How deep do ground source heat pump loops go in Ottawa?

Ground source heat pump loops in Ottawa typically go 150-200 feet deep for vertical installations, or are buried 6-8 feet deep for horizontal loops. The depth depends on your property size, soil conditions, and heating/cooling requirements.

Vertical loops are the most common choice in Ottawa due to our smaller urban lots. These systems drill straight down into the ground, with each borehole typically reaching 150-200 feet deep. Some larger homes may require depths up to 300 feet or multiple boreholes. The advantage is minimal yard disruption - you only need about a 10x10 foot area for the drilling equipment to access your property.

Horizontal loops require much more space but are less expensive to install. These loops are buried 6-8 feet deep (below the frost line in Ottawa) and need approximately 1,500-3,000 square feet of yard space depending on your home's size. The excavation covers a large area but isn't as deep as vertical drilling.

Ottawa's soil conditions generally work well for ground source systems. Our clay-heavy soil provides good thermal conductivity, though rocky areas may increase drilling costs. The ground temperature at these depths stays consistently around 8-10°C year-round, which is what makes geothermal so efficient in our climate.

Installation costs in Ottawa range from $20,000-$35,000 for a complete ground source heat pump system, with vertical loops typically costing $3,000-$5,000 more than horizontal due to the specialized drilling equipment required. TSSA requirements may vary for the installation - confirm permit requirements with your licensed HVAC technician.
