Who We Are

At Heatworks, we’re meticulous about making things better. Products that improve the comfort of our homes, the quality of our lives and preserve our Earth’s precious resources: water and energy. That’s why we reinvented the way the world heats water.

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, especially when it comes to water. That's why we developed Ohmic Array Technology. And that's why we will continue to heat water in the simplest, purest and most efficient way.

Jack lives on the peninsula of downtown Charleston and spends his free time playing golf, guitar, cooking, and enjoying his time on the water.

Jerry Callahan | Founder and CEO

An inventor at heart, Jerry founded Heatworks the day he realized the water heater he needed didn’t exist. Rather than buy an inferior product, he decided to find a better way to heat water. That has been his focus for the last 12 years. Now with over 50 combined patents, Jerry leads a team of heating, technology and plumbing veterans to continue to build Heatworks' family of products. 

Jerry grew up on Cape Cod, MA, and studied naval architecture at MIT and the Stevens Institute of Technology. After attaining his MBA from University of Chicago, Jerry co-founded Blue Rhino, the world’s leading propane cylinder exchange company.

JP Carroll | Director of Business Development

JP started with Heatworks in December of 2016 and is focused on building and leading B2B and e-commerce sales. He has over 20 years of sales and sales management experience in the high tech industry, most recently from home automation leader, Savant. JP lives in the Charleston area with his wife and black lab, Bella. In his spare time JP likes to golf, build things out of wood, ski and cook. His two children are grown up and are almost off his payroll.

In his free time, he enjoys playing golf and spending time in the outdoors.

Russ Deuell | Program Manager

With a degree in mechanical engineering and a zest for making things work better, there is no wonder why Russ met his wife in the parking lot of a Home Depot. (Ask him to tell you the story!) He has an extensive background in program management, working in both the technical and integration sides of new and existing products. He spent 13+ years with Intel, overseeing a team of 20 engineers in a Center of Excellence, where he flourished working alongside senior management as well as engineering teams. Russ’s love of start-ups began after receiving his MBA from Babson College in Entrepreneurship. Fast forward to now, his main focus at Heatworks will be to ensure that the right product is developed to meet or exceed quality standards and is delivered on time. In his free time, he enjoys golfing, hiking, fat tire biking, and kayaking, as well as spending time with his wife, five grandsons, and one granddaughter in Summerville, SC.

Lindsey Khuong | Customer Support Associate

Having called over 12 states home, it’s no wonder Lindsey wants to one day live in an RV and choose her destinations by closing her eyes and dropping a pin on the map. At Heatworks, she is one of the friendly folks you may speak with if you call our Customer Support Team and need help. Outside of work though, you better not mess with her — she is a doomsday prepper, enjoys archery, and honing her shooting skills at the gun range. Prior to joining our team, Lindsey provided technical support for several companies, and even managed an entire health system’s medical database. When not on the clock, you will find her cooking gourmet meals or baking for her family of four, redoing furniture (her last project was her son’s computer table), or caring for her two dogs and tortoise.

Julie Klions | Firmware Engineer

Julie is responsible for developing, maintaining, and testing firmware for a variety of Heatworks products. She graduated with a bachelor's degree in engineering from The Ohio State University and has a strong background in machine control software. When not working, you can find Julie either running or cooking.

Robbie attended Trident Technical College, where he received an associate's degree in industrial maintenance. He enjoys spending time with his teenage daughter, fishing, grilling, and watching golf and football. But be warned -- If Tiger Woods or the Gamecocks are playing, do not call him. 

Greg Lyon | Director of Engineering

Born with a keen interest in figuring out how things work, Greg grew up in New York tinkering with go karts, explosives, trumpets and sailboats. It's no wonder he holds a Bachelor of Science in Mechanical Engineering from Northeastern University. 40 years later, his name is on 29 patents, having spent most of his career involved in research and development for companies like GE, Leviton, Thomson Industries and American Standards Testing Bureau. In 2000, he founded a consulting firm dedicated to the development and deployment of disruptive technologies. He met Jerry in 2006 through a mutual friend and has been involved in the Heatworks technology and products since. Greg’s pastimes include music and water sports.

The rest is history!
