1. What is a Heat Pump 18000 BTU Calculator?

Definition: This calculator estimates the required heat pump capacity based on area size and BTU per square foot requirements.

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

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = A \times \text{BTU/ft}^2 \]

Where:

\( Q \) — Heat pump capacity (BTU/h)
\( A \) — Area to be heated/cooled (square feet)
\( \text{BTU/ft}^2 \) — BTU requirement per square foot (BTU/h·ft²)

Explanation: The area is multiplied by the BTU requirement per square foot to determine the total heat pump capacity needed.

3. Importance of Proper Sizing

Details: Correct heat pump sizing ensures energy efficiency, proper temperature control, and system longevity.

4. Using the Calculator

Tips: Enter the area in square feet and BTU per square foot (default 20 BTU/h·ft²). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical BTU/ft² requirement?
A: Most homes need 20 BTU per square foot, but this varies by climate, insulation, and other factors.

Q2: How does this relate to an 18000 BTU heat pump?
A: An 18000 BTU unit typically covers about 900 sq ft (at 20 BTU/ft²).

Q3: When would I adjust the BTU/ft² value?
A: Increase for poor insulation, cold climates, or high ceilings; decrease for well-insulated spaces or mild climates.

Q4: What if my calculation exceeds 18000 BTU?
A: You may need a larger unit or multiple heat pumps for adequate coverage.

Q5: Does this include cooling capacity?
A: Yes, heat pump capacity typically applies to both heating and cooling.
