Heating or Cooling?
The gas meter on your house is sufficient,
What ever it take to keep you warm - and add moisture to keep it toasty.
I am looking for a window AC unit to use in my whole house. What is the BTU's one would need to cool a whole house?
11800 BTU/hr is 3.46kW
2000 sq. ft. x 5o (based on climate zone)=100,000 btus so; between 80k-100k(100,000 Btu's needed) 80% Efficient furnace: 125,000 Btu capacity; 90% Efficient:110,000 Btu capacity; 95% Efficient: 105,000 Btu capacity.go here.http://www.gasfurnacepricesonline.net/22/what-size-furnace-do-i-need-for-a-2000-square-foot-house/
77,550 BTU/hr = 22.728kW
50,000 btu
The BTU usage depends on the size generator. What you need to know to figure this out is the fuel type (propane or natural gas) and the size of the generator (usually measured in kilowatts or KW) and the size of the engine. Once you know these things, you can calculate the BTU. The easiest way is to ask the sales person or manufacturer. They can tell you the BTU.
Almost 340,000 BTU per hr
Check with your utility company; you may have other gas utilities in use as well.
2180 SqFt/500 = 4.4 tons of AC required x12000 BTU/ton = 52800 BTU's Answer is it takes 52800 BTU's to cool a 2180 SqFt home
If your home actually requires the 2MM btu then that is the output you need, if your furnace is 60% efficient then you would need 3,333,333 btu input to produce 2,000,000 btu output, There are 1000 btu per cubic foot of natural gas therfore you would burn 3333 cubic feet of gas to produce 2MM btu. Your question cannot be answered here because I don`t know what you pay per cubic foot of ng nor did you give a time frame for how long you plan on heating the house. But now you know the figures and you can do the math.
