The best space heater for home office use is a 1500-watt ceramic model that runs under 40 decibels, and the DREO Atom One fits that description at desk size. Your hands go stiff by mid-morning. The room never quite warms up. And last winter’s heater drones so loudly that you mute yourself on every call.
That’s the real problem. A home office heater has to be quiet, small, and safe to leave on while you work. Raw heat is the easy part. Plug-in heaters all top out at 1500 watts, so the real differences are noise, footprint, controls, and safety shutoffs.
This list sorts nine heaters on exactly those points. Every pick is sold on amazon.com, and every spec comes from the manufacturer’s own page or listing. The range runs from a desk-corner personal heater to a fanless oil-filled radiator that makes no blower noise at all.

The 9 Best Space Heaters for a Home Office
1. DREO Atom One (DR-HSH004) – Best Overall
| Feature | Specification Details |
|---|---|
| Physical Dimensions | 6.7 x 5.5 x 10.3 inches (W x D x H), 3.8 lb |
| Warranty Length | 12 months from the day you buy it |
| Box Contents | Heater and user manual; the remote runs on a CR2025 coin cell |
| Noise Level | 37.5 dB |
The DREO Atom One is a desktop-size ceramic heater that warms you and your desk corner fast. It runs at 1500 watts on high and 1000 watts on low, with a programmable thermostat from 41 to 95°F. A 70-degree oscillation spreads the warmth across your chair and desk instead of blasting one spot.
Dreo’s own page rates it at 37.5 decibels. That’s quiet for a fan heater, but it isn’t silent. A 1-to-12-hour timer and a remote suit a workday, and a washable filter catches dust. You’ll need to clean that filter.
The footprint is the real draw. At 6.7 by 5.5 inches, it fits on a credenza or on the floor beside a desk leg. Measure your desk first, and our guide to the best home office desks lists the depth of 20 popular models.
The tradeoff is room size. This is a small-office heater, and a large or drafty room needs the tower below. Dreo’s page also names no safety certification, though Amazon’s listing says the protections are ETL-listed. Look for the mark on the box.
Buy This If: Your office is a spare room or a converted closet and you want a quiet, desk-size heater. Skip This If: You’re heating a large or drafty room.
2. DREO Solaris Max 25-Inch (DR-HSH013) – Best Quiet Tower
| Feature | Specification Details |
|---|---|
| Physical Dimensions | 8.66 x 8.66 x 26.77 inches (W x D x H), 8.83 lb |
| Warranty Length | 12 months from the day you buy it (Dreo’s standard policy) |
| Box Contents | Heater, remote with battery included, quick start guide, user manual |
| Noise Level | 32 dB on Dreo’s spec page; the Amazon listing says as low as 25 dB |
The DREO Solaris Max 25-inch is the quiet tower for a bigger home office. Dreo’s spec page lists 32 decibels, and the Amazon listing says as low as 25. That gap is worth knowing about. Both numbers are low for a fan heater.
It heats at 1000 to 1500 watts, oscillates 70 degrees, and moves air at 11.5 feet per second. A 1-to-12-hour timer and a remote come in the box, with the battery included.
The tower stands 26.8 inches tall on an 8.7-inch base. It sits on the floor and tips more easily than a desktop unit, so give it a clear spot away from your chair wheels. The warranty is 12 months, shorter than Lasko’s three years on its towers below.
Pick this one when noise on video calls matters more than saving floor space.
Buy This If: You’re on calls all day in a room larger than a closet and want a tower that stays quiet. Skip This If: You need a heater that fits on a desk or want a warranty longer than 12 months.
3. Lasko 755320 – Best Digital Tower
| Feature | Specification Details |
|---|---|
| Physical Dimensions | 7.0 x 7.25 x 23.0 inches (W x D x H), 7.29 lb |
| Warranty Length | 3 years |
| Box Contents | Tower heater, remote control, user manual; remote batteries not included |
| Noise Level | Not published by manufacturer |
The Lasko 755320 is a digital ceramic tower with a three-year warranty and an ETL listing. Heat runs from 900 to 1500 watts across two settings. Lasko rates it for about 150 square feet, which covers most spare bedrooms.
You get oscillation, an 8-hour timer, a digital thermostat, and a remote. The housing stays cool to the touch, and overheat protection is built in.
