• #### How many Btus does it take to heat 1 gallon of water 1 degree?

One BTU is the amount of heat energy required to raise one pound of water by 1ºF. Water weighs 8.33 pounds per gallon so we can calculate that one gallon of water requires 8.33 BTU to raise the temperature 1ºF. 1 Pound of Gas (1 PSI) = 28″ Water Column (w.c.) 1 Pound of Gas (1 PSI) = 16 Ounces (oz.)

• #### How many BTU is a furnace?

Average BTU Ratings. A typical furnace is rated at 100,000 or 80,000 BTU per hour, but furnaces might be as small as 40,000 or as large as more than 200,000 BTU. A 90 percent high-efficiency rated at 60,000 BTU will deliver about 54,000 BTUs per hour of heat energy to your home.
• #### How many tons of AC do I need per square foot?

Understand here that the standard practice among HVAC contractors sizing air conditioners for new homes is to use a rule of thumb. It's often in the neighborhood of 1 ton of air conditioning capacity for each 600 square feet of conditioned floor area, usually abbreviated 600 sf/ton.
