Best Space Heater for a Bedroom
This page contains affiliate links. As an Amazon Associate I earn from qualifying purchases. Product details come from each listing and maker; we have not tested these heaters ourselves.
In a bedroom, the things that matter are noise, a thermostat that holds a steady temperature, and an auto-off timer. These picks are either fanless or have quiet fans, and each one has tip-over and overheat protection. A typical bedroom of 100–150 sq ft is well within what one 1,500 W heater can handle.

Using a heater in a bedroom
- Set the timer to warm the room before bed, or to shut off an hour or two after you fall asleep. Safety groups advise not running a heater overnight while you sleep.
- Keep it 3 feet from the bed, curtains and laundry.
- Around 65–68°F is a comfortable sleeping temperature for most people, and costs less to hold than 72°F.
Space heater safety basics
- Plug the heater straight into a wall outlet. Heater makers and the U.S. Consumer Product Safety Commission both warn against extension cords and power strips.
- A 1,500 W heater draws about 12.5 amps. Don't run two on the same circuit, or with a microwave or hair dryer on that circuit.
- Keep 3 feet of clear space around it: beds, curtains, paper and clothes.
- Look for tip-over and overheat protection and a safety certification mark (UL, ETL or CSA).
- Turn it off when you leave the room. Safety groups also advise turning heaters off when you go to sleep, so a timer or auto-off setting is useful in a bedroom.
- 240 V garage heaters are hardwired. Have an electrician run the circuit and follow the wire and breaker sizes in the manual.
