To remind people NOT to use hot water bottles?

There is another thread running about cold weather and hit water bottles are being recommended as safe. They are not.

Get a heated throw or the microwaveable bags.

If you must use one, don’t use boiling water.

Hopefully your parents weren't neglectful and that you aren't scarred.

Thank you, no my parents weren’t neglectful and I wasn’t scarred. I was filling it from the hot tap in the kitchen.

Indeed. I don’t know how I came to be doing it 🤷🏼‍♀️

Children should never fill up HWBs.

I would always have rolled my eyes at this sort of post in the past, until my HWB exploded and gave me huge scalds on my thighs a few years ago. My own fault for using too hot water too many times but I never thought it would burst. Now I use an electric underblanket.

Because they’re as safe as houses

Seriously ... this is 'nanny state' advice IMHO; the sort of thing that denigrates people's common sense. The only time I would suggest someone not use a hot water bottle is if they have learning or physical difficulties in case they might inadvertently hurt themselves.

Nail on the head.

Similar to the "advice" never to use warm water to defrost car windscreen. I've been doing it for 40+ years and never broken a windscreen yet. Common sense says to use "warm" water rather than boiling hot.

Far too much nanny state these days which makes people incapable of thinking for themselves, making things worse.

Rubber hot water bottles have only been around for 100 years or so and every year there are well publicised stories of them exploded and causing severe burns.

Anyone with half a brain and common sense knows not to use boiling hot water, so even if it bursts, they won't get burned!

Indeed, risk has been removed from our lives to the point of absurdity.

Once upon a time, people looked both ways before crossing the road.
Now, if they get hurt, their first thought is "who can I sue?".

Agree. The wheat bags are so much better, safer and easier to use.

I used wheat bags until we got an infestation of little bugs which the pest controller traced back to a microwaveable wheat hwb. Never again.

I use a hot water bottle now but one did perish and burst in the bed a couple of years ago, scalding my ankle. So now I’m very careful never to use boiling water and also replace bottles every 3 years. The rubber does perish over time and people keep hot water bottles for decades for some reason. They are actually pretty cheap to replace!

I worked as a carer and went to one of my visits to find him microwaving a hot water bottle with boiling water in as “it wasn’t hot enough”
I asked him if he wanted lava instead!

Hotwater bottles. I have fond memories of my hot water bottles. Car shaped ones etc. it should be obvious not to fill with boiling water! Who would? Doesn’t make sense. Hot does not mean boiling otherwise they would be called boiling bottles wouldn’t they? As mentioned you don’t fill them to the brim. Less than half full. You make sure there is no airspace left before you screw them shut. In a non heated bedroom with ice inside the windows which as children we marvelled at the ice patterns yelling Jack Frost has come! We loved our hot water bottles. It was and still is a winter delight. Improper use of anything is lack of common sense. How can a hot water bottle explode! Overfilling it and leaving the air in. Would you climb a ladder when nearly vertical? Would you hold a sharp knife by the blade? Would you not use a fire guard with young children around? Would you automatically down a drink of tea without taking a sip to test it first? Then there are chip pans, falling asleep with lit cigarette! Walking around with knives in your hand? Who remembers to point the blade downwards? You don’t? Not leaving saucepan handles hanging over front of cooker when full of boiling food! Do we ban saucepans! These days risk has been removed from our lives and there is no awareness of the dangers in life. Just look before you leap! Remember that one! For those who have had exploding hotwater bottles, stop putting in explosives! (Boiling water)

I was in Boots the other day and remembered this thread, so I looked at the hot water bottles on sale. Every one was dated 2022. So is the advice 2 years after manufacture (in which case all those bottles should be thrown out) or 2 years after you start using it?

i saw the same
confused

Cherrysoup · 27/09/2025 21:30

Found out that the hot water from the tap in the bathroom is hot enough. I unfortunately didn’t put in the stopper properly the other night and it leaked (warm) badly. User error.

I have one of those rechargeable ones that are filled with some kind of gel. I'm sure someone will be along to tell me how dangerous they are but I love mine, it eases my aches and pains and stays warm for hours.

Can you recommend which one please.

Then you’ve been very lucky. It will only take one bursting for you to not find it silly.

It makes me sad that mumsnet got rid of the laughing reaction - the only suitable response for posts like this 😂

You’d have a fit in the Netherlands then. They put (metal) hot water bottles in babies’ cribs for the first week of life/until the baby has learnt to regulate their own body temperature.

I love a good hot water bottle but even we didn’t follow that advice.

CommentHere · 27/09/2025 19:48

We use the electric hot water bottles as the are so safe and gorgeous and warm.

We have traditional HWB too and leave a little cold water in the end before filling with water from the kettle. I believe there is more danger in the filling of HWB than of them exploding. I know 2 people who scalded themselves filling the one inch wide neck of the HWB, it's not like filling a flask as the HWB won't stand on its own.

Mjin · 27/09/2025 19:08

And not remotely hot!

What? Nut allergy anaphylaxis can cause death so of course biscuits are labelled for those who are so sensitive that cross contamination could kill them. That’s really not the flex that you think it is.

I didn't say biscuits, I said packets of nuts. A packet of nuts labelled 'may contain nuts'.

applegingermint · 25/09/2025 14:50

CaptainMyCaptain · 25/09/2025 07:38

We are living in a time when people apparently need warning that coffee is hot and a packet of nuts may 'contain nuts' so I wouldn't necessarily blame the hot water bottles.

Perhaps the quality of manufacture is poorer than years ago and that is why there is now a problem.
