Intelligent Hands Off Heatpump Systems
David and Peter Allan (RH & DH Allan) farm 2400 acres of arable land in the Scottish Borders growing a variety of commodities including; potatoes, swede, grain and oil seed rape. The installation of a 1996kw Ground Source Heatpump has enabled the business to reduce fossil fuel expenditure, increase efficiency of the existing business and also benefit from the 20 year RHI scheme.
Having designed the system with the client to ensure it was best suited to the individual needs of their business. 34,000m of underground pipe takes the heat that is naturally occurring in the ground and multiplies that through the Heatpump. Using a mixture of Heat Exchangers and Plate Exchangers, hot air and hot water is provided through a fully automated system. The pre heated air is directed into the grain dryer, drying floor and workshops. The hot water used for cleaning equipment provides 100% fossil fuel replacement all whilst also benefiting from the RHI scheme. This enables the client to maximise his cost savings by utilising the free by-product, chilling, to satisfy 80% of the chill load in the cold stores using a non-toxic glycol system.
