A 300 W infrared heater is a flat electric panel that radiates onto people and surfaces in front of it, with no fan. You are choosing it for a desk, a very small room, or a bathroom wall. You tell them apart by the control and the fixings in the box, a marked BS 1363 plug, and whether a bathroom claim can survive BS 7671. It is 3.8 from eight reviews, and a UK review says the wall hooks were missing. A UK review says that control is separate, and there are only three reviews. What to check before you pay is in the [300 W infrared heater buying guide](/hub/heating/300w-infrared-heater/sub/300w-infrared-heater-buying-guide). Energy Saving Trust’s point is the limit you should keep: you may feel warm in view of the panel while the air elsewhere stays cooler. This size will not replace gas central heating, and it will not heat a normal living room.

The best 300W infrared heaters in detail

Hocosyme GL

Rank 1

Hocosyme GL

∼£90

Our view

The Hocosyme GL is the portable version of the same slim 300 W panel, listed at £89.99 with castor wheels in the bullets and a roller bracket in the title, at 3.72 kg on the same 505 × 595 mm face as the wall listings. amazon.co.uk shows 5.0 out of 5 from two reviews, but the extract has no review text, so that star line should not be read as a UK test win. Coverage is printed twice: 5–8 m² in the heating-coverage field and 3–8 m² in the bullets and highlight, which is the same kind of mismatch as on the larger Hocosyme panels. The bullets recommend a thermostat rather than describing one in the box, and the special-features field lists overheat protection only, with no remote named. IP54 is a bullet, the cable is 1.8 m, and the listing also describes wall-mounted or freestanding use, so you still need a safe fixing if you hang it rather than roll it.

Pros

  • Castor wheels included for moving the panel
  • Lighter at 3.72 kg than the 4 kg wall versions
  • Same 300 W element and 1.8 m cable as the wall listings
  • IP54 claimed, with double overheat protection

Cons

  • Thermostat only recommended, not described as included
  • Coverage lines conflict: 5–8 m² and 3–8 m²
  • Only two ratings and no review text in the file
  • No remote or schedule named in the listing

Best for: A small room where you want to move the panel between spots and will add your own thermostat

Less suitable: Anyone who trusts a 5.0 from two blank reviews, or who needs a schedule in the box at this price

Common questions

Is this panel fixed to the wall?

The title includes a roller bracket and the bullets include castor wheels. The highlight also says wall-mounted or freestanding.

What area does the listing claim?

The heating-coverage field says 5–8 m². The bullets and the highlight say 3–8 m².

Does the listing say it has a remote?

The bullets do not describe a remote. The special-features field lists overheat protection only.

Hocosyme UK-T-300W

Rank 2

Hocosyme UK-T-300W

∼£70

Our view

The Hocosyme UK-T-300W is a 4 kg wall panel listed at £69.99, with a 1.8 m cable and mounting material in the bullets, and amazon.co.uk shows 4.4 out of 5 from three reviews. The special-features field says programmable thermostat, while the bullets tell you to use a thermostat, and a UK review from 24 March 2025 says it needs a separate control, so treat the thermostat line as unproven until you open the box. Coverage is printed as 3–8 m², IP54 is a bullet, and the face is claimed to reach 120 °C, which is hot enough to burn skin if you touch it. One UK buyer treated wheeled feet as an extra of about £29, so castors are not assumed in this listing. At 300 W this is a small-room or local panel, not a living-room heater, and the thin review count means the star line is a hint rather than a test result.

Pros

  • Lowest price in this set at £69.99
  • Wall kit and a 1.8 m cable in the bullets
  • IP54 claimed, with double overheat protection
  • 3–8 m² printed for a very small room

Cons

  • Thermostat wording conflicts; a UK review says control is extra
  • Only three UK reviews
  • Feet were a paid extra of about £29 in one review
  • 120 °C face claim needs clearances

Best for: A small wall-mounted spot if you will add your own thermostat and check the plug on delivery

Less suitable: Anyone who needs a schedule in the box, castors included, or a bathroom install from the listing text alone

Common questions

Does this listing include a thermostat?

What room size is printed?

The bullets and the item highlight say 3–8 m².

What fixing is in the box?

