Radiant Heaters

For an outdoor patio, plan on roughly 1,000W (around 3,400 BTU/hr) of radiant output per 2-3 square metres of seating zone you actually want to keep warm, then adjust up or down for wind, climate, and how exposed the space is. Heatscope outdoor radiant heaters warm people and surfaces directly rather than heating the air, so the conventional gas-heater BTU maths does not apply. Very little energy is lost to drafts, and 87-94% of input wattage reaches the people below.

To work out the right output for your patio, weigh four factors:

• Footprint and seating zones. Define the area people will sit or stand in, not the whole patio. A 2,800W unit (about 9,500 BTU/hr) suits an intimate two to four-person setting; 3,000-3,200W units (roughly 10,200-10,900 BTU/hr) cover larger lounge or dining zones.
• Coverage type. Pergolas, eaves, and semi-enclosed patios hold radiant warmth well, so you can size at the lower end. Fully open decks and rooftops need higher wattage or a second unit.
• Climate and wind. Cool-temperate climates and exposed coastal sites push you toward 3,000W and above. Sheltered courtyards in milder zones run comfortably on 1,600-2,400W.
• Mounting height. Standard installation sits at 2,100-2,400 mm [83-94 in]. Higher mounts spread heat wider but reduce intensity at seated height, so larger or higher-mounted spaces benefit from multiple lower-output heaters spaced evenly rather than one high-output unit.

If you're between two outputs, choose the higher one with two-stage control. You can run at 50% on milder evenings and keep full output in reserve for genuinely cold nights.

Heatscope outdoor radiant heaters cover between 8 and 11 square metres [86 to 118 sq ft], depending on the model. Compact models deliver 8 m² of effective coverage, whilst higher-output models extend this to 11 m². These figures represent the zone of meaningful warmth, the focused area where mid-wave infrared energy directly heats people and objects in the beam, rather than diffusing energy into surrounding air the way ambient heaters do.

Coverage isn't determined by wattage alone; it's shaped by how infrared energy is directed. Adjusting the swivel-joint mount to angle toward your seating or dining zone concentrates the heat where you need it most. The two-stage output setting (50% and 100% power) lets you tailor intensity across that zone: higher output for full warmth, lower output to spread heat more gently. For larger entertaining areas, positioning multiple heaters with overlapping coverage zones extends heating efficiently without wasting energy on unoccupied spaces.

Unlike ambient outdoor heaters that lose effectiveness in wind, directional infrared maintains its coverage focus in open patios and exposed settings, making the stated coverage area consistent and reliable regardless of breeze conditions.

Yes, your HEATSCOPE® radiant heater must be connected to a residual current device (RCD), commonly called a safety switch in Australia. This requirement is set out in AS/NZS 3000:2018, the Australian and New Zealand wiring rules that govern all electrical installations.

The RCD protects the circuit by detecting electrical faults and disconnecting the power in milliseconds, preventing electric shock and fire risk. It is a standard requirement for all fixed electrical appliances in Australia and New Zealand, not a feature of the heater itself, but rather a circuit-level protection device that your electrician will install as part of the installation.

Your installation must be completed by an authorised electrician who will confirm the RCD is sized correctly for your heater's requirements and complies with local regulations.

For patio heating, electric outdoor radiant heaters and gas patio heaters take fundamentally different approaches, and the right choice depends on your space, design priorities, and how you want to operate the system. HEATSCOPE electric infrared heaters convert up to 94 percent of input energy directly into radiant warmth, heating people and surfaces within seconds with no combustion, no flue, and no fuel storage. Gas patio heaters burn LPG or natural gas to push out higher peak output, but much of that heats the surrounding air through convection, which dissipates quickly outdoors and in wind.

The practical differences across installation, maintenance, and design are:

• Installation: Electric is hardwired to a 220-240V circuit and mounts flush to a wall, ceiling, or extension rod. Gas needs either a piped supply with a licensed gas fitter or a swappable cylinder with floor space for the unit.
• Maintenance: Electric heaters have no burners, valves, or ignition components to service. Gas requires regular maintenance of those parts and periodic cylinder replacement.
• Use in covered spaces: Electric produces no combustion byproducts, making it fully suitable for enclosed alfresco areas, undercroft patios, and pergolas. Gas patio heaters require open or well-ventilated settings, which limits where they can be installed.
• Design: Electric infrared offers slimline aluminium chassis in black or white, smart-home control, and award-winning low-profile aesthetics. Gas patio heaters are typically freestanding units with a visible flame.
• Weather resistance: HEATSCOPE electric models carry IP25 to IP65 ratings for fixed outdoor exposure.

