The best De’Longhi portable heater depends on how you want the heat delivered. For most people the pick is the De’Longhi HCX9115E convection panel heater: quiet, slim, wall-mountable and equipped with a timer. If you want fast heat for a small space, the De’Longhi Capsule is the compact choice, and if you want all-night, near-silent warmth in a bedroom, an oil-filled radiator such as the EW7707CM or the Dragon Digital is better. The rest of this guide shows which type suits which room, and where a rival brand makes more sense.
A note on availability: De’Longhi sells different model numbers in different regions, so this guide only uses the De’Longhi heaters that appear in the current product feed, plus two rival heaters labelled as alternatives.

1. De’Longhi HCX9115E Convection Panel Heater: Best overall
DeLonghi Convection Panel Heater, Full Room Quiet 1500W, portable electric heater is freestanding/easily wall mounted. Energy Saving, quick heat distribution, timer, white, HCX9115E
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Key specs: 1500W; convection panel; timer; energy-saving mode; freestanding or wall-mountable; the listing calls it full-room and quiet. Consumer Reports lists the weight at 15.7 pounds.
Best for: bedrooms, living rooms and offices where you want quiet, whole-room warmth and a clean look. Skip if: you need instant heat, a backlit control panel or a long power cord.
The HCX9115E is the De’Longhi heater that reviewers most often name as the best in the range, and the reasons are consistent. It heats by convection: air passes over a heated element and rises into the room, so on the lower settings there is no fan at all. A long-term blog review calls it silent in convection-only mode, with an audible hum when the fan assist is on its highest setting. It can stand on its feet or hang on the wall using the included kit, which saves floor space and keeps it away from small children and pets.
Features include a digital panel, an adjustable thermostat, a 24-hour timer, an ECO Plus mode and an anti-freeze mode, according to reviewers. Safety includes a tip-over switch and thermal shutoff. Those are the things to confirm on your listing before buying.
There are two caveats from independent sources. Consumer Reports found it heats a standard-size room at a moderate pace but is slow at warming a person sitting in front of it, and it noted the heat outlet can be hot enough to cause pain or a burn on contact, so keep hands and fabrics away from the top vent. Reviewers also note the control panel is not backlit and the cord is short, which may force you to use a close outlet. Do not solve that with an extension cord.
Pros:
- Quiet, with a silent convection mode
- Wall-mount or freestanding
- 24-hour timer, thermostat and ECO Plus
- Slim profile
Cons:
- Hot exhaust outlet
- Short cord and unlit controls
- Slow at warming a seated person
2. De’Longhi Ceramic Tower (TCH7915ER): Best for larger rooms with a remote
DeLonghi Ceramic Tower Space Heater, portable quiet 1500 Electric Space Heater for indoor use, timer, remote, ECO energy efficient, safety features, 24 inches tall, TCH7915ER
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Key specs: 1500W; ceramic tower; 24 inches tall; timer; remote; ECO energy mode; safety features (from the listing).
Best for: a living room or bedroom where you want faster heat than a radiator and the convenience of a remote. Skip if: you want near-silent operation; a fan is part of how it works.
The ceramic tower sits between the fast Capsule and the slow, silent radiators. A fan pushes air across a ceramic element and out of a tall, narrow body, which spreads heat across a wider area than a small cube heater. The listing confirms a timer, a remote and an ECO energy mode, plus unspecified safety features and a height of 24 inches. Its narrow footprint makes it easier to tuck into a corner than a wide panel or radiator.
Fan heaters feel warm quickly because they move air, which is why this suits a room you step into and want warm in minutes. The trade-off is noise, and the fact that the heat stops soon after the fan switches off, because ceramic holds far less warmth than a column of oil. We found little independent testing of this specific model, so treat claims about noise level as unverified, and note that the listing does not publish decibel figures.
