What makes a hotter barbecue, propane or natural gas?
Answer: Propane as a gas burns higher and hotter than natural gas. However, when a barbecue is manufactured for use with natural gas, specific valves are used. These valves allow more natural gas to enter the barbecue’s burner systems. So, while natural gas is slightly cooler than propane, more of it is being burnt and the heat produced by the barbecue should be identical whether you buy the propane or natural gas model.
