Infrared heater buying guide

Updated: October 2026

A 50 W damp-wall plate, a white indoor panel, a 1,000 W floor tower and a 2,000 W patio bar all appear when you search infrared heaters on amazon.co.uk. This infrared heater buying guide puts the job first, then the watts and the IP mark, and only then the stars. The twelve listings are on the [Steinfeld infrared heater comparison](/hub/heating/steinfeld-infrared-heater). The Products Compared editorial team checked those files on 15 October 2026. None of these heaters is a Steinfeld model, and this is not a laboratory test. A qualifying purchase can earn us a commission at no extra cost to you.

Four heaters, not one

The Könighaus 450 W, 600 W and 800 W units are flat white indoor panels. The Warmlite WL42013 is the freestanding tower, 500 W or 1,000 W. The INGRIKT is a 50 W damp-wall panel. The other listings are outdoor radiant heaters. A 450 W panel will not do a 2,000 W bar’s job over a gazebo seat. Energy Saving Trust puts home panels at usually 350–900 W. Who each pick is for is on the best infrared heater page.

Watts before stars

The Könighaus 600 W file claims roughly 8–16 m² and includes no thermostat. A Devola bullet claims rooms up to 20 m² while its table says 1,200 W. The Könighaus 450 W is £99.90, 3.8 stars from 582 reviews, and the comments limit it to a small, well-insulated space or heat on the person. The 800 W model is £169.90, but one bullet still says 450 W. The 50 W INGRIKT is a damp patch, not room heat.

Thermostat, app, or just a dial

The Könighaus 600 W is wall only, with no thermostat and no remote in the box, at £121.90 and 4.0 stars from 23 reviews. The 450 W and 800 W claim Wi-Fi, a remote, a towel rail, feet and IP44. The Harrier has three heat levels and no timer. The freestanding SOUTHEATIC has eight levels, an eight-hour timer and no remote battery in the box. A remote with no cell is on the how to use an infrared heater page.

IP rating and where it will live

IP44 is claimed on the Könighaus 450 W, the 800 W and the INGRIKT, and none names a bathroom zone. The 600 W mentions a bathroom and prints no IP rating. Infrared Heaters Direct points outdoor buyers to at least IPX4. The Harrier states IPX4. The Pro Breeze and the SOUTHEATIC bars state IP65. The Devola DVPH2000B title says 2,000 W and IP65, and the table says 1,200 W and IP24. The DVPH2400B title and table also disagree on watts. Zones are on the infrared heater bathroom page.

A short check order

Name the job: heat on a person indoors, a damp patch, or a seat outside. Read the watts in the title and the details table. See whether a thermostat, an app or only a remote is in the box. Read the IP line, and do not install from a title that fights its table. The 3,000 W SOUTHEATIC is 4.7 from only 11 reviews.

Common questions

Is 450 W or 800 W enough for a living room?
Energy Saving Trust puts ordinary home panels at about 350–900 W and says some rooms need more than one. The Könighaus 450 W reviews describe a small, well-insulated space or heat on the person, not a living room full of people. The 800 W listing is 90 cm square, but one bullet still says 450 W, and the file holds only five written reviews.
Which IP rating matters indoors, in a bathroom, and outside?
Away from splashes, the Warmlite tower prints no IP rating and is sold as an indoor floor heater. For bathroom zones, Herschel’s splash FAQ and retailer guides talk about IP44 or IPX4 as a minimum outside the bath itself, and the distances are on the bathroom page. Outside, Infrared Heaters Direct points buyers to at least IPX4. The Harrier states IPX4, and several bars state IP65. The Devola DVPH2000B states both IP65 and IP24, so you cannot pick the number from the title alone.
Why do two Devola listings disagree with their own details tables?
The DVPH2400B title says 2,400 W and the table says 1,200 W, while the file also lists 10 A at 240 V, which multiplies to about 2,400 W. The DVPH2000B title says 2,000 W, IP65 and indoor and outdoor use, and the table says 1,200 W, IP24 and indoor. Buy either listing only if you can confirm the plate on the unit. Do not choose a bathroom or a rainy patio from the title.
Is a 50 W panel a room heater?
No. The INGRIKT listing is sold for damp walls and condensation, at £39.99, with IP44 claimed and only 15 reviews. One of six written reviews recorded about a 3°C rise in a mouldy corner and about 78°C on the surface. That note is not a mould treatment and not room heat. If you wanted a 450 W panel for a home office, this is the wrong object.
Can I trust a seller’s square-metre claim?
Treat it as the seller’s claim. The Könighaus 600 W file talks about roughly 8–16 m², and a Devola bullet says up to 20 m². Surya’s chart of 25–35 W per cubic metre is a seller chart, and other retailers use different sums. The Warmlite file prints coverage as 270 with no unit. Energy Saving Trust’s 350–900 W band is the public figure to start from.
