The best oil radiators, compared.
Top pick: De'Longhi Dragon 4 TRD40820T (2 kW) – Highest listing score, 4.6 from 1,978 reviews, for a 2 kW oil radiator with a thermostat and a 24-hour timer. Best value: Warmlite WL43002YW (650 W) – About £26.00, with 4.0 from 4,116 reviews, the largest sample here, at 650 W for a small room. Updated October 2026.
An oil radiator on amazon.co.uk is a portable electric heater with sealed oil inside metal fins. It warms the room mainly by convection and some radiant heat. You buy one to heat a room the central system misses, to top up a bedroom or home office, or to roll it between rooms on castors. Match the watts to the floor area, then check the thermostat, the timer, tip-over protection and a sound BS 1363 plug. At the same rated wattage, an hour at full power costs the same as a fan heater. Savings come from a lower setting, thermostat cycling and residual warmth after the element switches off. Wattage and controls are in the [oil radiator buying guide](/hub/heating/oil-radiator/sub/oil-radiator-buying-guide). It does not burn oil, and it is not a stand-in for gas central heating across the whole house.

Question 1 of 2
How big is the room?
De'Longhi's Dragon 4 TRD40820T is a 2 kW oil-filled radiator with a mechanical thermostat, anti-frost mode and a 24-hour timer in the listing, plus castors and a carry handle at £149.00. Across 1,978 amazon.co.uk reviews it sits at 4.6 stars, the strongest star line in this comparison, and it carries the top pick badge here on review volume and controls together. UK buyers often describe quiet, steady warmth in bedrooms and living rooms, and many say the thermostat holds a set point once the oil has warmed through. The trade-offs repeat in reviews: the unit is heavy at 14.8 kg on the listing, the mains lead can feel short for a wall socket behind furniture, and some owners report a fiddly mechanical timer or a warm plug after long runs on high. First-use smell or clicking as the metal expands is common to the type and usually fades with ventilation. It is the premium-branded 2 kW choice when you want De'Longhi's chimney-fin design and a large review file, not the lightest radiator to carry upstairs.
Pros
Cons
Best for: A medium bedroom or living room where you want a quiet 2 kW oil radiator with timer and a long review history
Less suitable: Small studies on a tight budget, bathrooms, or anyone who needs instant blast heat

Common questions
Does the listing include a timer?
Yes. The saved listing states a 24-hour timer, with a mechanical thermostat and anti-frost mode.
Is this suitable for a bathroom?
No IP rating appears in the saved amazon.co.uk spec table. Treat it as living-room or bedroom use unless the manufacturer states otherwise.
Does it have castors or handles for moving?
Yes. The listing includes castors and a carry handle. The listed weight is 14.8 kg.
The De'Longhi Dragon 4 TRDSX40820E.WB steps up to an electronic timer and ECO Plus wording in the listing, with the same 2 kW headline and chimney-effect fins at £171.00. It scores 4.5 from 634 reviews, a solid but smaller sample than the Radia sibling in this set. UK reviewers often compare running cost with a fixed wall heater and praise being able to hold 18–20 °C on a lower step rather than full 2 kW constantly. The listing quotes coverage in cubic metres as well as square metres, which is harder to map to your floor plan than a plain m² figure. Weight is 15.6 kg and slow initial warm-up appears in criticism alongside heavy lifting and occasional control confusion. You pay roughly £22 more than the mechanical-timer De'Longhi here for electronic scheduling and the newer Dragon 4 finish. Skip it if a mechanical timer is enough and you would rather put the money toward a higher wattage unit for a cold room.
Pros
Cons
Best for: Shoppers who want De'Longhi build with an electronic timer and ECO mode for a medium room
Less suitable: Tight budgets, small box rooms, or buyers who only heat for quick bursts

