What About BTU’s?
The BTU (British Thermal Unit) is a common measurement to describe how much energy it takes to raise the temperature of 1 pound of water by one degree (1°F).
Generally, the BTU rating on your grill indicates the maximum output of the main burners under the cooking grate. So, the higher the better, right? Not necessarily. A large, quality grill with heavy cooking grates might have a lower BTU, but if it’s better at holding and trapping heat it can cook your steak better than a cheaper grill with a higher rating.
Grills with infrared burners heat up fast and generate higher temperatures than normal grills. The BTUs should be more in the 60 to 80 BTU per square inch range.
Look for a barbecue with a snug fitting lid and heavy grill components. Grills with 80 to 100 BTUs per square inch will heat up quickly and maintain efficient cooking heat.
