I use my gas grill year round even though I live in Ohio. I have noticed that the temperature gauge on the lid shows that it is 100-150 degrees cooler in cold weather (opposed to warm). The grill I have is pretty well insulated with cast iron/stainless steel construction. I have been thinking that the temperature gauge reads lower temps because it is mounted in the cover and exposed to cold temps.
I recently worked on the design of some super high temp test equipment (2700F). This equipment is fueled with propane, also located in Ohio. As a result of this project, I became aware of the vapor pressure of propane at different temperatures. Duh! I finally realized that the grill actually is running at a lower temperature/pressure.
I replaced the cheap regulator that was included with the grill with a two stage regulator (used on RV's). Very happy with the results. I can't believe I didn't realize this (vapor pressure) was the problem.
