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.


  • Co-funding is for buildings classified as commercial or industrial – not residential or those owned by central government.
  • Total project cost must not exceed $150,000.
  • Co-funding is limited to a maximum of 50% of eligible project costs.
  • Total heat pump capacity must be at least 15kW (either a single unit or combination of units)

EECA is not making new financial commitments or entering into contractual arrangements related to the GIDI Fund at this time. Check back for updates.

What kind of project is it for?

The programme 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, from workplaces to indoor cropping.
  • Combined space and water heating (as above).
  • Approved installers can advise on the best system and eligibility for funding.

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

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.

  • 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.
