Never boil water again: the hot water bottle without a kettle
For 82% of our customers, this is the main reason. How a hot water bottle works without hot water and what it changes in everyday life.
Into bed in the evening, cold feet, and then back out again: kettle on, wait, pour carefully, screw the stopper on, back to bed. That exact routine is why we built the Vaermflasche.
How it works
- Plug in: Connect the cable to the bottle, choose a level with plus, tap start.
- Wait a moment: After around three minutes it's noticeably warm. The bars show you how far along it is.
- Unplug: Only the bottle comes to bed. No battery, no cable under the covers.
What changes in everyday life
- No hot water in your hands, no scalding while filling.
- Heat it up right by the bed if there's a socket there.
- Warm it up again without getting up: just plug it back in for a bit.
- No water to pour away.
82% of our customers say the best thing is not having to boil water anymore. For 53%, what counts is being able to switch it on right in bed.
Does it feel like a real hot water bottle?
Yes, that mattered most to us. The sealed filling makes it weigh around 1.6 kg, it's soft, and it sloshes when you move it. It snuggles up to you like a classic hot water bottle, just without the kettle.
Never boil water again. Plug in, 3–6 minutes, warm. Up to 70 °C, no battery, 30 nights to try.
