Working Principle

Pre-Heated Compact Pressurized Copper Coil Mechanism:

Vacuum tubes absorb heat energy to heat the water in the storage tank.
A copper coil is installed in the water tank as a high-efficiency heat exchanger.
The water tank acts as a stable thermal source.
When water flows into the copper coil, it absorbs heat from the water in the tank, 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. The system can be automated to ensure hot water availability 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 electricity or gas bills.

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

Yes, these collectors can operate in temperatures as low as -30°C, though performance is naturally higher in milder 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 at reduced efficiency.

5. Will water be heated on a cloudy day?

Yes. While output is reduced on overcast days, the system still provides heating. Electric or gas boosting handles requirements on heavily raining days.

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

Normally yes. Retrofit valves allow connection to existing cold water inlets or a pre-heating tank can be added to the circuit.
