how hot can the water be that you put in? how long does it stay hot (or at least warm)? thank you!

My daughter received this hot water bottle from us. She says she has put the hottest water from the tap and then hot water from the tea kettle into it. Hot water from the kettle is too hot to put in by itself. She reports that approximately 45 minutes later, it is at least warm. Enjoy!

I use boiling water and it stays HOT for an hour and warm in bed another hour

I took it camping...filled with near boiling water. It stayed hot/warm for about 4 hours in my sleeping bag.

Also, I never use the pouch because the bottle is not very hot using tap water and the pouch prevents what little heat it has from getting through to my skin. One layer of clothing is sufficient.

It says only hot tap water. On a couple of occasions I have heated the water a little more than that because the tap water just isn't hot enough in the bottle. I use mine on my lower back while laying in the recliner and it seems that my body heat keeps it slightly warm for a long time, even hours, but it's not enough warmth to be therapeutic. I don't fill it more than 1/3 full when doing that, though, as it's not comfortable to me when it has more water in it.

It is all dependent on how hot your water is. With hot tap water, it stays *hot* for 30minutes or so. Then it is just warm.

Pretty much what everyone else said. I use mine to keep warm water (ie: warm not hot) for drinking. I'd say it loses between 25% - 50% of the heat over a period of 24 hours (depending on how often it's opened and how much is consumed). Still a good product.

The water stays hot for quite a while. I use it to have boiled water for the baby formula. Then cool it for the next day. I love using it for having water for tea better than the microwavve. Hope this helps.

It should get hot because its boiling water but keep an eye on it you don't want it to get extremely hot, it may burn thru the plastic

No it doesn't keep the water hot, but it is super fast at boiling the water. I love mine, I use it all the time.

It stays hot for as long as any water that has been heated. It doesn't maintain a temperature.

Yes, we heat our water to a comfortable temperature, maybe just a tad bit warmer. I'm not sure what the maximum temperature would be for water, I would think whatever the plastic piping would take, presumably up to boiling? Hope this helped. We really are sold on our ZODI. One 5 gal bucket of water will give you more than enough to take a shower.

I don't think it maintains it at all really. If you put in hot water it seems to cool off as quickly as it would in a bath. Definitely won't stay warm for a long time but okay for a 10 minute soak.

I've put warm water inside, but not hot. Not sure about the toxic part though. Hope this helps!

We have had ours for about 1 1/2 years. The housing gets a little warm, but, never hot. If we don't use the water for awhile, the water will be warm until it flushes out. Hope this helps.

I don't think hot water would work well in it. It's insulated with a rubber material. I'm not sure but I can imagine it melting? I would try a reusable microwavable heating pad instead.

I get mine a little wet. wrap in towel put it in for about 3 to 5 mins or longer if you want it hotter.

The heat is automatic, but if you put cold water in it, the heater is not strong enough to heat up the water. Even if you put warm water in it, the heater only keeps the water warm for about 20 minutes and then it begins to turn cold. So I would say that you can just put the cold water in it and the heater is not strong enough to actually heat up the water.

Each "pass" through the heater element (where the flames are) raises the temperature by a certain amount, I would guess about 40 degrees. So if you put water in that is, say, 50 degrees, it will come out at 90 which is a little cool for a shower but not uncomfortable. If you run the water back into the container you originally pumped it out of, it will get up around 130 degrees, which is too hot for shower but OK for dishes. However, it's a gradual process and depends how much water you have in the original basin. What I do is to run it until it is comfortable and then turn off the flame but leave the pump running. I would probably not start with warm or hot water from a tap, just like I wouldn't cook with such water, because by sitting in the pipes or hot water heater it has dissolved sediments and chemicals in it. The colder the water, the less sediment/chemicals in it (except for gases like oxygen). So to the extent that you want to avoid getting corrosion build-up in the heater element it would be best to start with a colder water. However, there is no problem running water of a warm temperature through the heater element, per se, though eventually it could get so hot it might melt the plastic tubing or something like that. By then it would be so hot you couldn't even touch it. Just pay attention and you'll get it just the right temperature.

depends on how cold water is, but it wasn't unusual for me to get a good 2-3 hours on medium. It gets very hot out of the water, so be careful

The water doesnt ever get hot unless I add it hot. Maybe mine doesnt work like it is supposed to, but it has never heated the water.
