An electric heater has one number that decides what it costs to run and how much room it warms, and that number is wattage. Every listing here knows it, every title carries it, and when the specification table is asked for the heat output it answers with something else entirely. The Dreo at £59.99 says thirty-five degrees Celsius. The Amazon Basics at £34.19 says forty-one degrees Fahrenheit. The same Dreo says sixteen kiloamps, which is sixteen thousand amps and would need a substation rather than a three-pin plug. Three products, three answers to the same field, and not one of them is the number a buyer came for.
The wattage is not hidden, it is somewhere else — in the title, in the bullets, and in the power settings, which is exactly where the contradictions live. The Belaco convector is advertised as a two thousand watt heater, with a specification table that gives its heat output as seven hundred and fifty watts, the lowest of the three settings the same page lists. And one Warmlite fan heater appears twice in this article's market, in two listings with identical titles, one declaring a thousand watts and the other two thousand — two numbers for the same machine, and two different rating pools behind them.
The sizing field is worse, and it is the one a buyer actually needs, because a heater is bought for a room. To judge that you need an area, and this market answers with no unit at all — seventy, then one hundred and eighty — with square feet, with a range, with an abbreviation, with a hedge (two hundred square feet, estimated), with an adjective (small slash medium), and in the case of the cheapest heater here, with nothing: the Amazon Basics at £9.90 has no coverage field at all. The only metric figure anywhere in this article is in a bullet, where a different Amazon Basics says it covers up to eighteen square metres — which is twenty-three square feet more than the listing beside it claims, in a unit that the rest of the market refuses to use.
None of that makes these bad heaters, and at these prices it should not. What it means is that the numbers worth trusting are the ones a seller cannot round or relabel: the rating count, the distribution behind it, and the wattage printed in the title. Two of the last three are visible in one field here, and it is the one field nobody fills in by accident — the best sellers rank, where the £9.90 Amazon Basics reports itself as fifth in electric heating, and the BZGG as twenty-fourth.
Warmlite Thermo Fan Heater with 2 Heat Settings
£13.29 with 14,094 ratings — and a twin listing that gives the same heater a different wattage.
Advantages
- 14,094 ratings at 4.0 stars: eight times the next sample here
- £13.29: the cheapest serious heater in the article
- Two power settings and three heat levels
- 1.12 kilograms, with a tip-over cut-out
Disadvantages
- 13 per cent of buyers give it one star
- Its twin listing declares a different wattage
- Heating coverage is seventy, with no unit
- 4.0 stars is the lowest average of the big samples
The cheapest heater here that is not the £9.90 Amazon Basics, and the one with the most evidence behind it by a distance: fourteen thousand and ninety-four ratings at 4.0 stars, which is eight times the next-largest sample in this article. It is a fan heater with two power settings and three heat levels, a manual dial, overheat protection and a tip-over cut-out, weighing 1.12 kilograms and measuring twenty-three by fifteen point seven by twenty-six and a half centimetres. For a small room, it is the volume answer — and it is also the article's best example of why the specification table cannot be trusted.
The same heater is sold in a second listing, with the same title and the same bullets, and the two pages disagree about its heat output: this one says two thousand watts, the other says a thousand. Both bullets describe the product as having settings of 1000W and 2000W, so neither number is a lie and neither is an answer — one page picked the top of the range and the other picked the bottom. The rating counts disagree too: nine thousand three hundred and eighty-two on one page and fourteen thousand and ninety-four on this one, which means the same physical heater has two review pools and this listing has the larger one. A buyer comparing the two pages is comparing two versions of a machine that does not have two versions.
The heating coverage field says seventy, with no unit, which is the other habit this market has. Seventy square metres would make this a heater for a large living room; seventy square feet would make it a small office. The listing does not say which, and at £13.29 with a 4.0 star average and thirteen per cent of buyers at one star, it is the kind of product whose job is to be cheap and warm rather than specified. Buyers describe it as blowing out really warm air, easy to use, and useful in dual purpose — one of them, with two spelling mistakes in a single sentence, calls it value for money anyway.
Dreo Smart Electric Heater, 1500W Silent Room Heater
£59.99 with 1,431 ratings and the cleanest distribution here — and a current draw of sixteen kiloamps.
Advantages
- 4.6 stars with 77 per cent five-star: the best distribution here
- A thermostat from 5 to 35 degrees Celsius
- 1,431 ratings, and only 4 per cent at one star
- 1500W with a ceramic element and 16-hour timer
Disadvantages
- £59.99: the dearest heater in the article
- The current draw says sixteen kiloamps
- Heating coverage is a 300-400 square foot range
- The sample is a tenth of the warmlite's
The best rating in this article among the products with a sample worth reading, and the one with the strangest field on the page. Four point six stars from 1,431 ratings, with seventy-seven per cent at five and four per cent at one, which is the cleanest distribution here and the reason this heater sits second on a list where the two big sellers are both at 4.0. It is a 1500 watt convection heater with a ceramic element, a thermostat that can be set between five and thirty-five degrees Celsius, a sixteen-hour timer and a gold finish, and it is the most expensive thing in the article at £59.99.
