Q: If it rains do I still have hot water?
A: Yes – the tank has an electric element and thermostat. You are guaranteed hot water up to thermostat setting.
Q: If the electric element is on – how much electricity can I save?
A: If the Solar Water Heater is correctly sized for your family. You will save 80% of your electric geyser costs that you are now spending. This 80% is an average for the full year.
Q: If I spend all that money, when will it pay me back?
A: Most families recoup their investment between 3 – 8 years depending on hot water usage.
Q: After 5 years the system breaks and I have to replace it. What is the use?
A: Chromagen is designed to last up to 20 years, if it is serviced regularly and the anode is replaced. You will save approx 15 times what you invested..
Q: Why must the tank be on the roof?
A: It is the most efficient way of collecting heat and storing it. The tank MUST be as close as possible to the absorber panels. If you split the system – it will lose efficiency.
Q: How long does it take to install?
A: Between 3-8 hours depending on how difficult the installation is.
Q: Why can I not re-use my old geyser?
A: Your old geyser is designed for electrical heating and is not solar compatible. If you adapt an old geyser to solar heating you will end up with a hybrid solution that is very inefficient.
Q: How do I determine if my roof is suitable for a SWH system, i.e. below 30 deg pitch.
A:Either find a protractor and measure the pitch on the rafter, OR - can you walk on the roof with out sliding off? This will be about 30 deg or lower!
