100L-350L. Solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's use of hot water in life and production . Solar water heaters can store 100 to 350 liters of water. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share.
If it is a 58*1800 tube, theoretically a tube can produce 10 liters of water, 36*10=360 liters of water, if it is intended for a domestic use, 50 to 60 liters of water per person. It's enough and can wash 6-7 people. If shared, it will be calculated based on 100 liters of water per person (all wasted!), and only three to four people canhave been washed.
