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. A simple formula to determine your heating needs is: (desired temperature change) x (cubic feet of space) x . 133 = BTUs needed per hour.
How many BTU do I need per square foot?
To determine the number of BTUs per square foot that you need to heat a room, simply multiply the square footage by 20 BTUs per square foot. For example, if a room has 1,000 square feet, you would require 20,000 BTUs to heat it.
How do you calculate BTU for a room?
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).
What is the formula for BTU?
BTU = Flow Rate In GPM (of water) x (Temperature Leaving Process – Temperature Entering Process) x 500.4*Formula changes with fluids others than straight water.
How many BTU do I need for a 12×12 room?
If you want to properly cool down a 300 square foot area (or room), you need a 6,000 BTU air conditioner. Obviously, the problem arises when you have a tiny 12×12 room, for example. According to the US Department of Energy directive, an air conditioner’s most appropriate size would be 2,880 BTU unit.
How many BTU do I need for 3500 square feet?

How many BTUs is 1hp aircon?
When choosing an air conditioner, usually a 1 HP (horse power) equipment is able to remove 9,000 BTU/hr of heat. With better technology, some machines are able to remove 10,000 BTU/hr of heat with the same capacity. The higher the listed BTU/hr, the greater the cooling capacity.
How do you calculate BTU per hour?
BTU/hr is measure of the thermal or heat energy generated per hour and is a measured to used specify air conditioners. The formula for calculating BTU/hr is: Heat Dissipation (Watts) x 3.4192 = BTU/Hr. So if a server has a heat dissipation (output) of 500 Watts the thermal or heat energy generated is 1709.6 BTU/hr.
Where is the BTU on an air conditioner?
Find the model number. Within this string of letters and numerals, you should find an even, two-digit number. The possibilities on residential units range from 18 to 60. Divide the number by 12 (which represents 12,000 Btu/hr, or one ton of cooling capacity) to get your AC unit’s tonnage.
What is a BTU hour?
One Btu is the amount of heat required to raise one pound of water by one degree Fahrenheit. Btus per hour (Btuh) is the benchmark used to estimate the capacity of heating systems, such as gas furnaces.
How many sq ft does a 15000 BTU AC cool?
Those in the 12,000- to 15,000-Btu range cost from $450 to $600, while large units go up to $1,200. Air conditioners rated at 15,000 Btu should be enough to cool most rooms up to about 875 sq. ft.
How many BTU do I need for a 20×20 room?
Rule of thumb. A 1 ton (12,000 BTUH) unit is doable in the space you want to cool. To handle the hot, humid summer heat of your area, I would increase it to 15,000 – 16,000 BTUH.
Is 8000 BTU enough for a bedroom?
Recommended BTU By Room Size If you are looking for an air conditioner for a room measuring say 10′ x 15′ (150 square feet), the recommended BTU range is up to 5400. Once you get into 340 and 400 square feet per room, you’d need an 8,000 or 9,000 BTU air conditioner, respectively.
What size air conditioner do I need for a 2400 square foot home?
The answer to the question, “what size AC unit for 2400 square feet?”, would be, is 60,000 BTUs or 5 Tons. It’s possible to fall between unit sizes, so if that’s the case with you, then you should choose the next higher size. That way, you can be sure that the AC unit can still cool a given area sufficiently.
