When comparing prices, you must look beyond the sticker cost and evaluate the heating technology (deck, rotary, or convection). Deck ovens are priced based on the number of decks and trays, typically featuring independent stone soles for artisanal crusts. Rotary ovens command a higher price due to their high-volume capacity and uniform heat distribution via rotating racks. Ensure the oven uses high-grade SUS304 stainless steel for the interior chamber to prevent corrosion and high-density rock wool insulation (at least 100mm thick) to reduce energy consumption, which directly impacts long-term operational costs.
