The Holland Grill's BTU Output for Stainless Steel Units
You might notice in your extensive grill research that Holland's stainless steel grill uses 14,000 BTU's and the aluminum grills are set for over 20,000 BTU.
For an explanation of this, we sought out the advice of our crack service department technical advisors. Here's what they say: "BTU rating are simply a calculation based primarily on gas pressure & orifice size, or the amount & type of gas burning per hour (heat output per hour). Since stainless steel retains heat better than the other grill materials, it requires less gas to heat stainless steel grills to the same temperature. Therefore, stainless steel grills are intentionally designed with a slightly smaller orifice in the gas valve than black grills. You could say that stainless steel grills get better "gas mileage" than black grills. All full sized Holland grills, no matter which material, are designed to heat to the SAME temperature. It is TEMPERATURE that cooks your food...not BTU's.
Couldn't have said it better myself.
