What are the differences between ovens designed for restaurants, caterers, and the home/garden?
There are a number of differences. Commercial ovens are designed to withstand the rigors of being fired 365 days per year – cooking hundreds of pizzas under high heat for 12 hours per day. The thermal mass and weight of commercial ovens is significantly larger than home and catering ovens, and the refractory materials and insulation utilized are designed for higher heat and higher duty.
