The best Klarstein heaters, compared.
Top pick: Klarstein picture panel 500 W – Highest star line in this set, 4.5 from 12 ratings, at about £168.29, with IP44 stated. The sample is thin, and 500 W is top-up heat. Best value: Klarstein Bansin Smart 2500 W – About £209.19, under the 1500 W Bansin, with more watts, wheels and a wall kit named. No IP rating is stated, and full output costs more to run. Updated October 2026.
A Klarstein heater is one of four electric room heaters captured on amazon.co.uk: two convectors and two wall infrared picture panels. You use them as a top-up for one room, not as a replacement for a boiler. Separate them by watts, by warm air versus a picture surface, by whether the listing states an IP rating, and by whether they stand on feet. That is the highest star line here, and the sample is thin. It undercuts the 1500 W white, states more watts, and names wheels and a wall kit. The 2500 W capture states no IP rating. Saved review texts are not tagged as written in the United Kingdom. Choose the heat method before the wattage in the [Klarstein heater buying guide](/hub/heating/klarstein-heater/sub/klarstein-heater-buying-guide). The picture panels are radiant and need a line of sight. Convectors beyond this Klarstein set are in the [convector comparison](/hub/heating/convector).

Personal buying guide
Question 1 of 2
How should it heat the room?
Klarstein’s 500 W mountain picture panel at £168.29 is an 80 cm by 60 cm wall heater, 5 cm deep and 4.8 kg, drawing 2.27 A at 220 V with a 37 °C maximum on the attribute table. Amazon.co.uk shows 4.5 from 12 ratings, the highest average in this set, though the seven saved review texts are tagged the Netherlands, Germany or France, not the United Kingdom. Bullets claim IP44, a Wi-Fi app, an electronic thermostat and a remote, plus 16.3 m² coverage, and the room-type line says bathroom. Reviewers praise light mounting and useful top-up heat in small rooms, including one 8 m² bathroom, and one office user liked the app schedule. One buyer returned the panel because about 20 cm of side clearance would not fit beside a cupboard, a distance the attribute table does not print. A repeat order arrived scratched and not heating on the first delivery. Full output is about 13 pence an hour at the Ofgem Direct Debit average of 26.32 p/kWh for 1 October to 31 December 2026, before the thermostat cycles. Treat 500 W as supplementary heat on a wall you have measured, not as the only heat in a cold box room.
Pros
Cons
Best for: A small home office or ensuite wall where 500 W of top-up heat and the mountain print fit, and the room already has another heat source
Less suitable: A medium living room as the only heat, a tight cupboard wall you have not measured, or a buyer who needs a large sample of UK-written reviews
Specifications
Common questions
Can this panel be used outdoors?
The attribute table says indoor. The listing question about outdoor use is not answered with an outdoor rating.
What IP rating does the listing state?
The bullets state IP44 and include bathroom wording. Clearance distances are not in the attribute table. One non-UK review mentioned about 20 cm.
Where do the written reviews come from?
The star line is 4.5 from 12 ratings on the amazon.co.uk capture. The seven review texts are tagged the Netherlands, Germany, or France.
The white Bansin Smart at £225.39 is a 1500 W convector, 68 cm wide, 52 cm high and 26 cm deep, weighing 6.4 kg, with two castor feet and a wall kit in the box. Amazon.co.uk shows 4.3 from 41 ratings; the 12 saved review texts are tagged Germany, not the United Kingdom. Bullets state IP24 splash protection, a 5–50 °C thermostat, two speeds and the Klarstein Experience app, and they name the kitchen and the bathroom. Reviewers often say the heat is enough and the controls are simple, though one buyer planned to step up to a larger model next time. A loud click when the thermostat cuts out comes up more than once, and one buyer found the timer counted hours rather than a clock time. Wi-Fi login failed for one person, who then ran it from the panel, and another box arrived with no remote. Full output is about 39 pence an hour at 26.32 p/kWh before the thermostat cycles. You pay more than for the 2500 W black Bansin to get a stated IP24 line and a 6.82 A draw, not to get more heat.
Pros
Cons
Best for: A kitchen or a dry room beside a wet area where you want convection, feet, and an IP24 claim you can check against the install
Less suitable: A bedroom that cannot tolerate a relay click, a buyer who needs a clock-time timer, or a bathroom treated as a portable plug-in without a zone check
Specifications
Common questions
Does this listing state a bathroom IP rating?
The bullets state IP24 and name the kitchen and the bathroom. The attribute room type is bathroom. That is a listing claim, not a zone plan for your room.
