I am fairly new to the industry and have a question regarding keeping the pizza ovens on 24hrs. We have Bakers Pride ovens and we keep the ovens running 24hrs @ 525 degrees. The reasoning we were told not to turn them off or down is it would take to long for the ovens to heat up the stone. Question is how long would it take for the stone to heat back up to that temp and would any damage result to the stone cooling and heating every day? Also what would be an optimal temp be to turn the ovens down to overnight so it would only take about an hour to heat up in morning? Any insight on what you guys do would be great...Thx!
