The small-room pick in this set
For a small occupied spot with feet, a remote and Wi-Fi already in the carton, the 450 W Smart Dual is the pick here. It lists at about £99.90, with 3.8 out of 5 from 582 reviews, the largest sample in the set. The carton includes stand feet, a wall kit, a remote, Wi-Fi scheduling and a towel rail. The listing prints IP44. The maximum temperature setting on the spec table is 40 °C.
A UK review dated 3 December 2025 describes heat within a couple of minutes for a smaller area and warns against large rooms. That fits a desk or one floor, not open-plan comfort. Read 3.8 as a mixed line, not as proof it will heat a flat.
Reviewers call the face and the back too hot to touch. Some distrust the app figure against the room. One delivery arrived without instructions, feet and the remote, so check the box before you bin the packaging. Watt order for other rooms is on the buying guide.
Who should buy the P-600 instead
Choose the P-600 if you will wall-mount, add a thermostat, and you want a printed coverage band more than feet and an app. It lists at about £121.90 with 4.0 from 23 reviews, a higher average on a much thinner sample than 582. The bullets claim about 8–16 m². The spec line prints 16 m². Older titles sometimes said “up to 13 m²”. That spread is not a guarantee for a cold extension.
The box is fixings and a 1.80 m cable. No feet, no remote, no Wi-Fi. One reviewer bought feet separately. A renter who cannot drill is on the wrong row. A 4.0 from 23 reviews does not beat 3.8 from 582 by itself. The carton split is on Könighaus Smart Dual vs P-series.
Why the larger Smart Dual is not the upgrade
The 600 W Smart Dual at about £149.90 and the 800 W at about £169.90 buy more watts and a larger face. Neither listing prints square metres. Both still tell you, in a bullet, to mount the 450 W panel while the spec table lists 600 W or 800 W. The product data share one image URL between those ASINs, so read the live spec table before you assume size.
The 600 W row is 4.2 from 205 reviews, the top pick on star average. For a desk-sized spot, more watts can mean a hotter surface and a larger panel. One 800 W review said the unit felt large for a small room. Move up only when 450 W is already at the edge of what reviewers describe.
Who should skip the whole set
Skip these five listings for a large open-plan room on one panel, for replacing gas central heating, or for bathroom zone 1 or 2 with a plug-in panel and no electrician. The Energy Saving Trust says electricity is a poor swap for gas at that scale. BS 7671 wet zones expect fixed, permanently connected equipment of at least IPX4.
Skip the P-series if you will not drill and will not buy a thermostat. Skip the 600 W or 800 W Smart Dual if you treat the copied 450 W bullet as the wattage.
Common questions
Which one panel is the small-room pick in this set?
The 450 W Smart Dual at about £99.90, for a small occupied spot with feet and an app in the box. The amazon.co.uk line is 3.8 from 582 reviews. The listing does not print square metres. Reviewers describe a desk or one floor.
Who should buy the P-600 instead?
Someone who will wall-mount, buy a thermostat, and wants the about 8–16 m² claim more than bundled Wi-Fi. The carton is fixings and a 1.80 m cable. It does not include feet. A renter who cannot drill should stay with the Smart Dual that stands on the parts supplied.
Why not the 800 W Smart Dual if it has more watts?
More watts here do not come with a printed square-metre range. The 800 W Smart Dual lists at about £169.90, and one review said the panel felt large for a small room even at that output. The spec table still sits beside a bullet that mentions the 450 W panel.
Is 3.8 from 582 a test win?
No. It is the amazon.co.uk star line on the 450 W listing, not a UK comparative test. The main comparison’s top pick is the 600 W Smart Dual at 4.2 from 205, from stars divided by five. For a small spot, the larger sample and the lower price point the other way.
What did UK reviewers say the 450 W cannot do?
Heat large or open-plan rooms comfortably. Several frame it as a smaller-area heater, useful under a desk or on one floor, with warmth close to the panel. The surface is also described as too hot to touch, including the back.
Does the P-600’s 4.0 from 23 beat the 450 W?
Not automatically. Twenty-three reviews are not a bigger sample than 582, even though the average is higher. Use the P-600 when you want a wall panel and a printed range, and you will add a thermostat.
When is the honest answer none of these?
When you need whole-house heat, a ceiling mount, or wet-zone wiring without a competent installer. The P-series FAQ forbids ceiling mounting. Bathroom zones expect fixed equipment, not a plug-in panel on feet.
