1. What is a Heat Pump Running Cost Calculator?

Definition: This calculator estimates the operating cost of a heat pump based on energy consumption and electricity rates.

Purpose: It helps homeowners and businesses estimate the energy expenses associated with running a heat pump system.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Cost} \) — Running cost (currency)
• \( \text{kWh} \) — Energy consumption (kilowatt-hours)
• \( \text{price} \) — Electricity price (currency per kWh)

Explanation: The energy consumption is multiplied by the electricity rate to determine the total operating cost.

3. Importance of Running Cost Calculation

Details: Understanding operating costs helps with budgeting, comparing systems, and evaluating energy efficiency improvements.

4. Using the Calculator

Tips: Enter the heat pump's energy consumption in kWh and your electricity rate (default $0.15/kWh). Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my heat pump's kWh usage?
A: Check your energy bills, use a smart meter, or multiply the unit's power rating by its operating hours.

Q2: What's a typical electricity rate?
A: Rates vary by location but average $0.10-$0.30 per kWh in the US. Check your utility bill for exact rates.

Q3: Does this include seasonal variations?
A: No, this calculates cost for the entered usage. For annual estimates, calculate monthly and sum the results.

Q4: How can I reduce my heat pump running costs?
A: Improve insulation, maintain your system, use a programmable thermostat, and consider a more efficient model.

Q5: Does this account for COP (Coefficient of Performance)?
A: No, this calculates cost based on electrical input. The COP is already factored into your kWh usage.
