The two categories solve different problems and use different infrared bands.

Outdoor heaters (V40, V50, V70, S50, S70, I90) use mediumwave infrared centered around 2.2 µm. This wavelength penetrates wind and open air without losing intensity, which is why outdoor heating needs it. Power output is high (up to 2300 W on PRO V70) and IP rating is up to IP65.

Indoor panels (P5 Metal, P6 Hybrid, P7 Glass) use longwave infrared above 3 µm. This is gentler, suited to enclosed spaces, and converts approximately 99% of electrical input into radiant heat. Panels heat walls and floors, which then maintain stable room temperature without air movement.

Outdoor models are not used indoors because their intensity and short-wavelength output are designed to overcome wind and distance, which is unnecessary in a closed room.

Opranic indoor panels (P5 Metal, P6 Hybrid, P7 Glass) convert approximately 99% of electrical input into radiant heat. There are no fans, ducts or combustion losses, so almost all electricity becomes useful warmth.

Real-world running cost depends on three factors:

• Room insulation: a well-insulated room holds infrared heat well; surfaces stay warm and re-radiate
• Panel sizing: an undersized panel runs continuously and costs more; correctly sized panels cycle on and off
• Use pattern: infrared excels at heating occupied zones, not whole houses, so they are most efficient when used per room

For a typical 15 m² well-insulated room, a 700 W P5 panel running 6 hours a day at €0.30/kWh costs about €1.26 per day. Use the heat calculator on the site to estimate your specific case.

Opranic indoor panels deliver several real health benefits over forced-air or convection heating. The mechanism matters: infrared warms surfaces and people directly without moving air, and that changes the indoor environment.

• No air circulation means dust, pet dander, pollen and other allergens are not stirred up into the breathing zone. Significant for asthma, allergies and households with children.
• Stable humidity is preserved because air is not heated and dried out. Reduces dry skin, dry eyes and sore throats common with conventional heating.
• Therapeutic warmth penetrates a few millimetres into skin and muscle, which can ease stiffness and improve local circulation. Useful for arthritis sufferers and after physical work.
• Silent operation with no fans or moving parts. Better for sleep environments, study spaces and quiet rooms.
• No combustion means no nitrogen oxides, carbon monoxide or other byproducts indoors.

Yes. Several Opranic indoor models are specifically rated for bathroom installation, with IP44 and IP24 protection against splash and spray water.

Infrared works particularly well in bathrooms for two reasons. First, the radiation warms the user directly the moment they step out of the shower, which is exactly when warmth is needed most. Second, the heat keeps walls, mirrors and ceilings dry, which prevents condensation, mould growth and the foggy mirror problem common in poorly ventilated bathrooms.

For installation, follow the IP-zone rules in your country. IP44-rated panels can typically be installed in Zone 2 (within 60 cm of the bath/shower), and IP24-rated heaters in Zone 1 with proper electrical isolation. Always consult an electrician for bathroom installations.

Infrared heaters complement central heating by solving the specific problems central systems are bad at: zone heating, fast response and targeted comfort.

Zone heating. Most homes have rooms that are used a few hours per day (home office, guest room, basement workshop). Heating these to comfort via central heating means heating the whole house. An infrared panel in the room handles only that space, while central heating runs at a lower baseline.

Fast response. Central heating takes 30-60 minutes to noticeably warm a cold room. Infrared delivers felt warmth within seconds because it heats people directly, not the air mass. Useful for autumn/spring shoulder seasons when you do not want to start the main system.

Targeted comfort. Bathrooms, conservatories, rooms with large windows or exposed corners often have cold spots central heating cannot fix. A single infrared panel in those zones is more efficient than raising the thermostat for the whole house.

Used this way, you typically lower the central heating set point by 1-2 °C and use infrared where you actually are. Net energy use usually drops.

