the closed oven is heavily insulated. The dissipated heat energy is much less. it will never hit the room air at much more than ambient temp. so it will lose all inertia faster and not radiate the heat as far. If you open the door, it will change the ambient temp and transfer the stored energy to surrounding surfaces, more likely to make it to the thermostat. I guess a lot depends on where the thermostat is too.
My oven is super efficient, other than when its venting, you dont know its on, no matter the temperature its set to, for all i know its dissipating the heat into the electrical cord On Fri, Feb 14, 2020 at 2:18 PM Nate Burke <[email protected]> wrote: > But if the same energy is going in the room, won't it have the same > effect, Door open/shut?
