The best 800W infrared panel heaters, compared.
Top pick: Hocosyme thermostat Best value: Hocosyme thermostat – Remote and timer at about £129.99, the lowest price in this set with control in the box. Updated October 2026.
An infrared panel heater is a flat, fan-free electric heater for one UK room, not a replacement for gas central heating. The split is what control is in the box. At full output the panel draws 0.8 kWh an hour, about 21p on 26.32p/kWh Direct Debit average for 1 October to 31 December 2026. Energy Saving Trust classes this as direct electric heat, one unit of heat per unit of electricity. It warms people and surfaces in line of sight. A thermostat cuts the hours the element is on. UK buyers of the Smart Dual split on how far the room warms. Room and control are in the [800 W infrared panel heater buying guide](/hub/heating/800w-infrared-panel-heater/sub/800w-infrared-panel-heater-buying-guide). You fix it to a wall, or you use feet or castor wheels when the listing includes them. It heats people and surfaces that can see the face. The Trust also says electricity costs about four times as much per unit as gas, and that evidence for a saving against a standard electric panel heater is thin. Do not treat a marketing line as a draw below 800 W. No duty cycle was measured on these five listings.

Personal buying guide
Question 1 of 2
Where will the panel sit?
The Hocosyme T-WK-800W adds remote and timer control at £129.99, £20 above the bare panel. One UK workshop review praises fast heat-up and silent running, and that buyer still added a Wi-Fi plug thermostat for advance warming. With only two ratings on amazon.co.uk the score is thin evidence, but this is the cheapest way in the set to get onboard temperature buttons without jumping to the Könighaus Smart Dual price. IP54 remains a bullet, not a bathroom wiring plan.
Pros
Cons
Best for: A wall-mounted office or workshop where you want a remote without Wi-Fi.
Less suitable: A bathroom install or anyone who needs many UK reviews before buying.
Specifications
Common questions
Does the Hocosyme thermostat model include a remote?
The bullets describe a remote with a 10 m range and buttons to raise or lower the temperature.
Can it switch on and off on a timer?
The bullets mention timed on and off.
What coverage is printed?
The highlight and bullets say 8–20 m². That is the seller’s range, with the usual insulation caveat, not a measured room.
The portable Hocosyme lists at £119.99 with the same 800 W, 6 kg, 8–20 m² and IP54 claims as the basic wall model, plus castor wheels in the title. amazon.co.uk shows 5.0 from two ratings, but the raw extract has no UK review text to explain those stars. You still need your own thermostat for set-point control. Wheels help room-to-room use, but a wheeled panel still needs clearance around the hot face.
Pros
Cons
Best for: A reader who wants to roll an 800 W panel between rooms and will add a thermostat.
Less suitable: Anyone who needs review evidence or integrated temperature control in the box.
Specifications
Common questions
Does the portable Hocosyme include castor wheels?
The title and bullets describe sturdy castor wheels for easy movement.
Can the portable Hocosyme be wall mounted?
The item highlight says wall-mounted or freestanding. The bullets focus on wheels and a slim panel.
Is a thermostat included with the portable model?
The bullets recommend a thermostat. They do not say one is supplied.
The Hocosyme UK-T-800W is a 6 kg, 2.2 cm wall panel at £109.99 with mounting material and a 1.8 m cable in the bullets. amazon.co.uk shows 4.4 from three UK reviews. One buyer is pleased, one calls the panel flimsy and says warmth stayed local, and one says a thermostat is needed for efficient use. The bullets claim graphene heating and up to 120 °C within a minute, which makes the face a burn hazard if covered. IP54 is a bullet claim only. This is the cheapest 800 W row in the set, but it is still a bare panel until you add control.
Pros
Cons
Best for: A small room if you will add your own thermostat and mount with a clear line of sight.
Less suitable: Anyone who needs onboard control, feet in the box, or proof of bathroom compliance from the listing.
Specifications
Common questions
Does the basic Hocosyme listing include a thermostat?
