Overview
The Thermora A-TR-GG is a freestanding propane grill with three burners and 553 square inches of cooking area, built from cast iron and stainless steel. It is a mid-size option for households that grill regularly but do not need commercial-scale grate space.
Cast iron grates hold heat and produce stronger sear marks than stamped steel, though they need seasoning and drying to avoid rust, unlike the stainless steel panels elsewhere on the unit. No BTU figure is listed, so total heat output is unknown.
- 3 burners, 553 sq in cooking area
- Cast iron and stainless steel construction
- Propane fuel
- Freestanding install
Who it's for
Good fit for someone who wants cast iron sear quality on a mid-size three burner grill. Less suited to anyone who wants a fully stainless, low maintenance grate.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cast iron grates for stronger sear retention
- 553 sq in area across three burners
- Freestanding, no built-in cutout required
- No BTU rating listed to gauge total heat
- Cast iron grates require seasoning and rust upkeep
Performance notes
Three burners cover 553 square inches, reasonable room for multiple zones without stretching into commercial territory. Cast iron grates retain heat well once preheated, helping with consistent sear marks, though they need oiling and drying after cleaning to resist rust.
