Curleys Supermarket

Energy Efficiency Solution: Thermosave Heat Recovery from Refrigeration System
Business Problem
Curleys supermarket is Northern Ireland’s largest independent supermarket retailer. The company consists of two supermarkets in Belfast and Dungannon, a petrol station and 13 off licenses throughout the province. In today’s business environment rising energy costs are a real issue and any business person will tell you that rising energy costs means less profit! Although Curley’s existing refrigeration system was operating within its design parameters, all of the heat generated by the system was simply 'dumped' in to the atmosphere.
Solution
The solution was to install the ThermoSave Heat Recovery System. This system offers an engineered solution that uses the waste heat from the Refrigeration system, converts it into hot water through a heat exchanger, which in turn provides space heating and domestic hot water. Conventional heat recovery systems typically recover between 30 and 40% of waste heat from the refrigeration plant however; the Thermo Save System collects virtually 100% of all waste heat making real savings.

"We are committed to the efficient use of resources by reducing the amount of energy we use. Supermarket requires," said Stephen Kennedy, Director.

"We are continually looking at ways to reduce the amount of energy, along with this highly effective measure of Heat Recovery we have also taken a number of simple solutions such as using energy saving bulbs, installing timers and switches that use motion detectors and using night blinds for the freezer units. For years now we have had clothes and bottle banks and we do recycle not only our own cardboard and plastic packaging but also used carrier bags that are returned to us. We have always felt a corporate responsibility and we look forward to working closely with Energia to reduce our energy usage as much as is possible" said Stephen.