Lasko doesn’t publish a noise figure for this model, so you can’t compare it to the Dreo numbers. It also has only two heat settings, and the remote needs batteries you supply. The timer tops out at 8 hours, while the Dreo models go to 12.
It’s a solid, plain heater. The warranty is the reason to choose it over the cheaper Dreo.
Buy This If: You want a long warranty and an ETL-listed tower for a spare-bedroom office. Skip This If: Published noise numbers matter to you, since Lasko lists none for this model.
4. Lasko Ellipse CT24950 – Best Auto-ECO Mode
| Feature | Specification Details |
|---|---|
| Physical Dimensions | 9.12 x 9.12 x 24.1 inches (W x D x H), 5 lb |
| Warranty Length | 3-year limited warranty |
| Box Contents | Not published by manufacturer; ships fully assembled |
| Noise Level | Under 40 dB |
The Lasko Ellipse CT24950 is the tower with an AutoECO mode. Lasko says AutoECO adjusts heater output to hold your set temperature and can use 50 percent less energy. That’s Lasko’s claim, not an independent test.
You get three heat settings and two fan settings, plus a 120-degree oscillation sweep. A 12-hour timer runs in 30-minute steps for the first two hours, then hourly. Lasko lists operation at under 40 decibels and a 3-year limited warranty.
It’s lighter than the Dreo tower at 5 pounds. But the 9.1-inch square base is wider, so it eats more floor. Lasko’s page doesn’t itemize what’s in the box or name a certification, which makes the listing less complete than the 755320’s.
The tradeoff is simple. You get smarter temperature control, and you give up some floor space and spec detail.
Buy This If: You leave the heater running all day and want it to ease off by itself. Skip This If: You’re short on floor space or want a published certification and box list.
5. Dr Infrared DR-968 – Best Infrared
| Feature | Specification Details |
|---|---|
| Physical Dimensions | 11 x 13 x 16 inches (W x D x H), 19 lb |
| Warranty Length | Not published on the product listing; terms sit in a PDF linked from it |
| Box Contents | Heater, remote control, owner’s manual, AAA batteries |
| Noise Level | 39 dB |
The Dr Infrared DR-968 is the infrared pick, built for people who want radiant warmth plus a blower. It pairs an infrared quartz tube with a PTC ceramic element. The listing rates it around 5200 BTU at 1500 watts and 12.5 amps.
The blower is listed at 39 decibels. The thermostat runs from 50 to 85°F, and a 12-hour timer, remote, caster wheels, and a lifetime filter come with it, per the listing.
At 19 pounds, this is a floor heater, not a desk heater. The caster wheels make it easy to roll to your feet and back. The paperwork is thin too. The warranty terms aren’t on the product page, so read that PDF before you buy.
Choose it when you want infrared warmth on your legs and have the floor space for a cabinet.
Buy This If: You want infrared warmth aimed at you and can spare a 13-by-11-inch patch of floor. Skip This If: You need a desk-size unit or a clearly stated warranty up front.
6. Vornado AVH10 – Best Auto-Climate
| Feature | Specification Details |
|---|---|
| Physical Dimensions | 9.25 x 11.63 x 12 inches (W x D x H), 5.4 lb (Amazon listing) |
| Warranty Length | 5-year satisfaction guarantee (Vornado’s wording, not a standard warranty) |
| Box Contents | Heater only |
| Noise Level | Not published by manufacturer |
The Vornado AVH10 is the heater that adjusts itself. Auto Climate senses the room and tunes power and airflow to hold your set temperature, according to Vornado. You get two heat settings and a fan-only mode, so it earns its desk space in summer too.
Vornado’s vortex airflow aims to spread warmth through small and medium rooms. The case stays cool to the touch, and an automatic safety shutoff is built in.
Vornado’s own page doesn’t publish watts, noise, or dimensions. The size above comes from the Amazon listing. The 5-year “satisfaction guarantee” is Vornado’s phrase, so read the terms before you count on it as a warranty.
Pick it when you’d rather set a temperature once and stop touching the controls.
Buy This If: You want one thermostat setting and a heater that manages the rest. Skip This If: You need a published noise rating or wattage before you buy.
