Why this is a major load on your bill
Because the Electric Furnace runs continuously (three or more hours at a time) at 15,000 watts, it contributes meaningfully to total household consumption. A typical US home uses about 10,800 kWh per year (EIA RECS), so this single appliance accounts for roughly 125.0 percent of total household electricity use. Worth focusing on for efficiency upgrades.

Electric Furnace Energy Usage Explained
A electric furnace consumes 15000W. At 6 hours/day for 150 days/year, that is 13,500 kWh annually, about 128.6% of average US household usage (10,500 kWh).
How to Calculate Running Cost
Cost = (Watts ÷ 1000) × Hours × Rate
For your electric furnace: (15000W ÷ 1000) × 6 hrs × $0.16/kWh = $14.40/day.
Tips to Reduce Costs
Use time-of-use electricity plans for off-peak rates ($0.05–$0.10/kWh overnight). Upgrade to Energy Star certified models. Use smart plugs or timers. Check rates in your state with our Electricity Cost Calculator.
