How long does water stay cool
22616
We generally add ice cubes in our packs when we fill them up to make them stay cooler longer. Plain ole water will stay slightly cooler outside than if it was in a bottle but does get warm because of the sun and your body temperature in a few hours.

The hydration bladder and the pack itself is not insulated, so it is like having a water bottle inside a normal backpack. The bladder is in the main compartment which is up against your back.There is a little padding in between, but not that much. Water inside the hose in particular will get warm pretty much right away in sunny weather. Water inside the pack will generally stay cooler.

I have never had water in mine last more than an hour, within an hour its stay cool.

Varies. One example: about 97 degrees, water fresh out of the store fridge, stayed cold about 20 min, still cool just over an hour later, still refreshing enough 1.5 hrs later, and then I ran out and refilled. But - that's one of the reasons I bought me a small one like this one!

Your body heat and outside temp will affect mainly obviously and water temp to start with but probably 1/2 hour to an hour for cold.

You got to pack some ice in it if you want it to stay cool for more than one hr

Cool and after a 8 oz glass it needs re cool your water which takes time.. Hope this helps.

It doesn't take long at all to cool. Once you wet it, it immediately starts cooling. Yes, it feels cold and the cold lasts for several hours or as long as it's wet. I used mine inside the house next to me for hotflashes and it was really cold. I haven't tried to use it outside yet though.

They will stay hydrated as long as they have water, for up to about a year. Changing the water to avoid contaminants from clouding the water is necessary. If they are exposed to the hot sun for an extended time they will turn to mush.

Right now the temperature where I live is 90 degrees and this tends to be desert-type country. I can water for about a week at the most in these conditions. Earlier in the season I could get almost 2 weeks.

About 8 minutes, depending on your coolant temp and flow rates, of course.I usually make 5 gallon batches, which cool from 210 to 78 degrees in about 4 minutes. My coolant water is about 60 degrees.After use, I flush with clean water then run some sanitizer through and let it drain out. I've used about 10 times so far and it works great. I'm considering installing quick connect fittings as connection of the hoses each use it the only thing that takes any significant time, but even that is not much.

My husband fills the thermos 1/3 to 1/2 full of ice cubes followed by cold water, and 10-12 hours later when he gets home, some of the ice still remains, although the cubes are smaller. His water stays cold the whole day.

Yes. I use mine just for water and it holds the cool temperature for quite awhile.

It will last app. 12 hours on a tank, the nice feature of this cooler is that when it starts getting a little low you can use the built in timer, from 1 to 4 hours. This thing is worth the money.

The coldness depends on the water temperature. However, even room temperature water works well. The cooling should be immediate.

No, it stays cool because of the air! If it does get warm, just let the air out and put fresh cool air in.it, takes just 2 mins.

It depends upon the outside temperature and the temperature of the water when you add the ice. The manufacturer says 18 hours and I have had it last that long in my air conditioned home. I have had it last 24+ hours in the fridge. But, in warmer settings, 6 -12 hours is more realistic. To maximize the time, start with a cool bottle (running cold water into it or even keeping it in the fridge). Then, use ice plus COLD water from the fridge (otherwise the warm water will melt the ice before the outside air gets a chance). Then, try to minimize time in direct sunlight. Using a room temperature bottle, plus cold water and only about 4 ice cubes, my bottle keeps at least some ice for the entire 10+ hours of my commute plus workday (desk work).

I would say at least an hour. I'm always done with mine before it gets cool. I use it for my coffee too.

It is not that simple. They may stay cold in a good cooler all day, on the table maybe an hour, but on a hot swollen joint maybe 15 minutes. You want cold packs to transfer heat quickly so that they cool things. A better question is how much heat can they absorb? I put it in a cheap cooler with a liter bottle of water that starts at room temp. The bottle of water cools to about 50 degrees after a couple of hours and lasts about 5 hours. Being segmented it has more surface area and transfers heat faster than a solid pack. The solid pack stays frozen longer, but the water does not get as cool. It is not that simple.

Our son takes his funtainer bottle filled with water to school and keeps it on his desk to drink throughout the day. These bottles are amazing- I wash the bottles and while they are still wet I place them in the freeze the night before and in the morning we fill it with water and/or milk for his lunch box. It keeps his water/milk cold for about 6- 8 hours. Milk/water does stay very cold. It does sweat a little, so his teacher usually places a paper towel under it. We have used these funtainer bottles for 3 years and are very pleased with the results. Hope this helps:)

It will keep the temperature for days. One day you will find your water orange though. It rusts. I definitely think this is a waste of money product as it went to the trash after 3 months.

It's as cool as the water you put in it, as far as my experience goes..it definitely is not warmer.
