Who We Are

We’re reinventing ways the world can heat and use water and other liquids. Through our patented, licensable technologies, like Ohmic Array Technology, water and other liquids are heated quickly, at higher volumes, and in the most efficient ways possible. Heated water tastes better. Temperature control is precise. Energy loss and equipment downtime is minimized. Our products improve the comfort of our homes, the quality of our lives and preserve our Earth’s precious resources: water and energy. 

Some companies are happy to stand still. To keep things the same, just because. They think, if it ain't broke, why fix it. We never settle. We don't believe in waiting or wasting.
