An electric space heater can reduce your utility bills, but only if you lower the thermostat on your central heating system. Homes typically have central heating systems with a capacity of 50,000 to 100,000 Btuh, so obviously a single space heater can't heat an entire house.

Consequently, can a space heater heat a room?

Space heaters heat only the area where they're placed. You put one in the room you're currently using and it heats that room, usually through convection (or circulation–the same way HVAC heats). You could even use a radiant heater to heat only the area directly in front of the heater.

Secondly, is it cheaper to run the heat or a space heater? The Energy Department estimates that the cost to heat an entire home with electric space heaters cost 43% more than a gas furnace. Using a space heater in your bedroom only while you sleep is a practical way to use a space heater and won't make much of a dent in your electricity bill.