The bullets recommend a thermostat for optimal use. They do not say one is in the box.
What room size is printed for the basic Hocosyme?
The bullets and the highlight say 8–20 m². Use the low end if the room is leaky or tall.
What IP rating is claimed?
The bullets claim IP54. That is not a bathroom zone decision on its own.
The Könighaus Smart Dual 800 W is the most complete package here at £169.90: Wi-Fi, remote, feet, towel rail, and an IP44 claim. It is also the largest face at 90 × 90 cm and 9 kg. amazon.co.uk shows 4.1 from 159 ratings, but most review texts in the file are non-UK. UK buyers praise the look and instant feel, while others returned units that raised room temperature by only 1 °C or felt slow for the size. One bullet still mentions a 450 W panel while the listing is 800 W. Treat bathroom use as a wiring and zone question, not just IP44 in a bullet.
Pros
Cons
Best for: A reader who wants smart scheduling and a towel rail and will verify bathroom wiring with an electrician.
Less suitable: A tight budget, a large leaky room, or anyone who needs a printed room-size guide on the listing.
Specifications
Common questions
Does the Smart Dual include feet and a towel rail?
The title and bullets include stand feet and an integrated towel rail.
What IP rating is printed on the Smart Dual?
The bullets claim IP44 and dual overheat protection for suitable bathroom and humid indoor environments. That is not a bathroom zone decision on its own.
Is Wi-Fi control included?
The bullets describe Wi-Fi smartphone app control with schedules and an integrated programmable thermostat.
The Könighaus P-800 is a 6.76 kg wall panel at £138.90 with an 11–21 m² guide in the bullets and no thermostat in the box. amazon.co.uk shows 3.5 from 16 ratings, the weakest score in this set. UK texts include useful home-office line-of-sight heat, but also serious complaints: yellowing and charring, a burn mark after first use, and a buyer who calls the unit unsafe. One UK review confirms a UK plug on the panel but criticises a bundled timer with an EU socket. Bathroom appears as a room type without an IP code. This row is for readers who accept external control and who will inspect the panel on arrival.
Pros
Cons
Best for: A home office where you want Könighaus branding and will add your own thermostat.
Less suitable: Anyone alarmed by burn-mark reviews, or anyone who needs control and towel-rail features in the box.
Specifications
Common questions
Does the Könighaus P-800 include a thermostat?
The bullets say to use a suitable external thermostat and that the thermostat is not included.
What area does the P-800 listing claim?
The bullets say about 11–21 m² for the 800 W size. The coverage field says 8–21 m². Both are seller lines, with an insulation caveat.
What do UK reviews say about P-800 safety?
Several UK reviews in the file report burn marks, yellowing, warping or charring. Those are stop-using signals, not normal running-in.
Five amazon.co.uk listings are kept. The listing score uses whether a thermostat, remote or Wi-Fi schedule is in the box, the UK star line and review text, the mount and the seller’s coverage line, and the shelf price against that package. There is no lab test. Two or three reviews are thin evidence. Review texts that are not from the UK are not treated as British shopper consensus. Weights sum to 100. The highest listing score is the Hocosyme remote model, and that is the best value award. The top pick is the Smart Dual because it is the only complete package, even though its listing score is lower.
Control in the box
30%A thermostat, remote or weekly schedule has to be in the listing, not only recommended. The basic and portable Hocosyme models, and the Könighaus P-800, tell you to add an external thermostat. The Hocosyme thermostat model includes a remote and timer. The Smart Dual includes Wi-Fi and an onboard schedule. Overheat protection is a cut-out, not a set point.
UK review evidence
30%Stars and the review count come from the amazon.co.uk file for that ASIN. The Smart Dual is 4.1 from 159, and most written reviews in the file are not from the UK. The P-800 is 3.5 from 16, with UK texts on yellowing, burn marks and charring. The Hocosyme thermostat and portable models have two ratings each. The basic wall panel has three.
