"Revolutionizing Urban Heating: NYC Apartment Windows as the Next Heat Pump Frontier"

New York City is investing in the development and production of 30,000 heat pumps for its public housing, with one company, Gradient, already rolling out 36 window units and reporting promising results. These window heat pumps are designed to be more efficient than traditional heating systems, potentially reducing heating costs by significant percentages. The hope is that heat pumps can help transition away from fossil fuels, with the goal of having heat pumps account for 65 percent of residential heating, AC, and water-heating shipments by 2030. The technology is seen as a relatively affordable and simple solution that could benefit both residents and the environment, with the potential to significantly reduce energy consumption and emissions in the residential sector.
