Our Mission

To become the standard way
of heating liquids, worldwide.

With the ongoing energy crisis, the world needs actionable & effective change. InstaHeat AG is a Zurich-based cleantech company transforming liquid heating solutions since 2019.

The Problem

Traditional heating is broken.

Calcified Pipes
01

Mineral Deposits

Heating elements within boilers reach 300°C. Excessive heat causes limescale buildup, requiring constant descaling and maintenance.

300°C surface temperature
Overheating
02

Overheating

Lack of heat control means liquids don't heat evenly. No homogeneous flow causes burning and product waste.

Uneven heat distribution
Energy Waste
03

Energy Waste

Up to 50% energy loss due to inefficient heat transfer. Low heating efficiency impacts both costs and the environment.

50% energy loss
The Technology

Direct Ohmic
Heating.

The ohmic heating principle generates heat by guiding electrical current directly through the liquid that flows between two electrodes placed along a pipe.

The liquid itself heats up instantly due to its electrical resistance. This eliminates heating elements and their associated problems entirely.

Our Story

A story of determination.

2016

Two 16-year-olds, Alexey Gromov and Fabian Dietschi, met at an apprenticeship for electronics-technicians at the ETH. Overnight, they developed the entire business case for a revolutionary heating technology.

2018-2021

The Big Hiatus: Focused entirely on regulatory issues of ohmic heating for liquids. Got directly involved with global authorities and set up new standards worldwide, based on their patent.

2019

InstaHeat AG was incorporated in Zurich, Switzerland. The determined decision of two young engineers became a reality.

2025

The HeatFlow Series debuts as an integrated device within a fully automatic commercial coffee machine, ready for production rollout.

The Team

The minds behind.

United by a vision to revolutionize liquid heating technology.
