Working Principle

Mechanism of Pre-Heated Compact Pressurized Copper Coil Solar Water Heater:

Vacuum tube absorbs heat energy to heat the water in the storage tank.
Copper coil is installed in the water tank as the heat exchanger.
The water tank acts as a thermal source.
When water flows into the copper coil, it absorbs heat from the water in the tank.

Frequently Asked Questions

1. Is solar water heating a viable alternative to gas or electricity?

Solar should be seen as a supplement. While it cannot totally replace gas or electric heating on low-sunlight days, a correctly sized system can provide 60%-70% of a household's hot water needs annually.

2. How long will it take to recoup my investment?

Depending on your location and usage, the cost may be recouped as quickly as 4-5 years through reduced utility bills. Solar hot water heaters offer considerable savings over their entire lifespan.

3. Can solar collectors be used in cold conditions?

Yes. These collectors can operate in temperatures as low as -30°C, though performance is naturally reduced in extreme cold. Good heat output is still maintained in mild sub-zero conditions.

4. What happens if one of the tubes is broken?

Tubes are durable but easily replaceable if damaged. The system can still operate with several broken tubes, though efficiency will decrease, so immediate replacement is recommended.

5. Will water be heated on a cloudy day?

Yes. Although output is reduced on overcast days, the collector still provides heating. Automated gas or electric boosting can maintain the required temperature during heavy rain or thick clouds.

6. How is the system protected during subzero temperatures?

The easiest method is using a controller with a low-temperature setting. When the manifold drops below 5°C, the pump circulates water from the bottom of the tank to warm the collector. In extremely cold regions, a closed-loop glycol mix may be used.
