Easiest savings

This graph says it all. Households can save up to 80% of their water heating costs and in some cases even more. 

In a typical 3/4 family household that uses 80% of its 150L geyser water volume heated to 65DegC per day at an average tariff of R4/kWh and an annual escalation of 11% per year, the family using their old electric geyser can spend over R9154 per year just on water heating.
