Evacuated Tube Copper Coil Solar System

Evacuated Tube Pre-heated Solar System

1. Working principle

 The vacuum tube of the preheated solar water heater absorbs and converts solar energy into heat, then the heat is transferred to the main tank, and the copper coil inside the main tank is used as the heat exchanger. The main tank is designed to store the heat only, and the heater works with pressure inside the coils. When our preheating solar water heater works, the cold water flows through the long and hot copper coil, thus it will absorb the heat and at last the cold water is heated up, and hot water is supplied continuously, by the outlet pipe very soon. In addition, the hot water channel and cold water channel are separated from each other. Based on these, our product can supply fast and convenient hot water service for you.

6.ATTENTIONS:

1. Clearance of remains and sundries in water tank should be done ahead of installation in the purpose of avoiding walling up in or out vents, which may make  tank split up or deflated.

2. Do not load water when it is suuny. Better to load water at night or early in the morning expecially for the new unit. As the temperature of vacuum tube can reach 270°C at the highest. When water flowing at this time, vacuum tubes will be broken.

3.When loading water at a high water level, do not turn on the inlet valve openly but let water flow slowly to the tank, or the inner tank will be broken due to the expansion of high pressure.

4.It is inappropriate to load water at a low water level, which will result in hot water in the tank reflowing to water pipe.

5.Before having a bath, it is necessary to avoid scalding with hand to testing the temperature of water.

If electrical heater is installed, it should be cut off when you shower.
