Useing the water from hot water bottle again for next night's bottle

[tellmewhentheLangshiplandscoz]

This is ok isn't it? As in empty all 4 bottles worth into the kettle, boil them fill bottles again? I'd be sure to empty the kettle before using it for cooking or making a brew

In milder weather I'd just empty it into my hanging basket or garden pots.

Seems such a waste otherwise

Yeah it's fine!

i do this

I'm glad you asked this OP! Was wondering myself as I worried something dire (no idea what!) might occur in the kettle!

I used to then somebody said about there could be plastic residue from inside the hot water bottle into the kettle. Since then I stopped and used it to water plants in the house etc

As a student I used the hot water bottle, water to wash in the morning, smelt of rubber all day, lol

I wouldnt. It could make the kettle water taste rubbery afterwards. It probably wouldnt but I couldnt risk it!

Bits of rubber sometimes come out of my HWB and I wouldn’t want that in the kettle I use for drinks.

I would want to rinse the kettle out a couple of times if it had rubbery water from hot water bottles in it. And that would defeat the object of re-boiling it in the first place.
Why don't you get microwave hot water bottles? (I don't know what they're like as I don't have a microwave)

The water smells rubbery to me so I wouldn't. If I had a dedicated pan, rather than a kettle I might.

Have you figured out whether this is really much of a saving or not? My understanding is that cold water remains pretty cheap (at least for us it does, we're based in Germany) and we pay a flat monthly rate that isn't use depedent.

I guess if you're on a metre this helps...although i suspect something microwaveable would be more cost-effective in the long run.

I did this until the kettle started smelling a bit rubbery. Now I use the water on the plants when possible.

Yes I was thinking Cholera or something 😂

Pour it down the loo to flush it
Tip it into a bowl to use for cleaning
Rinse the shower/sink down with it

I wouldn't do this as it would be really difficult to get the kettle properly clean again. The water would have lots of microplastics in it and the material of a hot waterbottle isn't food safe, you'd need to rinse out the kettle several times to get rid of the traces of rubber so that would be more water wasted than if you just threw the hot-water-bottle-water away. If you have any limescale in your kettle that's even more difficult to clean, as the rubber particles will cling to it.

If you really must reuse it then don't use the kettle. Use a saucepan because that's easier to scrub clean after having been filled with non-food-safe water, as compared to a kettle. But it still needs cleaning so you'd still be wasting water unless you would be washing up anyway.

Tip into a jug, microwave it?

I wouldn't tip in kettle, the water just smells of rubber, you'll waste far more cleaning the kettle out

Ok so I think the rubber smell/bits is a good point.

Last few weeks I'd been tipping it into washing up bowl so may just continue to do this.

My DMum does this.

She has a separate kettle for it (uses hop) because yes it does fur up over time

It's a bit of an eye-opener, because it's a demonstration of how substance leach into water, and can be redeposited under certain conditions

I've debated putting it back into the kettle but scared it would ruin it. Now I leave the hot water bottle in bed to stay warm while I take the dogs for their morning run and then use it to wash their muddy feet

I imagine you'd end up with rubbery tasting water over time even if you emptied. It's such a tiny amount of water though. Is it really worth recycling?

It will make your kettle taste of rubber, trust me .

Lots of tiny actions really add up.

Just think how much the saving would be if every household used just 1litre less water a day

That's over 28 million litres every day - a saving worth having

@GlacindaTheTroll but surely you'd need to rinse out the kettle at least once with at least a similar small amount of water?

I thought you meant pouring hot water bottle into baby bottles for milk. I thought you had gone mad!

My DD has a warmer that I microwave. No water.

But if you did it you wouldn't do it just once would you? So would you end up with month old water being tipped back and forth or would you draw the line somewhere?

I expect a hot water bottle spends a lit of time in the warm zone where germs breed and I wouldn't fancy it.

If it was warmed up in an old pan used just for this purpose then I guess it wouldn't matter if it was a germy soup.
