If you use electricity for hot water production, you can save up to 90% of your hot water production costs on an annual basis. Water heating represents between 30- 50% of the total electrical load in a typical Hawaii home and the cost of electricity can exceed 20¢/kWh depending upon the island and generating efficiency of the local utility.
