Geothermal Energy
Frequently Asked Questions
- Can a geothermal system be installed only in a new house?
- No. Both customers who are having a house built and customers who already own a house can opt for a geothermal system. So it is an option that you may want to consider if you need to buy a heating and air-conditioning system to replace an old one. For more information about the work involved and things to consider, talk to a contractor accredited by the Canadian GeoExchange Coalition and your municipality If your existing house already has a distribution system (ductwork), that will facilitate the work greatly and lower the costs.
- What is the payback period for a geothermal system?
-
As geothermal heat systems are customized for each house, the payback period differs from one case to another. Essentially, the following points impact the payback period:
- If the system is installed when the house is being built or renovated (earth-moving work, limited access, etc.)
- System cost and type of system.
- Area of house to be heated and cooled (the bigger the area, the greater the savings on heating).
- Quality of thermal envelope.
- Age and type of heating and cooling system in place before installation of the geothermal system, in the case of an existing house.
- Type of ground.
- Is it absolutely essential to have a forced-air system with a geothermal system?
- No. A hydronic (water) system can be used for heating (radiant heat or other), but it does not allow for air-conditioning. Of course, air ducts may be installed.
- Am I eligible for a grant even if construction on my house began before the geothermal program was announced?
- You are eligible as long as the geothermal system is installed after May 1, 2007, and it is
CGC-certified.*This information appears on the certificate. Other conditions apply.
- Can I get a $2,800 grant for a geothermal system if I'm building my own house?
- Yes, as long as installation of the geothermal system is CGC-certified and the other eligibility criteria are met.
