A Mount Pleasant company that designs and makes tankless water heaters plans to hire 60 employees as it ramps up production.

Heatworks Technologies is in the process of releasing the third model of its Internet-connected device. The tankless units allow homeowners to set the water temperature down to the degree from their smartphones.

The company's hiring plans, announced Wednesday, will mark a significant ramp-up for the startup. But Heatworks, which currently has about a dozen employees, has been building momentum for much of the year.

The company has disclosed investments totaling at least $4.1 million this year, securities filings show, bringing its total haul to more than $10 million – a significant sum by the Lowcountry’s standards.

Heatworks also raised more than $160,000 on Kickstarter earlier this year.

And last week, it won an innovation award from the Consumer Electronics Show for its latest model.

The third iteration of the Heatworks water heater is something of a comeback effort for the company, which ran into issues with earlier versions that had computer glitches and damaging installation errors. The company has said the new unit is designed to prevent a repeat of those problems.

The company says it wants to do for water heaters what products like Nest did for thermostats - connecting them to the Internet and giving users granular control over a home energy hog. Heatworks says its app can set the length of a shower, for instance, or turn down the temperature.

As part of its expansion pan, the company is relocating its headquarters to a larger site to consolidate its offices and laboratory at 2353 Highway 17 in Mount Pleasant. Heatworks said it is expects to to complete the move by the end of year and begin hiring more employees in early 2018.

“What brought us together initially was the frustration with getting hot water delivered to an outdoor shower," CEO and founder Jerry Callahan said in a written statement. "We were sure if it was happening to us, then other people were probably having the same dilemma. Not only did we seek to solve our initial problem, but we’re changing the way the world heats water.”
