How long will this mug keep coffee hot?
1604012
I use this mug for everything hot and cold, but mainly for hot water. I drink a lottt of water, so I usually finish them very soon. And I like hot water all the time, especially morning when I get up, which would be the longest time for water kept in my mug..lol-- the whole night time, still keep warm.))

These keep drinks piping hot for hours. I'm not exaggerating when I say at least 8-10. You have to make sure you don't put it in super hot or it will not be drinkable for hours. It's that good.

Your coffee machine must brew cold coffee. If I don't open the lid, my coffee is still scalding hot after at least 2-3 hours. Locking is not necessary. Or you might have a defective mug.

This really depends on how much coffee you put in and how fast you drink it. The more hot beverage you have in the pot the longer it will stay hot/warm. I have found that if you put boiling water in the pot first to warm it up while you are making your coffee, then fill it 4/5th (two 12-cup pots), it will last hot for about 5 hours and drinkably warm for another 5. It also depends on how hot you like your coffee. My mum like it scalding hot so she doesn't like these things. Me, I am fine for about 6-7 hrs, then I need to microwave the cup to reheat it. As others have said, you can still find warm coffee in the pot the next day 18hrs later, but it is too cool for my taste. This really depends on how much coffee you put in and how fast you drink it.

The beverage stays very hot for 2-3 hours. It will begin to cool down, but is still quite warm after the 3 hours. If you keep the lid in the closed position, it will stay very warm for a couple more hours.

The surface temperature of the plate fluctuates from 210F-247F, measured with an IR thermometer. Note that this doesn't mean will keep your coffee that hot because your coffee & mug are losing heat through the sides and top.

It will keep the coffee hot for several hours -- preheat it with boiling water. I bought a steel thermos which works a bit better. But the carafe is good if you plan to drink it all in less than 2 hours.

I have used mine for Hot chocolate and it kept it hot for longer than a regular cup. Try putting HOT tap water in it for about 2 minutes before you put the Coffee in and it should do the same.

If I prime the cup before putting hot coffee in with a small amount of boiling water (as I'd do with any double walled container) it will keep hot coffee hot for the better part of a work day. Not piping hot, as it does lose a lot of heat through the lid, but it's hot until lunch and warm in the afternoon. However, I'd put ice and water in mine and let it sit over night and gotten up the next morning to still have ice in the tumbler. (This is all to say, yes much longer than plastic, especially if you prime it with boiling water first.)

Having never owned the stainless steel one I cannot compare them. But I can tell you that this model will keep hot beverages hot for at least 4 hours or so.

I like my coffee hot so after brewing I put the mug in the microwave for 40 seconds and it's fine. have not tried it for the full 2minutes to boil cold water.

If the mug is heated first & you keep the lid closed, at least 4 - 6 hours. Here in Montana in the winter, it is closer to 4 hrs. :)I have opened the cup at supper & the small amount of coffee left in is still warm.

The biggest flaw I found is that the mug is not well insulated and dissipates a lot of heat. I bought a better one at Bed, Bath and Beyond and now my coffee stays hot for hours. What is your specific concern?

I use it daily for work and coffee only. Hot for 2 hours, warm for about 3 more lukewarm the rest. It only holds two normal cups, and I sip from it all 9 hours at work.By the end-of-the-day I just drink it out which ever temperature it might be. I must stress that I sip from it and do not pour it out onto a cup. Not really hot. Hope this helped....

Debbie, Truthfully, I purchased this for a gift. The person I gave it to said it keeps her coffee very hot on the way to work, she lives 50 minutes from work. She also stated when she arrives the coffee/drink is still as hot as when she filled it. Hope this helps, Spencer

I have not used mine in a while, but as I recall it keeps my coffee hot about 4-6 hours depending on the temperature when poured. It makes a BIG difference if you preheat the tumbler first.

I just tested one in the microwave, having filled the mug near to the top. I used the "beverage" button and found the liquid hot and the handle cool. Previously, I'd just poured freshly brewed coffee into the mug with good result - handle stayed cool, no damage to the glass.

I don't know what the temperature of the coffee mug is. I do not try to get Cold coffee warm on my warmer. When I make my coffee in the morning I put it on the warmer and it stays perfect the entire time I am drinking it. I don't think it is meant to make a cold cup of coffee hot.
