Outcomes of consultation on heat pump water heater fact sheet requirements

Consultation on proposed new heat pump water heater fact sheet requirements under the Energy Savings Scheme has ended.

To help customers make informed decisions ACPs (or their installers) will be required to give residential and business customers a copy of the relevant HEER or IHEAB heat pump water heater fact sheet before the customer agrees have a heat pump water heater installed.

We will ensure that ACPs have sufficient time to get ready to implement the change. We expect to commence the requirement in the first quarter of 2024.

We will tell you when we have published the fact sheets and guidance and confirm the commencement date of the requirements.

See our Past consultations page for more details including the consultation paper, submissions and What we heard document.

Multiple water heater installations and calculations

This guidance sets out when multiple heat pump hot water systems may be installed in the Energy Savings Scheme’s Home Energy Efficiency Retrofits (HEER) method and Installing High Efficiency Appliances for Business (IHEAB) method and the Peak Demand Reduction Scheme’s Reducing Demand Using Efficiency (RDUE) method. It includes example calculations for HEER, IHEAB and RDUE water heater activities, including the correct data to use to determine the capacity factor for Activity Definition F16 (IHEAB).

The guidance also sets out how multiple heat pump water heaters may meet the equipment requirements for the relevant activity definitions in the IHEAB and RDUE methods.

See Notice 03/2023 for details.
