The EasiHeat steam-to-hot-water system provides hot water for staff at the company’s production facility in Worksop. The site produces 3.5 million packs of handmade sandwiches, baguettes and wraps each week and staff must adhere to a rigorous daily hand-washing regime. 

EasiHeat is based around a compact plate heat exchanger and provides instantaneous hot water at constant temperatures. Spirax says that because it does not store water like a traditional shell-and-tube storage calorifier, which must store water at 60°C or higher to aid the prevention of Legionella growth, less energy is needed to heat the water. 

Further savings will be achieved by reduced maintenance costs as the EasiHeat system does not need dismantling for insurance inspections.