The bullets include mounting material and a 1.8 m cable. A UK review says wheeled feet were an extra of about £29.

Byekalt C-WK-300W

Rank 3

Byekalt C-WK-300W

∼£80

Our view

The Byekalt C-WK-300W matches the basic Hocosyme footprint at 505 × 22 × 595 mm and 4 kg, but the listing at £79.99 adds a remote with 1°C steps and a weekly schedule, stated to work up to 10 metres. amazon.co.uk shows 3.8 out of 5 from eight reviews, a wider sample than the other wall panels here, though the star line is still modest. The English bullets call the panel dust and splash resistant and mention bathrooms, yet they do not print an IP number in the specification table, so treat splash resistance as a claim until the rating plate agrees. A UK review from 4 October 2026 says the wall hooks were missing and steel cables arrived instead, which is a fixings check before you drill. Another UK review ties bathroom fitting to removing the plug for a professional hard-wire. Built-in overheat protection and a 1.8 m cable are listed, with a wall kit claimed in the bullets.

Pros

  • Remote, 1°C steps and a weekly schedule in the bullets
  • Eight reviews, the largest sample among the wall panels
  • Same slim wall format as the cheaper Hocosyme
  • Built-in overheat protection and a 1.8 m cable listed

Cons

  • 3.8 stars, not the highest rating in the set
  • No IP code in the English specification table
  • UK review reported missing wall hooks
  • Bathroom use implies hard-wiring, not a plug beside the bath

Best for: A very small room where you want the printed schedule without buying a separate thermostat

Less suitable: Buyers who need proven wall hooks on delivery, a printed IP code, or a plug-in bathroom install

Common questions

Can you schedule this panel from the listing?

The bullets describe 1°C steps, a weekly schedule, and a remote stated to work up to 10 m.

Does the English listing give an IP code?

No. The bullets say dust and splash resistance and mention bathrooms. They do not print an IP number.

Did a UK review receive the wall hooks?

A UK review on 4 October 2026 says the hooks were missing and steel cables arrived instead.

Könighaus under-desk

Rank 4

Könighaus under-desk

∼£162

Our view

The Könighaus listing at £162.00 is a freestanding 300 W panel shaped for under-desk use, at 16.5 cm deep, 52 cm wide and 56 cm high, and 4.5 kg, with no wall kit required. The bullets describe localised heat for legs and feet, not an entire room, and they print no square-metre figure, which is the honest split from the 3–8 m² wall panels in this set. Control is an integrated on/off switch only; no thermostat, remote, or timer is named, so you manage heat by switching it when you sit down and off when you leave. IP44 is in the bullets and highlight, overheating protection is listed, and a five-year manufacturer warranty is claimed, but cable length is not printed in the extract and amazon.co.uk shows no review line for this ASIN. At 300 W and full power, running cost follows the same rule of thumb as the wall panels, while the purchase price is roughly double the Byekalt wall listing that includes a schedule.

Pros

  • States legs and feet, not a room-size claim
  • Freestanding, with no drilling in the listing
  • IP44 printed in the bullets
  • Overheating protection and a five-year warranty claim

Cons

  • On/off only, with no thermostat or timer named
  • No amazon.co.uk review line in the extract
  • Highest price in this four-listing set
  • Cable length not printed on the UK page

Best for: A desk in a house that is already warm enough, where you want radiant heat on your legs for a few hours

Less suitable: Heating a small room by square metres, anyone who needs a weekly schedule, or bathroom installs from an IP bullet alone

How we compared

Four amazon.co.uk listings are kept. The score uses the star line, the size of the review sample, whether a thermostat, schedule, remote, IP code or fixing is actually described, and the shelf price against that kit. There is no lab test. A missing star line counts as no customer sample. A conflicting thermostat or coverage line, a UK review that reports missing hooks, and a file with no review text each reduce the score. Weights sum to 100. The highest score is the top pick. Best value is a different listing: the lowest price, if you will add a thermostat and accept three UK reviews.

1

Amazon star line

30%

Stars come from the amazon.co.uk file for that ASIN, scored as the rating divided by five, then scaled to 30 points. Byekalt is 3.8 from eight reviews. The basic Hocosyme is 4.4 from three. The portable Hocosyme is 5.0 from two. The Könighaus listing has no star line, so this part scores as no customer sample.

