Keeping food hot for 12 hours

[EasternDailyStress]

DH has a job outside, where he used to be provided with a hot meal. Due to Covid, this is no longer happening.

I'm thinking that, in the winter, he could do with taking something hot to eat in the evening. We have a standard food flask, but ideally a lunchbox-shaped one would be so much better.

I've Googled, but can't find anything that fits the bill. Does such an item exist, and if so can you recommend me one please? Or any other suggestions for reheating food (he would have to do this in his car).

I can't think of any that would hold for 12 hours. 8 is about the maximum I think. Does it need to be a whole hot meal? You can get a car kettle that plugs in to the charging point/ cigarette lighter in the car which he could use for hot drinks, cup soup, pot noodles etc?

Camping stove?

I don't think there's anything that keeps food hot that long. Depending on what hours he works could he not eat a hot meal after 4-6 hours then have something cold like a sandwich later?

Just realised you said he would be in his car. So maybe not a camping stove.

We have one of these. I've never had to keep food warm for 12 hours though.

Thanks for all your suggestions. Looks like 12 hours was a bit ambitious! I was hoping there was something like a food flask but more of a flat shape, so you could keep things flat and therefore separate. Maybe there's a gap in the market .

He can already take soup in a flask, so maybe he'll just have to stick with macaroni cheese etc in the food flask, which stays warm for about 6/8 hours and just eat it earlier if possible.

Bloody coronavirus!

Purely from a food safety perspective, any food that's kept hot needs to be kept at 63C or above - bearing in mind that the food will get cooler as the day goes on. Any less and he'll be at high risk for food poisoning.

As well as car kettle you can get electric lunch boxes that use the car better too. Look on amazon under Electric lunch box.

Battery, not better.

I would take something warm in food flask for lunch so less time. Then cold plus a cuppa soup hot in evening made using car kettle

How about a cheepish insulted bento box inside a thermal lunch bag with a couple of those hand warmers shoved in the bag. Bet that would keep things warm.
Also the big Thermos brand king food flask have big wide necks big enough for pasta, stew, etc x

What about something like this?

How long is he away from the house? 12 hours seems a long time to then have to eat at that time.

Would it have to stay that long because you’d make it earlier in the day?

If so can’t he heat it up and put it in the flask later?

I’ve just been looking for one for my dd to take to school and the 710ml one says it keeps food hot for up to 14 hours it’s from Argos

Is it really 12 hours? Most would eat half way (ish) though a shift. Is he doing excessively long days?

Puzzled by the 12 hour requirement, unless he's working 24hr shifts or has a 6hr commute, neither of which seems plausible

A pre-warmed food flask should do quite a good job for a shorter time period.

Just to clarify, regarding the 12 hour thing, he often works a 3 hour drive away, so leaves at about 7. He's working til 11 pm, so has his teabreak about 6/7 o'clock in the evening. Of course, he could eat it at lunchtime instead, but often that break is very short, whereas the evening one is an hour.
