Will it insulate/be functional for heated beverages? If so, for how long?

http://polarbottle.com/ Click FAQS link for the following info: The Polar Bottle Thermaluxe performs the best for hot liquids. According to our tests, in a standard mug, water at a rolling boil (201F) at 5,430 feet above sea level will drop to a temperature of 118F in about a half an hour. In the Thermaluxe, on the other hand, the water took five and half hours to drop to 116F - an impressive 11 times longer than a standard mug. Hope this helps. Cheers!

Didn't try it with hot beverages, but it doesn't keep things cold very long.

It's decently insulated. It would keep food drinks cool for a couple hours without ice I'd think. We use cooler packs a lot which are nice because they don't melt

Couple of hours. Of course coffee gets cooler over time - still warm after 3 hours but not hot. Mug is well insulated and works about the same as other double-walled aluminum insulated mugs.

It odes better keeping liquids cold but if it is full to the top it should keep liquid warm for a couple of hours. As long as it isn't in freezing weather like we've had.

Yes and a good thing too, it's not insulated so hot beverages go cold fairly quickly.

Possibly for short periods of time, depending on outside temperature as long as their is ice it should work. Based on my experience I would not expect this cooler to keep something frozen for more then 1 to 2 hours in a very hot environment.

The purpose of the inside cup is for insulation to keep liquids cold without sweating on the outside. I have not used my cup for hot beverages as I prefer not to sip hot beverages through a straw. But it just might work for hot as well as cold. Hope you enjoy it.

The container is plastic and not insulated. I think Thermos makes a stainless version that may better serve your need.

i havent used mine for hot drinks , and would probably avoid anything HOT HOT . one of my coworkers also has one , and said it got screwed up when he put it in the dishwasher instead of hand washing it , so i would think anything HOT HOT would ruin it . . but if its just really warm , it should keep it warm for quite a while .

Similar weather to where I am. It will get cool in about 2 hrs. If the drinks are cold going into unit they will lose some coolness within first hour then be maintained at that temperature until around 2 hrs when they start to really cool down. Long trips or short stops will keep it all KOOL

This would be fine for hot drinks, although I do like my beer cold in a frosty mug!

no, but it might take quite a while. I put water in it and it took about 20 minutes to get what would be just warm. I haven't tested its Temperature-over-time/liquid.I'd do it now because you have me curious about it, but the unit self-destructed within weeks.

The mug will hold up to heat and the handle remains cool. However if your knuckles touch the outside while holding, it'll burn. I tested with spiced cider.

Agree with many other responders -- stays warm for maybe 8 hours -- but definitely not hot after that. Insulation is present, but it's not like a thermos at all.

It'll get warm fast, best used with bourbon. Wouldn't suite beer but is great for bourbon and just adding to a glass of diet coke, lasts longer that way too

Its not insulated at all. It will only stay hot for about the same amount of time it would in a regular coffee cup.

Your question is ambiguous. If you mean "Does the heater turn off while heating the beverage?", the answer is no. It will keep your beverage warm until it dies.If you mean "How long before it dies?", it's about a month. Read the 1-star reviews.
