How to find how many btus your furnace should be.
Btu to square feet cooling.
Air conditioners are rated in btu s and the btu rating determines the cooling capacity in the square footage of the living area to be cooled.
Btus stand for british thermal units and refer to the amount of energy your air conditioner is using per hour.
For example if you re trying to heat or cool 1 000 square feet you would multiply 1 000 by 20 and get 20 000 btus per hour.
Each indoor unit will be capable of providing a set number of btu s of cooling and heating power.
Obviously the problem arises when you have a very small 12 12 room for example.
Desired temperature change x cubic feet of space x 133 btus needed per hour.
1 btu hr 0 293 watts 8.
We often refer to the british thermal unit as a btu but the rating is actually the btus per hour or btu h.
1400 1500 square feet 24000 btu per hour.
According to the us department of energy directive the most appropriate size of an air conditioner would be 2 880 btu unit.

700 1000 square feet 18000 btu per hour 12.
A british thermal unit or btu is a unit of measurement of energy.
A 12 000 btu air conditioner can cool between 450 and 550 square feet of floor space.
The smaller the volume the fewer btus are required to cool or heat.
1 btu is the equivalent of 1 055 joules or 293 watts.
However volume is a more accurate measurement than area for determining btu usage because ceiling height is factored into the equation.
1 ton 11956 14 btu per hour 9.
1 horsepower 2544 4342 btu hour 10.
A simple formula to determine your heating needs is.
If you want to properly cool down a 300 square foot area or room you need a 6 000 btu air conditioner.
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.
Once you have the total square footage just multiply that number by 20 to find how many btus per hour you d need to heat or cool the space.
450 550 square feet 12000 btu per hour 11.
To figure out what size air conditioner you require you first need to determine the amount of btus you require.
Air conditioners are sized by the number of btus they put out.
This is done by calculating your square footage.
1 horsepower 745 69 watts 7.
To size your mini split air conditioner the most important thing you need to know is the square footage of the room you re looking to cool and or heat.
In order to size your mini split correctly you will need to know the square footage of the room and check it against our table.
1 watt 3 412 btu per hour 6.
The most common window air conditioning units come in cooling capacities ranging from 5 000 to 12 000 btu.
1 square meter 10 76 square feet 5.
1 btu is the energy needed to heat 1 pound of water by 1 fahrenheit.
