When Enertech first began in 1996, it was with one simple philosophy: People come first. Since that day, that’s exactly what we’ve been doing, and we now manufacture great brands including TETCO. As a people-centric company, we believe in family values, loyalty beyond reason, assurance in quality craftsmanship, and making the world a better place. That’s our roadmap, carefully guiding every decision we make. In fact, it’s more than just what we believe; It’s simply who we are.

Thinking Differently…

At Enertech, we think a little differently about geothermal technology. Because of our unique approach, we continue to find ways to make it even better for contractors to install, and business and homeowners to enjoy. We do all of this while maintaining our commitment to product excellence and extraordinary quality.

When it comes to TETCO geothermal systems, there’s nothing more important than quality. In fact, we believe that quality is everyone’s job, and it’s taken seriously from start to finish. And it’s not just because we want to make good products, it’s because we are proud to make the best products.

Welcome to Enertech Global, the company that’s making geothermal better!
