1. What is a Heat Pump Sizing Calculator for Canada?

Definition: This calculator estimates the required heat pump size in BTUs based on your home's square footage, specifically designed for Canadian climate conditions.

Purpose: It helps homeowners and HVAC professionals determine the appropriate heat pump capacity for efficient heating in Canada's colder climate.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BTUs \) — British Thermal Units (heat pump capacity)
• \( Square\ Footage \) — Area of space to be heated (square feet)

Explanation: The formula uses a multiplier of 40 BTUs per square foot, which accounts for Canada's colder climate compared to standard calculations.

3. Importance of Proper Heat Pump Sizing

Details: Correct sizing ensures energy efficiency, proper heating capacity, system longevity, and prevents short-cycling in extreme Canadian winters.

4. Using the Calculator

Tips: Enter your home's total square footage that needs heating. The calculator will determine the recommended heat pump size in BTUs.

5. Frequently Asked Questions (FAQ)

Q1: Why is the multiplier 40 for Canada?
A: The higher multiplier accounts for Canada's colder climate compared to standard 20-30 BTUs/sq ft used in milder climates.

Q2: Should I round up the BTUs?
A: Yes, heat pumps come in standard sizes. Round up to the nearest available unit size (e.g., 24,000, 36,000 BTUs).

Q3: Does this work for all Canadian regions?
A: This is a general estimate. Northern regions may need adjustment (+10-20%) while milder coastal areas might use slightly less.

Q4: What about insulation quality?
A: Well-insulated homes might use 35 BTUs/sq ft, while older homes might need 45. Adjust accordingly.

Q5: Does this include cooling capacity?
A: Heat pumps typically have equal heating and cooling capacity, so this sizing works for both functions.
