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?