Its specification table lists the current draw as sixteen kiloamps. Sixteen thousand amps, at 230 volts, would be three and a half megawatts — the supply to a small industrial unit rather than a heater that plugs into a wall. The number is almost certainly sixteen amps with a prefix that did not belong, and the same table's neighbours show how easy the error is to catch: the two Belaco convectors in this article state 8.33 and 9.09 amps, without any prefix at all. It is the same class of mistake as the dehumidifier articles on this site, where a floor area field claims coverage of one square foot and two thousand square feet on the same page, and it is worth noticing that it appears on the most expensive and best-rated heater here.
Two other fields are worth a look. The heating coverage is given as a range — three hundred to four hundred square feet, which is twenty-eight to thirty-seven square metres, and a range is an honest way of saying the page does not know. The heating method says convection, which is right, and the element says ceramic, which is right. At £59.99 with a 4.6 star average and a four per cent one-star share, this is the heater to buy if the room is a bedroom, the noise matters and the budget is not the argument. Its sixteen kiloamps are a typographical problem, not an electrical one.
Belaco 2000W Portable Convector Heater
£18.99 with 1,729 ratings — a 2000W heater whose specification names its own lowest setting as the output.
Advantages
- 1,729 ratings at 4.0 stars for £18.99
- Three heat settings: 750W, 1250W and 2000W
- An adjustable thermostat up to 40 degrees
- 8.33 amps, which checks out against the 2000W title
Disadvantages
- 15 per cent of buyers give it one star
- The heat output field says 750 watts
- Coverage is 200 square feet, estimated
- The element field says radiant on a convector
The cheapest convector in this article, the worst-rated of its big samples, and the clearest example of a page arguing with itself. The title says two thousand watts. The bullets say the heater has three settings — 750, 1250 and 2000 — which is consistent and useful. The specification table, asked for the heat output, answers with seven hundred and fifty watts: the lowest of the three settings, published as though it were the product's power. Fifteen per cent of its 1,729 buyers give it one star, which is the heaviest one-star share in this article and worth knowing before the price persuades anybody.
Its coverage field carries a different kind of honesty. It says two hundred square feet, estimated — the word estimated inside a specification field, by the seller, is the market admitting that it does not know how big a room the machine heats. The same field on other listings in this article gives a bare number with no unit, a range, an abbreviation, or an adjective, and one heater has no coverage field at all. This one at least says what it is guessing.
The rest of the table is what a budget convector looks like. The heating method is convection, which is correct for the product, and the element field says radiant, which is not — radiant is the other family of heater, and the same field on this article's two ceramic heaters says radiant as well, which is why this site treats element fields as decoration. The voltage is given as 220, with no unit, against 230 and 240 volts on the listings beside it. The amperage is 8.33, which is correct for 2000 watts at 240 volts and is a useful cross-check on the title. Three heat settings, a thermostat up to forty degrees, an adjustable thermostat and a two-year guarantee are what seven hundred and fifty watts buys — or two thousand, depending on which line of the page you read. One buyer thanks the seller for a replacement, which is not what a product page puts in its own highlights.
BZGG 1000W Portable Room Heater
£16.98 and 1,000 watts — the lowest power here, with the second-cleanest distribution and Amazon's JavaScript in a spec field.
Advantages
- 4.5 stars from 1,211 ratings at £16.98
- 77 per cent five-star and 6 per cent one-star
- The wattage is in the title: 1000W
- A published sales rank: 24th in electric heating
Disadvantages
- A thousand watts will not heat a large room
- The coverage field abbreviates its unit
- The heating method field says radiant
- The review field holds Amazon's JavaScript
The lowest wattage in this article and one of its best records: 1,211 ratings at 4.5 stars, with seventy-seven per cent at five and six per cent at one, which is the second-cleanest distribution of the eight heaters here and it belongs to a product costing £16.98. A thousand watts is half the power of the two thousand watt convectors above it, and it is the number the listing puts in its own title — which makes it the only page in this article that leads with the figure that decides the bill.
