Thermos Work Series Flask – Exceeded My Expectations

Believe everything the reviews say. This is the best flask you’ll ever get. I’ve had several flasks over the years, but this one is by far the best. In comparison tests between this and two different supermarket flasks i’ve got, this out-performed them by miles, and this flask 36 hours after filling with boiling water, the water was only just cool enough to drink immediately from the flask without burning my lips, i measured 62 degress c after 36 hours, quite remarkable. (not that i’d drink hot water).

The original brand is still hot. My experience of this thermos 1. Liquid remains hot for around 5 hours and warm enough to drink for about 15 hours if unopened. The only heat escape is a small amount of conduction through the tough plastic screw-stopper2. If opened a couple of times and some of the liquid is displaced by cold air, the remaining drink remains warm for about 4 hours but no longer (depending on the amount poured out and for how long the stopper was unscrewed)3. It’s lightweight & portable, and at the same time tough & resilient4. On the minus side, it’s a bit priceya few reviewers claim their flasks don’t keep the liquid hot or that they work for a while and then stop working. The only reason for this can be that the vacuum-seal has gone, obviously a manufacturing fault or inconsistent manufacturing quality affecting a minority of the flasks, or else they may have been dropped/violently knocked at the premises of the retail seller prior to being shipped to these buyers. Current flasks like this thermos are a big improvement on the old fragile glass-lined flasks of the 1980s which would always shatter if dropped even once. Here are the specifications for the Thermos Work Series Flask:

  • Thermos vacuum insulation technology for maximum temperature retention; keeps hot for 24 hours and cold for 24 hours
  • Durable stainless steel interior and exterior with stainless steel cup
  • Cool to the touch with hot liquids, sweat-proof with cold
  • Twist and pour stopper allows you to pour without removing the stopper
  • 5 year guarantee

Absolutely brilliant flask – stays hot hot hot for days.

Thermos work series stainless steel flask. My husband bought this flask as he was fed up with his tea being cold half-way through the day. He thinks this flask is excellent. Tea stays hot all day long and the flask is very robust.

Reviews from purchasers :

  • Still Going Strong After 7 Years
  • Brilliant, you get what you pay for
  • Get what you pay for, fantastic item

I can’t really fault this flask. Filled with boiling water in the morning, the water is still warm 24 hours later. It stays very hot throughout the day so no complaints here. If i was going to nitpick, i’d prefer the cup to be a press-fit, rather than have a screw-thread, as my hot chocolate drinks can gum the thread up a little.

Brilliant, you get what you pay for. Brilliant, you get what you pay for, it might be slightly more expensive than others but its the first flask that has ever held my tea scalding hot all day. Others i have bought in the past have only kept my tea hot for an hour or so max, but this was still warm the next day, unbelievable, well worth the purchase.

Although a bit pricey, well worth it. I use mine for tea at work and it keeps it warm all day. Tough build too dropped it a couple of times and only minor dints.

Thermos work series stainless steel flask 1. 2l. I purchased this thermos work series stainless steel flask 1. 2l after trying a few other brands that i was not satisfied with. I reviewed a couple of other flasks and decided trying this one because the reviews were pretty good. With other flasks after pouring a cup then leaving for a few hours then pouring another one, the second cup is never that hot. Not with the thermos work series stainless steel flask. This flasks not exactly cheap but it is worth every penny. The packaging and quick delivery was spot on aswell.

Impressive stuff, to be honest. Impressive stuff, to be honest. Usually, flasks i owned before barely held temperature until the end of the day. And i didn’t expect, that when i open this one after 1,5 days, tea would be still warm. Needless to say that after 5, 10, 20 hours you still risk to burn your mouth with hot drink as it stays hot as if it was prepared 5-10 minutes ago. This thing is quite expensive for a flask, but worth its money for sure.

Hottest flask yet, well worth the money. . There were so many exultant reviews of this flask that i suspected the thermos marketing department had been slaving over a hot keyboard. Even so, i ordered the thermos thermax work series 1. 2 litre steel flask: it really does keep drinks hot for a long time, unlike the other two flasks i have had to chuck out. To test it, i made a flaskful of tea without milk (i added cold milk to the mug when i poured it out, if you are interested). After 3 hours, the tea was as if newly made. After 12 hours, it was as if new tea had just been left cooling in the mug for a couple of minutes i. Definitely perfectly drinkable and tasty. The difference was barely discernible from the 3-hour-old tea.

Good size sturdy thermos for my son who is an. Good size sturdy thermos for my son who is an electrician. It does what is says and keeps hot liquid hot for his long shifts.

Great flask, will buy another. . Have had this flask 2 years, simply amazing. I find filling it with boiling water for 10 mins then refilling it works best, the water will still be hot enough for tea about 16 hours later,coffee even longer. I only use white vinegar or bicarbonate soda to clean. I also have the thermos king food flask which is also excellent, you’ll save yourself a fortune with this combo.

I have used our flask on many occasions, it does exactly what it says. We have used water some 26hours after filling the flask and it still has enough heat to make a hot cuppa (i do recommend pre-heating the flask first). I wouldn’t buy any other flask.

Absolutely brilliant flask – stays hot hot hot for days.

Get what you pay for, fantastic item. Fantastic flask, keeps liquid hot for hours and even days. Forgot to empty flask for two days and the coffee was still like warm.

Best flask ever bought make it 6 am last cup 3 pm still hot.

I bought this flask because i was fed up of my flasks breaking, so far all is well. It keeps my coffee hot all day even when its only half full, the only reason i’ve given it 4 stars is because its only got one cup. If you use it every day it’ll pay for itself in a couple of months.

I can’t really fault this flask. Filled with boiling water in the morning, the water is still warm 24 hours later. It stays very hot throughout the day so no complaints here. If i was going to nitpick, i’d prefer the cup to be a press-fit, rather than have a screw-thread, as my hot chocolate drinks can gum the thread up a little.

Best thing i’ve done buying this. . Although this product is not cheap it definitely does the job. Well worth the money as it keeps the contents hot with the stainless steel lining.

    Still going strong after 7 years. I bought this in september 2010, and it is still going strong in august 2017as the descriptions says, it has a blue-grey enamelled/hammertone finish, and a polished stainless steel end/cup. Even after 7 years, apart from a few dents in the cup, the flask performs faultlessly. It is genuinely very tough indeed. It will keep tea very hot for at least 12 hours. The no-spill spout system is also very useful. A tip: since metal flasks tend to perform slightly worse than glass ones when it comes to keeping things hot, i make my tea by infusing the leaves separately – as you would making tea normally. Then, i rinse out the flask with boiling water to heat it up, bring some milk to just below the simmer point in a small pan and pour it into the flask, then top up with the infused tea. This makes sure the liquid inside is at its hottest when i seal it, rather than cooled by the addition of cold milk and a cold flask. Another tip: to avoid “rancid flask syndrome” – where the flask starts to smell bad – make sure you clean it and rinse it out when you’ve finished with, then leave it upside down until it is dry.

    Keeps liquids hot for more than a day. Keeps liquids hot for more than a day. We usually fill this up with tea for after our long hikes and if there is some tea left over, it’s piping hot even the next day.
