Water heating - Overview

Improve water heating energy efficiency by up to 56%

Our audits have shown that around 32% of the total energy used on a dairy farm goes into heating water for washing the milking equipment and milk vats.

Immediate savings on energy consumption can be realised by following these simple but effective energy savings tips:

• Insulate all hot water cylinders and pipes
• Repair any leaks and/or dripping taps
• Regularly check thermostat settings to ensure you're not over-heating the water

To make a significant reduction to your long-term operating costs, the best opportunities include:

• Utilising the warm water from the pre-cooler heat exchanger as supply for the hot water cylinders
• Installing a heat recovery system - either a de-superheater or a Mahana Blue™

Other options include:

• Solar water heating
• Heat recovery from the cleaning systems
• Heat recovery from the vacuum pump
