Lochinvar takes care of heating and hot water at Lavender Fields

Heating, hot water and renewable specialist Lochinvar has provided a complete heating and hot water system powered by four air source heat pumps for a new luxury 72-bedroom care home set in rolling Yorkshire countryside.

The home which was delivered by main contractor Firecrest Construction is the latest addition to the retirement community at Lavender Fields Care Village, which also includes 24 privately-owned bungalows near the picturesque village of Barmby Moor. It is three miles from the famous market town of Pocklington in the spectacular East Riding, and the 72 luxury bedrooms enjoy views over the countryside and the community’s landscaped gardens.

Lochinvar was specified by Leeds based mechanical services contractor, Sayes & Co Ltd and fully supported for use by the main contractor, Firecrest to provide a fully integrated heating and hot water package including energy saving heat pumps, thermal store, two storage vessels and ancillaries.

The system, which was also fully designed and installed by Sayes & Co Ltd is managed by a priority control system that keeps energy use low while ensuring the right balance between hot water production and the home’s underfloor heating system.

The heat pumps were chosen from Lochinvar’s Amicus HT air to water heat pump range which can provide hot water at up to 63degC giving a highly efficient low carbon method of supplying domestic hot water in both existing and new build properties.

The system at Lavender Fields uses a three-port priority demand function which allows the system to prioritise hot water, in line with the specific demands of a care home, and then switch to heating mode when the hot water demand has been met.

This highly energy efficient approach is further boosted by using a thermal store that helps to smooth out the peak loads and reduces the number of times the compressor starts and stops – so helping to prolong operational life and improve reliability.

The Lochinvar system also includes cascade control which allows the system to closely manage the operating patterns of the four heat pumps to match demand. This is very energy efficient and is, therefore, in tune with the care village’s wider ambition of being a “fully sustainable community”.

The team at Sayes & Co Ltd selected Lochinvar because, to be successful, the project needed a fully integrated system with all the separate components working in close co-ordination. They praised the technical and after-sales support provided by the manufacturer, particularly mentioning the high levels of communication during the specification and installation processes.

Lochinvar’s Amicus HT range comprises 34 separate models with heating capacities up to 219kW.  They can operate in ambient temperatures as low as -20˚C in heating mode and can also achieve a coefficient of performance (COP) above four.
