Work Principle

Pre-Heated Compact Pressurized Copper Coil Solar Water Heater:

Vacuum tubes absorb heat energy to heat the water in the storage tank.
A 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

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

Solar should be seen as a supplement. While it can provide 60%-70% of a household's hot water needs annually, a backup gas or electric system is recommended for days with little sunlight.

How long will it take to recoup my investment?

Depending on your location and usage, savings on electricity or gas can allow you to recoup the full cost within 4-5 years. You will make considerable savings over the life of the heater.

Can these solar collectors be used in cold conditions?

Yes. Collectors can operate in temperatures as low as -30°C, though efficiency is reduced in extreme conditions. Good heat output is still achieved in mild sub-zero weather.

What happens if one of the tubes is broken?

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

Will water be heated on a cloudy day?

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

Can I use a solar collector with my existing hot water system?

Normally yes. Simple retrofit valves can allow connection to your existing inlet. If the tank cannot accept input directly, an additional storage tank can pre-heat the water.