Does the capture confirm open-window detection?
The listing asks the question. The bullets do not confirm open-window detection, so the field is n/a
Where do the written reviews come from?
The star line is 4.3 from 41 ratings on the amazon.co.uk capture. The 12 review texts in the saved listing are tagged Germany, not the United Kingdom.
The 700 W Blue Wave picture panel at £254.69 is the widest face in this set at 120 cm by 60 cm, still 5 cm deep and 7.1 kg, drawing 3.18 A at 220 V with a 37 °C maximum. Amazon.co.uk lists 4.0 from 60 ratings, and the 22 saved texts are tagged Germany or the Netherlands. Bullets claim IP44 and wet-room wording with about 10–15 m² coverage, while the attribute room type says living room. Some buyers describe pleasant shoulder-season warmth and straightforward mounting, including on a thin wall and in a plasterboard room that had no radiator. Others say the print arrived a frog green rather than the turquoise in the photos, the picture surface looked thin or bowed, and the app crashed or lost control after an update. One account has the panel showing 37 °C and switching off while an 8 m² bathroom stayed near 20–21 °C, and the manual switch lamp is called too bright for a bedroom. Full power is about 18 pence an hour at 26.32 p/kWh before cycling. You pay the most here for a wide print and the largest review sample, not for guaranteed whole-room comfort.
Pros
Cons
Best for: A dry living room or hallway wall where the wide print is part of the décor and you can live with app-led control
Less suitable: A buyer who needs the print to match the listing photos, a dark bedroom, or fast warm-up as the only heat in a cold room
Specifications
Common questions
Does the listing name a third-party smart-home system?
The bullets name the Klarstein app over Wi-Fi. They do not name Alexa, Google, or another platform for this ASIN.
What temperature ceiling is printed?
The attribute table prints a maximum temperature setting of 37 °C. One non-UK review describes cut-out at that reading while the room was still about 20–21 °C.
Where do the written reviews come from?
The star line is 4.0 from 60 ratings on the amazon.co.uk capture. The 22 review texts in the saved listing are tagged Germany or the Netherlands.
The black Bansin Smart at £209.19 is a 2500 W convector, 100.8 cm wide and 8.4 kg, with wheels, a wall kit and a remote named in the bullets. It lists 11.36 A at 220 V on a 1.5 m cable and a 5–50 °C thermostat, and the title claims up to 50 m². Amazon.co.uk averages 3.9 from 37 ratings, the lowest star line here; the 11 saved texts are tagged Germany or Spain. Reviewers praise a fast warm-up and the choice to stand the heater or hang it, and one person later controlled it from another room after pairing. Wi-Fi failed on a Telekom Speedport after the stated router steps, seller replies were slow, and one unit arrived with loose internal parts and was never used. This capture states no IP rating, and the room-type line is bedroom and living room, so you cannot copy splash protection from the white 1500 W Bansin. Full output is about 66 pence an hour at 26.32 p/kWh, so the lower shelf price is not a lower bill if you hold full power. It is the most watts for the money in this foursome when you will use the on-unit controls if the app drops, and you keep it out of splash.
Pros
Cons
Best for: A large living room or open-plan space where you want convection on wheels and will use the heater’s own controls if pairing fails
Less suitable: A bathroom or any splash-adjacent install, and any buyer who reads the lower shelf price as a lower running cost
Specifications
Common questions
Is an IP rating printed for this 2500 W model?
No. The raw capture does not state IP24 or any other IP code. The room-type line is bedroom and living room.
What protection does the listing actually name?
The bullets name overheating protection and an automatic switch-off. They do not name a child lock or a tip-over switch.
Where do the written reviews come from?
The star line is 3.9 from 37 ratings on the amazon.co.uk capture. The 11 review texts in the saved listing are tagged Germany or Spain, not the United Kingdom.
Four Klarstein electric heaters were taken from amazon.co.uk on 20 October 2026. There is no lab test. The row score is the amazon.co.uk star rating divided by five, then multiplied by 100. A 4.5 becomes 90 on that scale, shown here as 9.0 out of 10. Review count, price, IP rating and the fact that saved review texts are not tagged United Kingdom sit beside the score and do not change it. The top pick is the highest score, the 500 W picture panel, and the sample is 12 ratings. Best value is the 2500 W black Bansin because the shelf price undercuts the 1500 W unit and the listing states more watts, with wheels and a wall kit. The lower shelf price is not a lower running cost at full output. The weights below are the buying checks used to read the table. They are not a second score.
