Dairy Farm Pre-Heat with Heat Pump

Water heating costs on dairy farms can often exceed £5,000 per year, particularly when relying on traditional immersion heaters, which are typically inefficient and energy-intensive. By contrast, an air source heat pump offers a far more efficient solution, capable of generating three to four units of heat energy for every unit of electricity consumed, delivering significant cost savings.

In this application, the heat pump is used as a pre-heating system, raising the water temperature before it is boosted to the required 90°C for hot washes. This final temperature is achieved using existing equipment, such as a Cotswold or Springfield dairy heater, allowing the farm to retain its current setup while significantly reducing overall energy demand.

Where the farmhouse is located close to the dairy, additional efficiencies can be achieved. Global Energy Systems’ technology enables the simultaneous production of heating and hot water at no extra cost. This means that while the heat pump is pre-heating water for the dairy, it can also provide hot water for the farmhouse, further reducing energy consumption and delivering additional savings for the farmer.

Overall, this approach provides a practical and cost-effective way to modernise dairy operations, improving energy efficiency while working seamlessly alongside existing systems.
