Gas absorption heat pump rebates

Save energy, save money and reduce greenhouse gas emissions with high-efficiency gas absorption heat pumps to provide space heating, domestic hot water and/or ventilation for your building. Our account managers and energy solutions managers are here to answer your questions and help you get rebates to reduce the upfront cost of this innovative heating technology. 


  1. You must be a FortisBC natural gas customer under any rate class except Rate 1.
  2. You must be a property owner or long-term leaseholder of an existing commercial or industrial building.
  3. The building must have dedicated outdoor space (ground level or rooftop) to house the gas absorption heat pump unit(s).
  4. You must submit an application and supporting documentation no later than 365 days after the purchase date of the product(s) (as shown on the paid invoice) or installation date (as listed on the application form), whichever is first.

Review all the terms and conditions.

What’s a gas absorption heat pump?

Like conventional heat pumps, gas absorption heat pumps capture heat from the outdoor air and transfer it indoors for space heating, domestic hot water and/or ventilation. Using gas to transfer heat, rather than directly heating air or water, they can achieve energy efficiencies of more than 100 per cent.1 They can also operate on renewable and low carbon gases,such as Renewable Natural Gas.

Rebate details

To help you determine if a gas absorption heat pump system is a fit for your building or facility, and to reduce the cost of installation, the program offers both feasibility study funding and product rebates.

Feasibility study funding

FortisBC can provide up to $20,000 in feasibility study funding to help with the cost of having a detailed engineering analysis performed. You’ll need to work with your engineering consultant to submit a feasibility study proposal to FortisBC to apply for this funding.

The feasibility study proposal should clearly define the scope and cost of the feasibility study, including:

  • a brief description of the facility, including location, site contact and overview of operations
  • a brief description of the gas absorption heat pump(s) and any additional condensing boiler(s) and/or condensing water heater(s) and controls to be studied
  • the proportion of the facility’s natural gas and/or electricity consumption that the system being studied consumes
  • pre-study estimates of heat pump cost and energy savings
  • methods used to estimate or model energy savings
  • an overview of any previous studies or work that has identified the heat pump as an opportunity to improve the energy efficiency of the facility
  • the name of the lead individual who will be responsible for conducting the feasibility study and completing the report
  • the total estimated feasibility study cost, including itemized costing broken down by job role, named individual, hourly rate, anticipated number of hours and budgeted expenses (such as travel)
  • a list of data and metering points required to complete the feasibility study and expected limitations on the scope of study

Product rebates

75% of the total project costs, up to $200,000, are available for installing gas absorption heat pumps in commercial, multi-unit residential or institutional buildings.

Which gas absorption heat pumps are eligible for a rebate?

Gas absorption heat pumps from manufacturers including, but not limited to, the following are eligible for rebates:

If you have questions about rebate-eligible heat pumps, contact us.

How to apply

  1. Work with the engineering consultant of your choice to develop a feasibility study proposal for a gas absorption heat pump for your building or facility, including the information outlined above, and submit the proposal to FortisBC. We’ll review it, and if approved, you may proceed with the full feasibility study.
  2. Submit the completed feasibility study and the paid invoice from your consultant to FortisBC to receive feasibility study funding.
  3. Before you buy a gas absorption heat pump, ensure it's eligible for the rebate. If you have questions, contact us before purchasing and installing equipment.
  4. Have a gas or mechanical contractor licensed with Technical Safety BC install your heat pump system. You can find one through our Trade Ally Network.
  5. Complete a gas absorption heat pump rebate application within 365 days of the purchase date (as shown on the paid invoice) or installation date (as listed on the application form), whichever is first. Be sure to provide copies of the fully paid invoice including make and model number of the eligible heat pump(s) purchased and installed.

1As reported in 2021 measurement and verification results for FortisBC’s gas absorption heat pump pilot program, in which Robur-A gas absorption heat pumps were installed for domestic hot water heating at seven sites in BC.

2FortisBC uses the term renewable and low-carbon gas to refer collectively to the low-carbon gases or fuels that the utility can acquire under the Greenhouse Gas Reduction (Clean Energy) Regulation, which are: Renewable Natural Gas (RNG or biomethane), hydrogen, synthesis gas (from wood waste) and lignin. FortisBC’s renewable and low-carbon gas portfolio currently includes only Renewable Natural Gas. Other gases and fuels may be added to the program over time. Depending on their source, all of these gases have differing levels of lifecycle carbon intensity. However, all of these gases are low-carbon when compared to the lifecycle carbon intensity of conventional natural gas. The current burner tip carbon intensity of RNG is 0.29gCO2e/MJ and the current RNG portfolio lifecycle emissions are -22gCO2e/MJ. This is below B.C.’s carbon intensity threshold for low-carbon gases of 36.4 gCO2e/MJ set out in the 2021 B.C. Hydrogen Strategy.
