Cutting the number down

Heating one occupied room and letting the rest of the house sit cooler is the whole case for a space heater. Running one in every room costs more than central heat.
Ceramic, oil-filled and infrared heaters all convert essentially 100% of the electricity to heat. At the same wattage the running cost is identical, whatever the box claims.
The cheapest watt is the one you skip: closing the door to the room you are heating does more than any model upgrade.
