Working Principle

How the Pre-Heated Compact Pressurized Copper Coil Works:

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 through the copper coil, it absorbs heat from the tank water, providing instant hot water.

Frequently Asked Questions

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

Solar is a supplement that can provide 60%-70% of a household's hot water needs annually. It is often automated to guarantee hot water regardless of sunlight levels.

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

Depending on location and usage, the cost may be recouped as quickly as 4-5 years through reduced energy bills.

3. Can the solar collectors be used in cold conditions?

Yes, they can operate in temperatures as low as -30°C, though performance is naturally reduced in extreme cold compared to mild conditions.

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

Tubes are durable but easily replaceable if damaged. The system can continue to operate even with a broken tube, though efficiency will decrease.

5. Will water be heated on a cloudy day?

Yes. While heat output is lower on overcast days, the system still provides heating. Automated backup heating can maintain desired temperatures when needed.

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

Normally yes. Retrofit valves can often connect solar to your existing cold water inlet or a pre-heat storage tank can be installed.
