Read the tag on your furnace for the input/output rating. American Standard and all other manufacturers make more than one size furnace.
Divide the btu output rating by the btu input rating. Both of these values can be found on the furnace`s nametag.
It depends on the furnace, they come in different sizes. There should be a data plate on or in the furnace which lists the input and output rating.
Approx 1000 BTU per standard cubic foot
The output rating of a 96% efficient boiler or furnace rated at 100,000 input.
100,000 btu input. The output depends on the efficienct rating of the furnace, ie 95%efficient = 95,000 btu output, 80% = 80,000 btu output.
you are referencing a 75,000 BTU furnace.
For the purpose of gas rating 1040 btu's/ft3
67,500 BTU electric furnace
The BTU output requirements of your furnace must be determined by heat load and heat loss calculations on the area that is heated. You should consult several HVAC contractors for estimates and recommendations.There are many factors that influence the BTU requirements of a furnace in any location.
Oil has the higher BTU rating Depends. If it is Liquified Nat. Gas then it has the higher rating.
Gas usage is measured in cubic feet because it is a vapor. Look at the tag on your furnace and find the input rating, natural gas contains roughly 1000 btu per cubic foot. So divide the input rating by 1000 and you have your answer.
Heptane has the chemical formula of C7H16. It has a BTU rating of 19,163 BTU per pound and a rating of 4,465.8 kilojoules per mole.