Energy consumption is determined by physics, not marketing claims. The main variables are:

• Wattage matched to the room. Undersized heaters run continuously and never reach comfort. Oversized heaters cycle off too aggressively. As a rule of thumb for well-insulated rooms: 60-80 W per m². Use the heat calculator on the site for an exact figure.
• Run time. Use the heater when occupied, not as background heat. Infrared delivers comfort immediately, so there is no benefit to leaving it on when nobody is in the room.
• Room insulation. Heated surfaces re-radiate warmth back into the room. Poor insulation lets that warmth escape and the heater works harder. Sealing draughts has a much larger effect than people expect.
• Placement. Obstructions block radiation. Keep at least 40 cm clear in front and around the heater. Position so it faces the occupied zone directly.
• Thermostat use. Models with built-in thermostats only draw power when needed. Without a thermostat, the heater runs at full power continuously.
• Local electricity price. Time-of-use tariffs make a significant difference. Heating during off-peak hours (typically nights and weekends) can cut running cost by 30-50%.

Six concrete actions, ranked by impact:

1. Position correctly. Place the heater facing the zone you actually occupy. Wall-mount in living areas at 80-100 cm height (seated) or 140-160 cm (standing). Avoid placing behind furniture.
2. Use a thermostat. Models without one run at full power until switched off. A simple plug-in thermostat reduces consumption by 20-40% in most cases.
3. Zone heating. Heat only the rooms you use. Close doors to unused spaces. Lower the central heating set point by 1-2 °C and use infrared where needed.
4. Seal draughts. A cold draught at floor level forces any heater to work harder. Door brushes, window seals and chimney baffles cost very little and have outsized effect.
5. Use natural heat. Open curtains during sunny daylight hours, close them at dusk. The thermal mass of the room itself becomes free heat storage.
6. Time-of-use tariffs. If your electricity provider offers off-peak rates, run the heater during those windows when possible. The room re-radiates accumulated warmth for hours.

Yes. Safety is engineered into every Opranic indoor panel through a combination of certifications, materials and built-in protections.

• Overheating protection automatically cuts power if the surface temperature exceeds safe limits, preventing fire risk even in fault conditions.
• Overvoltage protection guards the heater electronics against grid surges.
• Splash resistance rated IP44 (P5, P6) or IP24 (P7) for safe use in bathrooms and other moisture-prone areas.
• Tempered glass and anodized aluminum construction with no exposed heating elements. Surface temperatures stay within touch-safe ranges on most models.
• International certifications including CE, RoHS, REACH and EMC. Means the panels meet EU safety, environmental and electromagnetic standards.
• Rear thermal insulation prevents wall and ceiling heat damage and improves efficiency by directing all heat into the room.
• No combustion or emissions. Unlike gas heaters, there is no carbon monoxide risk and no oxygen depletion.

Placement determines whether the heater performs at its potential or wastes energy. Key principles:

• Mounting height. Wall-mounted panels work best at 80-100 cm above the floor in seated areas (living rooms, offices) and 140-160 cm in standing areas (kitchens, hallways). Ceiling mounting works at 220-260 cm for most rooms.
• Clear space in front. Maintain at least 40 cm clearance between the heater and any furniture, curtains or large objects. Obstructions absorb radiation that should reach occupants.
• Face the occupied zone. Aim the heater at where people actually sit, stand or work. Heating an empty corner is wasted energy.
• Distance from windows. Avoid mounting directly above or below large windows. Cold draughts will offset the heating effect. Place a few metres away with the panel facing inward.
• Multiple panels in large rooms. For rooms over 25 m² or with irregular shapes, two smaller panels on opposing walls work better than one large unit. Even heat distribution beats raw wattage.
• Consider room features. Vaulted ceilings, exposed brick walls, large amounts of glass or open floor plans all change the optimal placement. Use the heat calculator for room-specific recommendations.

Power cable length is 1.85 to 1.95 metres depending on the model. The plug is a European-type F plug (Schuko), compatible with standard EU outlets.

This length is sufficient for most installations where the heater is mounted within reach of an outdoor-rated socket. For installations requiring a longer reach, see the FAQ on extension cords or have an electrician install a dedicated outlet at the mounting position.

The two categories solve different problems and use different infrared bands.

Outdoor heaters (V40, V50, V70, S50, S70, I90) use mediumwave infrared centered around 2.2 µm. This wavelength penetrates wind and open air without losing intensity, which is why outdoor heating needs it. Power output is high (up to 2300 W on PRO V70) and IP rating is up to IP65.

IR-X Carbon Black is the proprietary emitter technology used in all Opranic outdoor heaters. It is built on a carbon-based filament that operates at filament temperatures up to 1050 °C and emits peak infrared radiation at 2.2 µm at full power.

