In our review of the best infrared heater options for 2026, Opranic THOR S70, PRO V70 and NOVA V50 stand out: complete redesigns of award-winning product lines recognised by Aftonbladet, The Independent, The Telegraph, Inspekto, Testson, Testat.nu and Hantverksproffset, alongside hundreds of positive reviews on Amazon across Europe.
Which patio heater comes out on top in 2026? The market is crowded, and it can be difficult to see past the marketing claims. But the underlying question is straightforward.
For a broader look at what to consider before buying, see our complete outdoor infrared heater buying guide.
A patio heater has one job: to deliver warmth to people, not to the air, not to the surroundings, but to whoever is sitting on the patio, balcony or terrace. The heater that converts the highest share of every input watt into infrared warmth the body actually absorbs is simply doing a better job than one that does not.
In this review, we explain what determines heating performance, how Opranic engineers its products to maximise it, and what the THOR S70 and PRO V70 mean in practice for you as a user.
Anyone comparing the best infrared heater models for 2026 will find that the differences between individual units often come down to how efficiently the heat is converted and directed towards the body.
Best infrared heater 2026: why Opranic delivers more heating performance per watt
Most brands on the Swedish market buy in ready-made infrared heaters from a manufacturer, add their own logo, and market the product through their own channels. It is a common business model, and it produces functioning products, but it means the brand has no control over how the heater performs on the inside.
They cannot choose the wavelength, optimise the reflector, or test and adjust the components until the highest possible heating performance is reached. They get what they get, and that is an important factor for anyone searching for the <strong>best infrared heater</strong> in 2026.
Opranic works differently. The company designs and engineers its infrared heaters from the ground up. Every component is selected to deliver a specific outcome: the highest possible heating performance per watt consumed, combined with a long lifetime in Scandinavian outdoor conditions.
The heating element is a carbon element from Japan with documented high performance. The reflector is engineered to spread radiation broadly and direct it towards the seating area. The body is built from solid aluminium with a stainless steel grille, designed to withstand years of outdoor use without material degradation. The electronics control five power levels, a remote control, and a 9-hour timer that switches the heater off automatically.
No single component makes Opranic distinctive. It is how every part works together.
A high-performance carbon element combined with an optimised reflector, a robust housing, and well-considered electronics produces a heater that delivers more usable warmth for every kilowatt-hour consumed than a product whose components were never designed to work as a system.
Behind this lies more than 20 years of experience in outdoor heating on the Scandinavian market: a long development curve built on direct contact with both professional users and consumers. Opranic understands the demands placed on a product used outdoors in a Nordic climate, season after season, without any drop in performance or durability.
Add to this the Scandinavian design philosophy. Opranic is a Swedish company, and its products are shaped to suit Scandinavian homes and outdoor spaces. An infrared heater from Opranic is not simply an appliance. It is an object of design that adds visual value to your patio.
The heating technology: why it feels like sunshine
What determines how effective an infrared heater is comes down, ultimately, to physics. When the sun warms you on a cold winter’s day, it is not because the air is warm. The air temperature can be well below freezing. But the sun’s infrared rays reach your skin directly, and your body absorbs that radiation and converts it into warmth. That is why you feel heat on your face even though the air around you is cold.
A patio heater works on the same principle. But how effectively it performs depends on the wavelength of the radiation it emits. The human body is roughly 80% water, and water absorbs infrared radiation most efficiently at a wavelength around 2.4 µm. That happens to be exactly the wavelength Opranic’s IR-X Carbon Black technology is engineered to emit, and one of the reasons earlier Opranic models have repeatedly ranked among the best infrared heater results in independent tests over the years.
Run any proper infrared heater test in 2026 and the difference between models quickly becomes clear: it comes down to how precisely the heat is directed at the body and how much usable warmth you get per watt.
The result: 96% of the electrical energy supplied is converted directly into radiant heat. The small remainder that becomes visible light is a soft, gentle glow. You feel the warmth immediately, with a start-up time of just 3 to 5 seconds.

