How to Calculate the Right Size Furnace
- Calculate the square footage of your home.
- Find out What Climate Zone Your Home Is In Climate is another factor that helps determine how many BTUs you need to heat your home.
- Multiply your square footage by 40, the lower number recommended for the climate zone.
How many square feet will a 60000 BTU gas furnace heat?
A standard that is used by heating and cooling equipment companies is to provide at least 25 to 30 Btu of heat per square feet in the home for a moderate to warm climate. A mid-sized home of 2,000 square feet would need approximately 50,000 to 60,000 Btu to heat it properly.
How do you size a furnace for a home?
Calculating Your Basic Heating Needs You’ll want to multiply your home’s square footage by the recommended heating factor to obtain the furnace output rating you’ll need. For example: If your home is 2,400 square feet and you figure 35 BTUs per square foot, you’ll need a 84,000 BTUH-capacity furnace.

If you live in either of these cities, you will need a heater that produces 45 to 50 BTUs per square foot. Los Angeles and Atlanta, on the other hand, are in Zone 2, which means you’ll need 35 to 40 BTUs per square foot. If you live in a new home or one with good insulation, you should use the lower of these two numbers.
Do you need more BTU for bigger furnace?
Larger homes need more BTU than smaller homes (directly proportional to square footage). Homes in colder climates (Region 5) need to generate more heat than holmes in warmer climates (Region 1). To properly size a furnace, we need to use BTU heating needed per square foot for each climate zone:
What size Furnace do I need for my home?
However, there are basic “rule-of-thumb” estimations to help select the proper size for your home. In colder climates, you’ll want a furnace that generates 40 to 45 BTUs per square foot. At this amount, you’ll need 100,000-112,500 BTU furnace to heat a home of 2,500 square feet.
What size Furnace do you need?
The size of furnace you need depends mainly on the size of your home. As mentioned, a typical home in Modesto is 1500 square feet. Generally in a Californian climate you will need 25-30 BTU per square foot.
What BTU do I need for 150 square feet?
The needed capacity is influenced by the climate in your area and also by the insulation. For 150 square feet, you will need an air conditioner with a capacity of around 7.500 BTUs. For larger spaces, like 500 square feet, you will need a capacity of 14.000 BTUs.
How many BTU to heat a room?
Calculate the total number of BTUs required to heat the home. For each room, multiply the BTU per square footage times the square footage of the room. For example, a home located in Zone 5 with poor insulation would require 60 BTUs per square foot. Therefore, a room that is 300 square feet will need 18,000 BTUs (60 x 300).
