Decarbonisation of the existing heating system to the residential blocks
Oxstalls Campus is a high-energy campus of forward-thinking and competitive students training for the frontline of healthcare, performing arts and making connections with global businesses through the Business School and Growth Hub while working alongside elite athletes at the international-standard Sports facilities.
Five of the onsite residential blocks were heated by local LPHW gas fired boilers, each distributing flow and return pipework to each floor with steel panel radiators located in each bedroom, the communal kitchens and corridors. Each boiler was replaced by a monobloc heat pump with LPHW flow and return pipework trenched to the existing boiler rooms.
A new distribution board was installed within the existing switch room to serve each monobloc and LV cable was trenched to each monobloc.
Key design issues resolved:
- Selection of naturally quiet air source heat pumps due to proximity of residences to Monobloc locations
- Shutdown of occupied residences for control valve installations
- Modification of of Radiator TRVs and lock shields
- Upgrade of existing BMS Controls to incorporate new equipment, control requirement and performance reporting for post installation analysis
Key Challenges:
- Working in an occupied residential environment. Tenants included healthcare students completing placements and working night shifts
- Managing noise pollution as student residences and domestic properties within close proximity
