Hey there, Mike here. If you're considering an electric furnace for your mobile home, getting the size right is essential. An undersized unit won't keep you warm, while an oversized one can lead to inefficiency and higher bills. Let's break down how to choose the perfect fit.
1. Calculate Your Home's Square Footage
Start by determining the total square footage of your mobile home. Measure the length and width of each room, multiply them to get the area, and then sum up all the rooms. For example, a 14x70 single-wide mobile home has approximately 980 sq ft. Hunker
2. Understand BTUs and kW
Heating capacity is measured in BTUs (British Thermal Units) or kilowatts (kW). One kW equals about 3,412 BTUs. So, a 20 kW furnace produces roughly 68,000 BTUs. HVAC OptimizerHow to Choose Best HVAC Systems
3. Consider Your Climate Zone
Your location affects heating needs. Colder climates require more BTUs per square foot. Here's a general guideline:
-
Warm climates (Zone 1 & 2): 20-25 BTUs per sq ft
-
Moderate climates (Zone 3 & 4): 30-35 BTUs per sq ft
-
Cold climates (Zone 5 & above): 40-45 BTUs per sq ft
For instance, in a moderate climate, a 1,000 sq ft home would need about 35,000 BTUs, or approximately 10 kW.
4. Factor in Insulation and Home Features
Well-insulated homes retain heat better, potentially reducing furnace size requirements. Consider:
-
Insulation quality: Walls, floors, and ceilings
-
Window types: Single vs. double-pane
-
Ceiling height: Higher ceilings may require more heating
If your home lacks proper insulation, you might need a furnace with higher capacity.
5. Use a Furnace Sizing Calculator
For a more precise estimate, consider using an online furnace sizing calculator. These tools factor in square footage, climate zone, and insulation levels to recommend an appropriate furnace size.
6. Consult with a Professional
While these guidelines are helpful, consulting with an HVAC professional ensures accuracy. They can perform a Manual J calculation, considering all variables to recommend the best furnace size for your specific needs The Furnace Outlet
Final Thoughts from Mike
Choosing the right electric furnace size is vital for comfort and efficiency in your mobile home. By considering your home's square footage, climate, and insulation, you can make an informed decision. Remember, when in doubt, consult with a professional to ensure optimal performance.