Pros:
- Remote and timer
- Narrow, 24-inch tower footprint
- Quick warm-up compared with a radiator
Cons:
- Fan noise
- Little independent testing available
- No stored heat when switched off
3. De’Longhi Capsule (HFX30C15): Best budget and most compact
DeLonghi Capsule Electric Space Heater, 1500w compact and stylized portable space heater for indoor use in office bedroom, thermostat, ceramic heater, fan only option, safety features, HFX30C15
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Key specs: 1500W; ceramic heater with thermostat; fan-only option; compact body; safety features (from the listing). An antifreeze standby setting is described in the retailer text.
Best for: desks, small bedrooms and bathrooms-adjacent spaces where you want quick spot heat. Skip if: you are noise-sensitive or want something for a large room.
The Capsule is the cheapest De’Longhi heater in the feed, and it is built around a simple idea: a small ceramic element and a fan in a compact body. The listing gives it a thermostat, a fan-only mode (useful in warmer weather) and safety features. Because it is small, it is easy to carry between a home office and a bedroom.
The downsides are the ones that come with any small fan heater. It is louder than the panel or radiators, and a customer comment on retailer pages calls it portable but loud. Another reviewer reports it stopped working after two months, which is anecdotal, but it is a reminder that a low-cost heater is a spot-heating tool, not a long-term room heater. Use it with supervision, keep it on a flat floor, and never put it on a bed or soft surface.
Pros:
- Lowest price among De’Longhi picks
- Compact and portable
- Thermostat and fan-only option
Cons:
- Fan noise
- Best only for small spaces
- No timer listed
4. De’Longhi EW7707CM Oil-Filled Radiator: Best for simple bedroom warmth
De'Longhi Oil filled Radiator Heater, 1500W Electric Space Heater for indoor use, portable room heater, Energy Saving, full room like office and bedroom with safety features, EW7707CM
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Key specs: 1500W; three heat settings; manual thermostat; ComfortTemp design; anti-freeze setting; snap-in wheels; reviewers cite a three-year warranty (check the seller).
Best for: bedrooms and offices where silence matters most. Skip if: you want a timer or fast heat.
An oil-filled radiator is the opposite of the Capsule. It heats slowly, holds its warmth for a long time and makes almost no sound. The EW7707CM has no fan and no display, just a dial and three power levels. The ComfortTemp slot design is intended to reduce the surface temperature compared with a solid body. This is the heater to leave in a bedroom overnight at a low setting, subject to the usual safety precautions.
The anti-freeze setting is useful for a spare room, workshop or garage-adjacent space where the goal is to stay above freezing rather than to be comfortable. Remember that the oil does not make the heater cheaper to run: at 1500W it uses the same electricity as any other 1500W unit while the element is on.
Pros:
- Near-silent
- Simple controls and anti-freeze
- Heat lasts after the element cycles off
Cons:
- Slow to warm a room
- No timer listed
- Heavier than a fan heater
5. De’Longhi Dragon Digital: Best for scheduled heat
DeLonghi Dragon Digital Oil Filled Radiator Heater, 1500W Electric Space Heater for indoor use, programmable timer, Energy Saving, full room heater with safety features TRD40615EBK, 16"x10"x26", Black
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Key specs: 1500W; oil-filled; digital controls; programmable timer; energy-saving mode; listing size 16 x 10 x 26 inches (from the listing).
Best for: households that run heat on a routine. Skip if: you want the lightest or cheapest option.
The Dragon Digital is the radiator to choose when you want the heater to run itself. Reviewers describe a 24-hour timer and an ECO Plus mode that adjusts power as the room warms. The thermostat is digital, so the temperature you set is the one you see. It also appears under two near-identical listings, so check the model number before comparing prices.
It is the same technology as the EW7707CM with extra control layers. If you will only turn it on and off by hand, save money and take the EW7707CM. If you want it to warm a home office before work starts, the Dragon earns its premium.
