1. What is a Water Heater Savings Calculator?

Definition: This calculator determines the savings achieved by using an energy-efficient water heater compared to a conventional one.

Purpose: It helps homeowners and businesses evaluate the financial benefits of upgrading to more efficient water heating systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Savings \) — Amount saved by using efficient water heater (currency)
• \( Conventional\ Cost \) — Operating cost of conventional water heater
• \( Efficient\ Cost \) — Operating cost of efficient water heater

Explanation: The difference between the two operating costs shows your potential savings.

3. Importance of Water Heater Savings Calculation

Details: Calculating savings helps justify the investment in energy-efficient appliances and reduces long-term utility expenses.

4. Using the Calculator

Tips: Enter the annual operating cost of your current water heater and the estimated cost of the efficient model. Both values must be ≥ 0.
