1. Is a Solar Hot Water System a good investment for me?
The potential savings on water heating bills are affected mostly by the type of fuel you are using to heat water and the number of people in your home. If you are heating hot water for two or more people and you are using electricity to do so, then you owe it to yourself to look at solar water system, it could be a great investment for you.
2. Is a Solar Water System safe?
Yes. The majority of solar collector's components are stainless steel, aluminum,
polyurethane and free from electricity, therefore evacuated tube solar collectors eliminate fire risk and dangers related to electricity.
3. Can a Solar Water System be installed anywhere?
Yes, the JB and JR series can be installed on a flat and sloped roof. The SLL and SLU series (solar water system with remote storage tank) can be installed on a flat, sloped roof, facade and open ground.
4. Does a Solar Water System generate hot water all seasons of the year?
The solar water system generates hot water on:
- Clear sunny day: Maximum
- Partially cloudy day: Moderate
- Rainy or heavily overcast day: Nil
Average 300 days in a year you will get hot water from you soar water system.
5. What about the bad solar radiation days?
For the JB and JR series solar water heater, has the option of installing an auxiliary electric element as a backup.
For the SLL and SLU series solar water heater, the back-up heating system is up to you, it can be an electric element or the boiler run on oil, gas, wood or even coal. No matter what your choice is, it must be well combined with the solar storage tank.
6. Can the Solar Water System operate in freezing areas?
Yes. The JB and SLL series solar water heater can be used in areas with temperature as low as -30℃. In continuous cloudy days, the electric heater should be used to keep the water hot/warm. The JR series with heat pipes and SLU series with U tubes operate normally in -40℃.
7. Does the Solar Water System generate high temperature water?
Yes, the system can be designed to give you an average output temperature as high as
60-85℃. If you consider that when having a shower the water temperature is usually around 32-43℃. Scalding can occur at 54℃, therefore the temperature output is more than sufficient. In fact in some countries you may have to fit a thermostatic tempering valve to your house plumbing to conform to government health and safety regulations. This valve will temper water down to between 43 and 50℃.
