The best infrared picture heaters, compared.
Top pick: Klarstein HTR10-WdwlS500wStarN Best value: Klarstein HTR10-WdwlS350W Wave – About £173.49, 350 W on a 60 × 60 cm face, the lowest price among the listings that print watts. Updated October 2026.
An infrared picture heater is a mains electric radiant panel with a printed image. You hang it like a picture so it warms the people and surfaces it faces. It suits a living room, bedroom or home office where another heat source already exists. It is not a cheaper form of electricity than any other heater of the same watts, and it is not a medical device. None of the four files prints a BS 1363 plug. At the Ofgem Direct Debit average of 26.32 p/kWh, full power is about 9 p an hour at 350 W and about 18 p at 700 W, before the standing charge. Watts, thermostat, print and plug are set out in the [infrared picture heater buying guide](/hub/heating/infrared-picture-heater/sub/infrared-picture-heater-buying-guide). You can feel warm in front of the panel while the air stays cooler, and a cold room can still condense. Energy Saving Trust treats infrared as direct electric heat and says not to swap a whole-house gas system for it, because electricity costs about four times gas per unit of energy. A picture panel of a given wattage is the same class of electric heat as any other heater of those watts.

Question 1 of 2
How large is the wall you sit facing?
The Klarstein Starry Night at £214.19 is an 80 cm by 60 cm panel, 5 cm deep and 4.8 kg, listed at 500 W for 10 m². Amazon.co.uk shows 5.0 out of 5 from 3 ratings. Both written reviews in the file are marked Germany, so five stars here is a thin count, not a UK test, and it does not outweigh 4.0 from 60 on the 700 W file. The room-type field says bathroom and a bullet claims IP44, while indoor/outdoor says indoor and the plug standard is blank. The power-source line prints corded electric and solar powered, but the included parts do not list a solar panel. A listing question asks whether it works without Wi-Fi and stores no answer, and the spec table does not name a remote. Full power is about 13 p an hour at 26.32 p/kWh before the standing charge.
Pros
Cons
Best for: Someone who wants the Starry Night print for about 10 m² and will have an electrician check any bathroom plan
Less suitable: A shopper treating three five-star ratings as proof, or anyone who wants to plug the panel in beside a bath
Specifications
Common questions
Does the listing claim bathroom use?
The room type is bathroom, and a bullet claims IP44 plus wet-room use. Indoor/outdoor says indoor. The plug standard is not printed.
Does the file show a solar panel?
Power source prints corded electric and solar powered. The included components list the heater, mounting material and a manual. They do not list a solar panel.
What happens if there is no Wi-Fi?
The listing asks whether it works without Wi-Fi and does not store an answer. A bullet says temperatures are set in the Klarstein app. A remote is not in the spec table.
The Klarstein Blue Wave at £254.69 is the widest print in this set: 120 cm by 60 cm, 5 cm deep and 7.1 kg, listed at 700 W for about 10–15 m². Amazon.co.uk shows 4.0 out of 5 from 60 ratings, the only sample here that is more than a handful of reviews. The written reviews in the file are marked Germany or the Netherlands, so that average is a count on the UK listing, not British owner testimony. A bullet claims a thermostat, a Wi-Fi app and IP44, the room-type field says living room, and wet rooms appear among recommended uses. The spec table does not name a remote, the plug standard is not printed, and 7.1 kg is more than a picture hook should carry on plasterboard. The 37 °C line is the maximum setting on the file, not a measured surface temperature. At the Ofgem Direct Debit average of 26.32 p/kWh for 1 October to 31 December 2026, full power is about 18 p an hour before the 54.83 p/day standing charge.
Pros
Cons
Best for: A larger sitting wall where you want the 120 cm print and you already heat the house another way
Less suitable: A small bedroom the 350 W file already covers, or a bathroom you intend to plug into
Specifications
Common questions
Does the listing claim bathroom use?
Recommended uses include wet rooms, and a bullet claims IP44. The room type field says living room, and indoor/outdoor says indoor. The plug standard is not printed.
What area and weight are printed?
Heating coverage is printed as approximately 10–15 m². Dimensions are 5 cm deep by 120 cm wide by 60 cm high. Weight is 7.1 kg.
Is a remote in the spec table?
The spec table does not list a remote. A bullet says the Klarstein app programs the heater over Wi-Fi, and the title and a bullet say a thermostat is included.
