How often you replace hot water bottle?

I love my hot water bottle. And my dc do too. We use it almost every night. I've never read the instructions on the bottle before but it says to replace every 2 years?! Mine are way older than that! Do you replace often? Am i the only one who didn't know and doesn't do it?

I replace mine every few years, probably around 3. The rubber disintegrates inside so they may split if used for too long.

I've just bought a new one from Argos it is ceam with a chunky knit cover - do not buy one of these, I think the hole in the neck is too small, when you fill it, the water spurts out. I've stopped using it.

I've now bought a Superdrug one, it is blue without a cover, much better than the Argos one.

I've got the same blue one 💙

The rubber brakes down to the point they are more likly to burst/leak, and I don't want my kids being covered in scolding hot water, or even a bed covered in lukewarm water if it happens after it's cooled.

We only use them in the winter, so they get packed away with the thicker duvets April-October. Every other year I get new bottles to go in the covers, when I unpack the winter bedding. They cost £2, and sell them in supermarkets, so it's really not that arduous.

The £2 price point doesn't suggest a level of quality I want in a product that is keeping boiling water from scalding my body.

I do this ^ and I started doing this after two of our old water bottles leaked, one at DD’s bed, one at mine. Luckily it was just a drip so no hot water burns but it’s a wake up call We had them longer than two years, they looked ok so I wouldn’t go by look.
Covers are kept for more than 2 years if they are ok.

We just replace them when they start leaking.

If you don't over fill them and do squeeze the air out the top then there shouldn't be any risk of bursting. I've never had one burst in 40 years. I use one nearly all year as my feet are always cold.

stampedingcentipedes · 16/02/2026 11:18

I've had one burst on me and scald the back of my leg. I'm really vigilant about them now.

pinkpony88 · 16/02/2026 11:16

I had no idea about this! I’ve just replaced mine but the previous one was 24 years old! 😬 I only replaced it because the cover wasn’t as fluffy 🤣

@MIAMNER The wheat bags just dont feel the same 😔

Agreed, they have a dampness that I find unpleasant, and I don't like the smell.

I aim to replace my bottle every year. It's not a huge expense, and it's such a comforting thing to have if you're careful and don't overfill them/drop them. Nothing else eases period pain like my hot bottle water does.

Octaviathethird · 16/02/2026 10:56

My brother had terrible burns from one bursting, he was in hospital for weeks so I don't use them, it's not worth the risk.

Morereadingthanposting · 16/02/2026 10:45

Santa brings new ones in kids stockings each other year so that’s my cue to bin the old ones. He’s good like that! I always feel like I’m probably wasting money but don’t want to risk it. Saying that when we moved in with my mum during Covid she insisted on filling them all each night as in her eyes I clearly wasn’t yet a responsible adult to do so so maybe we are neurotic about them in our family!

ForPlumReader · 16/02/2026 10:40

Replace them when they start leaking or seem thinner.

GasPanic · 16/02/2026 10:37

Even if they are new they are risky and could go wrong. After many years of use even worse as they can perish.

Best avoided IMO. Yes the probability that they will go wrong is low, but if they do leak over someone the horrific burns are going to affect them for the rest of their life.

Or buy one of those plug in blankets that go over you and switch off automatically.

Sajacas · 16/02/2026 10:08

The rubber degrades and can break suddenly. Every few years or so there is a story in the paper of a small child with bad burns because people do not know they are supposed to be replaced.
It is one of those things- better safe than sorry. I would rather waste my money by replacing the hot water bottle than risk burning myself or a family member.

The thing that made me become organised about replacing old hot water bottles was one bursting and really burning my friend. She put it under her thighs on the sofa, the pressure made the water spurt out all over the skin on the back of her legs and burned her so badly.

It's a little thing but really important.

This is how it happens.

Also people pouring the water into it. Had one burn once where a child had poured boiling water in a hot water bottle and poured the water all down herself. It was nasty.

RedPony1 · 16/02/2026 09:52

i never remember to replace. but probably should!

Wheat bags are rubbish, they have a bad whiff (even the "scented ones") and don't stay hot anywhere near long enough

Theraffarian · 16/02/2026 09:45

I wasn’t super good at replacing mine until one burst in the bed . Luckily it was before I had got in , but still a pain to clean and dry everything. Primark have theirs at half price at the moment, picked up a lovely one with a faux fur cover for £4 last week.

As a nurse I’ve seen some awful burns from hot water bottles so please replace them.

I was an avid hot water bottler for as long as I can remember but I moved onto a heated blanket last winter and ditched the HWBs and never looked back.

I have to ask, what happens to them after 2 years? and is it at the stroke of midnight?

Do you set a reminder in your phone on the day you buy one so you can replace it in 2 years on the dot?

EleanorReally · 16/02/2026 06:24

although i am confused because if go to buy a new one it seems to say 2022 on it, so out of date already

EleanorReally · 16/02/2026 06:23

my intentions are to replace but i still havent
i love my hot water bottle

Idleplum · 16/02/2026 06:22

Sprogonthetyne · 15/02/2026 22:00

I used to keep them years but since the kids started using them, they've been replaced every two years on the dot.

Ours are much older than two years.
