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.

Meet Our Team
Robert Brunson | Project Manager
Music has always played a major role in Robert’s life. His dad was in band and taught Robert how to sing and strum Beatles’ songs on his guitar. Thirty years later, Robert taught his own kids to play music using the Rock Band video game. But don’t challenge his family to a game; his daughter now plays seven instruments. Perhaps it was his appreciation for music that led Robert into a career of engineering and project management — in all of these situations, if one element changes, then there is an effect on other elements. Before joining Heatworks in 2019, he led the largest USAF Training System contract, valued at $179M, which included over 150 employees across 17 sites. Robert has two engineering degrees, his MBA, and PMP Certification. When not working, this “steak and potato” guy is an avid outdoorsman. He love hunting and fishing, restoring old cars (ask him about his ’67 Firebird), and spending time with his kids.
John Michael Burton | Senior Mechanical Engineer
John Michael is a Charleston local, born and bred. He grew up on Isle of Palms and Sullivan's Island before heading up north to Durham, NC, to get his engineering degree from Duke University. John Michael worked on heavy equipment and automated machinery before jumping into the startup world and falling in love with the fast-paced design. He put in a few years as a product-design consultant before joining Heatworks in 2019. John Michael and his wife live on the peninsula and spend their off-time traveling, being on the water, and reading good books.

In his current role, Jack is responsible for the strategy, roadmap, and feature definition for the MODEL 3. He also provides information to customers by way of technical sizing and support. Local to Charleston, Jack grew up on Sullivan’s Island, terrorizing local police with his dirt bike. He earned a bachelor's degree in economics, marketing and management at the University of South Carolina. 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.

In his free time, he loves to watch sports, soak up the sun, and enjoy the great food the area has to offer.
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

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.

Pete loves animals, is obsessed with British comedy, enjoys starting home improvement projects that he is unqualified for, and is still not quite sure why unicycling didn’t make him more popular in college. He and his wife, Tori, live in Charleston with Rusty, their pet squirrel. They can often be found watching B-grade horror movies while Rusty hides hazelnuts in their closet.

The rest is history!