Pros:
- Programmable timer and digital thermostat
- ECO mode
- Quiet, fan-free heat
Cons:
- Premium price
- Slow warm-up
- Heavy for carrying upstairs
6. DREO 1500W PTC Ceramic Heater: Best quiet ceramic (alternative brand)
DREO Space Heater, Portable Electric Heaters for Indoor Use with Thermostat | 2026 Upgraded, 34dB Quiet, 12H Timer, 5 Mode, Remote, 1500W PTC Ceramic Fast Safety Heat for Office Bedroom Home, Gold
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Key specs: 1500W PTC ceramic; thermostat; remote; 12-hour timer; five modes; the listing states 34 dB quiet operation (a manufacturer figure).
Best for: a bedroom or desk where you want fast heat with less fan noise. Skip if: you specifically want De’Longhi.
This is here because the De’Longhi fan heaters in the feed are the louder end of the market. The DREO lists a remote, a 12-hour timer and five modes at a budget price, and states a quiet 34 dB. That figure comes from the listing and has not been independently verified by us, so treat it as a claim. PTC ceramic elements are designed to limit their own temperature, which is a safety plus.
It is a better fit than the Capsule if you want a remote and a timer, and it costs less than the tower. It will not heat a large room, and like every fan heater it stops heating as soon as it is off.
Pros:
- Remote and 12-hour timer
- Stated 34 dB operation
- Low price
Cons:
- Not a De’Longhi
- Small-room heater
7. DREO 4-Mode Oil-Filled Radiator: Best remote oil radiator (alternative brand)
DREO Oil Filled Radiator Heater, Electric Heaters for indoor use Large Room | Quiet, Digital Thermostat, ECO, Remote Control, 4 Modes, Child Lock, Overheat & Tip-Over Protection, 24h Timer, 1500W, Grey
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Key specs: 1500W; digital thermostat; ECO mode; remote; four modes; 24-hour timer; child lock; overheat and tip-over protection.
Best for: a bedroom heater with remote control. Skip if: brand reputation matters more than features.
If you like the idea of the Dragon Digital but want a remote and a lower price, this is the alternative. It matches the De’Longhi’s control list almost point for point and adds a remote. The trade-offs are the usual ones: unknown long-term service, and warm-up speed that is no faster than any other radiator.
Pros:
- Remote, timer and digital thermostat
- Child lock and tip-over protection
- Lower price than the Dragon
Cons:
- Not a De’Longhi
- Slow warm-up
Also Consider
De’Longhi HCX9115E in Asphalt Gray
DeLonghi Convection Panel Heater, Full Room Quiet 1500W, portable electric heater is freestanding/easily wall mounted. Energy Saving, quick heat distribution, timer, asphalt gray, HCX9115E
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
The same convection panel heater as pick 1 in a darker finish. Best for rooms where white would look out of place. The trade-off is the same hot outlet and short cord.
De’Longhi 1500W Radiant Radiator with Mechanical Controls
1,500 Watt Portable Electric Radiant Radiator Heater with Mechanical Controls
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Best for people who want knobs rather than a panel. The listing publishes very little (no dimensions, timer or safety list), so read the full page before buying.
Hykolity 1500W Oil-Filled Radiator with Wide M-Shaped Fins
Hykolity Oil Filled Radiator Heater for Large Room, 1500W Electric Oil Space Heater with 7 Extra-Wide M-Shaped Fins, ECO Mode, 24H Timer, Power Memory, Overheat & Tip-Over Protection for Home Office
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Best for a living room that needs a bigger radiator surface: seven extra-wide fins, a 24-hour timer, ECO mode and power memory. The trade-off is that it is a rival brand with no remote on this version.
One more point on the three extras above: they exist to cover gaps rather than to challenge the main picks. The gray panel heater is simply a colour choice, so buy whichever finish is in stock at a sensible price. The mechanical-control radiator suits someone who has owned a simple radiator before and wants the same thing again, while the Hykolity suits a larger living room where extra fin surface helps the heat feel even. In all three cases, compare the safety list on the listing with the ones in the main picks before you commit.
