Calculating the number of BTUs needed to heat an area For example, a 300 square foot room typically requires 7,000 BTUs to maintain a comfortable temperature, while a 1,000 square foot room requires 18,000 BTUs. How many sq ft will a 2.5 ton AC cool? Units that are 2.5 tons can cool off 1201-1500 square feet, etc.
How many BTUs does a furnace need for a house?
For cooler climates, a very broad estimate of furnace sizing is to select one that generates 40 to 45 BTUs per square foot. At 40 to 45 BTUs per square foot, you’d need a 100,000 to 112,500 BTU furnace to heat your 2,500-square-foot home.
What is the recommended BTU per square foot?
The general rule of thumb is that furnaces need to provide 25 to 30 BTU output per square foot in moderate climates and 40 BTU output per square foot in colder regions.
How do you calculate BTU requirement?
The BTU requirement will be for the whole room, so you need to calculate the total amount of space the room covers. To do that you need to measure the length, width and height of the room so you can then calculate the cubic footage of each room by multiplying the length, width and height of the room.
