New hybrid heating system installed at Grantham Health Centre G
rantham Health Centre in Lincolnshire has upgraded its heating system with a high-performance hybrid solution from
Hamworthy Heating. The system combines Stratton mk3 wall-hung condensing gas boilers with a Tyneham 290HT natural refrigerant ASHP and a 500-litre buffer vessel, delivering reliable, year-round heating, enhanced control, and long-term sustainability. The previous system relied on three ageing
floor-standing gas boilers that had reached the end of their service life. The decision to install a hybrid system was
driven by the need to meet decarbonisation targets while keeping capital expenditure manageable. Detailed surveys of the existing single-pipe heating layout and legacy emitters established the requirement for consistent high flow temperatures of at least 65°C, ensuring compatibility with the retained radiators and pipework. The hybrid system uses the ASHP during milder weather and switches to the Stratton mk3 boilers as conditions get colder. A BMS automatically selects the appropriate heat source based on outdoor temperature and flow requirements, maximising seasonal efficiency, reducing running costs, and maintaining comfort. Installation was completed over seven weeks while the health centre remained fully operational. A temporary hire boiler ensured uninterrupted heating. Greenway Building Services provided
consultancy, overseeing surveys, system specification, and operational planning, while Arthur Pollard Ltd carried out the installation. Their collaboration with Hamworthy Heating ensured a reliable, energy-efficient, and adaptable solution. Paul Jones, Regional Capital Project Lead – Midlands at NHSPS, said: “The recent
heating upgrade at Grantham Health Centre exemplifies our commitment to sustainability and futureproofing our facilities. This project is a testament to our dedication to creating sustainable healthcare environments that are equipped to meet the evolving needs of our communities.”
