1. What is a Heat Pump Electricity Usage Calculator?

Definition: This calculator estimates the electricity consumption of a heat pump based on its power rating and operation time.

Purpose: It helps homeowners and energy professionals understand and predict heat pump energy consumption for better energy management.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• kWh — Kilowatt-hours (energy consumption)
• Power — Heat pump's power rating in Watts
• Time — Duration of operation in hours

Explanation: The formula converts watt-hours to kilowatt-hours by dividing by 1000, which is the standard unit for electricity billing.

3. Importance of Electricity Usage Calculation

Details: Accurate energy consumption estimates help in budgeting electricity costs, evaluating energy efficiency, and comparing different heat pump models.

4. Using the Calculator

Tips: Enter the heat pump's power rating in Watts (found on the nameplate or manual) and the expected operation time in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my heat pump's power rating?
A: Check the manufacturer's specifications, nameplate on the unit, or product manual. It's typically listed in Watts (W) or kW (1 kW = 1000 W).

Q2: Should I use average or peak power?
A: For continuous operation, use the rated power. For cycling operation, use an average based on the duty cycle.

Q3: How does COP affect electricity usage?
A: While COP affects efficiency, this calculator shows electrical input only. Actual heating/cooling output would be power × COP.

Q4: Can I use this for monthly estimates?
A: Yes, multiply daily usage by 30, or calculate based on average daily run hours.

Q5: How accurate is this calculation?
A: It provides theoretical consumption. Actual usage may vary based on temperature settings, climate, and heat pump efficiency.
