1. What is a Heat Pump Energy Usage Calculator?

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

Purpose: It helps homeowners and HVAC professionals estimate electricity costs and energy efficiency of heat pump systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• kWh — Kilowatt-hours of energy consumed
• Power — Heat pump's power consumption 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 Energy Usage Calculation

Details: Understanding energy consumption helps in budgeting electricity costs, comparing system efficiency, and making informed decisions about HVAC usage.

4. Using the Calculator

Tips: Enter the heat pump's power rating in Watts (found on the unit's specification plate) and the estimated daily or monthly usage time in hours.

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. Typical residential heat pumps range from 3,000 to 15,000 Watts.

Q2: Should I use average or peak power?
A: Use the rated power unless you have variable-speed data. For more accuracy, consider using a power meter.

Q3: How does COP affect energy usage?
A: While COP (Coefficient of Performance) affects actual energy efficiency, this calculator provides basic consumption based on electrical input.

Q4: Can I calculate monthly costs with this?
A: Yes, multiply the result by your electricity rate (per kWh) and by days used to estimate costs.

Q5: Why divide by 1000?
A: This converts watt-hours to kilowatt-hours (kWh), the standard unit for electricity billing.
