Space Heater Buying Guide

Sales of space heaters are sizzling as millions of homeowners buy into the promise of lower-cost heating in an era of soaring utility bills. But there are also important safety issues to consider, especially if you have small children or pets in your home. Newer models tend to be safer.

Features

Safety is vital when using a space heater. Look for features that make the units easier and safer to use. Here are the important safety-related space-heater features to consider.

Handle

If you'll be moving the heater from room to room, look for a lightweight model with a handle that provides a safe grip. Most electric models are lighter than fuel-operated ones.
 

Oxygen Depletion Sensor or Low-Oxygen Shutoff

For fuel-fired models, this feature shuts off the heater's fuel flow when it senses a reduction in the amount of oxygen in the air due to the buildup of carbon dioxide.
 

Power cord

Those on the electric models we tested were at least 70 inches long, providing more placement options. If you have to use an extension cord, choose a 12- or 14-gauge model. Overloaded, undersized, or frayed power cords are a major cause of fires, injuries, and deaths associated with space heaters. Inspect electric-space-heater cords for damage regularly.
 

Thermostat

A thermostat maintains the temperature you set, saving you the hassle of turning the heater off and on as the room temperature varies. Heaters with multiple output settings conserve energy by letting you choose the lowest setting that keeps a room comfortable.
 

Tip-over switch, touch sensor, overheat protection

As their names imply, these features automatically turn off the heater if it's knocked over, if the grille is touched, or if the unit overheats.
