Installed System Costs by Type
Heated driveway pricing varies significantly based on system type, surface material, and site conditions. The figures below represent typical installed costs for the Renfrew County region, including materials and qualified contractor labour.
Electric Mat System — Under Concrete
$10–$20 per square foot installed. Pre-spaced electric heating mats are laid on the prepared sub-base and embedded in the concrete pour. This is the most common residential approach. Total cost for a standard two-car driveway (approximately 400 square feet): $4,000–$8,000 for the heating system and electrical work alone, separate from concrete work.
Electric Mat System — Under Interlock or Pavers
$15–$25 per square foot installed. Installation under interlocking pavers is more labour-intensive: mats are embedded in the sand/concrete bed beneath the pavers, which are then reinstalled on top. The higher cost reflects the extra handling of pavers and the precision required to protect the system during installation.
Hydronic System — Under Concrete
$20–$35 per square foot installed. Flexible PEX tubing is laid on the sub-base, connected to a manifold, and embedded in the concrete slab. A dedicated or shared boiler circulates heated glycol-water mixture through the tubing. For a 400 sq ft driveway, expect $8,000–$14,000+ for the heated system components and installation — before the boiler if one is not already in place.
Hydronic Boiler (if not existing)
If a dedicated boiler is required for the hydronic system, add $3,000–$8,000 depending on boiler type, capacity, and whether natural gas or propane is used. Properties with an existing hydronic heating boiler may be able to use spare capacity, significantly reducing this cost component.
Additional Cost Factors
Concrete or Paving Replacement
A heated driveway requires a new driveway surface — radiant heating cannot be added to an intact existing slab or paved surface. If your driveway needs replacement regardless, this cost is shared. If the driveway is otherwise serviceable, adding radiant heat means you are paying for a complete driveway replacement you may not have budgeted. Concrete replacement typically adds $8–$15 per square foot to the project.
- Demolition and removal of existing driveway: $2–$5/sqft
- Gravel sub-base preparation: included in most paving quotes
- Concrete pour (4–6 inch slab): $6–$12/sqft
- Asphalt alternative: $4–$8/sqft (note: asphalt is less common for heated driveways as it retains less heat)
Automatic Sensor and Controller
A moisture and temperature sensor controller automatically activates the system only when it detects precipitation at cold temperatures. This is strongly recommended — it prevents the system from running during dry cold spells and substantially reduces operating costs. Budget $300–$800 for an automatic aerial sensor and controller unit, plus installation labour.
Electrical Panel Upgrade
Electric heated driveways require a dedicated circuit sized for the system load. If your panel is already at or near capacity — common in older Renfrew County homes — an upgrade may be needed. A 100A to 200A panel upgrade typically costs $2,000–$4,000 with a licensed electrician, including the ESA permit.
Operating Costs
Electric System
Electric heated driveways draw 15–50 watts per square foot depending on mat density and design. For a 400 sq ft driveway running at an average of 20W/sqft:
- Total draw: approximately 8 kW
- Cost per hour at Ontario's average rate (~$0.17–$0.22/kWh): $1.36–$1.76 per hour
- With automatic sensors, active run time in a typical Renfrew County winter: approximately 100–150 hours over the season
- Estimated seasonal electricity cost: $136–$265
Manual timer control (no sensor) dramatically increases costs because the system runs during dry periods. An automatic sensor is the single most effective way to reduce operating costs.
Hydronic System
Hydronic operating costs depend heavily on boiler efficiency and fuel type. Per-hour cost while running is typically lower than electric for large areas, but the boiler itself has an idle load and periodic maintenance requirements. For most residential driveways under 600 sq ft, the operating cost advantage of hydronic rarely justifies the higher installation cost — it becomes cost-effective at larger scales or when integrating with an existing hydronic system.
Sample Project Totals
- Electric under concrete, 400 sqft driveway (new construction): ~$6,000–$11,000 total (heating system + electrical + concrete)
- Electric under concrete, 400 sqft driveway (replacing existing): ~$9,000–$16,000 total (add demolition + concrete replacement)
- Electric under interlock, 400 sqft: ~$12,000–$18,000 total
- Hydronic under concrete, 400 sqft, existing boiler: ~$11,000–$18,000 total
- Hydronic under concrete, 400 sqft, new boiler: ~$14,000–$26,000 total

Ontario Grants and Rebates
No dedicated Ontario or federal grant program currently covers heated driveway installation. The Canada Greener Homes Loan, Ontario Home Efficiency Rebate Plus (HER+), and Oil to Heat Pump Affordability Program (OHPA) all focus on home energy efficiency measures — insulation, windows, heating systems — and do not include outdoor driveway heating.
If the heated driveway is being installed as part of a substantial, qualifying home renovation project, the HST renovation rebate may apply to portions of the project. This is not a direct grant — it reduces the amount of HST paid on qualifying renovation work. Consult a tax professional to determine whether your project scope qualifies.
