Huge air source heat pumps lifted on to city roof

Timelapse footage has captured three large air source heat pumps being lifted on to the roof of a Cambridge art deco building overlooking the Market Square.

The units, weighing about 20 tonnes (20,000 kg), will replace gas-fired heating as part of Gonville & Caius College's £10m decarbonisation project.

On Sunday, they were placed on the Murray Easton Building, to serve the college's Grade I-listed Old Courts site on Trinity Street.

The college said it was a "key landmark" in the long-planned project, which was scheduled to be completed by the summer of 2026.
