Turning up the central heat for the whole house just to warm one room is one of the most expensive habits of winter. A good space heater fixes that: it heats the room you are actually in, often within minutes, and lets you keep the thermostat lower everywhere else.

1. DREO Atom One Space Heater – Best Overall
DREO has become the brand to beat in space heaters, and this compact model is its most popular one, with more than 29,000 ratings and a 4.6-star average. It heats a room quickly at up to 1500W and has a digital thermostat you can set anywhere from 41°F to 95°F.
ECO mode automatically lowers the heat once the room reaches your target temperature, which helps keep the electric bill in check. The 70° oscillation spreads warm air across the room, and the brushless motor keeps it quiet enough for sleeping at around 37.5 dB. Safety is covered too: tip-over and overheat protection, a reinforced plug, and flame-retardant housing.
- Pros: heats fast, precise digital thermostat, ECO mode, quiet, wide oscillation
- Cons: small footprint means it is best for small to medium rooms
- Who it’s for: most people who want one reliable heater for a bedroom, office or den
2. DREO 25-Inch Tower Space Heater – Best for Large Rooms
For a living room or open-plan space, a tower heater moves warm air further, and this 25-inch DREO is one of Amazon’s best sellers with more than 5,000 bought last month. Its longer impeller pushes heat across rooms of roughly 100 to 270 sq ft.
It is impressively quiet, as low as 25 dB, and a dedicated temperature sensor lets the thermostat hold the room steady in ECO mode. You get four heat modes, 70° oscillation, a 45° tip-over switch, overheat protection and a child lock, which matters if you have kids or pets around.
- Pros: covers larger rooms, very quiet, child lock, accurate thermostat, remote control
- Cons: higher price than compact heaters
- Who it’s for: living rooms, basements and families who want one heater for the main room
3. Lasko 751320 Ceramic Tower Heater – Best Classic Tower Heater
The Lasko 751320 has been around for years and still has one of the biggest review counts in the category, more than 40,000 ratings at 4.5 stars. It is a simple, dependable 23-inch tower with 1500W of ceramic heat and wide oscillation for medium-size rooms.
A remote controls the heat settings, oscillation and the 7-hour timer, and the cool-touch housing with automatic overheat protection makes it a safe choice in busy homes. It also has a carry handle so you can move it from the bedroom to the living room.
- Pros: proven track record, remote control, 7-hour timer, cool-touch exterior
- Cons: no tip-over switch listed and no digital ECO mode
- Who it’s for: anyone who wants a trusted, no-fuss tower heater
4. Amazon Basics Ceramic Space Heater – Best Budget Pick
If you just need some extra warmth without spending much, the Amazon Basics heater is hard to beat. It is one of the best-selling space heaters on Amazon, with more than 10,000 bought last month and over 29,000 ratings.
It weighs about 3 lbs and offers High (1500W), Low (900W) and fan-only settings, along with tip-over and overheat protection. It is non-oscillating and fairly basic, but for a dorm room, small bedroom or under a desk it gets the job done for a very low price.
- Pros: very affordable, lightweight, tip-over and overheat protection, fan mode
- Cons: no oscillation or digital thermostat; not for bathrooms
- Who it’s for: students, renters and anyone heating one small space
5. De’Longhi Oil-Filled Radiator Heater – Best Quiet Radiator
Oil-filled radiators work differently from fan heaters. There is no fan, so they are completely silent and do not blow dust, pet dander or pollen around the room. The De’Longhi heats the oil inside its fins, which then releases gentle, steady warmth that lingers even after it cycles off.
Its ComfortTemp feature automatically finds an efficient power level, which De’Longhi says can be up to 20% more efficient. The thermal slot design keeps the surface cooler, and built-in wheels make it easy to roll between rooms. It takes longer to warm up than a ceramic heater, but it is ideal for bedrooms and all-night use.
