Hot water and steam systems

Industrial worker with steam and machinery

Hot water and steam systems use a lot of energy. It makes good business sense to run them more efficiently.

What’s on offer?

The NSW Government has a scheme that provides incentives for businesses to reduce their energy use. 

How does it work?

Contact an approved supplier as early as possible before you begin an upgrade project. The supplier will:

  • explain the process
  • get you the incentive.

You may need to measure the energy use of your hot water and steam system for some time before and after the upgrade. This can be done by submetering or checking your energy bills.

How much will I receive?

The more energy you save, the better the deal. Shop around with different approved suppliers to get the best offer.

Check to see if there is an approved supplier in your region:


By using the regional approved supplier lookup below you are agreeing to the terms of service.

Approved suppliers are known as Accredited Certificate Providers (ACPs). Information about ACPs is provided for general information only. The Independent Pricing and Regulatory Tribunal (IPART) is the Energy Savings Scheme Administrator and Regulator and is responsible for accreditation, auditing and compliance of ACPs. Before proceeding with engaging an ACP a customer should review up to date information available on the IPART website.

By accessing and using information about ACPs available on this website, the customer acknowledges and agrees:

  • the NSW Department of Planning, Industry and Environment (DPIE) does not have any legal liability whatsoever connected to the deliverables associated with this program, including any issues arising from interactions with ACPs and technology installations
  • to discharge DPIE from all actions, proceedings, claims, demands, costs, losses, damages, and expenses the customer may potentially incur through this program or arising from the use of this information for any other purpose.

How will this help my business?

Installing new equipment or modifying your hot water and steam systems can result in a big reduction in your energy bills and environmental impact.

What is a hot water and steam system upgrade?

An upgrade is when you replace equipment or modify an existing system so that it becomes more energy efficient.

Examples of modifications include, but are not limited to:

  • adjusting the controls on your system so your boiler runs only when needed
  • optimising boiler blowdown rate and control
  • installing heat recovery systems to utilise the low-grade waste heat in other applications
  • eliminating steam leaks and steam trap losses
  • minimising boiler/steam generator heat loss through better insulation.


Contact an approved supplier directly. 

The incentives are created through the NSW Energy Savings Scheme (ESS).
