1. What is a Heat Pump Hot Water Price Calculator?

Definition: This calculator estimates the total cost of a heat pump hot water system including installation and annual energy costs.

Purpose: It helps homeowners and contractors evaluate the financial aspects of heat pump water heating systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Total price (currency)
• \( I \) — Installation cost (currency)
• \( E \) — Annual energy usage (kWh)
• \( C \) — Price per kWh (currency/kWh)

Explanation: The total price combines the upfront installation cost with the projected annual energy costs.

3. Importance of Price Calculation

Details: Accurate price estimation helps in budgeting, comparing systems, and understanding long-term operating costs.

4. Using the Calculator

Tips: Enter the installation cost, estimated annual energy consumption, and your local electricity rate. All values must be ≥ 0.
