1. What is a Ducted Heat Pump Size Calculator?

Definition: This calculator estimates the required BTU capacity for a ducted heat pump system based on the square footage of the space.

Purpose: It helps HVAC professionals and homeowners determine the appropriate size for a ducted heat pump system.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BTUs \) — British Thermal Units (cooling capacity)
• \( Square\ Footage \) — Area to be cooled (square feet)

Explanation: The square footage is multiplied by 40 BTUs per square foot, which is a standard rule of thumb for sizing ducted heat pump systems.

3. Importance of Proper Sizing

Details: Correct sizing ensures efficient operation, proper cooling/heating, and prevents short cycling or insufficient capacity.

4. Using the Calculator

Tips: Enter the total square footage of the space to be conditioned. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 40 BTUs per square foot?
A: This is a general guideline for moderate climates. Adjustments may be needed for very hot or cold regions.

Q2: What factors can affect this calculation?
A: Ceiling height, insulation quality, window size/orientation, and local climate can all impact sizing needs.

Q3: Should I round up the calculated BTUs?
A: Heat pumps come in standard sizes. Choose the next available size if your calculation falls between standard capacities.

Q4: Does this work for both heating and cooling?
A: This calculation primarily addresses cooling needs. Heating requirements may differ based on climate.

Q5: What if my home has unusual features?
A: Consult with an HVAC professional for homes with high ceilings, poor insulation, or significant glass areas.
