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 guarantee hot water regardless of sunlight levels using gas or electric backups.

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

Depending on location and usage, the full cost of purchase can often be recouped within 4-5 years through reduced energy bills.

3. Can solar collectors be used in cold conditions?

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

4. Will water be heated on a cloudy day?

Yes. While output is reduced on overcast days, the collector still provides heating. Automated backups ensure you don't run out of hot water during heavy rain.

5. 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 at reduced efficiency until they are replaced.

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

A controller with a low-temperature setting can periodically circulate water to prevent freezing. In extremely cold regions, a closed-loop system using a glycol/water mix is recommended.
