Smarter, cost-efficient equipment for businesses

The GIDI: Clean Tech Hot Water Heat Pumps programme offers up to 50% co-funding to help businesses replace and upgrade to cleaner, energy efficient equipment and lower energy bills.

Switching to reliable and proven ‘air to water’ hot water heat pump technology is quick and easy with EECA’s panel of experienced suppliers who will manage the whole process.

About the Hot Water Heat Pumps programme

Hot water heat pumps provide an energy-efficient, low-emissions solution to the traditional technology that commercial and industrial businesses use for their hot water needs.

EECA have a nationwide team of experienced hot water heat pump installers who can advise on the best system for your business’s current and future hot water needs, as well as whether your project qualifies for funding.

The programmes provides co-funding for ‘air-to-water’ hot water heat pumps that are used in commercial and industrial buildings to supply hot water for:

  • Heating water in places like kitchens, showers
  • Heating spaces of all types, for example, from work places to indoor cropping
  • Combined space and water heating (as above)

The programme is suited to sites that use a minimum of 1,500 litres of water per day and are replacing fossil-fuelled or inefficient electric boilers.

The business benefits of hot water heat pumps

  • High efficiency – Heat pumps are typically 3-5 times more energy efficient than natural gas boilers.
  • Low operating costs – Operating costs are typically around 25-35% of an electric resistance unit, or around 50% of an equivalent gas unit. Hot water heat pumps can reduce energy bills by 3-5 times.  
  • Safety and high durability – Heat pumps are reliable and they have built-in controls to self-regulate their operation.
  • Convenience – Hot water heat pumps are easily installed and avoid boiler house costs. Heat pumps can often use existing electricity supplies when retrofitted.
  • Avoidance of inflationary costs – Coal and gas are being phased out.

How the funding works

  • Co-funding is for buildings classified as commercial or industrial – not residential or those owned by central government.
  • Installers submit applications which can be made up of single units, or a combination of units, in any size - but must total at least 15 KW
  • ‘Air to water’ heat pumps that support water heating, space heating, and combined space and water heating for any end use purpose will be considered
  • Co-funding will be calculated based on water usage and efficiency of the new system.
  • Projects must be retrofits and come in under $150k.
  • Only registered suppliers/installers in the programme can offer co-funding to customers.

How to apply
