Color Steel Non Pressure 240L Evacuated Tube Solar Water Heater System

Description:

Accessories: Stainless bolts & nuts, water-proof silicon rubber, anti-aging dust-proof rubber seal, plastic pipe holder and ventilating cap to ensure their lives as long as other parts of the system

Optional Devices

1.Assistant tank, to automatically feed tap water into storage tank to keep it sufficient always

2.Electrical heater, as an auxiliary heating element in case of raining or snowing days so as to ensure a continuous hot water supply

3.Intelligent controller, automatically controls water refill and start up of auxiliary heating device, more intelligent operation

How non-pressurized solar water heater works
1. Non-pressurized solar water heater of all glass evacuated tube collector integrated with storage tank, are ideal for use in houses and other applications where cheap, reliable hot water supply is required. They are simple, economic and practical.
2. As the specific gravities of hot water and cold water are different, cold water goes downward and hot water goes upward.
3. When cold water in evacuated tubes is heated, it becaomes lighter and goes to the water tank, while cold water in the tank goes down to the evacuated tubes
4. Through this circulation, the cold water in the water tank will be gradually heated.

Applications:

Domestic hot water for shower, washing

Competitive Advantage:

1. Advanced welding technology to prevent any leaking of tank

2. Special chemical layer between inner tank and outer tank to make sure the density of foam the same everywhere

3.Non-pressurized solar water heater is such kind of a most economical system with high efficiency at the same time. It works depending on the gravity of water, so it's much better to be installed on the slope or flat roof as top as possible to get enough hydraulic pressure.

4.A simple assistant tank can be equipped for tap water refill automatically or with an intelligent controller to control the start up of auxiliary heating device at the same time.
