48,000 input or output? If 48K is the input to an 80% efficient furnace, than the output would only be 38,400. It also depends on where the house is located, because 48K will heat a much larger house in Miami than it would in Minneapolis. You need to post more info to get a worthwhile answer. But to give you an idea I heat 1000 sq ft in NJ easily with a 52,500 80% efficient furnace which yields 42,000 output.
You take the size of your home in square feet and times it by how many rooms you have. A 70,000 BTU furnace will heat a house 1600 square feet.
Furnace volume is typically measured in cubic feet, not square feet. This measurement refers to the total space within the furnace where combustion takes place and heat is generated. Square feet is used to measure the surface area of a space, while cubic feet measures the total three-dimensional volume.
Will a 40,000 btu furnace be enough to heat my 1375 square foot middle unit town house.
It heats all the square feet in the network of rooms through which it's distributed.How warm it heats them, and how fast, depends on the height of the ceilings, andon the rate of loss of heat through the walls, which in turn depends on the outsidetemperature and the insulation efficiency of the walls.
how many square feet will 26,000.00 heat
You cannot accurately determine what size furnace is required based on the total square feet of a given space or structure. To accurately determine how much heat is required to heat your, you would need to have a Manual J Heat Load Calculation performed.
Florida or North Dakota?
It takes about 50,000 btus to heat 1000 square feet
how many square feet does a 14,000 btu heater heat
A 200,000 BTU wood burning stove will heat 1,000 square feet.
4800 BTUs will 150 square feet.
Actually you really need to know height of the area, too since you are trying to heat or cool xxx number of cubic feet. the difference between an 8ft, 10ft, 12ft or higher ceiling will make a BIG difference.
