Roomy contention: I MUST leave our oven door open wide after cooking so as not to waste the heat. Even though the stove/oven is NOT vented to the outside in our kitchen, because the oven is insulated heat will some how [evaporation?] disappear.

My standing: Heat doesn't disappear and the entirety of the heat will be transferred into the kitchen, albeit at a slower rate than leaving the oven door open.

Ugh. Bourbon time.

I leave mine open for the faster transfer.

All I know is this. When you leave the door open after using the oven, it heats my apartment up noticeably.

That makes sense. The heat will dissipate into the kitchen. The rate is the variable.

Open a crack - like for broiling - not a wide open 24x30 kitchen obstacle.

Faster heat transfer for the win.

Opening the door will not only cool the oven quicker, but will contribute to the temp in the room.

Leaving it open a bit makes sense.

While the OP is technically correct from an energy standpoint, the roommate is right from the standpoint of air temperature and physiological aspects.

Leave the frigging door open, it isn't that big an issue.

If you trap the heat inside the oven for a longer period, won't more of the heat escape through whatever wall it's next to than would have with the door open? If it's next to an exterior wall, might make a difference.

Whether that difference would be noticeable or not, who knows? I am not a maths expert.

If you don't notice an effect, then you really are wasting the heat. Open that door up and enjoy the warmth all at once. Why let it out slowly so as to not heat the place up in a manner that you could both enjoy?

The exterior wall scenario is the only case where it might make sense to leave the door open. Just leave it open a crack, otherwise the risk of tripping someone isn't worth any energy savings.

So are you proposing that the rate of transfer is meaningless or just that it is meaningless to you.

My stove has a small vent that comes up threw the rear burner from the oven.

If you leave the oven door closed after using it, it will provide a small amount of heat around the oven for a long time.

If you leave the oven door open after using it, it will provide a large rush of heat throughout the apartment.

Do you sleep near the oven? If yes, close it after use......If not, leave it open.

OP, you are correct that the heat energy rate transfer is the only thing that changes.

If the rate of heat energy out of the closed oven is slower than the apartment loses heat to the outside you will not notice a rise in the apartment room temperature, but the apartment will require the apartment heater provide less heat energy in proportion to the heat being supplied by the oven. If the apartment loses heat slower than the closed oven then the room temperature will rise.

If you open the door, the heat transfer rate increases and wil likely cause a noticeable but temporary rise in the apartment air temperature. The oven will cool to room tempeature much more quickly than when the door is closed.

In either scenario, the amount of heat transfered is the same for a given oven temperature (all else being equal). The difference is the rate of transfer.

ETA: OP, this is a simple First Law of Themodynamics question; energy is not created or destroyed, the change in the internal energy of a system is equal to the amount of heat supplied to the system, minus the amount of work performed by the system on its surroundings. The rate of the work becomes a question of "power", but that is for another thread.

I prefer opening the door a crack, for faster transfer and the brief rise in room temperature.

You're right, you should seal off all the heat vents in the apartment too. The heat will slowly transfer from the ducts through the floor/wall into the room and you will get the same benefit.

the heat gained from the oven over the time it takes to equalize to room temp. with the door closed is less than the amount of heat lost (from the house) over the same interval.

OR no noticeable change or this time of year cooler temp inside house.

The heat gained from opening the door for a short time is greater than what is lost over the same time interval from the house. OR room gets warmer.

At least how i understand it
Link Posted: 1/5/2012 3:40:12 PM EDT
Let throw another variable out..

When you open the door open wider - the oven light comes on... So is the heat gained 'free', or are the savings used up by the electricity lighting the bulb..

I've got to believe it would cost more in gas to heat the room up that much in a short period of time given the kw/hr rate and the size of that bulb.
