A Model Geothermal Heating Installation on the South Shore: Efficiency, Durability, and Outstanding Thermal Comfort
As part of our commitment to offering sustainable and high-performance HVAC heating solutions in the Greater Montréal area, we recently completed a residential geothermal heating installation on the South Shore, specifically in Saint-Lambert. This article shares that experience, rich in technical challenges, remarkable results, and long-term benefits for our client. Thanks to our personalized approach, our expertise in geothermal systems, and our deep understanding of Québec’s climate, this project turned out to be a clear demonstration of the real benefits of residential geothermal energy.
Why Choose a Geothermal Heating System on the South Shore?
Homeowners on the South Shore of Montréal, especially in cities like Brossard, Longueuil, or Saint-Lambert, are increasingly seeking eco-efficient, reliable, and stable heating solutions to cope with Québec’s harsh winters. Geothermal heating stands out as an ideal option, offering:
-
Energy savings of up to 70% compared to traditional heating systems.
-
A significant reduction in GHG emissions, ideal for households concerned about their environmental impact.
-
Consistent indoor comfort, year-round, thanks to stable temperature regulation.
The Installation Context: A Family Home in Saint-Lambert
This project involved a 2,400 sq. ft. single-family home with an old oil-based central heating system. The homeowner was looking for a solution that was eco-friendly, long-lasting, and cost-effective. After a full evaluation of the home—including thermal loss testing and a land survey—we recommended a vertical geothermal system with a high-efficiency central heat pump.
The System Installed: Performance, Efficiency, and Available Grants
For this project, we installed a Bosch SM Rev C central geothermal heat pump, model SM060, offering:
-
60,000 BTU/h, ideal for a home of this size.
-
Coefficient of Performance (COP) of 4.7, exceeding Canadian energy efficiency standards.
-
Eligibility for significant financial grants: this model qualifies for assistance through Hydro-Québec’s LogisVert program, up to $5,000, and the Rénoclimat program.
The client received a total of $7,200 in grants, significantly reducing their upfront investment.
Installation Steps: Precision, Coordination, and Professionalism
1. Geothermal Analysis and Drilling
We began with a certified geothermal study to determine optimal depths. Two vertical wells of 150 feet were drilled in the backyard, fully compliant with environmental regulations and site constraints. High-density polyethylene pipes were inserted and filled with heat transfer fluid.
2. Indoor Installation
The Bosch central heat pump was installed in the basement and connected to the existing ductwork via a new high-performance air handler. A system of smart thermostats was integrated, allowing for room-by-room control.
3. Commissioning and Testing
Our certified technicians conducted thorough flow, pressure, and performance tests, confirming optimal thermal efficiency from day one. The system is quiet, stable, and delivers smooth heat even in -20°C conditions.
Results Achieved: Performance Beyond Expectations
Just a few weeks after installation, the homeowner reported:
-
A reduction of over 65% in energy consumption compared to the old system.
-
Consistent thermal comfort throughout the home, with no cold spots or mechanical noise.
-
High satisfaction with the ease of use, especially via the connected thermostats.
Challenges Faced and Solutions Implemented
As with any geothermal heating installation on the South Shore, some technical challenges arose:
-
Limited space: The narrow lot required precise coordination with the drilling team to place the wells without affecting existing infrastructure.
-
Ductwork adaptation: We had to reconfigure some air ducts to optimize airflow to distant rooms.
These challenges were met thanks to our team’s expertise and meticulous planning, backed by over 15 years of experience with complex HVAC installations in Montréal and surrounding areas.