Midea's NY2311-25U is an 11-fin oil radiator rated at 2.3 kW with a thermostat, three heat settings and a timer noted in the listing at £83.99. With 4.5 stars from 206 reviews it sits in the upper mid tier for stars, though the review count is modest next to Pro Breeze or Warmlite. UK feedback often mentions quiet running and even warmth in bedrooms and home offices, with tip-over protection stated on the page. Criticism repeats short cable length, a warm plug after long use, first-run smell, and occasional thermostat drift or early faults, which is the usual spread for mid-price oil radiators. At 10.6 kg it is lighter than the De'Longhi pair but still not a one-hand lift. There is no stated room coverage field in the extract, so you size from the 2.3 kW figure and your own m² rule rather than an amazon m² claim. It fits between a 2 kW daily driver and a 2.5 kW lounge heater when you want a named appliance brand without De'Longhi pricing.
Pros
Cons
Best for: A slightly larger or colder room that needs more than 2 kW but not smart features
Less suitable: Conservatories on the cheapest spend, or shoppers who want thousands of UK reviews before buying
Specifications
Common questions
Does the listing include a timer?
The saved listing states a timer. It does not say whether that timer is 24 hours or a weekly programme.
Is this suitable for a bathroom?
No IP rating appears in the saved amazon.co.uk spec table. Treat it as living-room or bedroom use unless the manufacturer states otherwise.
Does it have castors or handles for moving?
Yes. Castors are included. The listed weight is 10.6 kg.
Pro Breeze's white 2.5 kW PB-H packs eleven fins, a 24-hour timer, three heat settings and tip-over protection into a slim chassis at £79.99. It is one of the most-reviewed radiators here at 4.4 stars from 2,679 listings, which gives you a wide spread of UK experience on noise, bedroom use and timer programming. Many owners like steady heat once the oil is hot, though several say the timer dial is not intuitive and that the unit feels heavy at 11.3 kg when you lift it without the castors. Warm plugs, first-use smell and occasional leak or early failure reports appear in the negative bucket, so treat stars as comfort evidence not a safety certificate. The listing mentions app or voice control in one comparison field while bullets describe a classic timer model, so assume manual timer unless the live page confirms smart kit. For a cold double bedroom or open-plan corner where 2 kW feels short, this is the high-wattage value pick with a large review file.
Pros
Cons
Best for: Larger bedrooms, lounges or home offices that need 2.5 kW with a timer under £80
Less suitable: Small 10 m² studies, instant heat before leaving the house, or bathroom placement
Specifications
Common questions
Does the listing include a timer?
Yes. The bullets describe a built-in 24-hour timer. One comparison field mentions app or voice control, which the bullets do not support, so treat the timer as manual unless the live page says otherwise.
Is this suitable for a bathroom?
No IP rating appears in the saved amazon.co.uk spec table. Treat it as living-room or bedroom use unless the manufacturer states otherwise.
Does it have castors or handles for moving?
Yes. Castors are stated. The listed weight is 11.3 kg, and reviews say it is heavy to lift off the wheels.
DREO's DR-HSH010S grey smart radiator is a 2 kW nine-fin model with a digital thermostat, remote, 24-hour timer, child lock and app or voice control stated at £118.99. It scores 4.4 from 1,024 reviews, and UK buyers often highlight quiet running and the convenience of setting modes from the sofa. Listing bullets emphasise layered safety checks and eco modes at 800 W, 1.2 kW and 2 kW, which matters if you want to cap draw on the tariff. Downsides in reviews mirror the category: slow initial warm-up, a short mains lead, warm plugs after long sessions, and setup friction if the app pairing fails. Stated coverage is 10–20 m², a wide band that still asks you to judge insulation yourself. Choose it when you want smart scheduling on an oil-filled body rather than a noisy fan heater; skip it if you will never use an app and a £52 Russell Hobbs 2 kW meets the room size.
Pros
Cons
Best for: Home offices or bedrooms where you want app timers and quiet convection heat
Less suitable: Buyers on the tightest budget, rooms that need 2.5 kW, or anyone avoiding phone setup
Specifications
Common questions
Does the listing include a timer?
Yes. The title and listing state a 24-hour timer, a remote and app or voice control.
Is this suitable for a bathroom?
No IP rating appears in the saved amazon.co.uk spec table. Treat it as living-room or bedroom use unless the manufacturer states otherwise.
Does it have castors or handles for moving?