Awards and Recognition
Earlier Opranic models have, over the years, repeatedly ranked highly in independent reviews and received a number of awards, both in Sweden and internationally. Publications that have recognised previous product lines include Aftonbladet, Inspekto.se, Testson.se, Testat.nu, Hantverksproffset.se, The Independent and The Telegraph. The products have also collected hundreds of positive reviews on Amazon across Europe, a combined confirmation that heating performance, build quality and user experience meet the standard Opranic sets out to achieve.
A German customer with a 45 m² conservatory had previously tried both an infrared heater with no visible glow (often called a “dark heat infrared heater”) and a halogen heater before choosing the PRO V70R. After a careful evaluation, he settled on Opranic. He particularly highlights that the warmth feels like direct sunlight on the skin, that the carbon infrared technology delivers instant heat with no warm-up time, and that both the design and the build quality are noticeably ahead of the competition.
“I’m sitting on the patio right now writing this review. The right choice, I can recommend Opranic 100%.”

The new THOR S70, PRO V70 and NOVA V50 are complete redesigns of the product lines behind these awards. New tooling, new housing, new technology. Everything that made the award-winning models what they were remains intact, but improved on every point: higher power, more heat settings, longer lifetime, a higher IP rating, a timer, and a three-year warranty.
Opranic THOR S70: portable patio heater for terraces, balconies and conservatories
THOR S70 is the freestanding model. An all-metal construction in powder-coated aluminium with a brushed stainless steel grille. It stands 106 cm tall and weighs 8.1 kg. Position it beside the dinner table on your patio, move it to the balcony the next day, and bring it into the conservatory as autumn sets in. Radiant heat for balcony, patio or terrace, wherever you need it, whenever you need it.
The IP65 rating means the heater is fully dust-protected and withstands heavy rain, so you can leave it outdoors year-round. The remote control adjusts power level and sets the built-in 9-hour timer. Safety is managed by overheat protection and an electronic tilt switch that shuts the heater off immediately if it tips over.

Opranic PRO V70: wall-mounted heater for walls, ceilings and outdoor dining areas
PRO V70 uses the same technology and delivers the same performance as THOR S70, but is engineered for permanent installation on a wall, ceiling, or beneath an awning. The body is made from anodised aluminium with carbon-fibre-reinforced side panels and a brushed stainless steel grille. The design is slim and elongated, sitting quietly within its surroundings as part of the architecture rather than an addition to it.
For restaurants and hospitality patio heater applications, PRO V70 is the natural choice. Five units mounted at three-metre intervals cover a 60 square metre outdoor dining area. For home use, PRO V70 works equally well mounted beneath an awning, on a patio wall, or in the ceiling above an outdoor table.

Operating cost
With Swedish electricity prices at roughly 2 to 2.50 kronor per kilowatt-hour, including grid fees and tax, running the THOR S70 or PRO V70 at full power costs 5.75 kronor per hour. At level 3, which is enough for most evenings, the cost drops to around 4 kronor per hour.
A full season from April to September, with 300 hours of outdoor evenings on the patio, balcony, or in the conservatory, costs around 1,200 kronor in total, roughly 200 kronor a month.
Operating cost: electricity compared with gas
1× PRO V70R electric (2.3 kW)
1× Gas patio heater (~12 kW)
A 60 m² restaurant terrace needs 5× PRO V70R units mounted every 3 metres, for a total of around 14 kr/h in Sweden. A single gas patio heater covers 10–15 m² at 9.75 kr/h, so you would need 4 of them.
Gas heats the air, and wind carries that heat away almost instantly. Infrared warmth heats people directly, like sunlight. Every watt does more work, so fewer units are needed for the same comfort.
Based on Eurostat household electricity prices, H1 2025 (DE €0.383/kWh, SE ~2.40 kr/kWh incl. grid fees and tax). Gas: SE approx. 47 kr/kg. Calculated at 12 kW average output, 0.94 kg/h consumption. Actual costs vary with local prices and the selected power level.
