Integrated and Pressurized solar water heater provides main pressure preheating via a highly effective copper-coil heat exchange
Integrated and Pressurized solar water heater
Working principle:
The system can bear certain amount of pressure thus the running water can directly connect with the inlet, when opening the valve, cold water flow through the inlet and then to the cooper coil, the hot water inside the water tank play the role as hot resource and do heat exchange via cooper coil with the cold running water, during this process the cold running water been heated to hot water. (the temperature maybe ≤ 5 lower than the hot water in the water tank). All the storage tanks should be tested as tested pressure of 1.2 MPa (12bar) and the working pressure is 0.6MPa (6 bar). The daily efficiency is over or equal to 55%.
