A cheaper way to do the same job
- A ductless heat pump giving the same heat would cost $17.18 a month in season, saving $34.36 a month in season and $170.57 a year. Assumes a heat pump coefficient of performance (COP) of 3.
- An electric blanket for the same hours would cost $3.44 a month in season, saving $48.10 a month in season and $238.80 a year.
Ways to spend less
- Heat the person, not the room: a space heater makes sense only when it lets you turn the central thermostat down for the rest of the house.
- Run it an hour less each day. Saves about $6.44 a month in season.
- Use the low setting when the room is already warm; many 1,500 W heaters drop to about half power on low. Saves about $25.77 a month in season.
- Close the door of the room you are heating so the warm air stays where you are.
- Use a timer or thermostat plug so it doesn't run after you leave the room.
