If we assume that approximately 35% of your total energy bill (say 2000 kWh per qtr for a 4 person home) is used on hot water at present and that you are pay approximately 26c/kWh for your electricity. (Approximately 13c/kWh if use off-peak electricity to heat your hot water).

It can be expected that you will be able to save approximately 68% of your hot water bill by installing an heat pump Solar Hot Water System.

Saving per Qtr = 2000 x 0.35 x 0.68 x 0.26 = $123.76.
Approx Saving per year = $495.04

Payback period = Capital Cost/Yearly Saving
= ($3,457)/$495.04
= 6.98 years
Return on investment = Yearly Saving/Capital Cost x 100
= $495.04/($3,457) x 100
= 14.3%
