❓ Frequently Asked Questions

Q1: 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 system is advised for days with little sunlight. The system can be automated to guarantee hot water regardless of sunlight levels.

Q2: How long will it take to recoup the investment?

Depending on your location and usage, costs can often be recouped in 4-5 years through reduced utility bills. These systems are highly affordable compared to traditional high-pressure heaters.

Q3: Can these solar collectors be used in cold conditions?

Yes, collectors can operate in temperatures as low as -30°C. While performance reduces in extreme cold, significant heat output is still achieved in mild sub-zero conditions.

Q4: What happens if one of the tubes is broken?

Tubes are very strong, but if one breaks, it can be replaced easily and inexpensively. The system can still operate with broken tubes, though efficiency will decrease.

Q5: Will water be heated on a cloudy day?

Yes. Heat output is reduced on overcast days, but the system still provides heating. On heavily clouded or rainy days, electric or gas boosting may be required to maintain desired temperatures.

Q6: How do I protect the system during subzero temperatures?

Freeze protection can be implemented via a controller. When temperatures drop below 5°C, the pump can periodically circulate water to warm the collector. In extremely cold regions, a closed-loop glycol mix may be used.
