Radiant Heaters

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.

Carbon spiral heating technology uses two coiled carbon filaments, energised by an electric current, to produce mid-wave infrared radiation that warms people and surfaces directly. Heatscope’s weather-resistant range encloses this technology in housings rated for outdoor exposure, maintaining full performance in open patios and exposed living areas.

Heatscope uses carbon spirals because they generate heat as the primary output, not light. Most outdoor radiant heaters rely on light tubes that produce brightness first, with heat arriving as a by-product and an aggressive red glow. Carbon spirals reverse that priority, operating at filament temperatures of 1,100–1,300°C [2,012–2,372°F] and a colour temperature of 1,550–1,650 K, producing only 30–40% of the visible light of traditional radiant heaters. The result is sun-like warmth absorbed just under the first layers of skin, with no harsh glare to flatten the colour of food, joinery or lighting design.

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.

Infrared radiant heating technology uses direct heat transfer: electromagnetic waves deliver warmth from the heater to people and surfaces, bypassing the surrounding air entirely. HEATSCOPE radiant heaters emit mid-wave infrared radiation that is absorbed by solid objects (people, floors, surfaces) on contact. Because air is largely transparent to these wavelengths, warmth is not lost to wind, draughts, or dispersal in open spaces.

Mid-wave infrared is quickly absorbed by solid surfaces and skin, replicating the natural sensation of direct sunlight without heating the air around you. HEATSCOPE's dual carbon spiral heating elements emit this radiation through ceramic glass fronts with minimal visible light, delivering quiet, directed warmth. Designed to German engineering standards, this technology performs consistently indoors and in exposed outdoor environments.

• 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.

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 offers four ranges of weather-resistant electric infrared heaters, each engineered for different settings and design preferences. All use double carbon heating elements with two-stage output control and come in black or white with optional extension rods.

The Spot is the most compact, available in 1,600W or 2,800W, ideal for smaller spaces and directional warmth. Its ceramic glass front delivers radiant efficiency above 94%, with an IP24 rating suitable for covered outdoor areas.

The Pure Plus is the most weather-resistant in the range, rated IP65 for fully exposed outdoor installation. This 3,000W heater features a convex glass-ceramic front and won a Red Dot Design Award in 2018.

The Vision produces the highest output at 3,200W and runs the longest at 1,661 mm, creating ambient atmosphere alongside substantial warmth. Its minimal visible light (300 lm) suits settings where you want heat without visual prominence. It’s rated IP44.

The Next suits transitional spaces, including semi-enclosed terraces or indoor/outdoor transitions. Its 3,000W output and swivel-joint mount offer directional flexibility; its slim aluminium body fits tighter design schemes. It’s rated IP25.

All ranges include a 2-year warranty and optional ZigBee smart control.

Yes, Heatscope radiant heaters can be used in the rain, though suitability depends on your model's weather protection rating. Our heaters are engineered with IP ratings that specify their water-resistance capability, allowing us to rate them for different outdoor conditions.

Our highest-rating models carry IP65 certification, meaning full protection against dust and direct water jet spray, suitable for fully exposed outdoor installations without shelter. Other models in our range achieve IP25 to IP24 ratings, which provide splash-water protection and work best in partially covered areas such as patios with an overhang or pergola.

Beyond the IP rating, installation technique enhances durability. A slight downward mounting angle helps water run clear of electrical components. Positioning the heater under an eave or pergola extends the usable season, even for splash-rated models, letting you heat covered outdoor spaces across rainy months. All Heatscope heaters undergo rigorous German engineering testing protocols that validate weather performance. Check your specific model's IP rating when selecting an installation location to ensure the right match for your space's exposure.

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).

Two-stage output control lets weather-resistant HEATSCOPE radiant heaters switch between 100% and 50% power, so you can match heat delivery to conditions without turning the heater off. On a mild evening, 50% output keeps a patio comfortable while roughly halving energy draw; on colder nights, full power delivers the direct infrared warmth the heaters are engineered for.

The two levels are switchable from a wall switch, an included or optional 2-step infrared remote, or, with a WiFi wall switch, a smartphone and voice assistants like Alexa and Google Assistant. One remote can pair with multiple heaters, which is useful across larger covered areas or split zones in a restaurant or bar setting where different sections need different heat levels at once. ZigBee accessories extend this further on select models for motion-triggered or scene-based control.

Because HEATSCOPE heaters draw significant power at full output, the levels are fixed at 50% and 100%; a standard dimmer is not compatible. That fixed step is deliberate. It protects the heating elements and keeps infrared output stable and efficient at both settings.
