Dairy hot water cost savings
switch to save up to 75%
Significant savings can be achieved by switching from traditional batch electrical water heating to an oil fueled water heating system as evidenced in Teagasc update 08/05/2020.
Adequate and regular use of HOT water is vital
“Nine litres of hot water with a starting temperature of 75°C-80°C per milking unit is required. The number of hot washes will depend on the protocol chosen and product type.
For example, seven hot washes per week is the minimum required with a liquid caustic detergent and four hot washes per week is the minimum required with a powder caustic detergent (fewer hot washes due to a higher caustic concentration of 76% in these powder products). The finish temperature of the detergent wash cycle must be at minimum 45°C to achieve good cleaning.”
