1. What is a Heat Pump kWh Calculator?

Definition: This calculator estimates the electrical energy consumption (in kWh) of a heat pump based on its heat output and coefficient of performance.

Purpose: It helps homeowners and HVAC professionals understand the energy efficiency and operating costs of heat pump systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kWh)
• \( Q \) — Heat output (BTU)
• \( COP \) — Coefficient of Performance (typically 3-5)
• 3412 — Conversion factor from BTU to kWh

Explanation: The formula converts BTU heat output to equivalent kWh while accounting for the heat pump's efficiency (COP).

3. Importance of Heat Pump Efficiency Calculation

Details: Understanding energy consumption helps in comparing systems, estimating operating costs, and evaluating energy savings.

4. Using the Calculator

Tips: Enter the heat output in BTU and the COP (default 3.5). Typical COP values range from 3-5 for modern heat pumps.

5. Frequently Asked Questions (FAQ)

Q1: What is COP in heat pumps?
A: COP (Coefficient of Performance) measures efficiency - the ratio of heat output to electrical energy input.

Q2: What's a typical COP value?
A: Most modern heat pumps have COP values between 3-5, meaning they produce 3-5 times more heat energy than the electrical energy they consume.

Q3: How do I find my heat pump's COP?
A: Check manufacturer specifications or energy guide labels. It may vary with outdoor temperature.

Q4: Why 3412 in the formula?
A: This is the conversion factor from BTU to kWh (1 kWh = 3412 BTU).

Q5: Does this include defrost cycles?
A: No, actual consumption may be slightly higher due to defrost cycles and auxiliary heating.
