Charleston-based ISI Technology recently secured $2 million in seed funding to commercialize its digital water heater.

Additionally, more than 1,400 backers also gave $436,000 to ISI Technology as part of a Kickstarter campaign. ISI Technology plans to use the funds to commercialize and produce its Heatworks Model 1. The heater connects to a home through Wi-Fi, and the homeowner can control the water temperatures digitally.

“People have become resigned to a mediocre hot-water experience, where water takes minutes to heat and changes temperatures without warning,” ISI Technology CEO Jerry Callahan said in a statement. “The Heatworks Model 1 is the world’s first digital water heater, with a pioneering architecture that reliably provides hot water when you need it, at the exact temperature you like.”

Removing the need to wait for water to heat up, the company estimates that the water heater saves up to 40% of energy and 10% of water.

The digital water is roughly the size of a shoebox. It uses a patented direct electrical resistance heating process that heats water molecules with electricity. A digital temperature control uses a microprocessor and sensors to measure and adjust the water temperature.

“Water heaters, as most of us know them, have been around for more than 100 years and rely on antiquated technology to deliver one of the most important amenities in the home,” said Greg Tew, associate professor of the School of Architecture and Design at Virginia Tech, in a statement. “ISI has developed a much needed technological overhaul to the water heater that delivers the benefits homeowners demand.”

ISI plans to sell its water heater nationally sometime this year. More than 1,500 water heaters are on order.
