Carrier has signed an agreement with Robert Bosch North America Corp. to make residential and commercial geothermal and water-source heat pumps.

Terms were not disclosed. The transaction is subject to regulatory approval.

Geothermal HVAC systems use up to 50 percent less energy than conventional systems, according the U.S. Energy Department. And with sales of geothermal heat pumps expected to triple within the next 6 years, Carrier said the agreement with Robert Bosch will allow it to tap this growing market.

The equipment will be made at a facility in Fort Lauderdale, Fla. Both company’s sales and brands will remain separate.

“The Carrier team is excited by the opportunities this agreement will provide,” said Chris Nelson, president of residential and commercial systems at Carrier. “By bringing together the strengths of both companies, from Carrier’s rich legacy of innovation to Bosch’s well-equipped manufacturing plant in Fort Lauderdale, we will deliver a high level of value to our customers.”

Richard Soper, president of Bosch Thermotechnology Corp., said it was an exciting opportunity.

“Geothermal heating is one of the most cost-effective and environmentally responsible heating and cooling options available to consumers,” Soper said. “Establishing a relationship between Carrier and Bosch will allow us to leverage our research and development resources and continue to deliver high quality manufactured products to our customers.”
