240L radius of the tank of fresh water solar water heater advantages will be quality products, attentive service, fresh water solar energy into every family. Allow people to experience the energy-saving, green living healthy and comfortable. The Solatube Sunshine Energy Technology Co., Ltd., a little contribution for your healthy living, but also for the development of China's solar energy industry to contribute their heat. Advantages: fresh water solar water heater the Solatube sunlight professional solar system design, http://www.bjsola.com pressure water, without adding booster pumps, hot water pressure from the cold water pressure, hot and cold pressure match, surging heat temperature control; water freely. RHES-reverse heat exchangers, thermal storage tank HTM heating coil heat exchanger in the cold water, this process does not need the help of pumps and other external forces, and timely access to hot water without any pollution, water quality, and the pressure and similar municipal cold water. The Solatube sunlight professional solar system design, http://www.bjsola.com 20 seconds fast heat transfer technology, municipal cold water supply conditions, cold water flows through the stainless steel corrugated tube heat exchanger 20 seconds into hot water quickly, and the the temperature difference between the temperature and heat medium 2-5 °, nitrite-free and pathogen group, fresh water drinkable. Does not require artificial water, not to string water, worry and effort. The closed system can be matched with any conventional heat sources (electricity, gas). Vacuum tube, water tank does not scale, to facilitate future maintenance. The appearance of new, different. Square round, solar water tank was installed on the roof relative to the circular tank better good fusion with the building. Solar water heat exchanger coil imported SUS304 stainless steel.
