At Miller’s Dairy they milk about 130 Jersey cows, twice a day. Milk is pumped from the milk tank in the barn, underground to a milk tank in an on-farm milk processing plant. In the plant, they make skim milk, 2% partly skimmed, chocolate milk and various cream products including cream sold to produce ice cream.
Their products are bottled in glass bottles which are returned, cleaned and reused. All this milking equipment in both the barn and milk processing plant takes over 3500 litres of hot water per day.
An 18-collector 30-tube S-Power heat-pipe solar water heating system was installed on the plant along with 3 A.O. Smith hot water storage tanks. Excess hot water from the Milk Plant is pumped underground to the Milk House to 2 Baxi storage tanks used for washing milk tanks, pipelines and milking equipment in the barn.
