It’s 100% renewable energy, right under our feet. Geothermal energy uses natural heat from the ground to heat and cool buildings, without combustion or transportation— local and renewable energy. A few metres below the surface, the ground temperature remains relatively constant year round, around 10°C in Quebec. In the winter, a geothermal system extracts this free heat to heat the home, and in the summer, it pumps the building’s heat back into the ground to cool it.

No, Énergir’s geothermal solution* is available to everyone. So you don’t need to be close to the gas distribution system.

Yes, the drilling technology used to install vertical geothermal wells doesn’t require a lot of space and can be adapted to an urban environment.

Geothermal energy saves up to 60% on heating costs compared with a traditional system. By using free heat from the ground, geothermal heat pumps can achieve energy efficiency of up to 400% in some cases.

Geothermal energy benefits a wide variety of homes. Savings will vary according to a number of factors, such as how well the house is insulated, how many people live there, heating and cooling needs and so on. One of our experts can assess your energy needs to determine whether geothermal energy is right for you.

Geothermal energy does not make you completely self-sufficient in the event of a power outage. A small amount of electricity is required to operate the pumps. The heat pump can easily be powered by an alternative source of electricity on the Hydro-Québec grid, such as a generator or batteries, to keep you comfortable even when the power is out.

A geothermal system is very durable. It consists of a heat pump (installed in the mechanical room) and wells. The heat pump lasts up to 25 years, and the wells over 50 years.

To benefit from a geothermal system, you need a network of air ducts or a water network (hydronic heating). Unfortunately, you can’t make the shift to geothermal energy with electric baseboard heaters. You’d have to make a major investment to install air distribution ducts in every room of your home.

Drilling is done vertically, so it requires limited space. Once drilling is complete, the site will be cleared of all drilling residues and the work area will be resurfaced.

Permits vary by municipality but generally include authorization for drilling. We can assist you with this process.

The cost of a geothermal system includes the cost of drilling the wells, as well as purchasing, installing and connecting the geothermal heat pump to the wells. Although geothermal energy is more expensive than installing a standard heat pump, Hydro-Québec subsidies significantly reduce the system's cost. Additionally, savings of up to 60% on heating costs allow for a quick return on the additional investment in geothermal energy