2

Review sample

25%

Every listing here is under 10 reviews, so the sample score stays low. A file with no review text at all is cut further, which applies to the portable Hocosyme. A missing amazon.co.uk review line, which applies to Könighaus, is cut as well. Eight reviews is the largest sample among the wall panels, and it is still a small one.

3

Control and kit

30%

A thermostat or weekly schedule described as included, a remote, castors or freestanding feet, a printed IP code, and a wall kit in the bullets each add points. Byekalt is the only card with a remote, 1°C steps and a weekly schedule. The basic Hocosyme conflicts on the thermostat. A UK review that reports missing wall hooks reduces the Byekalt score.

4

Price against that kit

15%

Shelf price in GBP is read against the control in the box. A complete control under £85 scores higher than a bare panel, and an on/off-only panel above £150 scores lower. Byekalt is about £79.99 with a schedule. The basic Hocosyme is about £69.99 without a proven thermostat. Könighaus is about £162.00 with an on/off switch.

300W infrared heater buying guide

An infrared panel at 300 W is a local heater, not a replacement for central heating. Decide the job before the price. A desk needs heat on your legs. A very small room is the 3–8 m² claim. A bathroom is a zones question, not a bullet that says splash resistant. Then read whether the thermostat or the schedule is actually in the box, and whether a UK review says the hooks or the feet were missing. Star lines on this page are small.

What is a 300W infrared heater?

A 300W infrared heater in this comparison is a flat electric panel. It radiates onto the people and surfaces in front of it, and it has no fan. Energy Saving Trust’s point is the limit you should keep: you may feel warm in view of the panel while the air elsewhere stays cooler. This size will not replace gas central heating, and it will not heat a normal living room. The four amazon.co.uk listings that match the category cost about £69.99 to £162.00.

Best for

  • A desk in a house that is already warm enough, for heat on your legs for a few hours
  • A very small insulated room, if you will add a thermostat rather than leave 300 W on all evening

Not ideal for

  • A living room, or a reading of 98 percent as a saving against other electric heaters
  • A plug-in bathroom install based only on an IP bullet or the word bathroom

Mistakes to avoid

  1. 1

    Using 300 W for a living room

    These panels are a desk or a very small room. Energy Saving Trust’s point is that you may feel warm in view of the panel while the air elsewhere stays cooler. This size will not replace gas central heating.

  2. 2

    Reading 98 percent as a discount

    A printed 98 percent figure, or the word graphene, does not change a 300 W load. Running cost follows the wattage and the hours you leave it on, not a marketing percentage.

  3. 3

    Assuming the thermostat is in the box

    The basic Hocosyme says programmable thermostat in one field and tells you to use a thermostat in the bullets. A UK review on 24 March 2025 says it needs a separate control. The portable Hocosyme only recommends one. The Könighaus unit is on/off only.

What to weigh up

Control and what is in the box

High

Control is how you stop a 300 W panel heating an empty room. Fixed electric local space heaters above 250 W sit under UK ecodesign rules for local space heaters, assimilated Regulation 2015/1188 in Great Britain. A bare on/off switch is a weak way to heat an occupied room. Byekalt’s bullets describe 1°C steps, a weekly schedule and a remote stated to work up to 10 metres, at about £79.99. That is the only schedule described as included.

Bathroom zones, plug and clearances

High

Use a bathroom rule only when that is the room. Section 701 of BS 7671, in the IET’s note, requires at least IPX4 in zones 1 and 2. SELECT’s bathroom guide puts ordinary sockets 2.5 m from the zone 1 boundary and calls for 30 mA RCD protection. NICEIC’s householder page uses IP44 as plain language around baths. A splash word is not a plug-in install beside a bath. On these cards the IP line is a claim. Hocosyme bullets say IP54. Könighaus says IP44.

Which option suits you?

Three typical situations, each with a recommendation from this comparison.

Very small room, with a schedule

You have a very small room and you want the weekly schedule printed in the bullets, rather than buying a separate thermostat. The Byekalt C-WK-300W is the top pick at about £79.99. Check the wall hooks on delivery, and do not treat the splash line as an IP code.

