About oil-filled radiator running costs
Oil-filled radiators heat slowly and keep warming the room after the element switches off, so they cycle less than fan heaters.
Typical sizes: 700 W, 1,000 W, 1,200 W, 1,500 W.
How to spend less: Choose a model with a thermostat and place it away from curtains and drafts.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average in Pennsylvania. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
