Switch to dual energy before the cold weather arrives
Dual energy combines electricity and natural gas to heat your home: electricity is used most of the time, while natural gas takes over during periods of extreme cold4.
By adding a compatible electric appliance and taking advantage of available grants1, you could complete your project at a lower cost and enjoy dual-energy heating as early as this winter.
What are the benefits for your situation?
Fall is the ideal time to upgrade your natural gas heating system. Whether your natural gas appliance is fairly new, midway through its service life or nearing the end of it, dual energy could offer benefits for your comfort, heating costs and the optimization of energy resources.
My natural gas heating appliance is fairly new | Less than 7 years old
My natural gas heating appliance is midway through its service life | 7 to 15 years old
My natural gas heating appliance is nearing the end of its service life | 15 years old or more

FAQ
The electricity–natural gas dual-energy heating offer is intended for Énergir residential customers whose homes are equipped with a natural gas central forced-air or hot-water heating system. It is designed for homeowners who want to upgrade their heating system and optimize their energy use with a solution that combines electricity and natural gas.
Planning your project before the heating season helps you avoid the pressure of a rushed replacement in the event of a breakdown and increases your chances of finding an available specialized contractor. It also gives you more time to choose the right solution and could allow you to benefit from your new system and the dual-energy rate before winter arrives.
Yes. If your natural gas appliance is still in good condition, you can generally keep it and simply add a compatible electric appliance.
If, on the other hand, it is nearing the end of its service life, the conversion work is an excellent opportunity to replace it with a new-generation appliance, upgrade your heating system and improve its efficiency.
Eligible residential customers benefit from Hydro-Québec’s dual-energy rate (Rate DT) or the dual-energy rate offered by their electricity distributor. This advantageous rate generally lowers the cost of electricity when the outdoor temperature is above the switchover temperature (-12°C or -15°C, depending on the region). When the temperature falls below this threshold, the system automatically switches to natural gas to heat the home.
The dual-energy rate applies to all electricity used in your home throughout the year.
To start your dual-energy project, contact Énergir to verify your eligibility and receive free quotes from Énergir Partners. These contractors are familiar with dual-energy requirements and can assist you at every stage of the project, including assessing the required work, presenting compatible equipment and applying eligible grants directly to your invoice, where applicable.
You may also hire a contractor of your choice who is not an Énergir Partner.
Forced-air heating : A furnace or forced-air generator, air ducts, and vents in the floor, walls or ceiling.
Hot-water heating : A boiler, radiators, hydronic baseboards or a network of pipes that distributes hot water throughout the building.
