A small apartment is easy to heat if you pick the right kind of heater for the room. Ceramic heaters warm a space fast, oil-filled radiators are quiet for sleeping, and a tiny desk heater can keep you comfortable without heating the whole place.

Before you buy: 60-second checklist
- Match the heater to the room: a 1500W heater is usually enough for one small room; a 500W heater warms a person, not the room.
- Look for tip-over protection, overheat protection and a thermostat on any heater you buy.
- Plug heaters directly into a wall outlet, never into an extension cord or power strip.
- Keep 3 feet clear around the heater: no curtains, bedding, clothes or furniture.
- Check your lease: some buildings limit portable heaters, and older wiring may not handle two at once.
The picks in detail
Dreo Atom One Space Heater
Best for: Most small bedrooms and studios
A compact 1500W ceramic heater with a digital thermostat, oscillation, a timer and a remote, so you can set a temperature instead of cycling it on and off.
📏 Before you buy: Plug it straight into a wall outlet, keep 3 feet clear around it and use the thermostat rather than running it on high all night.

Best for: Quiet heat in a bedroom
An oil-filled radiator has no fan, so it is close to silent and keeps radiating heat after the thermostat clicks off. It has a programmable timer.
📏 Before you buy: It is heavier and wider than a ceramic heater and warms up slowly. Measure the floor space next to the bed first.
Check price on Amazon →Vornado MVH Space Heater
Best for: Evening out a cold, drafty room
Instead of blasting one spot, it circulates warm air around the whole room, which suits an open studio where the bed and sofa share one space.
📏 Before you buy: It is a fan heater, so you will hear it. Check your outlet: like most heaters it draws up to 1500W.
Check price on Amazon →Lasko 754200 Ceramic Heater (9 in)
Best for: A simple, low-cost heater for one room
A small, no-frills ceramic heater with an adjustable thermostat and a carry handle. Easy to move from the bedroom to the bathroom doorway.
📏 Before you buy: It has manual controls only, no timer or remote. Never leave it running in an empty apartment.
Check price on Amazon →Lasko 751320 Ceramic Tower Heater
Best for: Tight corners and narrow spaces
A 23-inch tower with a small footprint, oscillation, a thermostat and a remote. It fits in a gap beside the sofa where a wide heater would not.
📏 Before you buy: Tall heaters tip more easily; it has tip-over protection, but put it where nobody will knock it, away from curtains.
Check price on Amazon →Amazon Basics 500W Mini Ceramic Heater
Best for: Cold feet under a desk
A tiny 500W personal heater with tip-over protection. It warms you, not the room, which is all you need at a desk and it uses about a third of the power.
📏 Before you buy: It will not heat a whole room. Keep it off rugs that block the air intake and away from paper and bags.

We shortlist products that solve a specific small-space problem, are widely available in the US, and work without drilling where possible. We look at dimensions, materials and what buyers commonly report, and we say clearly when a product may not suit a space. We do not claim hands-on testing unless we did it.
Questions people ask
What size space heater do I need for a small bedroom?
For a typical small bedroom, a 1500W heater with a thermostat is plenty. Use the thermostat or the low setting once the room is warm instead of running it on high.
Is it safe to leave a space heater on overnight?
Manufacturers and fire-safety agencies advise against leaving a heater running unattended or while you sleep. If you want warmth at night, a quiet oil-filled radiator with a timer is the better choice, kept well away from bedding.
Can I plug a space heater into an extension cord?
No. Space heaters draw a lot of power and should go straight into a wall outlet. Avoid running two heaters on the same circuit in an older apartment.
Which is quieter, a ceramic heater or an oil-filled radiator?
An oil-filled radiator, because it has no fan. Ceramic and vortex heaters use a fan to move warm air, so they heat faster but make some noise.
Is the Dreo Atom One part of the 2026 Dreo space heater recall?
No. The recall announced by the U.S. CPSC on October 29, 2026 covers the DREO DR-HSH015 ceramic heater made from April 2025 to January 2026 (sold at Costco and other stores). The Atom One is a different model (DR-HSH004). If you own any space heater, check the model number on its label against the recall list at cpsc.gov before using it.