Heat method
25%Convectors move warm air. Picture panels are radiant and need a line of sight. The method comes before the wattage.
Watts and claimed area
20%A rule of thumb is about 100 W per square metre in an older room. Coverage lines such as 50 m² or 16.3 m² are listing claims, not a tested result.
IP rating and place
20%Only an IP code printed on that listing counts. IP24 is on the 1500 W Bansin. IP44 is on both picture panels. The 2500 W file has none.
Plug, voltage and current
15%No capture names the plug. The tables say 220 V. UK mains are nominally 230 V, and a domestic socket expects a BS 1363 plug.
Controls and review origin
10%Timers and an app are claimed on all four. Saved review texts are not tagged United Kingdom, and two listings do not guarantee an English manual.
Shelf price and running cost
10%The 2500 W unit costs less to buy than the 1500 W unit. Running cost follows hours and the unit rate, not the shelf price.
A Klarstein heater on this page is either a Bansin convector or a wall picture panel. Decide the heat method, then the watts, the IP line on that listing, and whether you can drill. A star line is the amazon.co.uk average on 20 October 2026, not a lab score. Saved review texts are not tagged United Kingdom. A coverage claim is not a measured room size.
A Klarstein heater here is one of four Klarstein electric room heaters captured on amazon.co.uk on 20 October 2026. Two are Bansin Smart convectors. Two are wall infrared picture panels. You use them as a top-up for one room, not as a boiler replacement. The Bansin units move warm air. The picture panels are radiant and need a line of sight. Pick the method before the wattage. Convectors beyond this Klarstein set are in the [convector comparison](/hub/heating/convector).
Up to 50 m² on the 2500 W Bansin, and 16.3 m² on the 500 W panel, are listing claims. A rule of thumb is about 100 W per square metre in an older room, so 500 W is a top-up.
IP24 is stated only on the white 1500 W Bansin. The 2500 W capture has no IP rating. The room-type line is bedroom and living room. Do not treat the lower shelf price as splash protection.
An app is claimed on all four. Reviews that are not tagged United Kingdom describe pairing trouble. Two listings do not guarantee an English manual. Read the plate for 230 V and a BS 1363 plug. No capture names the plug.
Start with the job. A Bansin convector moves warm air and can stand on feet or wheels, so a renter who must not drill stays with those two. A picture panel is radiant, wall-only, and needs a line of sight. The 500 W panel claims 16.3 m² and the 700 W panel claims about 10–15 m². The 1500 W Bansin claims up to 30 m² and the 2500 W Bansin claims up to 50 m². About 100 W per square metre is a rule of thumb for an older room, not a test of these four. Water is a separate check on each listing.
No capture names the plug. Regulation 35 of the Electrical Equipment (Safety) Regulations 2016 expects a BS 1363 plug for a UK socket. Every table here says 220 V. UK mains are nominally 230 V, so read the plate. The 2500 W Bansin lists 11.36 A at 220 V. The 1500 W lists 6.82 A, the 700 W panel 3.18 A and the 500 W panel 2.27 A. Timers and an app are claimed on all four. The 1500 W unit names the Klarstein Experience app.
Three typical situations, each with a recommendation from this comparison.
You want top-up heat for one room and you will check the plug, the thermostat range and the watts. The 500 W mountain picture panel at about £168.29 shows 4.5 from 12 ratings, with IP44 stated and a 37 °C maximum. Twelve ratings is a thin sample, and 500 W does not replace a boiler.
You need a stated IP rating, and an electrician if the heater sits inside a bathroom zone. Do not start from the 2500 W file, which states no IP rating. The white 1500 W Bansin at about £225.39 states IP24 and names the bathroom. That line is not permission for zone 0 or for a portable heater beside the bath.
You need feet or wheels and you must not drill. That is a Bansin convector, not a picture panel. The black 2500 W Bansin at about £209.19 names wheels and a wall kit, with 3.9 from 37 ratings. The room-type line is bedroom and living room. This capture states no IP rating.
These four Klarstein heaters are a one-room top-up, not a boiler. The top pick is the 500 W mountain picture panel at about £168.29, on 4.5 from 12 ratings, with IP44 stated. The sample is thin, and 500 W is supplementary heat on a wall you have measured. Best value is the 2500 W black Bansin at about £209.19, because it undercuts the 1500 W unit and states more watts, with wheels and a wall kit. It has the lowest star line here, 3.9 from 37 ratings, and no IP rating in the capture. The lower shelf price is not a lower running cost at full output.