7. De’Longhi Dragon TRD40615E – Best Silent Pick
| Feature | Specification Details |
|---|---|
| Physical Dimensions | 16.4 x 10.3 x 26.1 inches (W x D x H), 25.61 lb |
| Warranty Length | 2 years, per the product page |
| Box Contents | Not published by manufacturer; the listing notes caster wheels |
| Noise Level | No fan; no dB figure published |
The De’Longhi Dragon TRD40615E is the fanless pick. It’s an oil-filled radiator, so there’s no blower to hear on a call. Heat comes from a sealed oil reservoir that never needs refilling, per De’Longhi.
Power runs from 700 to 1500 watts across three settings. A digital panel and a 24-hour timer handle the schedule. Child lock, a thermal cut-off, and an anti-freeze setting are built in.
It’s big. At 25.6 pounds and 16.4 inches wide, it needs a spot on the floor, though caster wheels help. Radiators also warm up slower than fan heaters. De’Longhi’s own page says the unit is only suitable for well-insulated spaces or occasional use. Take that seriously if your office is a cold back room.
You trade speed and floor space for silence.
Buy This If: Your office is well insulated and you can’t tolerate any fan noise. Skip This If: Your room is drafty or uninsulated, or you want heat in the first few minutes.
8. DREO Smart Wall Heater (DR-HSH009S) – Best Wall-Mounted
| Feature | Specification Details |
|---|---|
| Physical Dimensions | 20.08 x 4.72 x 13.39 inches (W x D x H), 9.15 lb |
| Warranty Length | 12 months from the day you buy it (Dreo’s standard policy) |
| Box Contents | Heater body, remote, accessory package, quick start guide, user manual |
| Noise Level | Not published by manufacturer |
The DREO Smart Wall Heater takes no floor or desk space at all. It mounts to the wall and measures 20 inches wide by 4.7 inches deep. Dreo’s wall heater page lists 1500 watts, a 41-to-95°F thermostat with 1°F steps, and a 24-hour timer.
It connects to Wi-Fi, so you can schedule it from your phone or use Alexa and Google Home. The Amazon listing cites a 120-degree oscillation. For more app-controlled gear, see our best smart home ideas.
The catch is the install. You need a wall spot near an outlet, and renters may not want the holes. App control also means a Wi-Fi setup, and Dreo doesn’t publish a noise figure.
It’s the right answer for a tight room where every square foot of floor counts.
Buy This If: Floor space is gone and you can mount a heater to a wall. Skip This If: You rent and can’t drill, or you don’t want an app in your heating.
9. BLACK+DECKER BHDC201 – Best Desktop Heater
| Feature | Specification Details |
|---|---|
| Physical Dimensions | 7.3 x 6.3 x 9.2 inches (W x D x H), 2.8 lb |
| Warranty Length | 1 year |
| Box Contents | Single unit, no additional accessories |
| Noise Level | Not published by manufacturer |
The BLACK+DECKER BHDC201 is a personal heater that sits on the desk and warms you, not the room. It has three modes: fan only, 750 watts on low, and 1500 watts on high. An adjustable thermostat sets the temperature.
Overheat protection and an automatic tip-over shutoff are built in. The cord is six feet long. At 2.8 pounds, it moves from the desk to the floor in one hand.
BLACK+DECKER’s page lists no remote and no timer, and the warranty is one year. It’s a basic heater at a basic price. Don’t expect it to lift the temperature of a cold room.
If your feet are the cold part, read our guide to the best standing desk anti-fatigue mats for hardwood floors.
Buy This If: The room is mostly comfortable and you just need warmth on your hands and torso. Skip This If: You’re trying to heat the whole room, or you want a timer and a remote.
How Many Watts Does a Home Office Space Heater Need?
A 1500-watt heater is the standard ceiling for plug-in space heaters, drawing up to 12.5 amps per Lasko’s spec sheet. That’s enough for most home offices. Lasko rates its 755320 tower for about 150 square feet.
Smaller rooms warm faster. A thermostat then cycles the element off once you reach your set temperature, so a 1500-watt heater doesn’t run flat out all day.
Check your room before you choose a size. A spare bedroom fits any pick here. A converted closet is a better match for a desk-size heater, and our closet office ideas show how others fit one in. Sharing the room? See our home office ideas for couples sharing space for two-desk layouts.
