Try our simple-to-use Water Heating calculator to better understand your water heating costs and options. This tool calculates your Btu requirements and the estimated operating costs to heat water on an off-peak electric rate.

To use this calculator, you'll need to know:

• The type of fuel you currently use.
• The price of that fuel.

If you don't heat your home with electricity, our calculator applies our Controlled Service Water Heating Rate for your state. If you do heat your home with electricity, it applies our small Dual Fuel Rate for your state. 

Rate calculations include rates, adjustments, and riders effective October 2022.
