Space Heaters
Almost every plug-in heater sold in the US tops out at 1,500 watts, the most a standard household circuit comfortably supplies. The differences are in how a heater spreads that warmth: a fan-forced or vortex heater warms a whole room, a personal heater warms the person in front of it, and a thermostat keeps either from running flat out all night.
Whatever you choose, look for tip-over and overheat protection.
