integrative pre-heated copper coil pressure solar water heater

integrative pre-heated copper coil pressure solar water heater

Working principle:

The water in water tank is for heat preservation and circulation. The vacuum tube collector absorbs sunshine to heat the water in water tank, when using the hot water, the cold water flows through the inlet, the copper coil absorbs heat then transfer to the cold water, so that temperature rise up ceaselessly, due to the original feature of the copper coil, the water temperature of the outlet is close to the water temperature of water tank(difference within 3 degree centigrade). Therefore, cold water flow via copper coil and absorbs much heat, when water flow past outlet, the temperature is usually hot enough to use.

Feature:

1. It can withstand pressure of tap water when it works, and copper coil in tank bear pressure.

2. Storage tank is used to heat water flowing through copper coil, water absorbs much heat when flowing through the copper coil, hot water is available immediately when you need.

3. High quality SUS304-2B stainless steel for water tank, processed by argon arc welding technique, under strict quality control system, tank will never rust and leak.

4. High borosilicate all glass vacuum tube has selective absorbing surface, absorptivity above 0.93 and emissivity below 0.05, it enables vacuum tubes to have good absorb and transmit performance.

5. Relevant accessories are optional instead of compulsory, client can choose some or none according to actual need. Assistant tank is recommended for this series.

6. It can produce hot water with constant temperature.

7. It's indirect solar system, so water quality is superior, much cleaner than direct solar system.

8. 24 hours water supply on condition that pipeline is working.
