Boiler Energy Bill Calculator — Estimate Your Winter Heating Cost
Published: July 23, 2026 — CANRO Heating & Cooling — Greater Vancouver, BC
Quick Estimate
Average Vancouver home with a 85% AFUE boiler: $100-200/month in winter. With a 95% condensing boiler: $90-180/month. Annual heating cost for a typical home: $800-1,600. These estimates assume a 2,000 sq ft home with average insulation and thermostat set to 21°C during the day, 18°C at night.
Factors That Lower Costs
New condensing boiler (90%+): saves 10-15% vs standard 85% boiler. Weather compensation: saves 5-15%. Smart thermostat: saves 10-15%. Programmable thermostat: saves 8-12%. Lower thermostat 1°C: saves 2-3%. Add insulation: saves 10-30%. These improvements can combine to reduce your bill by 30-50%.
Tracking Your Usage
Track your FortisBC bill monthly. Compare the GJ used in the same month year-over-year. If your usage increases by more than 10% without a colder weather explanation, your boiler efficiency may be declining. Schedule annual service to restore efficiency. A boiler that needs cleaning or adjustment can waste 10-20% of the gas it consumes.
