can be taken from the heating elements that can also bake also if steaming is not required there is little or no heat loss attributable to the steam generator other advantages of the embodiments include reduced manufacturing costs as the amount of insulation support brackets elements control system wiring and sheeting associated with an external steam generator is reduced improved maintenance and reliability is also an advantage as the embodiments tend to be more resistant to limescale especially as there are no nozzles present and even if limescale does build up then it is more easy to maintain than earlier arrangements however tests have shown that little lime scale builds up on the collector 17 as the conversion of the water into steam involves quite u201c violent u201d boiling and so the water is scattered and can be blown out of the oven furthermore no pumps thermocouples contactors air compressors water tanks float valves etc are essential the internal steam generator also means that the oven has a smaller foot print thereby saving space and the oven depth can also be reduced the oven can also have a reduced power kw rating as the same heating elements are used for producing steam as for baking as well as this reduced energy consumption the amount of water needed by the oven to steam is also less than for conventional ovens having separate tiles and heat collectors has the advantage of being easy to remove and clean they can also be modular for the production of ovens having different widths they provide even steam distribution and even heat collection it is also possible that the collector and shelf could be combined into a single.
