Getting started

Getting started

The best space heaters can quickly heat you and an average sized room for as little as $40. Electric heaters such as those we test include an array of safety features that reduce the risk of fire. But that doesn't mean all of them are risk-free. Many we tested got hot enough to cause the equivalent of a bad sunburn within a second of contact.

All of the space heaters in Consumer Reports tests will comfortably warm a chilly room. But remember, the only way to potentially save money is to use a heater in one room and leave the rest of the house chillier.

When you shop for an electric space heater, look for a label from a recognized testing laboratory such as UL (Underwriters Laboratory), ETL (Intertek), or CSA (Canadian Standards Association) verifying that the heater's construction and performance meet voluntary U.S. safety standards.

Also, fuel-burning space heaters are more dangerous than electrics. We suggest that you consider them only for emergency use, say, during a winter power outage.

Our experts and the National Fire Protection Association offer the following safety advice:

  • Don't leave an electric heater unattended while it's plugged in. Place the heater on a level, flat surface where children and pets can't reach it and never in a child's room. Use a heater on a tabletop only when specified by the manufacturer. If you place it on furniture, it could fall and be damaged.
  • Don't use a space heater in a damp or wet area unless it's designed for outdoor use or in bathrooms. Moisture could damage it.
  • Keep combustible materials such as furniture, bedding, and curtains at least three feet from the front of the heater and away from its sides and rear. Don't use a heater near paint, gas cans, or matches. Keep the air intake and outlet clear.
  • Run the electric cord on top of area rugs or carpeting so that you can step over it and not abrade it underfoot. Plugging another electrical device into the same outlet or extension cord as the heater could cause overheating.

How to choose

We think all manufacturers should keep hot surfaces completely out of reach. Models that scored very good or higher in our hot-surface tests make even minor burns unlikely, if not impossible. Here's what else to consider while shopping.

Choose the right type. Look for fast spot heating if you care more about quickly heating one or two people than heating a roomful of guests. Consider larger heaters if you like the look of wood and an electronic flame display. And consider propane or kerosene heaters strictly for screened-in porches and other well-vented outdoor areas. Both types pose a carbon monoxide hazard indoors and typically get hot enough to ignite fabrics.

Look for safety features. All of the heaters we tested include a sensor that shuts them off if they overheat. A switch that does the same if they tip over is a welcome plus for taller models, especially with kids and pets nearby. Instructions for all the models we tested also warn consumers to keep them away from water. One model has a plug that's ground-fault protected, though kitchens, bathrooms, and other moist areas should already have protected outlets.

Insist on a fan. It helps distribute heat more quickly, and it shows: The three slowest heaters in our tests are the only ones without fans. Some models can oscillate for more even heating. Don't expect savings. More than 60 percent of homeowners we polled recently thought that space heaters could trim their energy bills. Yet the only way you can save is if you lower heat in other rooms, since electricity is the most expensive way to heat. So consider a space heater strictly for comfort. And think about adding insulation to attics, basements, crawl spaces, and other key areas for savings.

Types

Space heaters that burn fuel are dangerous, and even electric space heaters pose significant risks of fire and electrical shocks if you don't use them safely. Here are the types of space heaters to consider.

Electric heaters


Convection models are best for heating an entire room because they spread their heat over a wide area. Those with a fan spread warmed air quicker, but they also add noise. Radiant versions, which use an electric-ribbon element or a quartz tube, are ideal for spot heating, but their heat dissipates quickly when they're turned off.

Propane and kerosene heaters


These produce prodigious heat. But because of their open flame, the risk of carbon monoxide poisoning, and the hazards associated with handling the fuel, we recommend against their use indoors except during emergencies, and then only in areas with good ventilation.

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.
