What is the difference between a commercial oven and a household oven?

Please verify the following points and require itemized written supplier responses:（commercial oven oven-comparison） Commercial ovens have more trays, larger capacity and heavier-duty heating, insulation, fans and doors for continuous service. Check tray count, tray size, rated power, duty time and spare parts. Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
