When sourcing AGA-style BBQ grills, prioritize high-grade 304 stainless steel for the body and cooking grates to ensure maximum corrosion resistance. For the cooking system, look for cast iron burners or heavy-duty infrared burners that provide even heat distribution. Ensure the grill features high-density insulation (similar to traditional AGA cookers) to maintain consistent temperatures and improve fuel efficiency. Additionally, verify that the BTU output per burner aligns with your performance requirements, typically seeking at least 10,000 to 12,000 BTUs for primary cooking zones.
