## Water Heating Cost Formula

The following formula is used to calculate the Water Heating Cost.

**WHC = E * CE**

- Where WHC is the Water Heating Cost ($)
- E is the total energy required to heat the water (kWh)
- CE is the cost of the energy ($/kWh)

## How to Calculate Water Heating Cost?

The following example problems outline how to calculate Water Heating Cost.

Example Problem #1:

- First, determine the total energy required to heat the water (kWh). The total energy required to heat the water (kWh) is given as 500.
- Next, determine the cost of the energy ($/kWh). The cost of the energy ($/kWh) is provided as 2.5.
- Finally, calculate the Water Heating Cost using the equation above:

WHC = E * CE

The values given above are inserted into the equation below:

WHC = 500 * 2.5 = 1250 ($)

Example Problem #2:** **

The variables needed for this problem are provided below:

total energy required to heat the water (kWh) = 700

cost of the energy $/(kWh) = .3

Entering these values and solving gives:

WHC = E * CE = 210 ($)
