Leave the oven door open after use in winter?

[Rat407]

Leave open.

Inside wall probably makes no difference assuming no loss through floor. Outside wall? Maybe helps.

Yup - both of our ovens are in a boxed space - 100% in the kitchen with a room behind that wall …

If the house HVAC has cooling on, I close the door after use. If the house HVAC has heat on I leave the oven door open after use. Not sure it does a whole lot but seems to make sense to me.

It will make no difference thermodynamically - you get the heat fast or slow. So do whichever works for you.

Close.

The only difference would be if the room is warmed above its usual thermostat setting, in which case you'd have more rapid heat loss. In that case leaving the door closed would be (slightly) more efficient. But it's no biggie, do what works for you.

I used to do the same thing, but realized that having the oven on only warms up the room closest to the oven. It still using gas if you do it for an hour or more, so why not just turn the heat on and warm the entire house?.,,

I leave it open too. I have the ICM blower on my furnace to run in slow mode in the winter. Spreads heat evenly and continually throughout the house no matter source.....i.e. oven, windows getting full sun, etc.

To help heat the house, or doesn't it matter? Keeping it closed and the heat is still contained in the house but released slower, vs. having it open and the heat is released faster. Logic suggests better to leave open, but I'm not a thermodynamics engineer.

I always take advantage of that heat and leave the door open after use.

There is the same amount of heat whether the door is open or closed.

The only (significant) difference is in the timing. But if you warm the room above the thermostat set point, you would end up with slightly less useful heat with the door open. In that circumstance, there is more rapid heat loss (because it's directly related to the difference between the indoor and outdoor temperatures). The total amount of heat stays the same, you just lose it faster.

When I get up in the morning the routine is the same. Start the oven to 350. Grind and make coffee. When the coffee is ready so is the oven. Turn the oven off, crack the door. Enjoy first sips in a nice warm kitchen. I try not to overthink it.

Leave it open, and all that high temp air goes right up to the ceiling.

Keep it closed, and it warms the air at waist level.

Also-that really hot air transfers heat faster to the outside, so you lose efficiency.

Convection. Radiation. Conduction.

 

[Aredeeem]

Geez, I have a reversible ceiling fan in the kitchen, the heat from cracking the oven door goes everywhere and heats the entire kitchen. Can we agree not to agree on everything? My skinny arse likes it a little warm in the morning.

Nothing I read here is going to make me change what I have always done . It's like that for most topics .

 

[svtrit]

I thought I was the only one who did this!!!

 

[aquariuscsm]

I assumed he was talking about after use and the oven turned off . Just taking advantage of the residual heat .

My grandparents always did this

Interesting. How cold do you keep your house?

If I leave the oven door open my cats will eventually go inside and take a nap. They don't know that's unhygienic.

Tim Sample used to ask “if the cat had her kittens in the oven would you call them biscuits?”

I have to think closed is best. Not a huge impact, but I do believe, for first order modeling, heat tranfer is related to the square of the temperature difference. The bigger the temperature difference, the faster the heat transfer. So opening the door and spiking the kitchen temperature up means heat loss through the walls goes up higher. Leaving closed means it escapes more slowly.

But is it really a big deal? I don’t think so. Do whichever feels better. On a cold winter day I might to feel that warmth for a bit.

 

[PWMDMD]

Well unless the heat gets directly vented to the outside 100% of that heat is still being released into the house - just slower with the door closed vs the door open.

Dude , this is BITOG . Everything is a big deal ..