Russell Hobbs RHOFR5001B is a 1.5 kW seven-fin oil radiator in black with three power steps listed as 600 W, 900 W and 1.5 kW, a variable thermostat, castors and a 1.45 m cable at £42.95. The listing claims about 15 m² coverage and scores 4.3 from 1,366 reviews, a respectable mid sample for a sub-£45 heater. UK reviewers often use it in bedrooms and studies, praising even warmth once warmed through, while complaining about slow first heat, a fiddly timer if they use it, and warm plugs on long runs. At 7.71 kg it is easier to move than a 2 kW eleven-fin tower but still not toy-light. Comparison fields mention app control though bullets describe a dial-and-timer portable, so treat it as manual unless the live listing shows otherwise. It bridges the gap between 650 W budget units and full 2 kW models when your room maths sit around twelve to fifteen square metres.
Pros
Cons
Best for: Double bedrooms and home offices in the mid-teens of square metres on a budget
Less suitable: Open-plan living areas, very cold conservatories, or shoppers who need 2.5 kW headroom
Specifications

This black Pro Breeze PB-H listing matches the white 2.5 kW sibling on wattage, eleven fins, timer and tip-over cut-off, priced at £79.90 on amazon.co.uk. Stars sit at 4.3 but from only 102 reviews, so you get far less UK evidence than the 2,679-review white ASIN in the same table. Early feedback still mentions steady bedroom heat and workable castors, while negatives focus on weight, short leads, smell on first run and isolated reliability issues. Without a large review pool, you are buying the specification sheet—2.5 kW, timer, three settings—more than a crowd-tested story. If colour is the only difference you need, compare live prices and review counts between the two Pro Breeze rows before checkout. Otherwise prefer the white listing for review depth unless this SKU is materially cheaper on the day you buy.
Pros
Cons
Best for: Buyers who want the 2.5 kW Pro Breeze feature set in black and accept a small review sample
Less suitable: Anyone who relies on large amazon.co.uk review counts, or small rooms where 650 W suffices

Warmlite's WL43002YW is a compact 650 W five-fin oil radiator with a thermostat, overheat protection, castors and a carry handle at £26.00. It is the best value badge holder in this set with 4.0 stars from 4,116 reviews—an unusually large count for a budget heater—so you see many UK notes on office corners and spare rooms. Owners like quiet running and low cost, but criticism is blunt: slow warm-up, fiddly controls, short cable, smell on first use, and occasional early failures or inaccurate thermostats. The coverage field in the listing shows opaque numbers rather than a clear m² label, so treat 650 W as suitable for roughly six to eight well-insulated square metres, not a whole lounge. At 2.6 kg it is genuinely portable compared with 2 kW towers. It is the right experiment for a desk zone; it is the wrong sole heater for a family sitting room in January.
Pros
Cons
Best for: Home offices, spare rooms and box bedrooms where 650 W matches the size
Less suitable: Main living room heating, poorly insulated spaces, or buyers who need a digital week timer
Specifications
Common questions
Does the listing include a timer?
A timer field on the saved page says 24 hours. The same file reads more like a dial model, so check the live listing before you rely on a programme.

Russell Hobbs RHOFR5002 delivers 2 kW through nine fins with three settings listed as 800 W, 1.2 kW and 2 kW, tip-over and overheat protection, castors and a 1.45 m cord at £52.00. The listing quotes 20 m² and scores 4.0 from 1,197 reviews, a solid budget-mid evidence base. UK reviewers often place it in living rooms and bedrooms, noting even heat and acceptable noise, while warning about slow start-up, timer confusion where used, and warm plugs if left on high all evening. The saved weight of 3 kg is far below typical nine-fin oil radiators and likely a listing error—expect a normal portable mass when it arrives. Smart control appears in comparison fields without detail in bullets; assume manual operation. It competes with Daewoo and the generic 2.5 kW units on price, trading fin count and brand guarantee for fewer watts than Pro Breeze.
Pros
Cons
Best for: Budget 2 kW heating for medium rooms with Russell Hobbs after-sales expectations
Less suitable: Very large cold rooms needing 2.5 kW, or buyers who trust spec weight literally

