【 Introduce 】
Working principle:
The vacuum tubes with heat pipe absorb solar energy and transfer heat into the tank.But the water in the tank is not to use,the tank just as a storage tank.One copper coil is installedin the tank as the heat exchanger. When water flows into the copper coil,it absorbs the heat of the water in tank via copper coil.

◆ A copper coil is installed inside the tank as the heat exchanger;
◆When water flows into the copper coil, it absorbs heat from the water in the tank, therefore; the water tank is just a heat storage;
◆Can be used at any time to warm the cold water. It can overcome the shortcoming of traditional solar water heater, such as slow heating rate, long waiting time.
◆High efficiency: A special heat exchanging mode is adopted to avoid mixed effect, so cold water can be heated at any moment.
◆Water pressure is same as tap water; it can be connected directly to city tap water system.
◆Green and economical. No pollution in working, no cost for hot water.
◆Easy operation. Automatic water supply, you can take it easy and enjoy good time.
◆Fashionable. The appearance is nice and attractive and can fit into the surroundings properly.
