Best space heaters: safe electric heaters compared (2026)
A space heater warms one room so you can turn the thermostat down elsewhere, or take the chill off a cold bedroom. CPSC estimates that portable heaters, including electric space heaters, are involved in an average of 1,600 fires a year, so the features matter more than the looks. This page compares six 1500-watt heaters sold by Amazon on the safety features their listings name: tip-over and overheat shut-off, and an ETL or UL listing. We haven't tested them ourselves.

Our verdictOur verdictResearched One of Amazon's best-known space heaters: a 23-inch oscillating ceramic tower with overheat protection, a cool-touch case and an ETL listing, run from a remote with a 7-hour timer.

Our verdictOur verdictResearched Lasko's digital tower adds an adjustable thermostat, so it cycles to hold the room at the temperature you set rather than running flat out. It oscillates, has two heat settings, a timer and a remote, and overheat protection. Like the 751320, the listing doesn't mention a tip-over switch.

Ceramic, non-oscillating · 1,500 W · Thermostat · Tip-over and overheat protection (listing) A basic, low-cost heater with both shut-offs | Ceramic, non-oscillating | 1,500 W | Thermostat | Tip-over and overheat protection (listing) | |
Our verdictOur verdictResearched A simple small ceramic heater with the two safety features that matter most, tip-over and overheat protection, and a thermostat. It doesn't oscillate and the listing names no testing-lab certification, so check the label on the heater itself for UL, ETL or CSA. Best for A basic, low-cost heater with both shut-offs Good

Oil-filled radiator · 1,500 W · Power level, temperature, ComfortTemp · Low surface temperature (listing) Quiet, steady heat for a bedroom | Oil-filled radiator | 1,500 W | Power level, temperature, ComfortTemp | Low surface temperature (listing) | |
Our verdictOur verdictResearched An oil-filled radiator heats slowly and silently, with no fan and no glowing element, and stays warm for a while after it cycles off. De'Longhi's listing stresses a low surface temperature; it doesn't mention tip-over or overheat shut-offs, so check the heater's manual and label. Best for Quiet, steady heat for a bedroom Good

Before you buy
Look for tip-over and overheat shut-off.
CPSC says an automatic cut-off is now required to turn off electric heaters if they tip over; the listings here name it on some models and not others, so we say which.
Check for a testing-lab label.
CPSC advises a seal from a nationally recognized testing laboratory such as UL. ETL (Intertek) and CSA marks are other labs' equivalents; check the label on the heater itself.
Pick the type for the room.
Ceramic fan heaters warm a room quickly; oil-filled radiators are slower and silent, and suit bedrooms and long, steady heating.
Choose a guard and a stable spot.
CPSC advises a heater with a guard around the heating element, placed on a level, hard, nonflammable surface, not on rugs or carpets.
We verify every product's specifications against at least two independent sources, re-check its US price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labeled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test — and commissions never change a ranking either way.

Common questions
What is the safest type of space heater?
Look for features rather than a type: tip-over and overheat shut-off, a testing-lab label such as UL or ETL, and a guard around the heating element. Then use it safely: 3 feet from anything that can burn, plugged straight into a wall outlet, and off when you leave the room.
Can I plug a space heater into an extension cord or power strip?
No. CPSC says to plug electric space heaters directly into a wall outlet and never into an extension cord or power strip, to prevent overloading and causing a fire.
Is it safe to leave a space heater on overnight?
CPSC and the US Fire Administration both say to turn space heaters off when you go to bed. If a room is cold at night, use extra bedding or heated clothing instead.
Will a space heater work in a power outage?
Not unless you have a generator or a large power station, and at 1500 watts it would drain a power station quickly. For outages, see our guide to staying warm without power.
Oil-filled radiator or ceramic heater?
A ceramic heater blows warm air and heats a room quickly; an oil-filled radiator heats slowly and silently and keeps radiating for a while after it cycles off. Both on this page draw up to 1500 watts.
