AiBU to be angry with husband for slow roasting pork during heatwave?

[Prok]

I do my best to keep the house cool when it gets really hot. I do not cope well with heat. I make an effort to draw curtains, keep windows closed etc.

Come down during my lunch break and the formerly cool kitchen is now a sauna. Of all days dh has decided today is the day to use up the frozen pork for pulled pork sandwiches (dinner).

This after I told the kids not to open windows etc.

Dh doesn’t normally work from home so wanted a “treat”. I said it was an incredibly dumb thing to do. And I got called hysterical. And a nag.

Our oven only makes the kitchen hot when the oven door is open. For pulled pork you only open the door for a few seconds to take it out. I wonder if you have a problem with your oven? For me a slow roast joint which then needs very little doing to it makes way more sense than using the hob in this heat

The heat doesn't disappear though, so although the oven is insulated, the heat ends up in the room.

Claude can explain it better than me -

Your oven converts electrical or gas energy into heat. Some of that heat goes into cooking your food. But even that portion doesn't disappear — when the food cools down on your counter, it releases that heat back into the room. The rest leaks through the oven walls and door immediately. When you open the oven, another blast goes straight into the kitchen.
So 100% of the energy you put into the oven eventually becomes heat in your living space. None of it escapes — unless you open a window, in which case some convects out.
The same is true of almost every appliance — your fridge, your TV, your lights is just adding to the thermal load of the space.

No they don’t, they follow public health advice not to heat their houses

This would be studied by scientists if true..an oven heats the room it’s in ..basic physics

You are definitely being unreasonable, however you are also reacting how I would in the same weather 😂 so cut him some slack, even if he was thick

All of the heat that the oven produces ultimately ends up in your room. It doesn't disappear unless you had some kind of fancy extraction / heat change system I suppose.

ETA you only notice it when you open the door. The rest of the time the impact is small over a long period of time,

Because….scientific fact ..physics …as confirmed by public health advice for heatwaves

We don’t have anything fancy. The oven only heats the kitchen when the door is open. We roasted a chicken yesterday to have with salad and it honestly didn’t heat the kitchen

…and all the excess deaths? Just a joke? The strain on our public services?

As someone who also doesn't do well with heat YANBU. I won't even put the hair dryer on when it's like this 😂

A hot closed oven is heating the masonry, floor and air around it by a small amount and that in turn raises the temperature of your room. You may not feel it, but it does heat the room up.

The laws of thermal dynamics dictate that it is true -

First Law — conservation of energy. Energy can't be created or destroyed, only converted from one form to another. So every joule of gas or electricity you feed into the oven has to go somewhere — it can't vanish. It all ends up as heat, eventually, in the room. This is why the "does it make the room hotter" answer is an unambiguous yes.

Second Law — entropy always increases. Heat naturally flows from hot to cold, never the other way round without work being done. This is why your oven heats the room and not the reverse.

Whatever the laws of thermal dynamics etc say, I can only repeat that roasting a chicken did not make our kitchen hot last night. And it was really hot here.

DH decided that the belly pork in the fridge should be used up. He did a simplified version of The Keith Floyd Cassoulet. No goose joints. It was rather nice.
A minor bonus was that he sharpened all the knives.

I'd swap a cool kitchen and no pork for a hot kitchen with pulled pork any day 🤣.

Laugh about it and move on!!

Could be worse. He might have put the heating on to dry the washing

It’s already a sauna so enjoy the pulled pork 🤷🏻‍♀️. At least you won’t need to cook

Someone else is cooking on a very hot day and will hopefully clear up afterwards.

Take the win, return to your cooler room or run a fan on you, up your fluids and put your feet up and relax!

You should really let someone know that your kitchen doesn't obey the laws of physics 😂

I am not suggesting your room would have been noticeably hotter but over time (over a number of hours) your room would end up a bit hotter than it would have been if you hadn't had the oven on; like a degree or two, not suddenly scorching.

Either way, as you can see, the official advice is not to have ovens on when it's hot. This is why. It makes a difference.

Yes but as pp have said, the impact is small
over a long period of time. So although physics and government advice say otherwise, in practice it doesn’t make a huge difference. Not so huge that we shouldn’t use the oven. Or cook at all. I agree that hot heavy food is not appetising when it’s hot, but pulled pork seems ideal, particularly as the oven is at a relatively low temperature. Although I do agree with those who say pulled pork in a slow cooker is best 😋. As is pulled chicken breast

If it's a big enough piece of pork to serve cold or in stir fry tomorrow and the next day he's done you a favour.

I love that your username is an anagram of the offending meat. That's all.

ok so not noticeably hotter - which takes me back to why the OP’s kitchen IS noticeably hotter. We got more heat from the chicken itself than from the oven itself over the hour and half it was roasting. I’m not arguing with anyone, just stating what we have experienced.

Bit of a sexist assumption that cooking is OP's responsibility.

Do you think men only cook as favours to their wives?

YABU - go into another room 🤷🏼‍♀️

Ah bugger. I have a slow cooker meal planned for Wednesday. I don’t want that going in the house. Could I use an extension cable and plug it in in the garden (in the shade)? (Only half joking)
