What is BTU? How much do I need?
BTU stands for British Thermal Units, and is the measurement of energy output from your grill. It is defined as the amount of heat that is required to raise the temperature of one pound of water by one degree Fahrenheit. All grills have different BTU outputs. but the key to finding a good grill is to look for 80 to 100 BTU per square inch of cooking space. Higher BTU models will burn fuel faster, so keep that in mind.