Put the heater on its own outlet when you can. A computer and monitors on the same circuit are fine. A second heater is not.
Ceramic, Infrared, Oil-Filled or Panel: Which Is Quietest on a Video Call?
Oil-filled radiators are the quietest because they have no fan. The fan heaters on this list publish noise figures from 25 to under 40 decibels. Choose oil-filled if you’re on calls all day, and ceramic if you want heat in minutes.
Ceramic and infrared heaters use a blower to push warm air at you. That’s why they warm a room fast and why they make noise. The DREO Atom One lists 37.5 decibels, and the Dr Infrared DR-968 lists 39.
An oil-filled radiator like the De’Longhi heats a sealed oil reservoir, then lets that warmth radiate. It’s slower to start. It’s also silent, which is the reason to buy one.
Wall-mounted panel heaters sit in between. They free up floor space, but you give up the option to move them.
Are Space Heaters Safe to Run at Your Desk All Day?
Yes, if the heater plugs straight into a wall outlet, has tip-over and overheat shutoff, and sits three feet from anything flammable. The U.S. Consumer Product Safety Commission says portable heaters are involved in an average of 1,600 fires a year, with 70 deaths and 160 injuries, from 2019 to 2021.
Three rules come straight from the CPSC’s winter safety guidance:
- Plug into the wall. Never use an extension cord or power strip.
- Keep three feet clear. That means drapes, furniture, and bedding.
- Never run one while sleeping.
Paper stacks and cardboard boxes belong outside that three-foot circle too. Switch the heater off when you leave the room. And check the box for a listing mark such as ETL before you plug it in.
How Much Does It Cost to Run a Space Heater for a Workday?
A 1500-watt heater at full power costs about 27 cents an hour at the U.S. average residential rate of 18.31 cents per kilowatt-hour, per the EIA’s July 2026 data. Eight hours at full power is about $2.20.
Your real cost is lower. A thermostat cuts power once the room reaches your target, so the heater cycles instead of running continuously. Rates vary a lot by state, so check your own bill.
Set the thermostat between 68 and 76°F, the range OSHA recommends for offices. Going higher costs more and buys little comfort.
Products We Considered But Didn’t Include (And Why)
DREO Whole Room Heater 360° Omni (25 dB). It had fewer than 50 ratings on Amazon when we checked. That’s too few owner reports to judge long-term reliability, so we left it out. Revisit it once the review count grows.
Amazon Basics Compact Ceramic Heater. Its Amazon listing showed “See options” instead of an Add to Cart button when we checked. We couldn’t confirm a clean buy route, so it didn’t make the list.
Frequently Asked Questions
Can I leave a space heater on all day at my desk?
Yes, if it’s plugged directly into a wall outlet, has tip-over and overheat shutoff, and has three feet of clear space around it. The CPSC says never to run one while you sleep. Turn it off when you leave the room.
What size space heater do I need for a small home office?
A 1500-watt heater is the standard plug-in size and fits most small offices. Lasko rates its 755320 tower for about 150 square feet. In a closet-size room, a desk-size model like the DREO Atom One is plenty.
Are ceramic or oil-filled heaters better for an office?
Ceramic heaters warm a room faster, but their fans make noise, with published figures between 25 and under 40 decibels on this list. Oil-filled radiators have no fan, so they’re silent, though they heat more slowly. De’Longhi says its radiator suits well-insulated spaces or occasional use.
How much does it cost to run a space heater all day?
At the U.S. average residential rate of 18.31 cents per kilowatt-hour, the EIA reports a 1500-watt heater costs about 27 cents an hour at full power. Eight hours comes to about $2.20. A thermostat lowers that by cycling the heater off.
Can I plug a space heater into a power strip or extension cord?
No. The CPSC says to plug electric space heaters directly into a wall outlet, never an extension cord or power strip, to prevent overloading and fire.
Conclusion
The Bottom Line: Get the DREO Atom One if your office is a spare room or closet. It’s quiet, desk-size, and cheap to run. Move up to the DREO 25-inch tower for a bigger room, or the De’Longhi Dragon if you can’t stand fan noise and your room holds heat.
Whatever you pick, plug it into the wall, give it three feet of clear space, and set the thermostat between 68 and 76°F. If you’re still planning the room, start with our guide on how to set up a home office.
