Discover our innovation from Germany which lets you heat liquids to the right temperature quickly, conveniently and sustainably.

Your new kettle
is not a kettle
The Heatle is the world's first induction-based immersion heater - a premium device developed and produced in Berlin, which combines authentic Japanese design with revolutionary German technology united.
With the elegant eye-catcher you can easily heat, warm up or cook anything - whether hot Tea at perfect temperature or lukewarm baby milk in seconds, as well as cocoa, coffee, mulled wine, noodle soup and much more.
Not only can you save a lot of energy, but also space in the kitchen, time and nerves when preparing and cleaning. Let yourself be enchanted! You deserve it.
A dynamic ecosystem
as demanding as you

30-100°C
What's the point of having an "accurate temperature" in the kettle if you're going to pour the water anyway?
Save that 10-15% of energy on the spot. Your Heatle measures the temperature directly in the vessel and stops automatically when it is reached. So you always know what you're drinking - or your baby.
Already available

50-1500ml
Forget about the minimum filling quantities of kettles. Or that you heat significantly more water so that the limescale doesn't slosh into your cup.
With the Heatle, you finally heat only the amount you need - from babies to the whole family. For larger quantities and vessels, we recommend our extra-large heating disc.
Already available

Not just water
The Heatle is not a kettle. It is a true all-rounder.
With the Heatle you can heat baby milk, mulled wine, broth, porridge, cocoa and much more - or reheat cold tea/coffee. Simply stir fatty liquids with the heating rod.
Already available

Duo Mode
Only 1 person lives in 41% of German households. In 34% there are two. A kettle with 1.7 litres has not corresponded to the real demographics for decades.
With the Duo Mode and two rods, you simply heat two cups (same liquid and quantity) at the same time - without the need for a teapot.
Already available

Moka, Mate & Co
Perfect coffee or mate in just a few moments? Thanks to our unique induction technology, it will soon be no problem!
Your Heatle will soon be able to heat approved metal vessels quickly and safely. The current version already supports this future accessory.
Already in development

Egg Cooker & more
The Heatle makes liquids hot. But hot liquids are not only needed for drinks.
How about eggs, sous vide, pasta or steamed broccoli without extra electroniccal devices? Perfect results thanks to app control. The current version already supports this future accessory.
Already in development

Water Bath accessories
Some liquids or foods should not be heated directly with a heating element.
With the Heatle, the heating element (disc) is detachable from the thermometer element (rod). Use it to heat baby food, chocolate coating and anything else that needs to be heated indirectly and at the right temperature.
Already in development

Hot Water Bottle
It doesn't always have to be pills - sometimes a little warmth is just the right thing.
With the cosy Heatle hot water bottle, you or your child can quickly get the warmth you need without scalded fingers.

Pure Taste with a Clean Conscience
Your Heatle is clean and sustainable in several ways, because it can replace several electrical devices in the long term, only heats the required amount to the right temperature and your liquid only has contact with stainless steel without BPA and microplastics.
With the Heatle, we fight the enormous waste of energy, as we all always heat too much water to a too high temperature - and with old-fashioned devices that not only constantly calcify, but are also far from efficient.
In addition, each Heatle also reduces e-waste, since electrical appliances such as water and egg cookers, baby food warmers, sous vide sticks and much more are almost never recycled. Heatles can also be disassembled and repaired.
Truly a World's First
The Heatle is no ordinary induction cooker. Actually, no other device in the world can heat a small piece of metal in your cup using induction - and certainly not with an enormous power of up to 2.000 Watt.
Many other companies tried and gave up - after 5 years of research, we are the first to succeed. Heatle is ready for the market, CE-approved and in series production in the heart of Berlin.


Real oak wood
The high-quality control knob of the Heatle is made of sustainable, European oak wood (solid, multi-oiled), is an absolute eye-catcher and radiates warmth and serenity. Each Heatle is thus as unique as its owner.
Smart Rod
Heat-resistant handle with integrated LED (operating light) and built-in BLE antenna for wireless transmission of temperature.
Powerful and compact
The world's smallest induction hob with up to 2,000 watts of power. High-quality, matt surface without cast seams (dividing lines) in black and white.
Temperature sensor
In the wand are patented electronics that work completely battery-free. The sensor measures the temperature inside the vessel and transmits it wirelessly to the base. There is only stainless steel in the drink.
Pure white LED matrix
Easy, intuitive menu navigation thanks to high-quality LED dot matrix (display) in a modern, unobtrusive style.
We love our Heatle. It hardly takes up any space in our small kitchen and looks fantastic.

