1. What is Electric Furnace Sizing?

Electric furnace sizing involves determining the appropriate heating capacity (in kilowatts) needed to efficiently heat a specific area in Canadian homes. Proper sizing ensures optimal comfort and energy efficiency.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• \( kW \) — Furnace size in kilowatts
• \( Area \) — Living space area in square feet
• \( 10^{-12} W/ft² \) — Standard heating load factor for Canadian homes

Explanation: This formula calculates the required furnace capacity based on the area to be heated, using standard Canadian heating load calculations.

3. Importance of Proper Furnace Sizing

Details: Correct furnace sizing is crucial for energy efficiency, comfort, and system longevity. An oversized furnace cycles too frequently, while an undersized one struggles to maintain temperature.

4. Using the Calculator

Tips: Enter the total living area in square feet. Ensure accurate measurements for best results. This calculator is specifically designed for Canadian home conditions.

5. Frequently Asked Questions (FAQ)

Q1: Why is furnace sizing important for Canadian homes?
A: Proper sizing ensures efficient heating during cold Canadian winters while minimizing energy costs and equipment wear.

Q2: What factors affect furnace sizing besides area?
A: Insulation quality, window efficiency, ceiling height, climate zone, and home orientation also impact heating requirements.

Q3: Is this calculator suitable for all Canadian regions?
A: This provides a general estimate. Northern regions may require additional capacity, while milder coastal areas may need less.

Q4: Should I consult a professional for final sizing?
A: Yes, always consult with a qualified HVAC professional for precise furnace sizing and installation.

Q5: How often should furnace sizing be recalculated?
A: Recalculate after major renovations, insulation upgrades, or when replacing an existing system.
