1. Do you live in a sunny enviroment?

2. How much water do you use?

3. Is your present system compatible with a solar water heatin system?

The real question here is do you have room for an additional water tank? If not and your current tank is not built with solar power in mind then either a solar system is not suitable for you or you will need to replace your current tank.

4. Is your boiler compatible?

Most boilers are suited to solar additions but if it is a combi boiler then the chances are then it is not.

How much can you save

Depending on the amount of sunshine you get and how much water you use, the average household can save between $80 - $120 a year using a solar system. Of course this i ignoring the various government schemes which can pay you for heating your own water.
