Water Heater Operating Costs

The chart below lists the estimated cost to operate a water heater based on the type of water heater that it is.

What is the best deal today?
If your current heater is electric
If you have an electric water heater that needs replacing, an electric heat pump water heater is your best value for the long run. You will save $160 per year with an electric heat pump water heater versus a standard electric water heater. If you don't mind the upfront cost, a solar water heater is an equally good value.
If your current heater is natural gas
If you currently have a natural gas water heater, then replacing it with the same type is a good move. If you would like to be self sustaining and contribute less to your utility company, then a Solar or a Heat Pump Water Heater is also a good value.
