Radiant Heaters

Weather-resistant radiant heaters warm people and surfaces directly through infrared waves, while convection heaters warm the surrounding air, making radiant the practical choice for outdoor use. Air is largely transparent to mid-wave infrared, so the energy travels through open space and is absorbed by skin, tables, floors and nearby objects, much like warmth from the sun on a cool day.

Convection relies on still air to build a pocket of warmth around you. Outside, that pocket drifts away on the first breeze, taking comfort with it.

Heatscope's carbon spiral technology converts up to 94% of its energy into directed infrared heat, so warmth holds its focus even in exposed patios, courtyards and open-fronted venues. Start-up is near-instant, and because there is no flue or ventilation requirement, placement follows the design of the space rather than the other way around.

The best HEATSCOPE radiant heater for your space depends on three practical factors: the location's exposure to weather, the size of the zone you're heating, and your aesthetic preference.

If your space is fully exposed to outdoor elements, such as a rooftop, deck, or open patio, the Pure Plus model's IP65 rating and all-weather design make it the most resilient choice. For semi-covered areas like sheltered patios or balconies, the Spot delivers compact, rapid heat-up (under 15 seconds) across an 8 m² zone, or choose the Vision for larger spaces needing 11 m² coverage with minimal light output from the ceramic glass front.

Consider how you experience the space. The Spot and Vision both offer IP24 weather protection, whilst the Spot's smaller form factor suits intimate areas and the Vision's 1,661 mm width creates a more substantial focal point. All three operate at dual 50/100% power settings and deliver heat in 15-60 seconds depending on the model.

Discuss your specific location, intended installation position, and aesthetic priorities with our specialists, who will recommend which model aligns with your project needs.

• HEATSCOPE® radiant heaters draw between 6.96 and 13.91 amperes at full power, depending on the wattage rating of your model. The Spot 1600W draws 6.96A; the Spot 2800W draws 12.17A; the Vision 3200W and Pure 3000W both draw approximately 13A at 100% power.
  ⁠All HEATSCOPE® models operate on 220–240V single-phase supply at 50–60Hz. Most models feature dual power stages, which means you can also run them at 50% power; at this setting, the current draw reduces proportionally. For example, a Vision 3200W operating at 50% would draw roughly 6.95A instead of the full 13.91A.These specifications are essential for circuit planning. Confirm your installation supports the required amperage with a qualified electrician before commissioning the heater.

Radiant heating is the direct transfer of thermal energy from a heat source to solid objects and people using electromagnetic waves, without heating the surrounding air. Heatscope electric radiant heaters emit mid-wave infrared radiation from their carbon heating elements; this energy travels directly through space like sunlight, warming surfaces, bodies, and furniture beneath them rather than heating the air in between.

The mechanism is precise: electric current energises carbon spirals, which glow and emit infrared waves. These waves are absorbed directly by skin and surfaces, creating pleasant, enveloping warmth. Because the heat travels to objects rather than dispersing into air, 87–94% of input electricity converts into usable ambient heat, substantially more efficient than convection-based systems. The directional nature of radiant heat makes it effective even in windy or draughty outdoor conditions, where air-based heating fails. Full warmth output arrives in as little as 15 seconds.

Yes, weather-resistant outdoor radiant heaters are purpose-built for covered areas like pergolas, and a sheltered structure is the ideal setting for infrared heating. Because the heat travels in a direct beam to warm people and surfaces rather than the surrounding air, a pergola roof helps contain that warmth without the wind dispersion open patios experience.

Pergola installation comes down to clearances and mount choice. Heatscope models accept wall or ceiling mounting across the range, with a minimum 1,800 mm [70.9 in] clearance from the lower edge of the unit to the floor, and 200 mm [7.9 in] from any power source. When the pergola ceiling sits lower than standard, extension rods of 100, 300 or 500 mm drop the heater to the correct height. Timber pergolas are fine with Heatscope spacers, which maintain the recommended distance from combustible material. Installation must follow local electrical wiring standards and be carried out by a licensed electrician, connected through a residual current device (RCD).

No, radiant heating does not degrade indoor air quality. Heatscope Heaters use mid-wave infrared radiation, which transfers heat directly to solid objects (people, furniture, and floors) without heating the air itself. This fundamental difference from forced-air heating systems creates distinct air-quality benefits.

Because radiant heaters have no fan or blower, there is no convection to disturb dust, pollen, or other particulates. The sealed construction (IP25–IP65, depending on model) prevents internal particulate accumulation. There are no combustion byproducts, ventilation requirements, or filters to maintain.

Radiant heating also does not alter humidity levels the way forced-air systems do. You get even thermal comfort without the dry-air side effects common to traditional heating. For users with allergies or asthma, the absence of air circulation and combustion makes radiant heaters a practical choice for creating a quieter, cleaner indoor environment.

