What size furnace do I need for a 2000 square foot house?
A mid-sized home of 2,000 square feet would need approximately 50,000 to 60,000 Btu to heat it properly. With a less efficient furnace operating at 80 percent efficiency this would require a 60,000- to 72,000-Btu furnace.
How many BTU does a square foot furnace use?
A furnace that is too large will waste energy and create warm spots at grates near the furnace before the cycle ends. The generally accepted BTU per square foot heating rule of thumb ranges from 30 BTU per square foot to 60 BTU per square foot.
How many BTUs do you need to heat a house?
If you’re building a house, you may be wondering how many BTUs you’ll need to heat it. The first factor you should consider is your home’s square footage. Bigger homes, generally speaking, require more BTUs to heat. Keep in mind, however, that this is just a starting point.
How big of a furnace do you need in Los Angeles?
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.
How is the size of a furnace determined?
The size of a furnace is based on how much heat it can produce in an hour, as measured in BTUs, or British thermal units. A BTU is the energy required to heat a pound of water by one degree Fahrenheit. The higher the BTU rating a furnace has, the more warmth it can provide. What’s the Right Size Furnace for My Home?
How big of a furnace do I need for a 1, 200 square foot house?
Below are the BTUs required for homes of certain sizes. 1,200-square-foot house: 36,000 to 72,000 BTUs 1,500-square-foot house: 45,000 to 90,000 BTUs 1,800-square-foot house: 54,000 to 108,000 BTUs
How to calculate furnace BTU for your home?
Choose… The basic principles the furnace sizing calculator is based on are: 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).
How many BTU’s are needed to heat 1000 square feet?
In more moderate climates, multiply by 20 – 30. And in cold climates multiply the square foot number by 30 – 40. For example, if you’re trying to heat 1000 square feet in a cold climate, 30,000 – 40,000 BTU’s will add significant warm air to your home.
