    By definition, a BTU is the amount of energy required to raise one pound of wat â¦ er one degree F.     But you have one gallon of water, which weighs approximately* 8.34 pounds. So, you'd need 8.34 BTU to increase one gallon of water one degree F.     Note how the amount of time was not important. BTU is required to raise 1lb of water 1 degree F in 1 hour. 212-75=137 degrees 600 lbs water x 137 degrees= 82,200 BTU's required to change 75 degree water to 212 degree w â¦ ater.
