Nullpunkt AG is a Swiss cleantech startup based in Oberengstringen near Zurich that develops ice-storage heat pump systems for single-family homes. Its patented Triton system combines an outdoor heat exchanger, an ice storage unit and a heat pump to deliver efficient, near-silent heating without the borehole drilling or bulky outdoor units required by conventional geothermal or air-to-water heat pumps. Founded by three experienced engineers, the company entered the market in October 2025, has since installed multiple systems across Switzerland and sells through a growing network of installation partners.