The Klarstein Blue Wave at £173.49 is a 60 cm by 60 cm wall panel, 5 cm deep and 3.6 kg, listed at 350 W for up to 7 m². Amazon.co.uk shows 3.6 out of 5 from 6 ratings. The two written reviews in the file are marked Germany, so that star line is not a UK owner verdict. A bullet claims a thermostat, a Wi-Fi app and IP44, and the room-type field says living room, with bathroom among the recommended uses. The spec table does not name a remote, and the plug standard is not printed, so a Schuko lead is an electrician job rather than a travel adaptor. The seller’s “up to 7 m²” is a line on the listing, not a promise for a poorly insulated room. Full power is about 9 p an hour at 26.32 p/kWh before the standing charge, and a thermostat spends less than that.
Pros
Cons
Best for: A small living room, bedroom or office where about 7 m² of seller coverage is honest and another heat source already exists
Less suitable: A larger wall, a bathroom you plan to plug into, or a buyer who needs a BS 1363 plug printed on the listing

Common questions
Does the listing claim bathroom use?
Recommended uses include bathroom, and a bullet claims IP44. The room type field says living room, and indoor/outdoor says indoor. The plug standard is not printed.
What area and what size does the listing print?
Heating coverage is printed as up to 7 m². Dimensions are 5 cm deep by 60 cm wide by 60 cm high, and a bullet also says 60 x 60 cm. Weight is 3.6 kg.
What controls are printed?
A bullet says the Klarstein app sets the temperature over Wi-Fi and that a thermostat is included. The spec table does not name a remote. Questions about offline use and app setup are unanswered in the file.
The Art2Heat listing at £128 is titled as a far-infrared heating picture in Mountain, but the spec table prints no wattage, voltage, coverage, thermostat or IP rating. The form factor is Tower and the dimensions are 58 cm by 9 cm by 9 cm, with a second bullet at 56 × 9 × 9 cm, so it is not the flat 5 cm wall panel the Klarstein files describe. A bullet says the product weighs under 1 kg while the spec-table weight is blank. The listing asks whether it can be wall-mounted and whether it has a timer, and stores no answer. There is no customer-review star line in the file. Claims of a 50-year life, better circulation and a 5–30% energy saving are listing copy, not measurements. Without watts you cannot compare an hour of heat with the 350 W, 500 W or 700 W panels.
Pros
Cons
Best for: Only a buyer who accepts an unrated tower-shaped listing and will not treat it as a sized wall panel
Less suitable: Anyone who needs a printed wattage, a flat panel size, or a review count before they pay
Specifications
Common questions
What power does the listing print?
No wattage, voltage or amperage is printed. The heating element line says graphene. Fuel type is electric.
Can it be wall-mounted?
The listing asks whether it can be wall-mounted and does not store an answer. Form factor is Tower. Dimensions are 58 cm by 9 cm by 9 cm, and a bullet also says 56 x 9 x 9 cm.
Does the file show a thermostat, timer or IP rating?
No. A timer is asked and not answered. There is no IP line, no plug standard and no customer-review star line.
Four amazon.co.uk listings are kept. The score uses whether the file is a printed picture panel with a wattage, the star line and review count, a thermostat in the bullets, the IP and plug lines, and the shelf price against a spec you can use. There is no lab test. Written reviews in the files are from Germany or the Netherlands, so they are not UK owner opinion. A file with no wattage cannot take the specification block. Weights sum to 100. The highest score is the top pick. Best value is a different listing: the lowest price among the panels that print watts, after the thin review sample is already in the score.
Printed picture and watts
30%The listing has to be a printed wall panel with a wattage, a size and a weight you can read. The 700 W file prints 120 × 60 cm and 7.1 kg. The 350 W file prints 60 × 60 cm and 3.6 kg. The 500 W file prints 80 × 60 cm and 4.8 kg. The Art2Heat file is a tower at 58 × 9 × 9 cm and prints no watts, so it cannot take this block.
Amazon evidence
25%Stars and the review count come from the amazon.co.uk file for that ASIN. The 700 W panel is 4.0 from 60 ratings. The 350 W panel is 3.6 from 6. The 500 W panel is 5.0 from 3. The Art2Heat file has no star line. Written reviews in the Klarstein files are marked Germany or the Netherlands, so they are not UK owner opinion.