How We Chose
This guide is based on research, not personal use of the heaters. We started from the De’Longhi heaters currently purchasable in the product feed, then added two rival heaters to cover a quiet ceramic and a remote radiator. We compared the specifications on each listing, retailer pages, and independent reviews including Consumer Reports and long-form owner blogs.
The criteria were heater type (convection, ceramic fan or oil-filled), wattage, noise behaviour, controls (timer, thermostat, remote), documented safety features, portability and how well the specifications are published. We gave extra weight to safety features and to flagging independent complaints, such as the hot exhaust outlet on the panel heater. Where a spec is missing we say it is not listed. We do not quote star ratings, review counts or prices because they change; prices appear only as tiers.
Buying Guide
Which type of heater suits which room?
The type matters more than the brand. A fan heater warms quickly and suits short stays. A convection panel gives quiet, even background heat. An oil-filled radiator warms slowly and holds heat for hours. The table below sets them side by side.
| Type | Speed | Noise | Best room | De’Longhi example |
|---|---|---|---|---|
| Ceramic fan | Fast | Audible fan | Desk, small bedroom | Capsule, Ceramic Tower |
| Convection panel | Moderate | Quiet to silent | Bedroom, living room | HCX9115E |
| Oil-filled radiator | Slow | Near silent | Bedroom, long runs | EW7707CM, Dragon Digital |
How much wattage do you need?
Every heater in this guide is 1500W, the practical ceiling for a standard 120V outlet on a 15-amp circuit. A rule of thumb is about 10 watts per square foot, so one 1500W heater suits around 150 square feet of average insulation, less if the room is cold or the ceiling is high. For larger rooms, a plug-in heater is a supplement, not a replacement for central heating.
| Room size | Suggested type | Notes |
|---|---|---|
| Under 100 sq ft | Capsule or radiator on low | Easy to overheat a tiny room |
| 100 to 150 sq ft | Panel, tower or radiator | The sweet spot for 1500W |
| 150 to 250 sq ft | Panel or radiator as a supplement | Expect a slow warm-up |
| Over 250 sq ft | Central heating plus a heater | One portable unit will not cope |
What does it cost to run?
At full power a 1500W heater uses 1.5 kilowatt-hours per hour. Multiply by your local rate to get the hourly cost. The thermostat means it draws full power only part of the time once the room is warm. Heater type does not change the electricity used per hour at 1500W; it changes how long you need to run it and how comfortable it feels. For a worked method of turning watts into a monthly figure, see this watts and monthly cost walkthrough.
Which safety features are non-negotiable?
Look for tip-over shutoff, overheat protection and a thermostat on every heater, and a child lock if there are children. Plug directly into a wall outlet, keep three feet of clear space around the heater, never cover it, never use it to dry clothes and never leave a fan heater running unattended. Panel heaters can have hot outlets, as Consumer Reports noted for the HCX9115E, so mount high or keep it out of reach of children and pets.
Should you worry about dry air?
Any heater lowers relative humidity as it warms a room. Fans make the sensation stronger. If your throat or skin feels dry in winter, add a humidifier; this site has a guide to winter humidifiers by heating type and room size.
What about bathrooms, garages and pets?
None of these heaters is described as bathroom-rated in the listings, so do not use them where water may splash. For a garage or workshop, use the anti-freeze setting on a radiator only if the space is dry and free of fumes or sawdust. Keep pets and children away from hot surfaces and cords.
Setting Up and Running a Portable Heater Safely
Most heater problems come from placement and habits rather than from the product. Before the first use, read the manual, check the cord and plug for damage, and confirm the outlet is not shared with other high-draw appliances such as a microwave or a space-hungry power tool. A 1500W heater is already using most of what a 15-amp circuit can safely supply on its own, so a second heavy load on the same circuit is how breakers trip and plugs overheat.
