We are changing the way the world heats water.

Rather than coils or traditional heating elements that scale and rust over time, our water heaters use our patented Ohmic Array Technology to heat water. Endlessly, on demand. And, since we use water as the heating element, you can rest assured that the hot water that comes from our units is purer and free from sediment.


Purer Hot Water

With no heating elements to rust or scale, the hot water that comes from Heatworks’ water heaters is purer than from any other heater in the world.
