Revolutionizing instant heating of liquids 

With InstaHeat's Ohmic heating-based industrial flow heater, liquids can be heated directly, instantly, and precisely to the desired temperature.

No metallic heating element. No burning!


Headquartered in Zurich, InstaHeat is a technology-based start-up founded in 2019 that is revolutionizing liquid heating systems.

Our Solution


Heating systems for over 1000 years have involved heating metal and bringing it in contact with the mass that needs to be heated, be it a kettle, a boiler, or a cooker... With our InstaHeat flow heater, we can revolutionize the heating of liquids with complete energy efficiency and minimal resource wastage.

Using our Ohmic heating technology-based Flow Heater...

  • Heat only when needed; eliminate energy losses
  • Install at the point of usage, keeping the appliance compact
  • Heat any  liquid precisely with increased time and energy efficiency
  • No corrosion; low maintenance

The problem we solve

Significant drawbacks of the conventional heating techniques used worldwide include:

  • Lack of heat control and excessive heat generation
  • Depending on the structure of the house, a 20 - 40% loss of energy consumption
  • Calcification of the heating element, reduces heating efficiency and results in colossal maintenance costs.
Tech Ancor


The InstaHeat technology works using an electronic device, i.e., our industrial flow heater, which applies an electrical current directly to any liquid that flows through a tube and into the flow heater. The electrical power homogenously and instantaneously converts into heat within the liquid. And, as long as the liquid conducts electricity - be it water or milk - it will get hot to precisely any required temperature. This technique ensures that the heated liquid does not undergo molecular changes, or split into its atomic elements.
The InstaHeat flow heater replaces the traditional metal heating equipment within the appliance, such as a kettle, coffee machine, etc. Hence, instead of bringing a hot metal part (susceptible to corrosion, damage, uncontrolled temperatures, and energy loss) in contact with the liquid, the process turns the liquid itself into the heating element itself. The result:  efficient and effective heating with zero energy and resource waste.