Mount and coverage
20%Wall kit, wheels or included feet, and the seller’s square-metre line, are read with the insulation caveat. Hocosyme prints 8–20 m². The P-800 prints about 11–21 m² in the bullets and 8–21 m² in a coverage field. The Smart Dual extract has no square-metre figure. An IP44 or IP54 bullet is recorded as a claim, not as bathroom permission.
Price against the package
20%Shelf price in GBP is read against what the box contains. The basic Hocosyme is £109.99 without a thermostat. The remote model is £129.99. The Smart Dual is £169.90 with Wi-Fi, feet and a towel rail. A lower price with no control in the box does not decide best value.
An 800 W panel is one room of direct electric heat, not a whole-house system. Decide the control in the box, the mount, and whether the seller’s coverage line still fits after you allow for a leaky or tall room. Prices here run from about £109.99 to £169.90. This is not a lab test.
An 800W infrared panel heater is a flat electric panel for one room. It has no fan. You fix it to a wall, or you use feet or castor wheels when the listing includes them. It heats people and surfaces that can see the face. It is not a replacement for gas central heating across the house. Energy Saving Trust classes infrared as direct electric heat: about one unit of heat for each unit of electricity.
Full output is 0.8 kWh an hour, about 21p on the Ofgem Direct Debit rate used here. A marketing line about savings is not a measured duty cycle. A thermostat only helps by cutting the hours the element is on.
Hocosyme prints 8–20 m² and Könighaus prints about 11–21 m² for the P-800, with an insulation and ceiling-height caveat. The Smart Dual extract has no square-metre figure. A leaky or tall room sits at the low end, or below it.
Those are bullets. Zone 1 still needs fixed, permanently connected equipment the manufacturer approves. SELECT’s guide keeps 13 A sockets outside the zones. UK P-800 reviews that report burn marks or charring are a reason to stop and return the panel.
Start with what you can set a temperature with. The basic Hocosyme UK-T-800W at about £109.99 and the portable model at about £119.99 only recommend a thermostat. The Könighaus P-800 at about £138.90 says the thermostat is not included. The Hocosyme thermostat model at about £129.99 puts a remote, a timer and temperature buttons in the bullets. The Smart Dual at about £169.90 adds Wi-Fi, a weekly schedule, feet and a towel rail. Mount next.
Quote a room size only as the seller’s range. Hocosyme prints 8–20 m² on all three listings. The P-800 bullets say about 11–21 m² and a coverage field says 8–21 m². A rule of thumb of 25–35 W per cubic metre puts 800 W near 23–32 m³ in a post-1980 home. DESNZ finds comfort most sensitive to line of sight, so a panel behind a sofa does not warm the person in the chair. Regulation 35 requires a BS 1363 plug for this use.
Three typical situations, each with a recommendation from this comparison.
You want radiant heat on one zone and a remote, without paying for Wi-Fi. The Hocosyme thermostat model is best value at about £129.99, with a timer and temperature buttons. amazon.co.uk shows only two ratings, and one workshop buyer still added a Wi-Fi plug.
You will add a thermostat and you want the lowest shelf price. The Hocosyme UK-T-800W is about £109.99, with a wall kit and 8–20 m² in the bullets. The thermostat is recommended, not included, and the star line is three reviews.
You want feet, a towel rail and a printed IP claim, and an electrician will check the zone. The Könighaus Smart Dual 800 W is the top pick at about £169.90, with an IP44 bullet. That bullet is not permission to fit it in zone 1 on a 13 A socket.
The top pick is the Könighaus Smart Dual 800 W at about £169.90. It is the only complete package in this set: Wi-Fi, a remote, feet and a towel rail, with 4.1 from 159 amazon.co.uk ratings. Many of those review texts are not from the UK, and UK buyers disagree on how far the room warms. Best value is the Hocosyme remote and timer model at about £129.99, with only two ratings. Skip the P-800 if UK reports of burn marks and charring are a concern. Skip the Smart Dual if you need a printed square-metre guide on the listing.
