How many BTU s do you need to heat a 750 square foot room?

Answer 1

Depending on your load the answer is different. (i.e where you are in the country)

In the deep south, its approximately 30 - 35 Btu's per square foot.

In the upper states, its approximately 50 - 60 Btu's per square foot.

So 5000 BTU's will be good for 166 sq. ft in the south and 100 sq ft in the north.

Answer 2

The question can't be accurately answered from the information given, but may be in the range of 25,000 BTU's per hour depending on a number of variables.

The amount of BTU's required per unit of time (such as per hour) will be a function of, among other things, the rate of heat loss through the room's envelope (walls, floor, ceiling, windows, doors, etc.), volume of the space, air infiltration rate, desired indoor temperature, and a design temperature for the difference between indoor and outdoor temperatures.

Answer 3

The British Thermal Unit (BTU) is the basic measure of heat energy in the Imperial system. One BTU is defined as the amount of heat necessary to raise 1 pound (0.454 kg) of water 1 degree Fahrenheit (0.55 degrees Celsius). Knowing the number of BTUs required per square foot of space is important in choosing the right size furnace and air conditioning system to heat and cool your house efficiently and effectively. You'll have to determine the amount of space to be heated or cooled and choose the right furnace or air conditioner unit for the job.

Answer 4

9000btu/hr = 2.6376kW
