Shirley O. Corriher, in her recently published book Bakewise, says that the
The design is perfect for cooking. However, it is hugely energy inefficient to keep the oven door open when the oven is on. And for gas ovens, doing this can lead to a build-up of carbon monoxide, which can be deadly. It's just a bad, bad idea,” he adds.
Opening your oven door can make the temperature of the oven drop dramatically. In fact, the the internal temperature can drop 25 degrees.
By opening the door, you do allow the heat to escape much better, but still, it wouldn't compare to a small electric infrared heater. If, however, you have baked something, and want to utilise the residual heat in your room, then absolutely.
By keeping the door closed you help regulate the gas release and the level of heat in the oven itself. Cold air being let into the oven makes it cool, causing uneven heating. So just keep an eye on it through the oven window and only open it once it's mostly set.
If you open the door during this crucial baking period, cold air rushes into the oven and disrupts the rise of your cake. The rising batter could contract and collapse, producing a cake that sinks in the middle. Wait until the end of the cooking time to check your cake and test it for doneness.
No it's not okay to cook with the oven door open. The door traps the heat inside of the oven. Leaving it open won't allow the oven to reach a high enough temperature to cook your food.

She advises: 'Instead, you should only heat the room you are in and close doors. By having doors open, heat is lost more quickly and will also warm up an unused space, which adds needless money to energy bills.
There's no set rule, but in general, keeping air circulating around your home will help to keep the temperature down. Opening internal doors and using a fan will encourage good airflow. It's especially important to keep your bedroom door open if possible, to help you sleep.
It Could be Leaving Through the Front Door
Similar to your windows, around 11% of your heat is lost through your doors.
Booming sounds (like, say, a slamming oven door) can cause vibrations that affect the outcome of your cake. Of course, most baked goods aren't sensitive enough to respond negatively to regular kitchen noise.
The temperature of the front panel can be up to 60 °C higher than the room temperature. For instance, with a room temperature of 20 °C, the panel may be 80 °C hot. In the case of the oven's glass panel, the temperature can be up to 65 °C higher than the room temperature.
Yes, opening the oven door will cool it down. Although it's advised to keep the oven door closed while cooking, opening it can help cool down since half of the heat will escape, allowing the temperature to drop faster.
Opening hot doors
Doors that are very hot to the touch or have smoke billowing through the cracks will more than likely have a fire on the other side. This means that the door is actually holding the fire back and opening it would only allow the fire to spread.
When approaching a closed door, feel the handle with the back of your hand for heat. Then, feel the door starting at the bottom and move up to the top. If the door is hot, do not open it.
'Having better airflow from the door being left open can help your bedroom have a more even temperature with the rest of the house/apartment, allowing your thermostat to respond and keep you cool for good quality sleep,' explains Dr. Jade Wu, PhD, and Mattress Firm's sleep health expert.
This is the system which provides air conditioning and heating. In order for it to work efficiently, air has to be able to circulate within the property. If doors are kept closed, even in unoccupied rooms, the air is not able to circulate freely.
Especially with central air, closed doors and vents only obstruct the blower fan and ventilation, which leads to balmy, hot air. Closing a door unbalances the system, causing pressure changes and air leaks. Open vents and doorways help keep air flowing and your home cool.
It's a common misconception that closing off some rooms in your home will reduce the amount of space you need to heat or cool, thus lowering your energy costs. In reality, closing doors and vents in unused rooms can actually increase your energy use.
Why can't the oven door be opened to heat the kitchen? The broiler and oven burners are designed to burn with the door closed. Opening the oven door disrupts the air flow pattern, and high concentrations of carbon monoxide may be produced.
Don't open the oven door until the cake is almost cooked
If you allow cold air into the oven the cake is likely to collapse, you need to wait until it's properly set before taking a peek. Similarly, when you're putting the cake into the oven, don't hang about and let all the heat out.
Food crumbs and spilled liquids on and under stoves and oven can attract pests. Make sure your gas stove and oven is in good working order and vented directly outside. If the gas stove and oven is not vented outside, open a window when cooking. A fan in the window can help vent gases.
Now don't flip out on us, but you don't always have to flip your food. When roasting items such as French fries and veggies, pre-heating your cookie sheet eliminates the need to flip halfway through. This method isn't suggested for baked goods like cookies (they wouldn't look so pretty).
Your oven is hottest around its periphery: sides, bottom, and top. The closer you get to those metal walls, the hotter the air. Thus anything baked towards the periphery will bake and brown more quickly than anything baked in the center of the oven.