For design-led, low-maintenance patio heating, electric infrared is the clear specification choice, particularly in covered or semi-enclosed spaces where gas cannot go.

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.

Weather-resistant outdoor radiant heaters are designed as permanent outdoor fixtures, not classified as fully waterproof, but built and rated to the specific ingress protection standard that matches their installation environment.

Each Heatscope model carries a defined IP rating. The Pure Plus (IP65) handles fully exposed positions including driving rain and wind-blown dust. The Vision (IP44) and Next (IP25) suit covered and semi-sheltered positions. The Spot (IP24) works in covered outdoor areas with splash protection. No seasonal removal or weatherproof cover is required when the right model is matched to the right setting.

Permanent outdoor exposure is built into every design consideration. The aluminium chassis resists corrosion and will not discolour over years of outdoor service. There are no gas valves, ignition components, or combustion residues for moisture to degrade. Units are hardwired permanently into the outdoor electrical supply, not plugged in seasonally.

The single risk is mismatching a covered-area model with a fully exposed position. A heater specified for sheltered use will degrade under sustained open-air exposure. Correct IP-to-installation matching is what keeps a Heatscope heater performing reliably through all seasons.

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.

Weather-resistant Heatscope outdoor radiant heaters cover roughly 8 m² [86 sq ft] in the Spot range and 11 m² [118 sq ft] in the Vision range, with comparable footprints in the Pure+ and Next ranges depending on mounting height and angle. These are effective coverage figures for directed warmth, not ambient heating estimates.

The reason coverage stays predictable outdoors is the heating method itself. Infrared technology converts 90 to 94 per cent of input energy directly into radiant warmth that travels through air to people and surfaces, so wind and open volume have far less effect than they do on convective patio heaters. Heatscope's dual carbon spirals reach full output in 15 to 30 seconds and maintain a directed output, which is why coverage remains consistent across exposed terraces, balconies, and undercover dining areas.

• Mounting height: lower mounts concentrate heat over seating; higher mounts widen coverage and soften intensity.
• Beam orientation: angled or swivel-mounted units bias warmth toward where guests actually sit, rather than radiating into empty space.

For larger zones, multiple units can be paired or run on two-stage output. Confirm exact placement with a Heatscope specialist for the specific layout and ceiling clearance.

Direct heat transfer is the defining advantage of HEATSCOPE® radiant heaters. Unlike gas heating, which heats the air first and loses warmth to wind and surroundings, infrared heaters beam radiant heat directly to people and objects. You feel warmth in seconds rather than minutes, and wind does not steal the heat, a critical edge in outdoor settings.

Beyond heat delivery, electric infrared eliminates the infrastructure demands of gas. No gas lines, no flue or ventilation requirements, no specialist fitters. Wall or ceiling mounting takes two screws and a 220-240V circuit, freeing floor space and keeping heaters out of reach. Zero combustion byproducts mean the units are safe for enclosed outdoor spaces (patios under pergolas, covered dining areas, outdoor rooms) where ventilation limits would rule out gas.

The reliability advantage is significant. No valves, ignition components, or burners to service. No annual maintenance, seasonal prep, or gas-pressure issues. Silent operation with no fans stirring dust or allergens. One installation and the heater runs flawlessly year after year: the set-and-forget simplicity that appeals to hospitality operators and discerning homeowners alike.

When you compare the total ownership experience, including instant heat, no emissions, design freedom, and zero-service reliability, the case for radiant electric is compelling.

Weather-resistant outdoor electric heaters should carry an IP (Ingress Protection) rating to IEC 60529, CE marking confirming compliance with electrical safety directives, and residual current device (RCD) protection as a hardwired installation requirement.

IP ratings are the most critical certification for outdoor use. The first digit indicates dust protection; the second indicates water resistance. IP24 is the minimum for covered patio installations, IP44 suits alfresco areas exposed to water spray from any direction, and IP65 confirms full protection against water jets and wind-driven dust, appropriate for fully exposed outdoor positions. Matching the heater's IP rating to the exposure level of the installation is the most important purchasing decision.

CE marking confirms that a heater meets European Union health, safety, and environmental requirements. For markets outside Europe, look for equivalent regional marks from independent certification bodies that verify electrical safety.

All Heatscope heaters carry model-specific IP ratings verified through testing protocols developed in Germany. Installation requires a licensed electrician with RCD protection built into the dedicated circuit, a safety requirement that applies across all IP ratings.
