Home double oven heat transfer regulations

Iain Robinson

There is a  problem in a double oven (one above the other) but in the same carcass (Shell). When the bottom oven is on and running at 200C the top oven, which is switched off,  is warmed by heat from the bottom oven. The top oven temperature  has been measured at 100C of heat transfer. The same is true, but to a lower temperature, if the top oven is on and the bottom oven is off.

 

I am trying to find the specification/regulation for the double ovens that states what the permissible heat transfer is.

    I wonder if the heat loss from the lower oven (into the upper one) might cause difficulty for the energy efficiency regulations. Or on the other hand, it might be the case that the heat loss from one oven to another is much like it used to be, but better thermal insulation around the pair of ovens means that the same amount of heat finds it much more difficult to escape from the second oven, so produces a far greater temperature rise.

    Makes sense to me.

    In the days of freestanding cookers, the grill cavity was ideal for warming plates when the oven was on.

    On the basis that nobody is going to want an oven at less than 100 deg C, I don't really see a problem, but the heat conservation is poor.

    Hi Andy

    Energy Efficiency regulations sound like a good route to go down - but do you know what they are?

    Chris the big issue is that any unsuspecting person can get burnt at much lower temperatures, but at 100C the from door to the oven is above 40C and that is an issue for a child.

    Oven doors get hot.

    What age of child are you thinking of?

    A toddler who is just about walking will put his or her hands against a wall in order to climb up it. If that wall is an oven door, there will be trouble. The toddler cannot withdraw because the hands are providing the support, so the palms get burned. Not nice so mothers (and fathers) have to be very careful in the kitchen.

    All that said, why is the heat in the upper oven a problem? I see no reason why the two ovens should be insulated from each other.

    Is there a hidden agenda here?

    Chris - you ask the question " why is the heat in the upper oven a problem?" - the problem is that in a proper heat efficient oven with proper thermal insulation between the ovens -  it should not be there at all.

    That is unrealistic.

    Of course one could improve the insulation, but then the ovens' capacity would be much reduced. How would that suit you?
