Custom Designed Waste Heat Recovery System for Bruichladdich Distillery
‘Progressive Hebridean Distillers’ deploy a Waste Heat Recovery System, saving £7333 annually with a 3 year payback period.
Heat Recovery Technology has great potential to provide sustainability to the industrial sector, which represents around 20% of final energy consumption and more than 30% of heat-generated CO2 emissions within the UK. Additionally energy costs account for almost 40% of production costs within the most heat intensive industries. Therefore deploying a Waste Energy Recovery system has the potential to reduce production costs and improve competitiveness within these businesses.
Harnessing Waste Heat
The distilling process produces significant amounts of hot water which is usually stored in large distilling tanks with heat lost to the ambient air. Recognising this and that there was an opportunity to reduce heating costs for other parts of the distillery, Bruichladdich Distillery asked Ecoliving to look at a means of harnessing and redistributing the ‘waste’ heat.
Heat Exchange and Re-distribution
Ecoliving assessed the potential for waste heat to be used for heating and designed a system employing a heat exchanger together with an Effecta 750 litre cylinder. This was agreed and then installed by Ecoliving in 2013. The waste heat at approximately 80°C is captured and following the heat exchange process is distributed for hot water and space heating use in the Distillery Visitor Centre, bottling hall and meeting rooms.
Reducing Heating Costs and CO2 Emissions
The Ecoliving solution of harnessing the waste heat has meant 2 oil boilers at Bruichladdich Distillery are now redundant with a consequent saving in heating costs of approximately £7,333/ year and a carbon footprint reduction of 26,588 kgCO2/ year.
Carbon footprint calculation based on the assumption: 2013/14 kerosene heating oil price 70p/L.
“The service that Ecoliving provided from the very outset of this project has been exceptional. They initially came to the distillery and advised on how we could recycle some of the excess heat from the distillery, from there they designed a very efficient and cost effective way of heating our Bottling hall, Visitor centre and offices utilizing the excess heat. The installation was carried out to a very high standard and we found that Rory and Gavin and the rest of team at Ecoliving were extremely helpful.” Allan Logan, Distillery Manager
