Question 1

Are infrared heaters cheaper to run?

Accepted Answer

No. At the same wattage, all electric heaters cost $0.27/hour. Only lower wattage reduces cost.

Question 2

What’s the cheapest type of heater?

Accepted Answer

Electric blanket at 200W — $8.64/month at 8 hours daily. Among room heaters, a 600W panel at $19.44/month. All 1,500W types cost $48.60/month.

Question 3

Do oil-filled radiators save money?

Accepted Answer

Not per hour — both draw 1,500W. But with a thermostat, the oil retains heat and may reduce effective runtime 10–20%.

Is upgrading my heater worth it?

Accepted Answer

Only if changing wattage. 1,500W ceramic → 1,500W oil saves nothing. But 1,500W → 200W electric blanket saves ~$$56.16/month overnight.
