WATTER is pioneering a new era in household utilities by transforming water heating into a smart, self-sustaining investment. Their innovative solution utilizes waste heat from powerful compute devices (GPU to BTU) to heat water and simultaneously generates revenue through compute power. WATTER aims for a sustainable future, being the first Net Zero compute solution. The product is designed as a drop-in replacement for existing water heaters, installing in a few hours. It features AI for smart heating, optimizing the hot water experience and tailoring it to user needs. The all-electric design facilitates easier installation and app-based control, contributing to a greener planet.