The wavelength is the critical part. At 2.2 µm the radiation is short enough to travel through wind and cold air without significant loss, but long enough that human skin absorbs it efficiently. Cheaper halogen heaters typically peak around 1.0 to 1.5 µm, where much of the output is lost as visible glare and reflected energy.

IR-X Carbon Black also runs cooler at lower power settings. At P1 (40% output) the peak shifts to 2.7 µm, which is gentler and ideal for low-intensity comfort heating in mild conditions.

Opranic outdoor heaters emit infrared radiation between 2.2 µm and 2.7 µm depending on the power setting. At full power (P5, 2300 W on PRO V70), the peak emission is 2.2 µm. At reduced power (P1, 920 W), the peak shifts to 2.7 µm.

This range, sometimes called mediumwave or IR-B, is selected for outdoor heating because:

• It penetrates moving air and open spaces without significant energy loss
• Human skin and clothing absorb it efficiently
• It produces minimal visible glare compared to shortwave halogen heaters

The 5-step power control via triac on the PRO V70 PCB lets you choose the wavelength that matches outdoor conditions: shorter wavelengths for cold and windy days, longer for mild evenings.

Yes. All Opranic outdoor heaters are rated for outdoor use, with the highest models reaching IP65.

• PRO V70 and THOR S70: IP65 (fully dust-tight, protected against water jets from any direction)
• NOVA V50 and S50 THOR: IP55 (dust-protected, protected against low-pressure water jets)
• I90 VEGA: IP54 (dust-protected, protected against splashing water)

IP65 means a heater can be installed in fully exposed locations, including pergolas, terraces and outdoor restaurants where rain and snow are routine. The lower-rated models are suitable for partially covered installations such as under an awning or balcony roof.

Yes. Opranic outdoor heaters are designed for year-round Nordic conditions including snow, rain and sub-zero temperatures.

The IR-X Carbon Black emitter actually performs better in cold weather, because the temperature differential between the heater and the surrounding air is larger, making the radiated warmth more noticeable. The IP65 rating on PRO V70 and THOR S70 means rain and snow do not affect operation or safety.

For installation in fully exposed positions (no roof or awning above), choose IP65-rated models. For locations under a roof, awning or pergola, IP55 or IP54 models are also suitable.

Unlike gas patio heaters, Opranic units start instantly in cold weather, with no preheating, no fuel issues and no flame to be extinguished by wind.

“E3” indicates that the tilt switch has been activated. The tilt switch protects the heater from operating when tipped over. It can be reset, and on the STAR18RS the protection can also be disabled if you need to operate the heater in a non-standard orientation.

To reset: simply return the heater to upright position and power-cycle it.

To disable the tilt switch entirely (deliberately made non-obvious to prevent accidental disabling):

1. Unplug the heater. Have the remote control ready, you only have a few seconds after reconnecting.
2. Plug back in. When you see the lights circling, press timer button (bottom-right), thermostat button (bottom-left) and level button (centre) within 2 seconds.
3. If successful, the display shows the letter A (active) or P (passive). Default is A.
4. Use + and − buttons to toggle between A and P. Set to P to disable the tilt switch, then power off via the main switch.
5. On next power-up, the tilt switch stays disabled until you repeat the process.

Video walkthrough: opranic.com/external/video/norveco_star18rs_tilt.mp4

“ER” on V50 or V70 series with remote control indicates the electronic tilt switch has been triggered.

Quick reset: Make sure the heater is positioned with the LCD screen facing up, or angled up to 90° left or right. Never face down. Power-cycle the heater.

To disable the tilt switch permanently (required for ceiling or wall mounting in non-vertical orientations):

1. Power on the heater (turn on the wall switch or plug in).
2. Immediately press T− followed by T+.
3. Display will show OF (tilt protection deactivated) or ON (active).
4. Select OF to disable.

Once disabled, the heater operates in any orientation and can be wall- or ceiling-mounted.

Safety note: When the tilt switch is disabled, the heater must NOT be placed on a stand or in any portable configuration. Wall or ceiling mounting only.

Power cable length is 1.85 to 1.95 metres depending on the model. The plug is a European-type F plug (Schuko), compatible with standard EU outlets.