Its fields show the same carelessness as everything else here, in a slightly different order. The heating coverage says two hundred square feet, abbreviated, which is the sixth convention this article has found for one field: a bare seventy, a bare one hundred and eighty, two hundred and fifty square feet, a three to four hundred range, an estimate in brackets, an adjective, and now this. The heating method says radiant, which is what a panel heater claims and not what a fan-assisted ceramic heater is, and the review field is not a rating at all but a fragment of Amazon's own page code — the stars, the count, then a variable name and a script trigger trailing off into the widget. This site has now found that same leak on an air mattress and a sleeping bag, which makes it a habit of Amazon's own template rather than a seller's mistake.
What this listing has that no other heater here does is a sales rank: six thousand eight hundred and eighty-eight in Home and Kitchen and twenty-fourth in electric heating, published by the page itself, which is a claim about how many people bought it that no field can round. Buyers describe it as providing a decent amount of heat for such a small product and as a lovely little heater with two heat settings, which is the other side of a thousand watts: it will not heat a living room, and nobody who bought it expected it to.
Amazon Basics 1800 Watt Ceramic Space Heater
£9.90 with 409 ratings — the cheapest here, and the only listing that gets both the watts and the voltage right.
Advantages
- £9.90: the cheapest heater in the article
- 409 ratings at 4.4 stars, only 4 per cent at one
- Heat output and voltage both stated correctly
- Its own page reports fifth in electric heating
Disadvantages
- No heating coverage field at all
- The element field says radiant on a ceramic heater
- 409 ratings is a modest sample
- Three output modes and no thermostat display
The cheapest thing in this article, at £9.90, and the only heater here whose specification table answers the two most important questions correctly. Asked for the heat output it says eighteen hundred watts, which is a number about electricity. Asked for the voltage it says two hundred and forty, which is the number a British socket supplies. Every other listing in this article fails at least one of those: thirty-five degrees Celsius, forty-one degrees Fahrenheit, sixteen kiloamps, seven hundred and fifty watts against a two thousand watt title, one hundred and twenty volts. None of those failures costs ten pounds to avoid.
Its coverage field does not exist. The page has no heating coverage at all, which makes it the eighth convention in a table that has already produced a bare seventy, a bare one hundred and eighty, two hundred and fifty square feet, a range, an estimate in brackets, an abbreviation and an adjective. A missing field is not a specification, but it is at least not a misleading one, and for a nine pound heater sold with three output modes — low, high and fan only — the honest answer is that it heats the room you put it in.
The page's most useful line is one it did not have to write: a best sellers rank of fifth in electric heating, against one thousand three hundred and twenty-eight in the wider home and kitchen category. Nobody types that accidentally. It is the cheapest heater here, it has 409 ratings at 4.4 stars with seventy-one per cent at five and four per cent at one, and its own page says it is the fifth best-selling heater in the category. Its element field says radiant, which it is not — this is a ceramic fan heater, as the title says — and that is the only field on this page that argues with the product.
Belaco 2000W Turbo Convector Electric Heater with Fan
£29.98 with a 24-hour timer and a 5 per cent one-star tail — the Belaco that states its wattage correctly.
Advantages
- 156 ratings at 4.4 stars, with only 5 per cent at one
- The heat output says 2000 watts, correctly
- A turbo fan, three heat settings and a 24-hour timer
- Two kilograms: movable between rooms
Disadvantages
- 156 ratings is a mid-sized sample at best
- The type field says heater
- £29.98 against £18.99 for the sibling without a fan
- 230 volts stated, against 240 on the Amazon Basics
The second Belaco in this article and the one that gets its own numbers right. Its heat output field says two thousand watts, which agrees with its title and with the three heat settings its bullets list, and its voltage says two hundred and thirty. Its sibling at number three, made by the same company with the same three settings, publishes seven hundred and fifty watts in the same field — which is the cheapest possible illustration of the point this article is built on: the field is filled in per listing, by a person, and only sometimes by someone who read the product.
What the £29.98 buys over the £18.99 sibling is a fan. The Belaco Turbo is described as a turbo fan assisted convector with three heat settings and a twenty-four hour timer, weighing two kilograms and measuring twenty by fifty-three by thirty-eight and a half centimetres, and it carries 156 ratings at 4.4 stars with sixty-nine per cent at five and five per cent at one — the cleanest one-star tail of the mid-sized samples here. A convector without a fan heats by convection alone, slowly and silently; the fan is what turns it into a machine you can feel within a minute, and it is the honest difference between the two Belacos in this ranking.
The rest of the table is ordinary. Its type field says heater, which is the object's own name rather than a type, and it joins a small family of fields on this site that describe the product by repeating the product: a mattress whose specific use is bed, an airbed whose shape is standard mattress. Its item highlight lists three heat settings and a twenty-four hour timer, which is what the product has. At £29.98 it sits in the middle of this article, between the £18.99 convector and the £34.19 fan heater, and it is the one we would pick of the three if the room is used in the evening and the difference between warm in ten minutes and warm in twenty matters.
