How much does it cost to run electric baseboard heaters per month in New Brunswick?

Electric baseboard heating costs in New Brunswick are directly tied to NB Power's electricity rates, your home's insulation, the size of your living space, and how cold the Maritime winter gets. Here's a realistic breakdown of what you can expect.

NB Power Electricity Rates

As of the latest rate schedule, NB Power charges approximately $0.1131 per kWh for residential customers (the first block of energy usage). There's a second block rate that kicks in at higher consumption levels at roughly $0.1474 per kWh. Homes heated with electric baseboard almost always hit the second block during winter months, so budgeting at the higher rate is more realistic for heating cost calculations.

NB Power also charges a daily service charge (around $0.70/day or roughly $21/month) regardless of consumption, plus HST at 15% — New Brunswick's combined provincial and federal sales tax.

Monthly Cost Estimates by Home Size

These estimates assume average insulation, thermostat set to 20°C (68°F), and typical Maritime winter temperatures:

| Home Size | Heating Load | Monthly Cost (Dec–Feb) | Monthly Cost (Oct/Nov, Mar/Apr) |
|-----------|-------------|----------------------|-------------------------------|
| Apartment/Condo (700 sq ft) | 4,000–5,000W | $250–$350 | $120–$180 |
| Small house (1,000 sq ft) | 6,000–8,000W | $350–$500 | $170–$250 |
| Medium house (1,500 sq ft) | 9,000–12,000W | $450–$650 | $220–$350 |
| Large house (2,000+ sq ft) | 12,000–16,000W | $600–$900 | $300–$450 |

These are heating costs only — add your base electrical usage (lights, appliances, hot water if electric) of roughly $80–$150/month on top.

How the Calculation Works

A 1,500-watt baseboard heater running continuously for one hour uses 1.5 kWh. In the coldest months (January and February), a heater in an average-insulated room might run 60–80% of the time — roughly 14–19 hours per day.

Example calculation for one 1,500W heater:

• 1.5 kW × 16 hours/day × 31 days = 744 kWh/month


• 744 kWh × $0.1474/kWh = $109.67/month (plus HST)


• With 15% HST: $126.12/month for ONE heater

A medium-sized home with 6–8 baseboard heaters can easily accumulate 3,000–5,000 kWh/month in heating electricity alone during peak winter.

Why New Brunswick Costs Are Higher Than Average

Several factors make electric baseboard heating particularly expensive in New Brunswick:

Climate: The Maritime climate means a long heating season — typically October through April (7 months). While our winters aren't as cold as Northern Ontario or the Prairies on average, the combination of damp ocean air and persistent wind chill means heaters work harder than raw temperature readings suggest. Moncton averages about 4,600 heating degree days annually, Saint John about 4,500, and Fredericton about 4,800 (being inland and slightly colder).

Older housing stock: Many homes in Saint John, Fredericton's older neighbourhoods, Bathurst, and smaller communities were built in the 1960s–1980s with insulation standards well below today's requirements. Poor insulation means heat escapes faster, and baseboard heaters run longer to compensate. Upgrading attic insulation from R-20 to R-60 (current NB building code minimum) can reduce heating costs by 15–25%.

Electricity rates: NB Power's residential rates are mid-range for Canadian provinces but significantly more expensive than heating with natural gas (which isn't widely available in many New Brunswick communities). Only parts of the Saint John to Moncton corridor and some Fredericton areas have natural gas service through Liberty Utilities.

Ways to Reduce Your Baseboard Heating Costs

Heat pumps: A ductless mini-split heat pump is the single most effective upgrade for New Brunswick homes with baseboard heat. Modern cold-climate heat pumps (like Mitsubishi Hyper-Heat or Fujitsu XLTH) operate efficiently down to -25°C to -30°C and can reduce heating costs by 40–60%. NB Power and the federal government offer rebates that can cover $2,000–$5,000 of the installation cost. A typical single-zone installation runs $3,500–$5,500 before rebates.

Programmable/smart thermostats: Replacing manual baseboard thermostats with programmable or smart line-voltage thermostats (Mysa or Sinopé — both Canadian brands designed for baseboard heat) lets you set schedules to lower temperatures when sleeping or away. Savings: 10–15% on heating costs.

Insulation upgrades: Adding blown-in cellulose to attic and wall cavities is one of the highest-ROI improvements. Cost: $1,500–$4,000 for a typical home. NB Power's Total Home Energy Savings Program may offer rebates.

Window upgrades: Replacing single-pane windows with double or triple-pane Energy Star certified units reduces heat loss dramatically. Especially impactful in older homes in Campbellton, Edmundston, and other northern New Brunswick communities where winter temperatures regularly drop below -20°C.

Zone heating: Use thermostats to lower temperatures in unused rooms. Closing a bedroom to 15°C (59°F) during the day while keeping living areas at 20°C can save $30–$60/month across the heating season.

Realistic Annual Heating Cost

For a 1,500 sq ft home with electric baseboard heat, average insulation, and thermostats set to 20°C, expect total annual heating electricity costs of approximately $2,500–$4,000 — spread across the October-to-April heating season. This makes electric baseboard one of the most expensive heating methods available, which is why NB Power actively encourages heat pump adoption as a supplemental or primary heat source.
