Converting from Oil to Electric Heat in New Brunswick
With oil prices volatile and heat pump technology improving, many NB homeowners are considering switching away from oil. Here's what the conversion involves electrically, what it costs, and which electric heating option makes the most sense.
Option 1: Oil → Heat Pump (Recommended)
A heat pump is the clear winner for most NB homes converting from oil. It uses electricity but delivers 2.5–3.5 times more heat per kilowatt than direct electric heating.
Mini-split (ductless) heat pump:
- Best for: Homes without existing ductwork, supplementing remaining oil furnace, single-zone or multi-zone heating
- Electrical needs: Dedicated 240V, 20–30A circuit per outdoor unit, plus disconnect switch
- Keeps existing oil furnace as backup for extreme cold snaps (below -25°C)
- Cost: $3,500–$7,000 per zone installed (before NB Power rebates)
- Operating cost: ~$800–$1,200/year for a 1,500 sq ft home (vs. $2,500–$4,000 for oil)
Central ducted heat pump:
- Best for: Homes with existing ductwork (replacing the oil furnace entirely)
- Electrical needs: Dedicated 240V, 30–60A circuit for the heat pump, plus 240V circuit for electric backup heat strips in the air handler
- Removes oil tank and furnace completely
- Cost: $8,000–$15,000 installed (before rebates)
- May require a panel upgrade if your panel can't handle the additional 40–80 amps
Electrical requirements for heat pump conversion:
| Component | Circuit Needed | Cost |
|-----------|---------------|------|
| Mini-split outdoor unit | 240V, 20–30A dedicated | $400–$1,200 |
| Central heat pump | 240V, 30–50A dedicated | $500–$1,500 |
| Air handler with backup strips | 240V, 30–60A dedicated | $500–$1,500 |
| Disconnect switch | Required by CEC | Included in above |
| Panel upgrade (if needed) | 100A → 200A | $2,500–$4,500 |
| TSANB permit | Required | $50–$100 |
Option 2: Oil → Electric Baseboard
Replacing an oil furnace with electric baseboard heaters is simpler but significantly more expensive to operate than a heat pump.
When baseboard makes sense:
- Budget is very tight and you can't afford a heat pump upfront
- You're converting a small space (cabin, cottage, single room)
- As supplementary heating in zones the heat pump doesn't reach
Electrical requirements:
A full baseboard conversion for a 1,500 sq ft home requires:
- 10,000–15,000 watts of installed baseboard capacity
- 4–8 dedicated 240V circuits (each circuit serving 2–3 heaters)
- Individual thermostats for each zone
- Almost certainly a panel upgrade to 200A
| Component | Cost |
|-----------|------|
| Baseboard heaters (8–12 units) | $400–$1,200 |
| New 240V circuits (4–8) | $1,600–$4,800 |
| Thermostats (6–10 zones) | $300–$1,000 |
| Panel upgrade (likely needed) | $2,500–$4,500 |
| TSANB permit | $75–$150 |
| Total electrical | $4,875–$11,650 |
Operating cost: ~$2,000–$3,500/year — often similar to or more than oil, depending on oil prices.
Option 3: Oil → Electric Boiler (Hydronic)
If your home has hot water radiators or in-floor radiant heating fed by the oil boiler, an electric boiler is a direct replacement.
Electrical requirements:
- Dedicated 240V circuit, typically 40–100A depending on boiler size
- Very likely requires a panel upgrade
- Some homes may need a 400A service or a second panel
Cost: $3,000–$8,000 for the boiler plus $2,500–$6,000 for electrical.
Operating cost: Similar to baseboard — electric resistance heating rates apply.
Panel Capacity: The Critical Question
Most oil-heated NB homes have 100A panels because oil furnaces draw minimal electricity (just the fan motor and ignitor). Converting to any form of electric heating adds substantial electrical load:
| Heating Type | Additional Amps Needed |
|-------------|----------------------|
| Mini-split heat pump (1 zone) | 15–30A |
| Central heat pump + backup strips | 50–80A |
| Full baseboard conversion | 60–100A |
| Electric boiler | 60–100A |
A 100A panel serving a home with an electric dryer (30A), electric stove (50A), hot water tank (20A), and general loads (30A) is already at 130A theoretical demand. Adding 30–80A of heating load pushes well beyond capacity.
Bottom line: Most oil-to-electric conversions in NB require a 200A panel upgrade. Budget $2,500–$4,500 for this on top of the heating conversion costs.
Oil Tank Removal
Once you're off oil, the tank should be removed:
- Indoor tank removal: $500–$1,500 by a licensed oil technician
- Underground tank removal: $2,000–$5,000+ (includes soil testing for contamination)
- NB regulations require proper decommissioning — you can't just abandon it
NB Power Rebates
NB Power's Total Home Energy Savings Program has offered significant rebates for oil-to-heat-pump conversions. Check current offerings before committing — rebates have ranged from $500 to $5,000+ depending on the program year and system type. An EnerGuide home energy assessment may be required to qualify.
The Smart Conversion Path
This phased approach spreads costs over 1–2 years and lets you verify heat pump performance through a full NB winter before committing to full oil removal.
