Zeroth Energy System

This innovative system has been designed in conjunction with leading industry developers, recognising the need for a new, highly efficient communal solution for residential apartments.

The Zeroth Energy System takes a compact, in-apartment water source heat pump, low temperature (or ambient) energy loop and central plant to offer heating, hot water and comfort cooling to apartment developments as a commercially advantageous solution.
