Johnson Controls highlights cost and emissions savings from heat pump applications
MILWAUKEE, Wisconsin, USA, 10 June 2025: Johnson Controls announced through a Press Release that its commercial heat pumps helped customers achieve an average 53% reduction in annual heating costs and a 60% drop in emissions during 2024. The company said these outcomes were achieved through installations across industrial, healthcare, municipal and utility sectors.
According to Johnson Controls, the results reflect a growing adoption of heat pump technology as customers prioritise operational efficiency, cost reduction and climate action. Katie McGinty, Vice President and Chief Sustainability and External Relations Officer, Johnson Controls, said: “In this dynamic world, we are working in true partnership with our customers to deliver on multiple key priorities. Our state-of-the-art heat pumps ensure uptime, runtime and reliability. At the same time, cash is being conserved for growth as heating costs are cut by more than half, providing a significant competitive advantage.” McGinty added: “Achieving these outcomes while also accelerating climate action is just the kind of all-in partnership that our customers are calling for. We are honoured to join with them in making the vision a reality today.”
Johnson Controls cited several international installations to demonstrate the impact of its heat pump systems. In Spain, the company reported a leading food manufacturer saved €1.5 million annually and reduced CO2 emissions by nearly 2,000 tonnes. In Germany, a hospital reduced energy costs by 30% using geothermal heat sources and met 80% of its heating demand, Johnson Controls said. The company added that in the United States, Children’s Hospital of Alabama deployed heat pumps and digital solutions to reduce natural gas use by 69% and cut annual energy costs by $680,000.
The company said that beginning in 2026, four large-scale heat pumps in Hamburg, Germany, will use treated wastewater to supply heat for approximately 39,000 homes through the district heating network. Johnson Controls said in the United Kingdom, Hounslow Council reportedly replaced gas boilers with air source heat pumps, reducing energy costs and CO2 emissions by 50% across over 60 schools and public buildings.
Johnson Controls stated it has one of the most comprehensive global heat pump portfolios for commercial, institutional and industrial applications. The company said it also offers heat pumps using low and ultra-low global warming potential refrigerants.
Johnson Controls said recent additions to the company’s portfolio include the YORK® CYK Water-to-Water Compound Centrifugal Heat Pump, which delivers hot water up to 180°F and is up to four times more efficient than traditional boiler and chiller combinations. The YORK® YMAE modular air-to-water heat pump, also highlighted by the company, produces hot water up to 140°F and operates in cold climates. In Asia, Johnson Controls said it has introduced the YORK® HPS-H 200 and the YSPA-V screw heat pumps to support energy-saving and low-carbon goals across multiple industries.
