Heat Pump Overview

Hot Water generation using a Heat Pump is the most reliable, cost effective and efficient means of hot water production. Using standard reverse cycle air conditioning principals, heat pumps absorb free energy from the heat in the ambient air or water source. Heat pumps, unlike solar, can operate 24/7, day and night in temperatures ranging from –7 degrees celsius to 43 degrees celsius, ensuring hot water is delivered when required. New advances in compressor technology and materials used for heat exchanges and components ensure that these units deliver the highest efficiency and COP.


  • Safety

Model Applications

Direct Heating Air Source Heat Pump
  • High efficiency air source heat pumps produce water at the desired set point temperature, regardless of cold inlet water temperature.
  • Improved efficiency and thermal storage stratification.
  • No mixing of cold and hot water in the tank.

High Temperature Heat Pumps
  • Special application high temperature heat pumps can produce water temperature 75 – 80 degrees celsius.
  • Gas sub-cooling cycle allows for cooling of compressor to produce high temperatures for special applications

Geothermal / Water Source Heat Pumps
  • Water source heat pumps use water as a heat source, unlike air source heat pumps
  • Allows for special applications for heating water but also cooling source water
  • Can be linked into AC chilled water return or condenser water to pre-chill
  • Providing savings on hot water generation and air conditioning / HVAC systems
