Opt for central heating with electric thermal storage and receive $6,500 in financial assistance from Hydro‑Québec
Less well known in Québec, electric thermal storage (ETS) is a technology that has been in use for a number of years in areas where dynamic pricing is available.
For a limited time only, Hydro‑Québec is offering financial assistance worth $6,500 to customers in a designated rollout area.
Transition énergétique Québec’s Chauffez vert program also offers subsidies that can help lower the cost of replacing your heating system. You can check with your municipality for further incentives as well.
Who is this technology for?
Central heating with electric thermal storage is for customers wishing to replace their fuel‑burning central heating system with an electric one, as well as those who need to invest in a new system.
- Live in the rollout area
- Own a single-family home (detached/semi-detached/row house)
- Be the owner-occupant of the house where the system is to be installed
- Have a forced-air central heating system powered by a fuel (dual-energy, oil, propane, natural gas)
- Have an easy-to-access basement with a concrete floor
- Be a Rate D or DT customer
- Have a communicating meter
- Have a Customer Space account on Hydro-Québec’s website

What’s the difference between common heating systems?
When there is a demand for heat, this type of system draws on heat that’s been stored in a thermal mass made from high-density ceramic bricks. These bricks are heated to a high temperature using electric elements. However, during peak demand events, the system is programmed to turn off these elements and the house is heated using only the stored heat. Result? During these short periods, you stay cozy and warm while using a lot less electricity during peak periods.
What’s more, with dynamic pricing (Rate Flex D), you can lower your electricity bill by reducing your electricity use during peak demand events, without any sacrifice to comfort.
When the temperature drops to a certain point, the thermostat activates the electric heating elements and fan to heat the house. A significant amount of electricity must therefore be used to keep the air warmed.
This type of system heats the air by drawing on two energy sources: electricity as the main source, and some form of fuel as the backup source. Most of the time, the house is heated when the thermostat activates the electric heating elements and fan. However, when the temperature reaches a specific threshold (based on the region), the system switches to the backup heat source, which runs on a fuel like oil, propane or natural gas. Since the electric heating elements are not in use at that time, you use much less electricity.
