How does a heat pump hot water system work?
A heat pump works like a refrigerator in reverse. It extracts heat from the air to heat water. Electricity is only used to operate the pump to move the heat; it is not used to create the heat.
For air sourced heat pumps that extract heat from the air, you will need to nominate the number of Small-scale Technology Certificates (STCs). You will also need to check if heat pumps with the nominated STCs are available at the location of the proposed dwelling. Information on the number of registered STCs of various heat pump models is available at the Clean Energy Regulator’s website.
For ground source heat pumps that extract heat from the ground, BASIX requires the system to be used for space heating or cooling. BASIX recognises ground source heat pumps for single dwellings only.
