Need help selecting your new system?

 

There are a number of factors to consider when selecting a new system including running costs, installation costs, environmental costs, number of people in your house and energy source whether it be solar, gas or electric. So here are a few figures to help you work out exactly what you need.

What is the minimum size system i should get?

 

1 PERSON - 50L Electric, 80L Electric (OFF PEAK), 90L Gas or 10L Continuous Flow

2 PERSON - 80L Electric, 125L Electric (OFF PEAK), 90L Gas or 14L Continuous Flow

3 PERSON - 125L Electric, 160L Electric (OFF PEAK), 130L Gas or 20L Continuous Flow

4 PERSON - 160L Electric, 250L Electric (OFF PEAK), 130L Gas or 24L Continuous Flow

5 PERSON - 250L Electric, 315L Electric (OFF PEAK), 160L Gas or 26L Continuous Flow

6 PERSON - 315L Electric, 400L Electric (OFF PEAK), 160L Gas or 2x20L Continuous Flow

 

The above quoted electric tank sizes are recommendations for peak power only, we recommend you add 40% capacity for off peak conditions.
