Heat Pumps Today

12 A 1.9MW heating system powered by highly efficient CIAT ground-source heat pumps is providing low-cost, low-carbon renewable heating for Coletta & Tyson, one of Europe’s largest independent nurseries. Leading UK Nursery Invests in High-Efficiency Ground Source Heat Pump Info www.ciat.uk.com/news/ciat-launches-dynaciat CIAT is part of Carrier Global Corporation (NYSE: CARR), the leading global provider of healthy, safe, sustainable and intelligent building and cold chain solutions. Coletta & Tyson are a major grower of garden bedding plants with nurseries covering 400 acres in East Yorkshire. The company commissioned Ebtech Energy Systems, a leading specialist in large water-source heat pump projects, to investigate options to replace an existing oil-fired boiler used for heating its main growing site near Beverley, Hull. Options considered included biomass boilers, biomass-fuelled combined heat and power (CHP) and ground-source and air-source heat pumps. Reflecting the space available on site, and the favourable underlying geology, a ground-source heat pump system based on CIAT units was chosen as the most ecient and cost- eective option to provide for the year- round heating requirements of the centre’s growing areas. Ebtech’s design is based on three DYNACIAT water-to-water units, supplied by Cool Systems Distribution Ltd, linked October | November 2021 I N S T A L L A T I O N to open-loop boreholes drilled into the underlying chalk aquifer. The system pumps ground-water from four abstraction boreholes up to 30 metres deep, passes it through the heat pumps to capture and upgrade its thermal energy, and then returns it to the ground via four re-injection boreholes. With a diameter of 450 millimetres, the boreholes can supply up to 45 litres per second of water to the heat pumps. The installation supplements an existing 2MW ground source heat pump installation completed two years ago, also based on CIAT units, to provide the majority of heat across the site with the existing oil boiler retained for back-up and extreme peak-load requirements. Equipped with an electronic expansion valve and high-performance components, the recently launched DYNACIAT range of compact water-to-water heat pumps is highly energy-ecient, achieving a European Seasonal Energy Eciency Ratio (ESEER) of up to 6.22, and Seasonal Coecient of Performance (SCOP) of up to 6.37.
