Sunnergy centralized heat supply project of solar energy hot water with the full glass vacuum tube/heat pipe vacuum tube/ flat plate is mainly suitable for industrial factory, mine, institution, school, hotel, restaurant, collective residential houses, swimming pool, greenhouse etc. Where large area of centralized heat supply system of solar energy is needed. Consisted of heat collector of heat pipe vacuum tube/full glass vacuum tube/flat plate, heat-preserved water tank, support, circulation pipe network, circulation pump and control system, it has working principle as follows: based on the set temperature, the forced circulation between the heat collector and the heat-preserved water tank is carried out by the circulation pump to transfer solar heat collected by the heat collector to the heat-preserved water tank continuously thus to warm up the water in the tank. When it is a fine day and sunlight is enough, large solar energy can be obtained to create more hot water in cloudy or rainy days or at night when sunlight is not enough, the auxiliary energy source system can be started automatically by the control system to warm up the water until the set temperature is arrived at, thus to realize all-weather hot water supply.
