600W infrared panel heater buying guide

Updated: 22 October 2026

You already know the wattage. The open question is whether 600 W, the control in the box, and the plug match the room you actually have. The five amazon.co.uk listings in our [600W infrared panel heater comparison](/hub/heating/600w-infrared-panel-heater) do not agree on square metres, and two of them tell you to add a thermostat rather than include one. Prices in that set run from £89.99 to £149.90 on the extracts from 19 October 2026. None of those pages prints the words BS 1363. Peter F. compared the listings on 20 October 2026. Nothing was tested in a lab. A qualifying purchase can earn a commission at no extra cost to you.

What 600 W can and cannot heat

600 W is 0.6 kW of direct electric heat. Energy Saving Trust treats it like other electric room heaters: about one unit of heat per unit of electricity. A seller rule of thumb, not a British Standard, puts a well insulated 2.4 m room at about 60–80 W per square metre, so 600 W is roughly 7.5 to 10 m². Herschel’s 600 W panels, outside this set, print about 11–13 m². The basic Hocosyme prints 6–12 m² and 8–15 m². The remote Hocosyme prints 6–12 m². The P-600 prints about 8–16 m² and says insulation and ceiling height change the result. The KAISER and the Smart Dual print no square metres. Pence are on the running cost page.

Thermostat in the box or an extra you must buy

A 600 W panel with no thermostat stays at 600 W until you switch it off. Overheat protection is a cut-out, not a set point. The P-600 says the thermostat is not included. The basic Hocosyme at £89.99 only recommends one. The £109.99 Hocosyme describes a remote to 10 m and timed on and off. The KAISER at £114.95 prints an LCD and a remote. The Smart Dual at £149.90 prints Wi-Fi and a weekly schedule, with feet and a towel rail. The P-600 is £121.90 and still withholds the thermostat. Which listing to open first is on the best 600W infrared panel heater page.

Wall, feet, ceiling, and weight

Both Hocosyme models are 5 kg wall kits with a 1.8 m cable. One UK review treated feet on the basic model as an extra of about £29. The P-600 bullets say wall only, at 11 kg, while the form-factor field says Tower. Trust the wall-only bullets unless a live photo shows feet. The Smart Dual adds included feet and a towel rail, at 7 kg. Only the KAISER prints wall, ceiling, or stand feet. The Hocosyme panels claim up to 120 °C, so keep the face clear of curtains. A new ceiling cable is electrician work. If the room is a bathroom, the bathroom zones page comes before feet or a towel rail.

Plug, voltage, and claims to skip

UK mains are nominally 230 V. Regulation 35 requires a BS 1363 plug for this domestic use, and none of the five extracts prints that phrase. The P-600 and the Smart Dual print 230 V. The Smart Dual and the KAISER print 2.61 A. The KAISER file has no UK review, and the non-UK comments disagree about the plug. If the pins are round, return it. Do not rewire the lead. Energy saving, a 98% line, graphene, or a bacteria claim does not change the 600 W nameplate. A TÜV or GS mark on the page is not a UK room-size certificate.

Common questions

Is 600 W enough for a bedroom?
A small, well insulated bedroom with a ceiling around 2.4 m often sits inside a seller guide of about 60–80 W per square metre. That is not a test of your room. The basic Hocosyme prints both 6–12 m² and 8–15 m², and the P-600 prints about 8–16 m² with an insulation caveat. A large or leaky bedroom can fall outside the smaller number.
Why do two listings give different square metres for the same wattage?
The wattage is the same. Insulation, ceiling height, and the temperature you want all move the result, which is why the P-600 prints a range and then says it may vary. The basic Hocosyme prints two ranges on one listing, 6–12 m² and 8–15 m². Show them side by side. The Smart Dual and the KAISER print no square metres. A missing figure is not a promise of 16 m².
Does the panel include a thermostat?
Only if the bullets say so. The P-600 says the thermostat is not included. The basic Hocosyme recommends one and does not describe one in the box. The £109.99 Hocosyme prints a remote and timed on and off. The KAISER prints an LCD thermostat and a remote. The Smart Dual prints Wi-Fi, a remote, and a weekly schedule. A question on the page is not the same as a yes.
Should I buy wall-only, feet, or ceiling mounting?
Buy the mount you can actually fix. Both Hocosyme models and the P-600 are wall kits in the bullets, and the P-600 is listed at 11 kg. The Smart Dual adds feet and a towel rail. Only the KAISER prints wall, ceiling, or feet. One review of the basic Hocosyme treated feet as an extra of about £29. A ceiling claim can mean an electrician rather than a plug into an existing socket.
How do I know the plug is a UK plug?
Look at the pins on the amazon.co.uk photos and in the box. Regulation 35 requires a BS 1363 plug, and none of these five extracts prints that phrase. The P-600 and the Smart Dual print 230 V. The KAISER plug is unproven, because there is no UK review and the non-UK comments conflict. Do not rewire a continental lead yourself.
When is 600 W the wrong class?
When the smaller coverage figure is already below the floor area, or the room is tall, leaky, or meant to heat like a whole-house radiator circuit. A home office with one person in line of sight is a fair 600 W job if the control is sorted. A large through-lounge, or a house you hoped to take off the boiler, is a higher wattage or the heating you already have.