Amazon Basics Space Heater with PTC Ceramic Technology
£34.19 — heat output written in Fahrenheit, voltage written for America, and the only square metre figure in a bullet.
Advantages
- PTC ceramic element with a two-second heat-up
- Forty decibels on the low setting, stated
- A 24-hour timer, a remote and an ECO mode
- Eighteen square metres, in the bullets
Disadvantages
- 11 per cent of buyers give it one star
- Heat output is written in Fahrenheit
- Voltage is 120, which is not a UK socket
- Coverage is 180 with no unit in the field
The most instructive listing in this article, because every one of its faults is the kind a buyer can catch in ten seconds and none of them is in the product. Its heat output field says forty-one degrees Fahrenheit. Its voltage says one hundred and twenty volts, alternating current, which is a socket in the United States and not one in Britain. Its maximum temperature setting is ninety-five degrees Fahrenheit, which is thirty-five Celsius and would have been clearer written that way, since its minimum on the same page is five degrees Celsius. Two units and two countries in a single table, on a heater sold to British buyers.
The room size is where the same page accidentally becomes the honest one. Its coverage field says one hundred and eighty, with no unit, like two of the other listings here. But its first bullet says the heater covers up to eighteen square metres, which is a figure in the unit this country actually uses and the only metric area in the whole article. Eighteen square metres is a large bedroom or a small living room, and it agrees with a heater whose specification claims one hundred and eighty — if the field had meant square feet, which is what the rest of this market writes in. The buyer who reads only the table gets a number; the buyer who reads the bullets gets an answer.
The rest of the page is good. The element is PTC ceramic, the method is forced air, the bullets promise a two-second heat-up, five modes including ECO, a twenty-four hour programmable timer, a remote and a digital display, and noise of forty decibels on the low setting — which is the sort of figure no specification field here carries. It has 110 ratings at 4.3 stars, with seventy-one per cent at five and eleven per cent at one, and one of its two reviews is the best sentence in this article: the buyer says it warmed up a room that was bigger than the stated maximum. That is what a coverage field is worth.

Final Verdict
What we would buy. The £13.29 Warmlite is the one we would buy, and the argument is volume of evidence: fourteen thousand and ninety-four ratings, eight times the next sample in this article, on the cheapest heater here that is not the £9.90 Amazon Basics. It is a fan heater with two power settings and three heat levels, it weighs 1.12 kilograms, and its table gives its heat output as two thousand watts with a heating coverage of seventy — of nothing. If the room is a bedroom or an office and the noise matters, the £49.99 Dreo Smart is the one to take: 1,431 ratings at 4.6 stars with seventy-seven per cent at five is the best distribution here, its thermostat holds between five and thirty-five degrees, and its table's sixteen kiloamps are a typo rather than a warning. If the budget is the whole argument, the £9.90 Amazon Basics is the cheapest thing in the article with 409 ratings at 4.4 stars, and it is the one heater here that reports its own sales rank — fifth in electric heating. If a convector is what the room needs, the £18.99 Belaco is the cheapest of those, with 1,729 ratings and a warning of its own: fifteen per cent of its buyers give it one star, the worst share here. And the Belaco convector is also the one we would leave, for the same reason — one buyer in seven rating it a single star, on a page that cannot agree whether the heater draws two thousand watts or seven hundred and fifty.
What the listings will not tell you. Read the wattage in the title and check it in the bullets, because the heat output field cannot be trusted: here it says thirty-five degrees Celsius, forty-one degrees Fahrenheit and sixteen kiloamps, and one heater answers a thousand watts in one listing and two thousand in another. Do not size a room from the coverage field until you have found its unit — this market writes seventy, one hundred and eighty, two hundred and fifty square feet, three hundred to four hundred square feet, two hundred square feet estimated, two hundred square feet abbreviated, an adjective, and nothing at all. Convert before you compare: two hundred and fifty square feet is twenty-three square metres, and a heater sold for a small office may be described in a unit this country does not measure rooms in. Check the voltage if the listing looks imported, because one here is specified at a hundred and twenty volts, which is not a socket in a British house. Look at what the element field claims against what the title says, since this article has a coil in a ceramic heater and radiant panels in two convectors. And weigh the rating against the sample: a 4.4 from 409 buyers is not a better heater than a 4.0 from fourteen thousand, it is a page that fewer people have found.
Why trust this ranking?
We rank on price, customer ratings and the specifications that decide the job, and we read each specification table against the marketing bullets on the same listing. When a number does not survive that check, we say so in the entry rather than quietly dropping the product. We also say when a product is the wrong one for you.
