1. System composition: flat panel solar water heater is composed of flat panel solar collector, water tank, control system, circulation pump and accessories. 2. Building integration: it can be installed flexibly on the slope roof or balcony, free from the location restriction, and does not occupy any space. It is the perfect combination of solar energy and construction. 3. Easy to operate: flat panel solar collector and water storage tank adopt the heat exchange of natural temperature cycle and forced circulation, auto supply water, temperature can be set freely. The operation is extremely simple. 1. System composition: flat panel solar water heater is composed of flat panel solar collector, water tank, control system, circulation pump and accessories. 2.
