Heat pumps for major grower

A 1.9MW heating system powered by CIAT ground-source heat pumps is providing low-cost, low-carbon renewable heating for Coletta & Tyson,

one of Europe’s largest independent nurseries.

Coletta & Tyson is 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.

Ebtech’s design is based on three DYNACIAT water-to-water units, supplied by Cool Systems Distribution Ltd, linked 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 450mm, 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.

Radiators help college comfort

Opened in 2020 the Falkirk Campus building of Forth Valley College in Scotland, offers an excellent environment for learning. Included in this new campus is a well-designed heating system to ensure students and staff were comfortable at all times of the year. Key to the heating system was the use of Stelrad radiators throughout the campus – a mix of more than 300 Stelrad Planar radiators –– both horizontal and vertical models – alongside 40 Concord Lo-Line floor mounted radiators and several of Stelrad’s best-selling range of low surface temperature radiators.

Specification was secured via consultants K J Tait and Balfour Beatty Kilpatrick was lead contractor on the project. The radiators were supplied via the local Wolseley branch.

“We were delighted to see our radiators specified for inclusion in this prestigious project,” said Stelrad’s head of marketing, Chris Harvey. “We have seen our radiators selected for an increasing number of large-scale, education related projects in schools, colleges and universities across the UK in the past couple of years. This building is leading edge and highlights how well our radiators can contribute to comfort in larger commercial properties that require efficient sharing of heat around the premises."
