Pre-heated copper coil solar water heaters

Pre-heated copper coil solar water heaters

1. Working principle

 Vacuum tube absorbs solar energy and transfer heat into main tank. And main tank is only for heat storage and copper coil is heat exchanger. When cold water goes through the long copper coil, it will absorb heat via copper and hot water will come out from outlet immediately. This will enable you to enjoy instant hot water.

5.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.
