Prospect House shows what commercial heat pump retrofit can look like in practice. Working with Together Housing, Panasonic Heating & Cooling Solutions has helped replace ageing gas boilers with R290 air-to-water heat pumps, building on a partnership that has already delivered thousands of domestic installs.

Panasonic Heating & Cooling Solutions has successfully supported Together Housing in the decarbonisation of Prospect House, demonstrating how commercial buildings can transition away from fossil fuel heating while improving comfort, efficiency and sustainability.

The project marks another milestone in the long-standing partnership between Panasonic and Together Housing, which has already delivered more than 2,000 domestic heat pump retrofits across the housing association’s residential portfolio. Building on this success, Together Housing has now expanded its decarbonisation programme into commercial properties as part of its ambitious commitment to achieve net zero and remove fossil fuels from its buildings by 2038.

To support the project, Panasonic’s M Series R290 air-to-water heat pumps were installed at Prospect House, replacing three gas boilers with four 30kW units. Designed specifically for larger commercial applications, the M Series provides a flexible, low-carbon solution capable of delivering high-performance heating while reducing carbon emissions and running costs.
