Heat recovery units on dairy farms

Published 8 October 10

This technical note covers work funded by the Milk Development Council, SWEB and PowerGen to provide independent, up to date information about the application and cost benefits of heat recovery units (HRU's). The heat recovery process involves the transfer of 'waste' heat from the refrigerant of the milk cooling system into water. The water is pre-heated by the refrigerant before it enters the dairy water heater, where the temperature is 'topped up' using the existing immersion heater.
