole, you should do it on the roof of a building exposed to the sun or in a high place. The reflection of the sun focuses on the glass tube. better effect. Then simply attach the bracket.
6. After a while, the homemade solar water heater can use the principle of cold water flowing and hot water floating to check the water temperature. Then wait a while, then check the amount of hot water obtained. You can equalFill the homemade solar water heater with an appropriate amount of water depending on the weather of the day and connect the pipe from the water outlet to the place where hot water is needed.
