Taking The Heat Out Of Farm Energy Costs

19 March 2010

UK - Installing a heat recovery unit (HRU) can help dairy farmers reduce water heating costs by up to 50 per cent by maximising the energy efficiency of milk cooling and water heating, according to DairyCo research.

An HRU is connected into the refrigeration system of the bulk tank, it takes the waste heat and uses it to pre-heat water before it enters the water heater.

An HRU can cost from £1,500 to £3,000, but with the financial savings to be made there will be a return on investment. Work by the National Farmers' Union and The Carbon Trust also means that a new interest-free loan has recently become available from The Carbon Trust to help farmers who want to invest in energy efficient equipment.

To calculate your water heating and milk cooling costs use the DairyCo energy calculators, available online at, or to find out about more ways of energy saving order the DairyCo booklet, Energy efficiency on farm, by calling 02476 478695.
