Best Infrared Heaters for Open Rooms

We've been using radiant infrared heaters in open-plan living rooms, high-ceilinged kitchens and chilly home offices to find out which ones actually take the chill off a cold corner — and which feel genuinely comfortable to sit near for hours. Our editors are running those hands-on evaluations now. Drop your email below to be notified the moment our verdict lands.

Does your open-plan living room have a cold corner that no heater seems to reach? Or a dining area where the warmth from the kitchen never quite makes it to the table?

Are you tired of fan heaters that push hot air around without making anyone actually comfortable — and rack up electricity costs doing it?

Infrared heaters work differently: they warm you and the objects around you directly, the way sunlight does. That makes them especially well-suited to open rooms where heating the air alone is a losing battle. We're currently living with the top five models on the market — running them in our own homes, in real rooms, over days and weeks — to find out which one we'd plug in again.

We're currently testing the top 5 Infrared Heaters on the market.

Our editors are living with each unit in real open-plan rooms — running them through cold mornings, long evening sessions and overnight use — comparing how quickly each one takes the chill off and how comfortable it feels to sit near for hours. We read every owner review we can find and compare notes before we publish a word.

What we evaluate

  • Speed to warmth — how quickly you actually feel the heat from cold start, and whether it reaches across an open room to where you're sitting
  • Comfort over hours — whether the radiant warmth feels pleasant to sit near for a long evening, or becomes too intense, too directional or too uneven
  • Running cost & wattage settings — how efficiently each unit heats a real open space, and whether lower-wattage modes are genuinely usable
  • Safety & build quality — surface temperatures, tip-over protection, overheat shutoff and how well the unit is built for everyday home use

Frequently Asked Questions

What makes infrared heaters good for open-plan rooms?
Infrared heaters warm people and objects directly rather than heating the air, which means they feel effective even in open rooms where warm air would quickly disperse. You feel the warmth within seconds of switching one on, and it stays comfortable even with high ceilings or a drafty layout — which is exactly why we focus on this type for open-plan homes.
Are infrared heaters expensive to run?
Infrared heaters are generally efficient because they warm you directly rather than wasting energy heating a large volume of air. A 1,500W infrared unit costs roughly the same to run as any other 1,500W heater, but because the warmth feels more immediate, many people find they're comfortable at a lower wattage setting — which can mean lower bills in practice. We track real-world running feel across all five units in our review.
Is it safe to sit near an infrared heater for long periods?
Yes, for most people. The radiant warmth from a domestic infrared heater is similar in character to gentle sunlight — pleasant and comfortable to sit near for hours. You should keep the unit clear of curtains and soft furnishings, and avoid placing it where children or pets could touch the heating element directly. Always follow the manufacturer's safety guidance, and we note comfort and surface heat in every review we publish.
How far does an infrared heater's warmth reach in an open room?
That varies by wattage and the specific unit, but most 1,000–1,500W infrared heaters are rated by their makers to cover 150–300 square feet of effective warmth. In a truly open-plan room, you're better off positioning the heater to face the seating area directly rather than expecting it to heat the whole space — and we test each unit exactly that way in our reviews.
Do infrared heaters work without a fan, and are they quiet?
Many infrared heaters have no fan at all — they radiate heat silently, making them a good choice for living rooms and home offices where fan noise would be distracting. Some models add a fan to help distribute warmth faster; those will produce a low hum. We note fan presence and noise character in every review we publish, because quiet matters when you're sitting near a heater for an entire evening.
