Heat Recovery Toolkit

Recovering heat from drain water has been estimated to be financially viable for 90% of commercial kitchens in the UK. Apart from delivering savings in energy costs, it is also a great way of reducing greenhouse gas emissions from energy use and make kitchen operations greener, contributing to climate change mitigation targets.

As part of our research agenda for Drain Water Heat Recovery we have developed a Heat Recovery Toolkit, free to be downloaded. Our toolkit is specifically designed for commercial kitchens, including all types of food outlets, such as restaurants, pubs, cafés, or canteens, including catering in schools, universities, hospitals or care homes.

The heat recovery system considered in the toolkit uses a simple double walled copper pipe as heat exchanger for direct heat recovery – no heat pump needed. The heat exchanger is easy to install wherever a part of the kitchen drain pipe can be replaced and has been widely used for shower heat recovery, for which it was originally designed.

Users can learn about the potential heat recoverable from their kitchens, operational cost savings and installation costs, as well as the potential carbon emissions saved. Only little data required to get an individual estimate of how suitable a kitchen is for drain water heat recovery: data on water consumption or number of meals served and on the currently used energy for hot water.