Daewoo's HEA1141 is a 2 kW nine-fin portable oil radiator with a thermostat, three heat settings, tip-over cut-off and castors at £41.08. It scores 4.0 from 413 reviews, a middle sample size, and UK buyers often mention garage, office and bedroom use where steady heat matters more than flair. Praise covers quiet running and simple dial control; criticism includes slow initial heating, no timer in the saved listing, short mains lead, warm plugs, smell on first use and occasional thermostat inaccuracy or early failure. At 6.3 kg it is lighter than premium 2 kW towers but still a floor-standing unit, not a fan heater you stash in a cupboard. Listing coverage text is unhelpful in the extract, so size from the 2 kW rating. It is a straightforward warmth machine when you do not need De'Longhi timers; skip it if you require built-in scheduling without buying a plug-in timer separately.
Pros
Cons
Best for: Medium rooms where you want 2 kW heat on a tight budget and can switch off manually
Less suitable: Bedrooms that need a reliable built-in timer, or large lounges on 2 kW alone
Specifications
Common questions
Does the listing include a timer?
No. The saved listing does not state a timer. You switch it off yourself, or you add a separate plug-in timer.

Russell Hobbs RHOFR3001 is a 650 W five-fin black oil radiator with a variable thermostat, tip-over and overheat protection, castors and a stated 10 m² room size at £27.99. Stars are 3.8 from 1,422 reviews—respectable volume but a weaker average than the Warmlite 650 W at £26.00. UK feedback still praises quiet heat in small bedrooms and studies, yet complaints about fiddly timers, short leads, warm plugs, smell on first run and thermostat drift appear often enough to read before you buy. Weight is 2.8 kg, similar portable territory to Warmlite. You pay roughly £2 more than the best-value Warmlite for Russell Hobbs branding and a clearer 10 m² claim. Choose it if the guarantee and brand matter in a small room; choose Warmlite if saved review count and lowest price dominate.
Pros
Cons
Best for: Small bedrooms and studies where 650 W matches the floor area and brand guarantee matters
Less suitable: Main living spaces, buyers wanting the highest star average at minimum price

This Homilec HL-004 listing is a 2.5 kW eleven-fin oil radiator with three power settings, adjustable thermostat, 24-hour timer and tip-over protection at £49.99. The amazon.co.uk line is only 3.8 from 91 reviews, the thinnest evidence in this comparison, and the title omits a household brand while comparison fields leave brand and dimensions blank. Bullets describe a sensible feature set for the price—timer, thermal cut-off, wheels—but you are trusting a newer seller page more than a long UK track record. Review themes mention workable heat and timer programming alongside fiddly controls, short leads, smell on first use and isolated reliability worries. At 11.9 kg it is in the same weight class as other 2.5 kW fins. Treat it as a budget high-wattage option only if the live price undercuts Pro Breeze on the day you order and you accept the small review sample; otherwise favour the Pro Breeze white row with thousands of ratings.
Pros
Cons
Best for: Cost-conscious buyers who need 2.5 kW features and accept a thin review file
Less suitable: Risk-averse shoppers, small rooms, or anyone who wants a major brand and thousands of reviews

