Galvanized Steel Pre-Heated Solar Water Heater

Pre-Heated pressurized Solar Water Heater with High Efficiency

Pre-Heated pressurized Solar Water Heater

1. Pre-heat and pressurized solar water heater is a new product, it combine the advantages of Non-pressure solar water heater and Separated pressurized solar water heater together. Frankly speaking, the system is put a copper coil inside the Non-pressure solar water heater water tank, there is a pressure exists in the copper coil, the hot water inside the water tank is hot resource. This product improves the problems of traditional solar water heater as limited hot water volume, long heat time, few out water, the worse water quality. The "twice heat exchange" technology makes the high temperature, high efficiency and fast hot water circulation come true.

The vacuum tube collector absorbs heat energy to heat the water in the storage tank, when opening the valve, cold water flow through the inlet and then to the cooper coil, the hot water in the water tank do heat exchange via cooper coil with the cold water, when cold water flow through the copper coil, its temperature been rised gradully, finally the outlet water is hot water (the temperature maybe ≤ 5centigrade lower than the hot water in the water tank). The copper coil can bear the pressure from the running water.Product information
