What's cheaper to use, run 2 1500 watt radiator oil heaters or crank up the gas heat?
I've got a 12 x 22 room that has one wall vent and no cold air return. I've placed one to two oil-filled 1500 watt "space heaters" in this space to keep the temp up. In louisville KY, whats cheaper to operate, gas furnace or electric wattage?
It depends on what the rates are in your area.
If you have natural gas it should be cheaper than electric but if your propane gas it would be a little more expensive than electric.