This length is sufficient for most installations where the heater is mounted within reach of an outdoor-rated socket. For installations requiring a longer reach, see the FAQ on extension cords or have an electrician install a dedicated outlet at the mounting position.

Minimum height: 1.8 metres from floor to bottom of heater, in accordance with CE regulations. This is non-negotiable for safety and certification.

Recommended heights by model and use case:

• V50 NOVA, V70 PRO, S50 THOR, S70 THOR (up to 2300 W): 1.8-2.3 metres for terraces and patios. Lower heights give more intense direct warmth, higher heights spread the heat over a larger area.
• I90 VEGA series (commercial high-output): 4.0 metres minimum. The VEGA emits at higher intensity and requires more vertical clearance.

For ceiling-mounted installations, ensure the tilt switch has been disabled (see V50/V70 troubleshooting FAQ) and use only ceiling-rated brackets.

Yes. The remote control is universal across all Opranic remote-controlled heaters (the “R” versions: V70R, S70R, S50R, etc.). One remote operates all units within range.

Operating range: 8-10 metres from the heater. Point the remote toward the heater you want to control and press the desired power level.

Because the signal reaches all heaters in range simultaneously, all units in front of you will respond to the same command. For installations with multiple heaters that need independent control, position them so each is in a different zone, or operate from a position closer to the target heater.

If you lose or break a remote, replacement remotes are available through customer service.

No. Thermostatic models do not have manual power-level settings. They have a single output (typically maximum) and use an internal temperature sensor to cycle on and off.

How it works:

• You set the desired temperature on the thermostat dial.
• The heater runs at full power until the heating element reaches that temperature.
• It then cycles off and on as needed to maintain the setting.

This means thermostatic models work well for set-and-forget continuous operation. They are not ideal if you want to vary the felt warmth manually.

For variable manual power control (5 levels: P1 to P5, 920 W to 2300 W), choose a non-thermostatic remote-controlled model such as PRO V70R or THOR S70R. These let you dial the output to match conditions: lower setting on mild evenings, higher setting on cold or windy days.

Opranic outdoor heaters have the highest wind resistance of any patio heater on the market because of how IR-X Carbon Black emits.

The physics: radiation travels through air without losing energy. A breeze does not weaken the infrared waves themselves. What wind does is cool exposed skin via convection, which offsets the felt warmth from the heater.

Opranic outdoor models convert 96% of electrical input into radiant heat, with peak emission at 2.2 µm (IR-X Carbon Black). Skin and clothing absorb this wavelength very efficiently, so even in moderate wind the felt warmth remains significant.

Coverage rules of thumb (PRO V70 at 2300 W):

• Indoor / fully sheltered: ~23 m² of comfort coverage
• Outdoor / unsheltered: ~13 m² of comfort coverage

For windy locations or fully exposed terraces, use either a higher-output model (PRO V70 at full P5) or two units distributed for overlapping coverage. The heat calculator on the site computes coverage adjusted for shelter, ceiling, wind exposure and ambient temperature.

No. Opranic does not offer stands for wall-mounted models, and we strongly recommend against improvising one.

Wall-mounted heaters (V50, V70, I90) are engineered, tested and certified for fixed wall or ceiling installation. Mounting one on a stand changes the heat distribution, may exceed tilt switch limits, can void the warranty, and in some jurisdictions violates safety regulations.

For portable heating, choose a model designed for it:

• THOR S50 / S70: freestanding versions with the same IR-X Carbon Black emitter as PRO V70. Stable base, integrated cable management, certified for portable use.
• STAR series (V40 STAR): compact freestanding option for smaller spaces.

Both alternatives provide the same heating performance as the wall-mounted versions, in a configuration that meets all relevant safety standards.

Yes. Opranic outdoor heaters are built from materials specifically chosen for long-term outdoor exposure to rain, snow, UV and salt air.

Material breakdown:

• Housing: anodized aluminum. Highly corrosion-resistant, virtually unaffected by outdoor use over many years.
• Front grille: chrome-plated steel. Durable but can show some patina in coastal or industrial environments over time. Replacement grilles are available through customer service if appearance becomes a concern.
• Side covers: fiberglass-reinforced plastic. Very high resistance to UV, temperature cycling and weather. Will not crack or fade under normal use.