Twelve amazon.co.uk listings are kept. The listing score is 80 percent of the star rating plus 20 percent from the review count on a log scale. That is how these scores were built. It is not a lab test. The highest score is the top pick: the De'Longhi Dragon 4 TRD40820T, 4.6 from 1,978 reviews. Best value is a different listing. The Warmlite WL43002YW carries that badge in the product file: about £26.00, the lowest shelf price here, with 4.0 from 4,116 reviews at 650 W. Weights sum to 100.
Amazon star rating
80%Stars come from the amazon.co.uk file for that ASIN. They are 80 percent of the listing score. A high average on a small sample is not treated as a stronger verdict than a slightly lower average on thousands of reviews. The score is not a lab test and not a Which? result.
Review count
20%The review count is 20 percent of the listing score, on a log scale, so a large sample moves the score more than a handful of stars. The Warmlite file has 4,116 reviews. The Homilec file has 91. Early failures in those reviews stay on the record.
An oil radiator is for one room, not for a whole house on electric heat. Match the stated watts to the floor area, then check whether a thermostat, a timer and a cut-out are actually on the listing. Two heaters of the same wattage cost the same per hour at full power. A higher shelf price spends less only if the controls cut the hours. This is not a lab test, and a seller coverage line is not a measured room.
An oil radiator is a portable electric heater with sealed diathermic oil inside metal fins. It warms the room mainly by convection, with some radiant heat from the metal. It does not burn oil, and it is not a stand-in for gas central heating across the whole house. You use one for a single room the central system misses, as a bedroom or home office top-up, or rolled between rooms on castors. Fin counts in this set run from compact five-fin 650 W units to eleven-fin models at 2.3–2.5 kW.
The Warmlite and the Russell Hobbs 650 W suit a small room. A family sitting room in January needs more watts. Undersizing means long runs on high, not a cheaper bill.
At the same rated wattage and full power, the hourly cost matches. Savings come from a lower setting, thermostat cycling and fewer hours. Residual warmth was still paid for as electricity.
Do not dry clothes on the heater, and do not run it from a coiled extension lead. Keep about one metre from bedding and curtains. A hot or discoloured plug means stop.
Start with the room, not the largest number on the box. About 100 W per square metre is a rule of thumb for average ceiling height and insulation, with roughly 10–20 percent more for a cold or tall room. In this set, 650 W is the small-room pair, 1.5 kW is the Russell Hobbs seven-fin, 2 kW covers the De'Longhi pair, the DREO, the Russell Hobbs nine-fin and the Daewoo, 2.3 kW is the Midea, and 2.5 kW is both Pro Breeze listings plus the Homilec.
Castors suit rolling between rooms. They do not make a 15 kg tower easy on stairs. The Warmlite is 2.6 kg and the Russell Hobbs 650 W is 2.8 kg. The De'Longhi pair is 14.8 kg and 15.6 kg. The white Pro Breeze is 11.3 kg. The Russell Hobbs 2 kW file prints 3 kg, which is far below a typical nine-fin oil radiator and should be read as a listing error, not as a one-hand lift. Tip-over or overheat protection is stated on most rows.
Three typical situations, each with a recommendation from this comparison.
You want a 2 kW oil radiator with a thermostat and a 24-hour timer, and you will read a large UK review file. The De'Longhi Dragon 4 TRD40820T is the top pick at about £149.00, 4.6 from 1,978 reviews. Skip it if 14.8 kg is too heavy on the stairs.
A study, spare room or box bedroom is the job, and you want the lowest price with the largest review sample. The Warmlite WL43002YW is best value at about £26.00, 4.0 from 4,116 reviews, at 650 W and 2.6 kg. It is the wrong sole heater for a lounge.
A cold bedroom or lounge still feels short on 2 kW, and you want a 24-hour timer without De'Longhi pricing. The white Pro Breeze 2.5 kW is about £79.99, 4.4 from 2,679 reviews, with tip-over and overheat protection stated. It is heavy at 11.3 kg.
The top pick is the De'Longhi Dragon 4 TRD40820T at about £149.00. It has the highest listing score in this set, 4.6 from 1,978 reviews, as a 2 kW oil radiator with a mechanical thermostat, anti-frost mode and a 24-hour timer. That score is stars plus review count, not a room test. Best value is the Warmlite WL43002YW at about £26.00, with 4.0 from 4,116 reviews at 650 W. Skip the De'Longhi if you need a light carry upstairs. Skip the Warmlite if the room needs around 2 kW.
