Nullpunkt: Building heating with ice

ZURICH - July 7, 2025 - PRLog -- What began as an ambitious idea in the summer of 2023 has become a reality: a fully functional prototype that successfully heated an entire house throughout the winter using nothing but water, ice, and clever thermal science. Now, Nullpunkt is taking the next big step with a Kickstarter campaign to bring their eco-friendly heating system to homes across Europe and beyond.

Over the past year, the Nullpunkt team has gone beyond the prototype. In 2024, they constructed a climate chamber, a high-tech environment where they can simulate real-world conditions and test performance under varying temperatures and humidity levels. This chamber has enabled the team to fine-tune the system for optimal reliability and efficiency.

Now, with rigorous testing nearly complete, Nullpunkt is poised for commercial launch in summer 2025. The Kickstarter campaign offers early supporters the opportunity to be part of the sustainable heating revolution and to help accelerate the shift away from fossil fuels and expensive electric systems.

"Our goal has always been to make home heating smarter, greener, and more affordable," adds Andreas. "Nullpunkt isn't just an invention—it's a solution for a future that demands cleaner energy and smarter design."

The system is compact, modular, and designed to integrate seamlessly into both new builds and retrofit projects. With zero combustion and minimal electricity use, Nullpunkt represents a bold step toward carbon-neutral living.

Why Ice?

The key lies in latent heat the energy released when water changes phase. One cubic meter of water releases about 93 kWh of thermal energy when it freezes. Nullpunkt captures this energy in a controlled cycle, providing clean, reliable heat.

As demand grows for alternative energy solutions, Nullpunkt is positioning itself as a frontrunner in the green tech market. The Kickstarter campaign will fund final development, production tooling, and the first wave of installations.
