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

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.

Mike Wieckowski | Chief Technology Officer

Mike was born in Buffalo, NY, and tinkered with electronics and computers since he was a little kid. He received his doctorate from The University of Rochester in 2007 and then spent three years as a post-doc at the University of Michigan in Ann Arbor. Mike came to Charleston to run a research lab developing underground radar systems and work on a few startups. That all changed when Mike bumped into Heatworks' CEO Jerry at a TechCrunch event. The rest is history!
