The energy saving varies from household to household. There are many variables to consider when counting all the costs and the total saving you can gain on using an electric water heater. But no matter how you look at it you’ll save on your energy bill.
We’ll use a simple illustration to show the cost of using an electric water heater. If you run your unit for three hours a day at 5500W that equals 16500W per day. If on the average, you pay 6.9 cents per KwH that would give you an average of $1.15 per day. Compare that amount to what you’re paying currently and you’ll be able to calculate your total savings per month.
