Space Heater Smarts: Safety Habits to Share Before the First Cold Night

Every October, a familiar ritual plays out in apartments and triple-deckers across New England. The first chilly evening arrives, the building heat has not kicked on yet or the radiators are still clanking to life, and someone pulls a space heater out of the back of a closet. Space heaters can be a real comfort, especially for older neighbors who feel the cold more and for people in drafty rooms. They also deserve respect, because heating equipment is one of the leading causes of home fires in the United States.

This guide covers the habits that make space heaters safer, and simple ways to help a neighbor who relies on one.

Start With an End-of-Storage Check

Before plugging in a heater that has spent months in a basement or closet, take a few minutes to look it over.

• Cord and plug: Look for fraying, cracks, scorch marks or a plug that feels loose in the outlet. Any of these is a reason to retire the heater.
• Housing: Check for cracks, missing grilles or broken knobs.
• Dust and debris: Unplug the unit and gently remove dust from the grille. Dust burning off can create smells and, in worse cases, a hazard.
• Safety features: Many newer heaters have automatic shut-off if they tip over or overheat. If an older model lacks these, it may be time to replace it.
• Certification label: Look for a mark from a recognized independent testing laboratory on the heater or its tag.

The Three-Foot Rule

The single most important habit with any space heater is giving it room. Keep anything that can burn at least three feet away. That includes:

• Curtains, bedding and blankets
• Sofas, armchairs and cushions
• Clothes drying on racks
• Paper, mail, books and magazines
• Pet beds and children’s toys

A simple way to remember it: if you can reach out from the heater and touch it, it is too close. Some households mark a “heater zone” on the floor with a rug edge or a piece of painter’s tape so everyone, including kids, can see where the boundary is.

Plug It Into the Wall, Not a Power Strip

Space heaters draw a lot of electricity. Most manufacturers say to plug them directly into a wall outlet, not into an extension cord or power strip, which can overheat. A few related tips:

• Do not run the heater’s cord under rugs or furniture, where damage can go unnoticed.
• Avoid plugging other high-draw appliances into the same outlet at the same time.
• If the plug or outlet feels hot to the touch, turn the heater off and have the wiring checked.

Turn It Off When You Leave or Sleep

Space heaters are meant to be used while someone is awake and in the room. Make it a household rule to turn the heater off and unplug it when:

• Everyone leaves the room
• Everyone goes to bed
• You leave the house, even for a short errand

If a bedroom is too cold to sleep in without a heater, that is worth raising with a landlord, building manager or local housing office, since landlords in Massachusetts are generally responsible for providing adequate heat during the heating season.

Fuel-Burning Heaters Need Extra Care

Some people use kerosene or other fuel-burning portable heaters, especially in garages or older homes. These carry an added risk of carbon monoxide, an invisible gas that can make people very sick. If anyone uses a fuel-burning heater:

• Follow the manufacturer’s instructions on ventilation and fuel exactly.
• Never use outdoor equipment, such as grills or camp stoves, to heat indoor spaces.
• Make sure working carbon monoxide alarms are installed on every level of the home and outside sleeping areas.
• Check local rules, since some fuel-burning heaters are restricted in certain types of housing.

Helping a Neighbor Who Uses a Space Heater

Older adults, people with limited mobility and people on tight budgets often rely on space heaters to stay comfortable. A friendly visit can make a big difference. Here is a respectful way to approach it.

1. Start with conversation, not inspection. Something like: “It got cold fast this week. Is your place staying warm enough?”
2. Offer specific help. “Would it help if I moved that chair back a bit so there’s more room around the heater?” is easier to say yes to than a general offer.
3. Check the basics together. Look at the cord, the outlet and the space around the heater. Make sure there are working smoke and carbon monoxide alarms nearby.
4. Solve the clutter problem gently. If papers or blankets tend to pile up near the heater, suggest a basket or shelf somewhere else for them.
5. Know when to escalate. If the heater is clearly damaged, the outlet is scorched, or the person is heating the whole apartment with an oven or stove, it may be time to involve family, the landlord or a local elder services agency.

Warmth Beyond the Heater

Sometimes the safest move is to need the heater a little less. Simple steps can help a room hold warmth:

• Close curtains at night and open them on sunny days.
• Use draft stoppers at the bottom of doors.
• Layer clothing, slippers and a warm hat indoors.
• Keep interior doors closed to hold heat in the rooms being used.

And if a neighbor is struggling to afford heat at all, help them connect with heating assistance programs through Mass 211 or a local community action agency.
