1. What is a Heat Pump Efficiency Rating (SEER)?

Definition: SEER (Seasonal Energy Efficiency Ratio) measures how efficiently a heat pump cools by comparing cooling output to electricity input.

Purpose: It helps consumers compare energy efficiency of different heat pump models and estimate operating costs.

2. How Does the SEER Calculator Work?

The calculator uses the formula:

Where:

• \( SEER \) — Seasonal Energy Efficiency Ratio (BTU/Wh)
• \( Cooling\ Output \) — Total cooling provided (BTU)
• \( Electricity\ Input \) — Total electrical energy consumed (Wh)

Explanation: Higher SEER values indicate more efficient systems that provide more cooling per unit of electricity.

3. Importance of SEER Rating

Details: SEER ratings help determine energy costs, environmental impact, and qualify for energy efficiency rebates.

4. Using the Calculator

Tips: Enter the total cooling output in BTU and electricity consumption in Watt-hours. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a good SEER rating?
A: Modern systems range from 14-22 SEER. Higher is more efficient. Minimum is 14 SEER in most regions.

Q2: How is this different from HSPF?
A: HSPF measures heating efficiency, while SEER measures cooling efficiency.

Q3: Where do I find cooling output and electricity input?
A: Check manufacturer specifications or energy guide labels on equipment.

Q4: Does SEER account for seasonal variations?
A: Yes, SEER is calculated under varying conditions to represent seasonal performance.

Q5: How much can I save with higher SEER?
A: Each SEER point increase typically saves 5-10% on cooling costs.
