WaterFurnace Breaks Ground On Sizable Fort Wayne, IN Headquarters Expansion

WaterFurnace International, a leading innovator in geothermal and water source heating and cooling solutions, broke ground on a significant expansion of its Fort Wayne, Indiana headquarters on May 30th. The 173,000 square foot building expansion will more than double its current size, offering more flexibility to increase operating efficiencies and production capabilities to meet growing customer demand. It will also be equipped with multiple features that allow for future state-of-the-art enhancements as the company continues to grow.

Despite the considerable increase in space, the entire facility will continue to be 100% heated and cooled by WaterFurnace geothermal heat pumps that draw from the renewable energy of its existing pond. This commitment parallels the societal shift away from fossil fuels towards more sustainable energy solutions and underscores WaterFurnace’s dedication to environmentally friendly practices.

“This expansion reflects our commitment to innovation, sustainability, and the community. We’re investing in this 14-million-dollar project because we’re committed to growing as a renewable technology leader from right here in Fort Wayne,” said

CEO of WaterFurnace International, “With 320 dedicated employees, we are poised to lead the industry with our advanced products and exceptional service as the demand for sustainable energy solutions continues to rise.”

WaterFurnace’s expansion comes on the heels of two record-breaking years, driven by a growing demand for renewable energy technologies and the currently available 30% federal tax credit for geothermal systems. The company has built a reputation as an industry leader, known for its exceptional production efficiency, with unmatched lead times of just 3-5 days from order to shipment.
