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.

My dad has a stoneware "pig" hot water bottle its about 75 years old he uses it all winter. We used to get it in our beds when we were sick its the best bedwarmer you can get! The only damage that does is waking up the whole house when it falls out the bed!

Had you expelled the air before putting the lid on @Laptopsas ?

Yep, I was absolutely diligent about it. I heard a sort of hissing then a pop and the water was everywhere. The bottle hadn’t even broke down a seam, it was just a flap of the bottle torn.

I have to admit I think you posted this last year and I haven't used one since, because we have wheat bags (cherry stone bags BTW don't have the smell, and work fine - they smell nicer than rubber hot water bottles as well.)

But Confused two years? Since when has that been the advice? I am sure we used the same ones for decades running. My grandparents would always give us hot water bottles when we went to stay and I can't imagine they were buying new ones every two years. It seems incredibly wasteful to throw them out.

We always did boiling water if you had a cover on the bottle, or hot-tap water if it was an uncovered one. There were warnings on them saying not to use boiling water but my mum reckoned it was to do with scalding yourself when filling it and just to be careful.

The only thing I miss about the hot water bottle is the feeling of it - there is something about the pressure of water and the shape of it which isn't replicated with a bag. I don't think the cherry stones stay hot for as long either.

According to the safety guidelines

Apparently you should use kettle boiled & cooled water (as the minerals in tap water make them perish more quickly)

Use them with a fitted cover

Always check before filling that it looks ok & the stopper is done up properly.

Always let the excess air out.

Cherry stones sound like an interesting option though!

You’d have to prise my hot water from my warm, dead hands!

I have nerve pain in my feet and a hot water bottle on them is the only way I can get to sleep. I also have a long one that I use for back pain.

I know not to put boiling water in them so I’ll accept the small risk and keep using them. I use one at least 3 times a day!

AnxietySloth · 22/09/2025 00:43

Life is too short for this. You can injure yourself doing literally anything.

Used correctly, hot water bottles are pretty safe and very cosy. I also like heated throws. And the odd open fire. I live dangerously.

Ohnobackagain · 22/09/2025 00:37

Laptopsas · 21/09/2025 22:47

They’re not. A brand new one I had exploded, luckily all over the sofa and not on me.

Had you expelled the air before putting the lid on @Laptopsas ?

Newmeagain · 22/09/2025 00:36

I don’t use one very often but when I do I have always filled it with just boiled water! I thought that was the whole point…

This is a useful reminder about the risks as mine is a few years old now.

The bottle was six months old. What could it possibly have has done to it that would justify it exploding?

60 degree water can cause a third degree burn in five seconds. It doesn’t need to be boiling.

Then I suggest you contact the nurse and the advanced practitioner and tell them you know better than them.

Do try not to persuade them that heated throws aren't also dangerous though, or you might come across as a bit silly.

I don't find wheat bags hold the heat anything like as well as a hot water bottle.

We live in an old cold house and I use a hot water bottle for every bed in the house - it's part of my winter evening routine to put them in about an hour before bed.

It's important to check the dates, replace them regularly, not overfill or use boiling water and expel air. But that doesn't mean you can't use them at all.

I have a heated electric wrap (uses a tiny amount of electric compared to heated blanket and has an auto shut off too) and it’s great!!

SummerFrog25 · 22/09/2025 00:29

But she didn't say 'use them safely' & tell people what that involves, she just told people not to use them!!

If the water is cool enough not to burn you, it’s completely pointless to have the bottle.

Squeeze the air out and replace them every two years, sure, but they aren’t just leaking and bursting when used incorrectly.

Here, I'll put the bits you seem to be missing in bold...

"John Davies, nurse at Swansea Bay University Health Board - home to the Welsh Centre for Burns and Plastic Surgery, says he sees around 30 patients with hot water bottle burns every year.
"During the fuel crisis I think people will be using hot water bottles to keep warm rather than putting the central heating on. They are safe to use if you look after them properly," he said.

Janine Evans, an advanced practitioner occupational therapist at the centre where Ms Cowell was treated, said you should not fill hot water bottles with boiling water - and use cooled water from a kettle instead."

So no need to 'remind people not to use them'.

In the OPs defence, I'm in my 40s and only found out recently that hot water bottles have expiry dates, and that you shouldn't use boiling water in them. So there are stupid folk (like me!) who can find posts like this useful. Thankfully they're not something we really use anymore, and I've never used one for my kids, but it's still helpful to know for future, even if it is something I should have known years ago!

Remind people that they have an expiration date and that they need to be used properly, surely that's enough and better than banning them.

My 98 year old mum loved her hot water bottle, until a new carer put boiling water in it, it burned my mum's leg but not badly and thank goodness it didn't burst. Like anything, they need to be used correctly.

My mum has had to stop using hers as she can no longer do it up properly (arthritis) 😌 & it soaked her bed a couple of times very luckily she was in the habit of putting it in her bed while she faffed around getting ready ready for bed so it didn't hurt her .

Obimumkinobi · 22/09/2025 00:16

Surely this is the same as never drinking hot tea when holding a baby? No need to ban tea (or babies).

They’re safe to use as long as they’re within date. I popped into my local charity shop and saw some nice ones on sale - checked their use by date and all of them should have been thrown away about 5 years ago so I notified the manager and she threw them out,

Well done for letting her know & kudos to them for getting rid of them. I hope the company donating them hadn't done it knowingly & they were informed so they don't do the same again!!

SummerFrog25 · 22/09/2025 00:07

LaurieFairyCake · 21/09/2025 23:42

What dates ? I’ve had the same one since the 1970’s, seems fine.

I'd guess it doesn't have a date on it if made in the 70's.

modern ones perish quickly, my 70's one was good for decades! I only stopped using it as I went travelling & packed it up before I left & it's still in another country!

the newer ones aren't as well made & I think perish much more quickly. The dates on them are easy to find.

Clarefromwork · 22/09/2025 00:06

I have never heard of a hot water bottle exploding before but I do remember reading about mini chicken kievs exploding over someone when they were removeing them from the oven 🤔

I’ve just treated myself to a nice new hot bot today and I’m currently lying in bed with the leccy blanket on underneath me and the hot bot perched on my belly.

Clearly my demise is imminent.

At least I’ll die snug.

That's one thing I won't do, put a HWB in the bed with a plugged in EB, it's either/or

Hot water bottles don't leak on Mumsnet, they 'explode'.

Just as no Mumsnetter's microwave ever stopped working, they tend to 'blow up' as a rule.

Perhaps it's Mumsnet that's dangerous? 👀
