1. What is a Tankless Water Heater Savings Calculator?

Definition: This calculator estimates the potential savings when switching from a conventional water heater to a tankless system.

Purpose: It helps homeowners and businesses evaluate the financial benefits of upgrading to a tankless water heater.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Savings \) — Annual savings in currency
• \( Conventional\ Energy \) — Energy used by conventional heater (kWh)
• \( Tankless\ Energy \) — Energy used by tankless heater (kWh)
• \( Price \) — Cost of energy (currency/kWh)

Explanation: The difference in energy consumption is multiplied by the energy price to determine annual savings.

3. Importance of Savings Calculation

Details: Understanding potential savings helps justify the initial investment in a tankless system and evaluate payback period.

4. Using the Calculator

Tips: Enter your current water heater's energy use, estimated tankless system energy use, and your local energy price (default $0.12/kWh).

5. Frequently Asked Questions (FAQ)

Q1: How do I find my conventional water heater's energy use?
A: Check your energy bills or the heater's EnergyGuide label for annual kWh consumption.

Q2: How do I estimate tankless energy use?
A: Most tankless heaters use 30-50% less energy than conventional tanks. Check manufacturer specifications.

Q3: What's a typical energy price?
A: In the US, average electricity costs $0.12-$0.20/kWh, but check your local utility rates.

Q4: Does this include installation costs?
A: No, this only calculates energy savings. Deduct installation costs to determine net savings.

Q5: How accurate are these estimates?
A: Estimates are based on energy consumption differences. Actual savings may vary based on usage patterns.
