Learn about the technology behind heatle,
the world's first smart liquid heater


very efficient, wireless heating technology




the energy goes directly into

the liquid and nowhere else


most quick & efficient

combo for liquid heating

"How do we heat our daily liquids?

With devices not well designed for that task.
As a result, we waste lots of money, resources and energy.

Fact is: for over 65 years, we didn't have a choice.

Now we do - with heatle®."

David, co-founder & CTO

Sketch from the first patent (1997)

The idea itself is not new.

The idea to combine the two most efficient ways for heating liquids: induction and immersion.

Since it was first patented in 1997,

many have tried to bring this idea to life.

From startups such as Miito to tech giants like Groupe SEB,

many brave souls have had their tough time.

Yet none of them could achieve satisfying results.

Now we have finally made it work.

And it's a global sensation.

Learn about the achievements that make it possible:


We had to overcome adamant technical challenges.




Squeezing power electronics with a massive 2.000W output into the smallest possible shape of only Ø18cm requires a fully custom design and circuit that the market has never seen yet.

Unlike cooktop pots, cups have varying thicknesses, widths and curvatures. Plus the disc moves around as bubbles form below. How do we keep it down, in the center and, of course, hot?

The heatle® disc's area is 92%
smaller than a standard pot and about the size of the "dead zone", an area not targeted by induction cooktops. How can we focus up to 2kW into such a tiny object?

All of this is now PCT patent-pending innovation.

Even the noblest of ideas is worth nothing when it's not being realized.

With heatle®, we are proud to be the first in the world to have overcome all enormous tech challenges - thanks to our patented solutions which enabled us to create the world's first working device of its kind.

Global innovation.

Made in Germany.


We did some comprehensive studies to let the numbers speak.

Each model was powered at 220VAC. 250ml of water (1 large cup) were boiled until turn-off. The tests were repeated 10 times and an average was taken. Further details in the video, including 500ml and 1000ml results.

Efficiency = how much energy wasn't wasted and actually went into heating your drink = kWh required*/ kWh used
*  = 
(4.184J/g°C * °C delta * 250g) / 3600000s