- Pros: silent, no blowing air, steady heat, energy-saving mode, rolls on wheels
- Cons: slower to heat up, heavier and pricier
- Who it’s for: light sleepers, allergy sufferers and anyone heating a bedroom overnight
6. Lasko CD08200 Bathroom Heater – Best for Bathrooms
Most space heaters should never be used in a bathroom. This small Lasko is the exception: it comes with an ALCI safety plug that cuts the power if it detects a fault, and Lasko approves it for bathroom use.
It packs 1500W into an 8-inch body, with two heat settings and a one-hour timer so the bathroom is warm when you step out of the shower. Overheat protection and a cool-touch housing round out the safety features.
- Pros: approved for bathroom use with ALCI plug, compact, timer, cool-touch
- Cons: basic controls with no thermostat display
- Who it’s for: cold bathrooms and anyone who hates stepping out of a warm shower
7. Amazon Basics 500W Mini Desk Heater – Best Personal Desk Heater
For cold feet under the desk or a chilly office cubicle, a full 1500W heater is overkill. This tiny Amazon Basics heater is about 6 inches tall, weighs 1.4 lbs and runs at just 500W, so it is gentle on the circuit and the power bill.
It warms you up within seconds, has tip-over protection, and is small enough to sit on a desk, shelf or the floor right next to you.
- Pros: tiny, low power draw, fast personal warmth, very cheap
- Cons: only warms the person in front of it, not the whole room
- Who it’s for: home offices, cubicles and anyone who just wants warm hands and feet
Space Heater Safety Tips
- Plug the heater directly into a wall outlet. Never use an extension cord or power strip with a 1500W heater.
- Keep at least 3 feet of clear space around it, away from curtains, bedding, furniture and paper.
- Choose a model with tip-over and overheat protection, and look for an ETL or UL safety listing.
- Only use a heater in a bathroom if the manufacturer approves it, like the Lasko CD08200 with its ALCI plug.
- Turn it off when you leave the room or go to sleep, unless it is designed for unattended use, and keep it away from kids and pets.
How to Choose a Space Heater
Ceramic, tower or oil-filled?
Ceramic heaters with a fan heat up fastest and are the most affordable. Tower heaters are ceramic heaters in a taller body that spreads heat further across bigger rooms. Oil-filled radiators are slow to warm up but completely silent and hold heat well, which makes them great for bedrooms and all-night use.
Match the heater to the room size
Most plug-in heaters top out at 1500W, which is enough for a room of roughly 150 sq ft as a main heat source, or a larger room as a supplement to central heating. For a bigger living room, choose a tower model with oscillation. For a desk, a 500W personal heater is plenty.
Look for a thermostat and ECO mode
A digital thermostat lets the heater switch itself down once the room is warm, instead of running at full power all the time. That saves energy and keeps the room from getting stuffy.
Frequently Asked Questions
What is the most energy-efficient space heater?
All 1500W electric heaters turn electricity into heat at about the same rate. The savings come from running less, so look for a good thermostat and ECO mode, like the DREO models, and only heat the room you are using.
Is it safe to leave a space heater on overnight?
It is safest to turn it off when you sleep. If you do run one overnight, choose a model with tip-over and overheat protection and a thermostat, keep 3 feet of clearance, and plug it straight into the wall. Oil-filled radiators like the De’Longhi are a popular choice for bedrooms because they have no exposed heating element or fan.
What size space heater do I need?
A common rule of thumb is about 10 watts per square foot, so a standard 1500W heater suits a room of around 150 sq ft as the main heat source. If the heater is only topping up your central heating, it can handle a larger space.
Can I plug a space heater into a power strip?
No. Space heaters draw a lot of current and can overheat power strips and extension cords. Always plug them directly into a wall outlet.
Final Verdict
For most homes, the DREO Atom One is the best space heater to buy: fast, quiet, and smart about saving energy. Heating a big living room? Go for the DREO 25-inch tower. On a tight budget, the Amazon Basics ceramic heater is a proven best seller, and if you want silent warmth for the bedroom, the De’Longhi oil-filled radiator is worth the extra cost.
