Frequently Asked Questions

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

Solar should be seen as a supplement. A correctly sized system can provide 60%-70% of a household's hot water needs annually. The system can be automated to ensure hot water regardless of sunlight levels.

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

Depending on location and usage, costs can often be recouped in 4-5 years through reduced utility bills. Solar collectors are an affordable long-term investment for any household.

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

Yes. They can operate in temperatures as low as -30°C, though performance is reduced in extreme cold. Reliable heat output is still achieved in mild sub-zero conditions.

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

Solar tubes are strong but easily replaced if broken. The system can continue to operate with several broken tubes, though efficiency will decrease until replaced.

5. Will water be heated on a cloudy day?

Yes. While output is reduced on overcast days, the collector still provides heating. Automated gas or electric boosting maintains the required temperature when needed.

6. How do I protect the system during subzero temperatures?

Freeze protection is implemented using a controller. When temperatures drop below 5°C, the pump circulates water periodically to warm the collector. In extremely cold areas, a closed loop system may be used.
