ISI Technology and CEO Jerry Callahan have created the Heatworks MODEL 1. The Heatworks MODEL 1 is the world’s first 100% digital water heater. Replace or improve any existing water heating system while enjoying instant and infinite hot water, a significantly longer lifespan with zero required maintenance, and ultimate control.

Using electrical current to silently heat water while monitoring power 60 times per second, the MODEL 1 is capable of maintaining temperature within 1 degree Fahrenheit. As a result, the Heatworks MODEL 1 reduces up to 40% of energy usage and 10% of water usage.
