Progressive borders farm sets the wheat from the chaff with innovative heat/chill system Despite a pandemic causing havoc the length and breadth of the country, Calibrate Energy Engineering have successfully installed one of the largest ground source heat pumps (GSHP) in the country for a forward-thinking agricultural client, WL Douglas & Sons in Berwick-upon-Tweed. To showcase this substantial system, they are inviting rural and agri-businesses and other interested parties for an Open Day on 24th June so they can see first-hand the difference this technology can make. Calibrate have been designing, installing and maintaining commercial heat/chill systems for over 17 years and have identified a real need for their technology in high energy-use industries such as agriculture, food and drink processing, chemicals and waste management.
The installation of the latest 6.2mW GSHP came about due to the success a previous Calibrate 1mW system installed 3 years previously. The original was the first-of-its-kind to provide simultaneous heating and chilling and has now been joined by a further upgrade with capacity to dry one of the largest tonnages of grain of any GSHP in the UK. The results speak for themselves with the new system delivering 400% efficiency for heating at 45°C, 325% for chilling at 1°c and a total energy efficiency of 725%. To put it into perspective, the new pump alone has capacity to heat 775 4 bed houses. The system enables reduced fossil fuel usage and derives a high 20-year RHI tariff (the Government’s rebate programme for renewable technologies).
Managing Director for Calibrate, Gary Matthews, explains the background to this successful project: “Our customer, Ian Douglas, approached Calibrate in 2018 to look at ways they could speed up and streamline the grain
drying and cooling process and also reduce the company’s carbon footprint. Following an in-depth study, it was agreed that Calibrate’s 1mW heat pump heat/chill system was the perfect fit for their 40t/hr continuous flow grain drying system.”
Historic Bowhill House to be heated by one of Scotland’s largest ground source heat pumps The green credentials of a leading 19th century Scottish heritage attraction are set to be transformed by installation of one of the country’s largest ground source heat pumps. Bowhill House, a five-star mansion house on Buccleuch’s Borders Estate, is be heated by the ground-breaking wholly renewable energy system. A 24km pipe network is to be laid in the grounds of the estate, connecting the ground source heat pump to the house. The project, which is being delivered by borders-based company Renew Green Energy, will provide green energy for the house and surrounding buildings. 44