To maximize heater lifespan:

• Install under a roof, awning or pergola where possible
• Cover the heater during extended periods of non-use (winter storage, off-season)
• For coastal installations, rinse occasionally with fresh water to remove salt deposits

If a side cover breaks (typically from being dropped during installation), contact us for a replacement. We stock spare parts for all current models.

No. Thermostatic models do not have manual power-level settings. They have a single output (typically maximum) and use an internal temperature sensor to cycle on and off.

No. The radiation infrared heaters emit is electromagnetic radiation in the infrared band, which sits just below visible light on the spectrum. It is the same type of warmth you feel from sunlight, fireplaces and any heated object.

It does not contain ultraviolet (UV), which is the part of sunlight responsible for skin damage. It does not contain ionising radiation. It cannot damage cells, DNA or tissue at the wavelengths and intensities used in heating.

Infrared has been used safely in medical applications, food warming and industrial drying for over 80 years.

Yes, provided you respect the safety distances specified in the installation manual. The exact clearances depend on the model and power output.

General guidelines for wood-wall mounting:

• Behind the heater: follow the rear-clearance value in the manual (typically the heater is fine flush against the wall thanks to rear thermal insulation).
• Above the heater: minimum 50 cm to any combustible material or ceiling overhang.
• To the sides: minimum 30 cm to combustible side surfaces.
• In front: minimum 1.5 metres to combustible material at low power, more at higher settings.

For high-power outdoor models (V70 PRO at 2300 W), use a thermal backing plate or non-combustible wall panel for additional safety. The full installation manual is available in the media library on each product page.

Power cable length is 1.85 to 1.95 metres depending on the model. The plug is a European-type F plug (Schuko), compatible with standard EU outlets.

This length is sufficient for most installations where the heater is mounted within reach of an outdoor-rated socket. For installations requiring a longer reach, see the FAQ on extension cords or have an electrician install a dedicated outlet at the mounting position.

Minimum height: 1.8 metres from floor to bottom of heater, in accordance with CE regulations. This is non-negotiable for safety and certification.

Recommended heights by model and use case:

• V50 NOVA, V70 PRO, S50 THOR, S70 THOR (up to 2300 W): 1.8-2.3 metres for terraces and patios. Lower heights give more intense direct warmth, higher heights spread the heat over a larger area.
• I90 VEGA series (commercial high-output): 4.0 metres minimum. The VEGA emits at higher intensity and requires more vertical clearance.

For ceiling-mounted installations, ensure the tilt switch has been disabled (see V50/V70 troubleshooting FAQ) and use only ceiling-rated brackets.

Avoid extension cords whenever possible. Infrared heaters draw 2000-2300 W continuously, and undersized extension cords overheat. This is the leading cause of fire risk in heater installations.

If you must use an extension cord:

• Conductor cross-section minimum 1.5 mm²
• Rated current minimum 10 A
• As short as possible, ideally under 5 metres
• Fully unwound from the reel (a coiled cord under load can overheat severely)
• Only the heater on the cord. Never connect multiple appliances

For permanent installations, have an electrician install a dedicated outdoor-rated outlet at the heater position. Cost is minimal and removes the fire risk entirely.

Opranic offers a 2-year standard warranty on all heaters. For indoor panels (P5 Metal, P6 Hybrid, P7 Glass), the warranty extends to 5 years when the product is registered after purchase.

The warranty covers manufacturing defects, premature emitter failure, electronic component failure and structural defects. It does not cover damage from incorrect installation, modification, or use outside the rated environmental conditions.

Yes. Opranic outdoor heaters are built from materials specifically chosen for long-term outdoor exposure to rain, snow, UV and salt air.

Material breakdown:

• Housing: anodized aluminum. Highly corrosion-resistant, virtually unaffected by outdoor use over many years.
• Front grille: chrome-plated steel. Durable but can show some patina in coastal or industrial environments over time. Replacement grilles are available through customer service if appearance becomes a concern.
• Side covers: fiberglass-reinforced plastic. Very high resistance to UV, temperature cycling and weather. Will not crack or fade under normal use.

To maximize heater lifespan:

• Install under a roof, awning or pergola where possible
• Cover the heater during extended periods of non-use (winter storage, off-season)
• For coastal installations, rinse occasionally with fresh water to remove salt deposits

If a side cover breaks (typically from being dropped during installation), contact us for a replacement. We stock spare parts for all current models.