Thermostat and app
15%A thermostat in the bullets scores. A remote the spec table does not name does not. The three Klarstein files claim a Wi-Fi app. The 500 W file asks about use without Wi-Fi and stores no answer. The Art2Heat file has no thermostat line and no stored answer on a timer.
IP mark and plug
15%An IP44 bullet is a splash claim, not a zone approval. None of the four files prints a BS 1363 plug. A bathroom room type with a blank plug standard loses points. The 500 W file also prints solar powered with no solar panel in the box.
Shelf price
15%Shelf price in GBP is read against a spec you can use. About £173.49 with 350 W printed is the value block. About £128 with no wattage is not. About £254.69 is the dearest of the three Klarstein files and does not win this block.
An infrared picture heater is a printed radiant panel you hang like a picture. The decision is the wattage for the room, then whether the listing agrees with itself: a real thermostat, a print that matches the photo, an IP mark you can tie to the mount, and a BS 1363 plug or a plan for an electrician. Seller square metres are a line. A star average on a handful of ratings is a thin sample. This is not a lab test.
An infrared picture heater is a mains electric radiant panel with a printed image. You hang it on the wall like a picture. It warms the people and the surfaces it faces. You can feel warm in front of the panel while the air stays cooler, and a cold room can still condense. Energy Saving Trust treats infrared as direct electric heat and says not to swap a whole-house gas system for it, because electricity costs about four times gas per unit of energy.
Up to 7 m² and about 10–15 m² are lines on the listings. Roughly 50–80 W/m² is a rule of thumb, not a British Standard. A poorly insulated room can fall short of the line.
IP44 is splash protection. Zone 1 needs fixed, permanently connected equipment at IPX4 that the maker allows there. Ordinary sockets stay at least 2.5 m from the zone 1 boundary. A Schuko lead is an electrician job.
Energy Saving Trust says not to swap whole-house gas for infrared. Electricity costs about four times gas per unit. Quote watts, hours and the 26.32 p/kWh unit rate. Lines about 98% or 50% less are not measurements.
Match watts to the room you sit in, then treat the seller’s square metres as a line on the listing. On these files the 350 W Blue Wave is listed up to 7 m², the 500 W Starry Night for 10 m², and the 700 W Blue Wave for about 10–15 m². Retailer guides of roughly 50–80 W/m² are a rule of thumb, not a British Standard, and they are not a promise for a poorly insulated room. The Art2Heat card prints no wattage, so it cannot be sized against those lines. The panels are about 5 cm deep.
A thermostat is the control that stops the panel sitting at full power. On the 350 W and 700 W Klarstein files a bullet claims a thermostat and a Wi-Fi app. The 500 W title and a bullet also name a thermostat. The spec table on all three does not name a remote. The 500 W file asks whether the heater works without Wi-Fi and stores no answer. If the app fails, you want a button on the panel. That button is not printed here. IP44 appears as a bullet on the three Klarstein files.
Three typical situations, each with a recommendation from this comparison.
You want a slim picture on a wall you sit facing, for about 7 m² of seller coverage, and the house already has heat. The Klarstein HTR10-WdwlS350W Wave is best value at about £173.49: 350 W, 60 × 60 cm, 3.6 kg. The star line is 3.6 from 6 ratings, and the plug standard is not printed.
You want the 120 cm print and the largest review sample in this set. The Klarstein 10035130 is the top pick at about £254.69: 700 W, listed for about 10–15 m², 7.1 kg, 4.0 from 60 ratings. Written reviews in the file are not from the UK. Plasterboard needs proper anchors.
You want the Starry Night print, listed for 10 m², and you will have an electrician check any bathroom plan. The Klarstein HTR10-WdwlS500wStarN is about £214.19, 500 W, 4.8 kg, with an IP44 bullet. The star line is 5.0 from 3 ratings. The plug is not printed, so the bathroom label is not a zone pass.
The top pick is the Klarstein 10035130 at about £254.69. It has the highest listing score in this set: 700 W on a 120 × 60 cm face, listed for about 10–15 m², with 4.0 from 60 ratings. Written reviews in the file are not from the UK, and 7.1 kg needs a proper fixing. Best value is the Klarstein HTR10-WdwlS350W Wave at about £173.49, 350 W, listed up to 7 m², the lowest price among the listings that print watts. Skip the 700 W panel if the 60 cm print already covers the wall. Skip the 350 W panel if you need the larger face. Skip the Art2Heat card if you need a printed wattage.
