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.

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.
