Hongan solar.
The Hongan solar system consists of: an evacuated tube collector, a connectable water tank, an adjustable bracket and a heat exchanger.
The working principle of non-powered circulation instantaneous solar hot water system: the water in the vacuum tube begins to heat up after being exposed to solar radiation. Once the water in the tube warms up, its density decreases. and it flows naturally to the water tank.
Energy saving, environmental protection and significant economic benefits. Solar energy is an inexhaustible, environmentally friendly and pollution-free source of renewable energy. As long as there is sunshine, it will not operate normally.
