I know this is a joke etc. but anyone unaware of this, that would not do anything. The valve only stays open when it is hot, hence you have to keep pushing the button for a while before you can let go. These safety features are really old.

That’s not at all true, or at least not something you can rely on as general advice starting with “push the button” even.

Maybe on a newer model somehow? But how does it get hot if the gas is not on to start with?

My old gas stove would kill you if you turned the knob without lighting.

It’s been a EU-wide requirement since 1996, but the law was actually introduced in 1990 with a 6 year implementation period. Even before that many EU countries already had national regulations that mandated this. So your stove has to be at least 30 years old not to have this safety feature. Personally I have never seen a stove without it, and I’m in my mid 40’s

Also stupid not to add it, since it’s a very cheap and reliable part to include.

But how does it get hot if the gas is not on to start with?

To turn it on you have to keep the knob pressed (this usually also triggers the sparker), this forces the valve open. Once the burner is on for a few seconds you can let go and it’ll keep burning. If the flame ever goes off (e.g. your pan of pasta boils over and the water extinguishes the flames) the bimetalic part that keeps the valve open quickly cools down and shuts off the gas.

It's a failsafe system. Gas fireplaces have something similar. Prior to being lit, the pilot/valve has to be held open manually. While holding it open, the ignitor can be used to light the gas. Sometimes this is simultaneous (opening & lighting), while other times it's two separate mechanisms. In either case, when the gas is lit, a device known as a thermocouple keeps the gas valve held open as long as there is heat. There are electrical and mechanical varieties. If at any time no heat is detected (or the thermocouple fails), then the valve is closed.

Fireplaces need regular maintenance and sometimes a thermocouple fails because it's dirty.

I guess my oven was too old for that tech

[–] BorgDrone@feddit.nl 1 points 3 hours ago

If it’s a gas oven, then probably. I remember people having gas ovens when I was a kid in the early 1980’s, but I haven’t actually seen a non-electric oven since then. It must be at least 40 years old by now.

Huh, I didn't know about that.

[–] BCsven@lemmy.ca 9 points 12 hours ago (1 children)

Don't rely on the interweb guy. Plenty of stoves still pour out gas if you open the valve.

[–] GreenCrunch@piefed.blahaj.zone 6 points 12 hours ago

Damn, there go my weekend plans to leave the stove on.

Most stoves in North America are electric/inductive anyway.

Anecdotally I see gas burning stoves a lot still in NA. I think there’s a culture that they’re “better” than resistive or induction stoves. Though that could just be local to my region, I’d have to look at the stats

[–] BorgDrone@feddit.nl 1 points 3 hours ago (1 children)

Induction is great, but resistive electric stoves are practically unusable

[–] anvilskinner@sh.itjust.works 1 points 1 hour ago (1 children)

I mean I don’t agree with that. I’ve majority used resistive stoves my entire life and I think once you get used to the fact that it’s takes time to adjust heat, you get used to it. But yea I’d much prefer induction if I could have it. I have an induction wok thing and cooking with that is great, instantly getting different heat levels is nice.

[–] BorgDrone@feddit.nl 1 points 1 hour ago

I learned to cook on a resistive stove as a kid and it sucked donkey balls. Cooking on gas when I moved out for college was such a revelation. Induction is even faster as long as you don’t get an induction hob with those stupid touch-screen controls.
