Calor powered Rinnai Water Heaters – a smarter hot water heater for your farm and milking shed


Good hygiene in the milking parlour is essential to ensure a contamination-free milk – but how can you ensure your system is delivering what’s best for you, your animals, the farm and the end product?
This compact hot water solution from Calor could revolutionise your farm – reducing the need to store hot water and cutting costs – providing instant hot water at the right temperature to meet all regulations.
DAERA guidelines explain that milk can be contaminated at any point in the production process, and that it is the responsibility of the food business operator (milk producer) to identify these points and implement control measures to protect milk from contamination.
One of the key sources of bacterial contamination is from poor milking practices including soiled hands, soiled equipment and failure to clean and disinfect teats prior to milking or from inadequate cleaning and disinfection of milking equipment and bulk milk containers.
DAERA recommends that cleaning systems equipment should be kept clean during milking - including circulating hot water washes at specific temperatures.
But how can you ensure that you have enough hot water, at the right temperature to be certain that your animals, buildings and equipment are not just clean but hygienically and safely clean?


Calor has the answer
Calor’s instant hot water solution provides farms with unlimited hot water for milking parlours, calf rearing mixing, farmyard cleanliness and general hygiene, supporting best practices and quality milk production.
The compact design of the Rinnai Water Heater means it is simple to install and house.
The system only heats water when required, so there is no need to heat or store hot water in advance – removing the need to set up bulky storage systems and the worry of running out of hot water. Of course, this then helps with fuel efficiency and reducing overheads.
These heaters offer adequate washing volume, providing enough hot water for each wash and reducing the risk of bacterial contamination.
Sufficient rinse water is essential for removing cleaning agents and residues, leaving the equipment clean and ready for the next milking session.
DAERA recommendations
The Department for Agriculture recommends for ensuring optimal hygiene and safety in the milking parlour.
The external surfaces of the milking equipment, including jetters, clusters and milk pipes should be washed and the plant is set up for cleansing.
Circulate a hot wash using an alkaline detergent steriliser, circulated for a minimum of 5 minutes and a maximum of 10 minutes. Use 10-15 litres of water at 85°C per milking unit. Water temperature should be not less than 50°C at the end of circulation
A hot wash must be carried out at least once a week using hot caustic solution at a starting temperature of 85°.
