Feature

1.A copper coil is installed inside the tank as the heat exchanger.

2.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.

3.Use at any time.It adopts advanced desigh idea and integrated with high efficiency preheated  patent

technique,so it can warm the cold water rapidly when it flows through special pipe.It can overcome the short of traditional solar water heater ,such as slow heating,long  waiting time.

4.More capacity.We adopt special exchanging heat mode ,it avoids mixed effect ,so cold water can be heated at any moment.

5.Easy operation.It can supply water automatically ,u can take it easy and enjoy good time.

 

The water of the heat preservation water tank is just decalescence, heat accumulation and thermolysis the water of the water tank is invariableness. The vacuum tube collector absorb the heat energy to heat the water in heat storage tank, when using the hot water, the cold water flows through the inlet, the copper coil absorb the heat then transfer into the cold water ,so that the temperature rise up ceaseless, for the original features of the copper coil, the water temperature of the outlet is close to the water temperature of the water tank(≤3), so the high pressure of the cold water into the copper coil and absorb the temperature, at last the water can be used.
Pre-heated pressured solar collectors provides mains pressure pre-heating via a high efficiency copper coil heat exchanger located within the solar collector tank. The way in which the Mains Pressure solar collector heats water is the same as the Non pressure solar collector.. Rather than using the water in the tank directly, as the Non pressure does, the type uses a 4560 copper coil. Heat exchanger inside the tank which provides more than 1.2m2 of heat transfer area. When water flows though the coil it absorbs heat from the water inside the solar collector tank. The solar collector tank is therefore a thermal store. One advantage of this system is that almost no water is introduced into the tank (apart from occasional topping up),so corrosion and scale buildup are almost totally eliminated. Tanks are designed for low to medium pressure applications using gravity feed tank or pressure reduction valve. Direct connection to mains pressure water supply is not permitted. Please check your local building/plumbing regulations regarding the installation of water tanks.
