1. What is a Heat Pump Cost Calculator?

Definition: This calculator estimates the operating cost of a heat pump based on its heat output, efficiency (COP), electricity cost, and operating time.

Purpose: It helps homeowners and HVAC professionals estimate energy costs for heating or cooling with a heat pump system.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Operating cost ($)
• \( Q_{btu} \) — Heat output (BTU/h)
• \( COP \) — Coefficient of Performance (dimensionless)
• \( P_{kwh} \) — Electricity cost ($/kWh)
• \( t \) — Operating time (hours)

Explanation: The formula converts BTU output to kW, accounts for heat pump efficiency, then calculates cost based on electricity price and runtime.

3. Importance of Heat Pump Cost Calculation

Details: Accurate cost estimation helps with budgeting, comparing systems, and understanding energy efficiency benefits.

4. Using the Calculator

Tips: Enter the heat pump's output in BTU/h, its COP (typically 3-4 for modern systems), your electricity rate, and expected operating time.

5. Frequently Asked Questions (FAQ)

Q1: What is COP and where do I find it?
A: COP (Coefficient of Performance) measures efficiency. It's in your heat pump's specifications, typically ranging from 2.5 to 5.0.

Q2: Why 3412 in the formula?
A: This converts BTU/h to kW (1 kW = 3412 BTU/h), needed to calculate electrical consumption.

Q3: What's a typical electricity cost?
A: Average U.S. rates are $0.10-$0.30/kWh. Check your utility bill for exact rates.

Q4: How do I estimate operating time?
A: For seasonal estimates, calculate average daily runtime × days used. For short-term, use actual expected hours.

Q5: Does this include installation or maintenance costs?
A: No, this only calculates operating (energy) costs. Other expenses should be considered separately.