Frequently Asked Questions
Delivery times and regions
If you take part in the upcoming pre-sale, you will receive your Heatle before or in June 2023. The earlier you order in the pre-sale, the earlier you will receive your delivery. We deliver chronologically. We order the raw materials and prepare the production after this pre-sale (we need the money for this). The production of the units from batch 3 starts as soon as we receive the raw material. We already have the critical components and chips in stock.
We only ship within Germany, Austria and Switzerland for this sale. So only devices with the appropriate plug. Other countries and plugs (e.g. England) will be available again later.
What if I miss the presale?
Pre-sale is only available while stocks last. Due to the chip shortage, we can only produce a limited, small quantity. The discount only applies to pre-orderers, as they pay several months in advance and are willing to wait a long time.
If you miss the pre-sale for any reason or are not quick enough with your purchase, you will be able to order again later (at a different price if necessary), but the subsequent batch will not be produced until the end of 2023.
Payment and Money Back Guarantee
You must pay for the unit in full at the preferential price to order a Heatle during this pre-sale. This is the only way we can order the raw materials and finance the production. Until the production of your Heatle has started, we will refund you the amount at any time and at short notice - so you can easily and informally cancel. By doing so, you free up your place in the batch and someone else will be happy to get the Heatle several months earlier (and cheaper). Of course, you can return the device within 14 days of receipt in accordance with legal guidelines and get a full refund.
Why are you doing a presale? Use of funds?
As a hardware start-up, we have to make advance payments, order components, commission suppliers, set up logistics, etc. a long time before you get your Heatle. With the money from the pre-sales we finance this production. Salaries, rent and other operating costs that are not directly related to the production of your Heatle are financed exclusively with venture capital from our investors. As soon as we have many more Heatles in circulation, i.e. from the middle of 2023, we will also get loans from banks and will pre-finance stock that we can then sell without waiting.
Since a Heatle takes some time to be produced at our premises in Berlin, we have to start planning production and ordering material early so that we don't get any idle time, which would be financially unsustainable for our production premises in the expensive capital.
.Questions about the product and service
Properties, dimensions, material, weight...
Why is Heatle efficient and sustainable?
There are many reasons, but here are the main ones:
1. You only heat the amount you need, instead of 2-3x as much as in the kettle, where you choose the cup later. Many also do it so that the nasty limescale deposits don't flow into the cup. Either way, the classic kettle isn't designed for the modern demographic.
2. Especially with small amounts, Heatle is super efficient, while kettles waste 40-60% of the energy.
3. You get the temperature you need - in the vessel and not in the pot or kettle. If you have 100°C in the kettle, only about 80°C will arrive in the cup.
4. You have one multi-liquid maker, baby milk and soon eggs, sous vide and more. This saves us tons of e-waste and, of course, space in the kitchen.
5. Heatle is repairable and recyclable. And of such high quality that it is also worth fixing it instead of throwing it away.
6. Heatle is packaged plastic-free and recyclable and will be shipped without an extra outer box.
Which liquids and vessels work?
Use cases we tested: water (tea, baby food), milk (including vegan milk), infant and breast milk, cocoa, mulled wine, light soup (like bouillon, or a noodle soup out of the box / ramen).< /p>
All non-ferrous (non-metal) vessels can be used, e.g. your mug/bowl/pot can consist of:
- glass
- plastic
- ceramic
- porcelain
- Paper
- Wood
Make sure that the vessel is able to maintain the temperature or use the soft mode because the pane sometimes gets hotter than 100°C. Some cups are e.g. B. not intended for boiling (100°C) water. If you have a metal cup or container with metal parts, do not use it on the Heatle unless it is officially Heatle Certified. It can be dangerous because it heats even the handle and doesn't regulate the temperature.
How long does it take for a cup/litre? maximum amount?
The time it takes the Heatle to heat the liquid mainly depends on the vessel (bottom thickness) and the amount of liquid. For example, Heatle can boil 250ml of water in a thin-bottomed cup in just under a minute, a liter in 3-5 minutes depending on the vessel and the size of the heating disc.
1.5 liters is the maximum capacity we recommend, as long as your vessel supports that volume. Please note that Heatle is designed for quick heating of single servings, which is the main need for most of us. Heatle needs a breather when you heat too much too many times in a row.
Will the rod work on my induction cooker?
There is no existing induction hob that can heat such small heating discs. That's why we developed our own technology and applied for a patent. So you need our base to heat small metal bodies.
Does Heatle work automatically or do I have to be there?
You don't have to hold the rod, just set your desired result and move on to more important things. The Heatle stops heating when it reaches the set temperature. There is an audible feedback/signal in the unit as well as push notifications in the future. However, with thicker/greasy liquids, stirring is recommended to avoid burning.
Can I keep warm or heat two cups at the same time?
Two cups at the same time is possible in the new Duo mode, which is also available in your Heatle. For this, please order a second rod including heating disc as an accessory. Heatle Duo works best with identical vessels and quantities.
Keep warm is currently under development and will be available soon, so also in your Heatle from this batch.
.After use: filing and cleaning
The rod is not actively heated, it is heated by the liquid (just as the cup itself is heated by the water). The interchangeable pane is actively heated at the bottom. It is as hot as the liquid itself, i.e. up to 100°C. You can place it on any suitable surface, such as a plate, to cool it down. After 3-5 seconds under tap water, the pane is cool again. You can also attach the magnetic rod and disk to a metal surface to keep it away from children or the elderly if necessary. We recommend using the trays provided.
The heating discs are available in different sizes, they are magnetically removable and can be put in the dishwasher or cleaned by hand, depending on how dirty they are . The stick itself should not be put in the dishwasher, but can easily be cleaned by hand. In the future we will provide an individual cleaning solution to remove limescale and other stains (e.g. milk, tea).
App, Smart Home and integrated version (Heatle Inside)
You don't need a smartphone or an internet connection to use your Heatle. You can simply use the rotary knob and the integrated display to access all standard functions. Heatle does not have its own internet connection, but uses your smartphone as a gateway to get updates, maintenance or access to new features.
In the future we will offer ways to connect your Heatle to connect to existing smart home systems as well as voice assistants such as Google Home, Alexa/Echo, Siri, etc. Stay tuned for our upcoming IoT and API updates. In the beginning, the Heatle is an independent device.
The integrated version, which is installed directly in worktops or tables, will also be available soon, but only for specialist companies that also use it can install. As a consumer, you cannot obtain this solution directly from us.
About induction and electromagnetic radiation
Heatle is a miniature induction hob and has been tested and CE certified as such. If you are not allowed to be near electromagnetic fields or induction devices for medical reasons (e.g. pacemakers, pregnancy, etc.), treat the Heatle like other induction devices.
In contrast to microwaves, we work with induction, which in our case works with relatively small magnetic fields with a very limited range, which become exponentially weaker the further away they are from you. That's why your Heatle heats with less power when the bottom of the cup is thicker.
