Social housing: net zero progress report - quarter 2 2024

Project Title: Carron Estate ASHP Heat Network Project

Project Organisation: NG Homes

Technology Type(s): ASHP, Solar PV

Location(s): Springburn, Glasgow City Council

Grant Value: £3,695,187

Completion Date: July 2022

Project Headline: Installation of ASHP system to replace existing electric wet system in 314 homes in tower blocks.

Project Description:

This project saw NG Homes install ASHPs into seven tower blocks in the Springburn area of Glasgow, North of Glasgow City Centre. There are four 16-storey high-rise tower blocks and three 9-storey tower blocks situated on the Carron Estate. The 314 dwellings within the blocks previously had a mixture of ‘old’ inefficient electric storage and electric wet systems, which are expensive to run.

The project installed a Commercial-Grade Mitsubishi Ecodan CAHV Monobloc Air Source Heat Pump (ASHP) system which is connected to an underground district heat network that will serve all seven blocks. The heat network has pre-insulated pipework connected to insulated steel risers through each of the blocks. Insulated copper pipework forms the lateral pipework into each of the dwellings. The system also benefits from the installation of solar PV onto three of seven blocks.