Put the heater on the floor, not on furniture, and keep it upright. Place it where air can circulate and where nobody will walk into the cord. If you notice a warm or discoloured plug, a burning smell, or a heater that cuts out repeatedly, stop using it and contact the seller or a qualified electrician. Do not try to repair a heater yourself.
| Habit | Do | Avoid |
|---|---|---|
| Power | Plug straight into a wall outlet | Extension cords and power strips |
| Placement | Flat hard floor, 3 feet of clearance | Beds, sofas, rugs that bunch |
| Running time | Use the timer or thermostat | Leaving a fan heater on while away |
| Cleaning | Unplug and wipe when cool | Wet cloths on a live heater |
| Storage | Dry place, cord loosely coiled | Tightly wrapped cord, damp garage |
Dust is the other everyday issue. Fan heaters pull in dust, and a dusty element can smell when you first switch it on in autumn. Unplug the heater and let it cool, then vacuum the grille gently before the season starts. Oil-filled radiators need only a wipe-down of the outside. If your home is damp rather than dry, remember that a heater lowers humidity only a little; a damp basement or small mobile home needs moisture control as well, and there is a sizing guide for damp small living spaces on this site.
Finally, think about total cost across a season. A cheaper heater that you replace every couple of years is not necessarily better value than a pricier radiator that lasts, but the opposite is also true if you only use a heater a few evenings a year. Match the purchase to the hours you will actually run it: a few hours a week points to the Capsule or the DREO ceramic; nightly use points to a radiator or the panel heater.
Convection Panel vs Oil-Filled Radiator
These two are the usual finalists for a bedroom. The panel heater warms the room faster, can be hung on a wall and weighs less. The radiator is quieter, retains heat longer and does not rely on a hot outlet. If floor space and weight are your constraint, take the panel; if you sleep lightly, take the radiator.
FAQ
What is the best De’Longhi portable heater overall?
The HCX9115E convection panel heater is the most often recommended, thanks to its quiet operation, timer and wall-mount option. Choose the Dragon Digital for scheduled heat and the Capsule for a cheap, compact spot heater.
Are De’Longhi heaters safe to leave on overnight?
Models with tip-over and overheat protection are built for continuous use, but you should not leave any heater unattended near bedding or curtains. Radiators are the usual choice for overnight use because they have no fan and heat gently. For a medical or fire-safety concern, ask your local fire service.
Do De’Longhi heaters use a lot of electricity?
All 1500W models draw about 1.5 kWh for each hour at full power. The thermostat reduces average use once the room is warm. Heat only the room you are in.
Which is quieter, a convection panel or an oil-filled radiator?
Both are very quiet. The radiator has no moving parts and only a thermostat click. The panel heater is silent in convection mode and hums when the fan is on high.
Can I plug a space heater into an extension cord?
Avoid it. A 1500W heater draws around 12.5 amps at 120V, which can overheat thin cords and power strips. Use a wall outlet.
How big a room can a 1500W portable heater warm?
About 100 to 150 square feet with average insulation. Larger or leaky rooms need supplemental heating or draught-proofing.
What is the difference between ceramic and oil-filled heaters?
Ceramic heaters use a fan and heat quickly but stop when switched off. Oil-filled radiators heat slowly, are silent and keep radiating after the element cycles off.
Where can I use a portable heater safely?
On a flat, hard floor, away from curtains, bedding and water, with at least three feet of clearance, plugged straight into the wall.
Which Portable Heater Should You Buy?
If you want one heater and quiet is a priority, buy the HCX9115E. If you want the quickest heat for a small space, buy the Capsule, or the DREO ceramic if you want a remote. For a bedroom you sleep in, take the EW7707CM for simplicity or the Dragon Digital for scheduling. If a remote matters and brand does not, the DREO 4-mode radiator is the value choice. Whatever you buy, plug it straight into the wall and give it space.
