Accolade Heating provides ground source heat pump consultation and installation for Surrey-area properties. Geothermal systems deliver the highest efficiency of any heating technology — COP 3.5–5.0 — using the stable year-round temperature of the earth.
The ground at depths of 1.5–2 metres maintains a stable temperature year-round in BC — typically 8–12°C. Ground source heat pumps use a loop of fluid-filled pipes buried in the ground or in deep boreholes to access this stable temperature reservoir.
In winter, fluid in the ground loop absorbs heat from the earth and brings it indoors where it is amplified and distributed. In summer, the process reverses — excess heat is rejected into the cooler earth. Because ground temperature is far more stable than outdoor air, ground source systems achieve higher efficiency — particularly during extreme weather when air-source performance decreases.
Pipes buried 1.5–2 metres deep across a large area. Requires 500+ square metres of accessible land per ton of capacity. Most common for larger Surrey properties.
Pipes inserted into vertical boreholes 60–150 metres deep. Requires far less surface area — suitable for smaller lots. Higher drilling cost but minimal landscape disruption after installation.
Is ground source right for your property? Ground source has significant upfront costs versus air-source. It is best suited to new builds, major renovations, or properties where the higher efficiency justifies the investment over a 20–25 year lifecycle. We give you an honest comparison in every consultation.
| Ground Source | Air-Source (Ductless or Ducted) | |
|---|---|---|
| Efficiency (COP) | 3.5–5.0 year-round | 2.5–4.0 (varies with outdoor temp) |
| Upfront cost | Significantly higher (drilling / excavation) | Moderate — comparable to furnace + AC |
| Payback period | 15–25 years typically | 7–12 years typically |
| Property requirement | Lot space for loops or boreholes | Outdoor unit space only |
| CleanBC / federal rebates | Federal programs available | ✓ Up to $6,500 CleanBC |
| Best for | New builds, major renovations, large properties | Most Surrey residential retrofits |
Our honest guidance: For most Surrey residential retrofits, a cold-climate air-source heat pump delivers excellent performance with faster payback and higher available rebates. Ground source makes the most sense for new builds, properties with planned major renovation, or owners with specific long-term energy goals. We explain both in every consultation — we do not upsell ground source where air-source is the better choice.
"James installed and has been servicing our Furnace, Central AC and Tankless water heater. His attention to detail, level of transparency, and dependability each year has been greatly appreciated."
"After 12 years of having James maintain, repair and install anything required for our gas, heating and plumbing needs, I continue to highly recommend him. Professional, incredibly thorough, educates us every step."
"I can't recommend James enough. He took on an extremely difficult job with our home's heating system. Most other plumbers flat out refused the job. James turned a nightmare scenario into a perfectly functioning system."
Tell us your property type, lot size, current heating system, and whether this is a new build or retrofit. Our heat pump specialist responds within one business hour.
