Energy Efficiency program — effective diagnosis and implementation
Optimizing boiler systems
Apply today for one or more subsidies to increase the efficiency of boilers producing steam or hot water from natural gas. With more efficient boilers, you’ll get more heat, consume less natural gas, and ultimately emit less greenhouse gas.Savings for you, and benefits for the planet!
The four measures for optimizing boiler systems
The four measures for optimizing steam or water boilers systems eligible for the grant are:
- Installing an economizer
- Installing a micromodulation system
- Installation of an O2 probe
- Installing thermal insulation on equipment and accessories
More than one measure can be combined in a single grant request1.
Installing an economizer
Installation of a micromodulation system
Install a combustion oxygen trim
Installation of thermal insulation
A grant may be provided for installing an economizer on a new or existing steam boiler. It can be installed on the stack or directly integrated into the boiler.
The economizer recovers heat from hot fumes vented into the atmosphere, increasing the efficiency of the boiler by 85% or more.
A grant may be provided to equip an existing water or steam boiler with a micromodulation system.
The micromodulation system allows for advanced control of combustion performance by adjusting the air/fuel ratio in the burner.
Installing a combustion oxygen trim probe to an existing water or steam boiler with a micromodulation system may be eligible for a grant.
Adding a combustion oxygen trim probe to a micromodulation system adjusts the ratio of air to fuel in the burner, taking into account variations in boiler conditions (pressure, temperature, humidity, etc.). The probe will enhance the micro-modulation system.
A grant is available for installing thermal insulation on equipment and accessories (valves, tanks, etc.) to reduce heat loss.

Renewal natural gas: your decarbonization ally
Once your energy-efficiency measures are in place, you can replace part or all of your natural gas consumption with renewable natural gas.
RNG is 100% renewably-sourced energy that reduces your greenhouse gas (GHG) emissions without your needing to change equipment.
The terms and conditions of the program can be found on Form I – Conditions and Declaration of Intent (Before Work Starts).
The program may be changed without notice.
