Networked Ground Source Heat Pumps (GSHP) on a new-build and retrofit housing project

Ice Works Apartments, Worcester

Kensa Contracting has installed Networked Ground Source Heat Pumps on a new-build and retrofit housing project in Worcester, The Ice Works.

JJS Developments Ltd created 54 modern apartments on-site, building several detached apartment blocks from the ground up and converting a derelict Victorian mill-turned-factory that once commercially manufactured ice using an ammonia-based refrigeration process.

Project overview

Each newly built dwelling and flat in the converted Ice Works factory features Kensa’s ground source heat pumps, which use sustainably sourced heat from the ground to keep the homes comfortable all year round.

Using ground source heat pumps to provide sustainable heating for the apartments feels complementary to the building’s history, as the technology mirrors the refrigeration process used in the Victorian era to produce ice.