Direct heat transfer is the fundamental advantage of radiant heating, which warms people and objects in its path rather than heating the surrounding air. This delivers several distinct benefits: energy conversion rates of 87–94%, near-instant warmth within 15–60 seconds depending on the model, and silent operation with no moving parts. Radiant heaters produce no emissions, odours, or ash, and require no gas lines, flue systems, or ventilation infrastructure, making them ideal for retrofit installations and spaces where traditional heating isn’t practical.

The trade-off is directional coverage. Radiant heaters warm only the areas within their line-of-sight. Someone standing outside the beam path receives minimal benefit. This also means they function as zone heaters rather than whole-room ambient heating, effective for creating comfort zones in outdoor entertaining areas or specific indoor spaces, but less efficient for warming every corner of large rooms simultaneously. Covering expansive areas requires multiple units, which carries a higher upfront cost than a single centrally-mounted system. Installation demands appropriate electrical infrastructure (220–240V, professional installation), and in cold climates, multiple heaters may be necessary to achieve ambient comfort comparable to forced-air or hydronic systems.

Rather than limitations, many customers view these characteristics as precision advantages: the ability to heat only occupied spaces, reduce energy consumption, and extend the usable season in outdoor areas without the capital expense of full-home heating infrastructure.

The Pure Plus suits fully exposed outdoor installations, Vision minimises visible light for sheltered alfresco dining, Next covers semi-open and indoor-outdoor transitions, and Spot provides compact, targeted directional warmth. Weather-resistant requirements are the primary filter.

Pure Plus is the definitive choice for open-air patios, pool surrounds, and unroofed terraces. It carries the highest weatherproof rating in the range (IP65) and uses a convex SCHOTT NEXTREMA glass-ceramic front that spreads sun-like warmth evenly while softening the visible glow.

For covered alfresco rooms, loggias, and sheltered dining zones where atmosphere matters alongside warmth, Vision is the model to consider. Its ceramic glass front reduces visible light to a minimum, creating the most ambient footprint of the range at 3,200W, the highest heat output in the lineup.

Next suits semi-open terraces, verandahs, and spaces that shift between indoor and outdoor use. Its slim aluminium profile fits flush to wall and ceiling surfaces without visual bulk.

Spot concentrates directional infrared on a specific zone, a balcony, a covered nook, or a set of seats, and comes in two output levels to match the space.

Every range includes two-stage output control and a 2-year warranty. ZigBee smart control is available as an optional accessory on most models.

HEATSCOPE® radiant heaters deliver direct heat transfer using mid-wave infrared technology that penetrates the first skin layers, creating genuine sun-like warmth rather than surface heating. Unlike many electric outdoor heaters that rely on short-wave infrared producing bright red glows and uncomfortable high-intensity heat, HEATSCOPE® heaters use colour-matched grill screens to reduce light output to just 30-40% of traditional radiant heaters. The Spot series produces approximately 600 lumens (per product specifications), whilst the Vision and Pure Plus ranges deliver less than 300 lumens, preserving outdoor ambience without harsh brightness.

The engineering differences extend to durability and materials. HEATSCOPE® heaters use carbon fibre heating elements and, in the Pure Plus range, SCHOTT NEXTREMA® premium convex glass, a material exclusivity among electric infrared heaters. The Pure model achieves IP65 weather resistance (dust and waterproof), exceeding the typical IPX5 rating of competitors, ensuring reliable outdoor performance across seasons.

For connected home environments, an optional ZigBee Bridge enables wireless control, motion sensors for automated triggering, and compatibility with Alexa and Google Assistant. An optional WiFi Smart Switch adds smartphone app control. Dual power levels at 50% and 100% output allow precise zone heating for energy efficiency without waste.

HEATSCOPE weather-resistant infrared heaters reach full output in under 15 seconds on most models; the glass-fronted range reaches comfortable warmth in under 60 seconds. You feel the warmth almost the moment the heater switches on, because infrared radiation travels through the air like sunlight and warms people and surfaces directly rather than heating the surrounding atmosphere.

That direct-to-body transfer is why outdoor patio heating with infrared behaves differently from a gas patio heater or a fan heater. There is no lag while the air temperature climbs, and almost no heat loss to wind or open sides of a pergola. Two practical benefits follow:

• Guests arriving to a cold terrace feel warmth within seconds of the heater being switched on, rather than waiting 20 to 30 minutes for air temperature to rise.
• Instant-on, instant-off operation means you only run the heater during occupied moments, keeping energy use close to actual occupancy time.

Carbon fibre elements are rated for at least 10,000 operating hours, and radiant efficiency across the range sits between 87 and 94 percent, so that fast warmth is delivered consistently across years of residential or commercial use.
