Space Heater vs Central Heating: Which Costs Less?
Which heating method costs less?
Quick Answer
For heating one or two rooms, a space heater is almost always cheaper than running central heating for the whole house. A single 1,500W space heater costs about $32.40/month at 4 hours daily, while the average gas furnace runs $80–$120/month in winter. The break-even point is typically 3 rooms.
