On average the daily hot water consumption in a dairy shed is between 300 and 900 litres. For 900 litres, the annual energy cost is approx. $8,000. A hot water heat pump can bring that cost down by at least 50% (and up to 65%)! With ever increasing energy prices it is worth investing in an energy efficient and economical system as an alternative to the standard electric or gas heating.​

The Calitec high-temperature heat pump hot water system is a mono-block system with the heat exchanger built inside the stainless steel case. This system heats the water by circulation pipes to and from your water cylinder. Heat pump technology is reliable in all New Zealand weather conditions.


The system is compatible with solar hot water heating options and one heat pump unit can heat up multiple cylinders.​