Our recommendation

View offer

Lowest price, own thermostat

You will add your own thermostat and you want the lowest price in this set. The Hocosyme UK-T-300W is best value at about £69.99. A UK review says the control is separate, there are only three reviews, and wheeled feet were an extra of about £29.

Heat at a desk

The house is already warm enough and you want radiant heat on your legs for a few hours, not a room-size claim. The Könighaus under-desk panel states legs and feet. It is on/off only, it has no review line, and it is the dearest listing here at about £162.00.

Common questions about 300W infrared heaters

Which 300W infrared heater is the top pick in 2026?
The top pick is the Byekalt C-WK-300W at about £79.99. In this four-listing set it has the highest score because the bullets include a remote, 1°C steps and a weekly schedule, and eight reviews is the largest sample among the wall panels. The limit is 3.8 stars, no IP code in the English table, and a UK review on 4 October 2026 that says the wall hooks were missing. Best value is the Hocosyme UK-T-300W at about £69.99 if you will add a thermostat.
How much does a 300W infrared heater cost?
On these amazon.co.uk cards the shelf prices run from about £69.99 for the Hocosyme UK-T-300W to about £162.00 for the Könighaus under-desk panel. The Byekalt C-WK-300W is about £79.99. The portable Hocosyme GL, with castors in the bullets, is about £89.99. These are the prices in the listing files, not a live re-check. Wheeled feet on the basic Hocosyme were an extra of about £29 in one UK review, so that cost is not inside the £69.99.
What should you check before you buy a 300W panel?
Check the job first. A panel sold for about 3–8 m² is not the Könighaus unit, which says legs and feet and prints no room size. Then check whether a thermostat or a weekly schedule is described as in the box, not only in one conflicting field. Check the fixings a UK review says were missing or sold extra. Confirm a marked BS 1363 plug and a plate that says 300 W. A splash word in a bullet is not an IP code.
Will a 300W infrared heater warm a living room?
These panels are 300 W, and that load will not heat a normal living room. Energy Saving Trust notes that you may feel warm in view of an infrared panel while the air elsewhere stays cooler, and this size will not replace gas central heating. Hocosyme prints about 3–8 m². The Könighaus listing says legs and feet, not the room. A printed 98 percent figure does not lower the wattage, and graphene does not change the 300 W load.
Can you plug a 300W panel in beside a bath?
A splash line is not a plug-in bathroom install. Section 701 of BS 7671 requires at least IPX4 in zones 1 and 2. Sockets other than SELV stay 2.5 m from the zone 1 boundary, and the circuit needs 30 mA RCD protection. Hocosyme bullets say IP54, Könighaus says IP44, and Byekalt prints no IP code. The zone map is in the bathroom checks. Call an electrician if the panel is inside or near the zones.
How much does 300 W cost to run?
Running cost here is a rule of thumb, not a meter reading of these four panels. Ofgem’s direct-debit electricity rate for 1 October to 31 December 2026 is 26.32 p/kWh in England, Scotland and Wales, with VAT off electricity in that window. Full-power 300 W is about 7.9 pence per hour, and four hours about 32 pence. A 2 kW heater at the same rate is about 53 pence per full-power hour because the load is larger. The panel draws 300 W only while it is switched on.
When is 300 W the wrong size?
Look at a larger panel when the room is bigger than the 3–8 m² printed on the Hocosyme cards, or when you need the air in the room warm rather than warmth on the person in front of the panel. A 300 W load will not do a living room. The next step up in this hub is the 500W infrared heater. Leave this set if you wanted a halogen bar, a fan heater or a convector. Those products were not compared here.

Our verdict

The top pick is the Byekalt C-WK-300W at about £79.99. It has the highest listing score in this set because the bullets include a remote, 1°C steps and a weekly schedule, with eight reviews. A UK review says the wall hooks were missing, and the English table prints no IP code. Best value is the Hocosyme UK-T-300W at about £69.99 if you will add your own thermostat and you accept three UK reviews. Skip the Byekalt if the hooks and a printed IP code have to be certain on delivery. Skip the basic Hocosyme if you need the schedule in the box.
