About infrared radiation (wavelengths, effectiveness, etc.)

First of all, infrared radiation has nothing to do with whether (red) light is visible or invisible. All infrared radiation is invisible, but the respective wavelength makes the difference.

IR-C long waves of the kind emitted by HEATSCOPE Zero heaters reach only about 1 millimetre under the skin. The ambient temperature increases noticeably, and your skin feels comfortably warm. This kind of infrared radiation is very sensitive to wind, however, and should only be used in enclosed rooms or fully wind-protected areas.

The HEATSCOPE Vision series emits IR-B midwave rays. They reach only approx. 1.5 to 2 millimetres under the skin. The result: slight warming of the ambient temperature with a comfortably warm feeling on the skin. This type of infrared radiation is suitable for interior areas and wind-protected outdoor areas.

HEATSCOPE Spot heaters emit IR-B fast midwave radiation as soon as they are turned on. These rays reach approx. 2 to 2.5 millimetres under the skin and create a very comfortable feeling of warmth. Since they generate less ambient heat, temperatures in the heating coverage area are always at a very comfortable level. Fast midwave heaters can also be used in more wind-prone areas.

Our Infrared section provides more detailed information. Click here to learn more about the function and effectiveness of infrared radiation.

The long-wave, midwave and fast midwave radiation emitted by HEATSCOPE infrared heaters is completely harmless. There is no harsh red light that can make your eyes hurt, but at most a pleasant ambient light between 0 and 600 lux (much darker than sunlight). The heat you feel is the result of a natural process. The heat reaches only about 2.5 millimetres under the skin with HEATSCOPE Spot heaters. With the Vision and Zero models, it reaches at most 2 mm under the skin.

How HEATSCOPE infrared radiant heaters work

Infrared radiant heaters like the Zero, Vision and Spot series from HEATSCOPE deliver heat more directly than classic heating systems or “mushroom-type” patio heaters that work by first heating the surface of various materials. Since they lose very little heat that rises into the air, as it does with with traditional systems, HEATSCOPE Zero, Vision and Spot heaters operate much more efficiently.

Unlike “mushroom-type” patio heaters, HEATSCOPE infrared radiant heaters generate heat directly. They have much lower operating costs, a broader heating coverage area, and generate significantly less CO2. Unlike “mushroom-type” patio heaters, HEATSCOPE infrared heaters spread their heat more evenly and are much more effective since they don’t require liquid-gas containers that must be replaced regularly. They also emit no smells and no noise, because they operate with electricity (220-240 V AC, 50 Hz).

“ZE” is the code for “zero-light heater. The HEATSCOPE Zero is an advanced development of the Heatstrip™, which we produced until early 2014 but is no longer sold.

“VE” and “VT” stand for “Vision” heaters and models that can be externally controlled with two power settings (VE) or remote controlled with three power settings (VT).

“SM” and “SP” are the codes for our Spot power heaters. Here, too, you can choose between external control with two power settings (SM) or remote control with three power settings (SP).

All HEATSCOPE heaters require very little maintenance. If they are correctly installed, the heating elements have a useful life of at least 10,000 hours of operation.

Because of its special design, the HEATSCOPE Zero features protection class IP-X4 when ceiling-mounted and IP-X0 when wall-mounted.

HEATSCOPE Vision and Spot carbon heaters feature IP protection class 44 irrespective of their installation type.

The first character of the IP class indicates the level of protection against small-parts penetration (X = no protection; 4 = protection against solid foreign particles with a diameter of 1 millimetre or larger). The second character indicates the level protection against water (0 = no protection; 4 = protection against splash water from all directions).

General operating costs of HEATSCOPE infrared heaters

Assuming an electricity rate of €0.35 per kilowatt-hour, the operating costs for HEATSCOPE heaters range from €0.56 per hour (HEATSCOPE Spot 1600 W) to €1.12 per hour (HEATSCOPE Vision 3200 W). For comparison, a much less efficient “mushroom-type” patio heater with 13 kW costs €4.55 per hour to run, i.e. four times as much as the most powerful and longest HEATSCOPE model.

Installing HEATSCOPE infrared radiant heaters

Because of their protection classes (IP44 for HEATSCOPE Vision and Spot; IPX4 or IPX0 for the HEATSCOPE Zero), HEATSCOPE infrared heaters may only be installed in covered environments. If you require a solution for an uncovered area, get in touch with us so that we can make a proposal for your particular situation.

HEATSCOPE Vision heaters and Spot heaters come with everything you need for a ceiling or wall installation: Installation brackets, hinge joints for continuous adjustment of the radiation angle, and optional extension rods for installations on flammable surfaces.

HEATSCOPE Zero heaters come with a few mounting brackets for ceiling installation on non-flammable surfaces. Other modules are optional, depending on your particular installation, such as hinge joints for aligning the heater angle, extension rods for suspended ceiling installation, or 45-degree mounting brackets.

With proper spacers, this is no problem. (HEATSCOPE Vision and Spot heaters already come with such spacers; for HEATSCOPE Zero heaters they are available as optional accessories.)

In most cases, your electrician will connect your HEATSCOPE infrared heaters directly to the house wiring via a separate circuit. The respective circuit is switched on/off with its own switch. Each heater must have its own fuse.

The best installation height depends on the type of heater, the environment and the amount of wind (see also “Technical information“).

HEATSCOPE ZERO no-light infrared heaters For enclosed areas with no wind, such as interior rooms, sunrooms or courtyards.
Recommended installation height: 2.1 to 2.3 metres (covered)

HEATSCOPE Vision infrared heaters: For semi-open areas such as protected patios or loggias with one open side.
Recommended installation height: 1.8 to 2.5 metres (covered)

HEATSCOPE SPOT infrared heaters: For open areas more prone to windy conditions, such as patios, balconies, smoking areas or outdoor seating areas in restaurants.
Recommended installation height: 1.8 to 3.5 metres (covered)

Just fill out our contact form. We will advise you on how many and what type of infrared radiant heaters work best for your needs. As a rule of thumb, you need roughly 150 to 400 watts per square metre of area to be heated – depending on the installation environment, wind conditions and installation height. We look forward to providing you with detailed advice.

General features of HEATSCOPE infrared heaters

HEATSCOPE ZERO heaters: On the basic model, the power connector is located on the left end of the heater. The included power cable (1.5 metres) is inserted into this connector.

If you want to hide the cable, you can move it to the back of the heater with the optional MHS-ESM connection element.

If you operate your heater with an MHS-FBM radio receiver, the power cable output will be automatically located on the back of the heater.

HEATSCOPE Vision and Spot heaters: For these models, the power cable is permanently attached to the device on the right, and a slightly slanted back side directly adjacent to the all-phase ON/OFF switch.

HEATSCOPE heaters are available in white and black.

HEATSCOPE Zero heaters are available with a black or white ceramic-coated, curved front panel; the body is always made of titanium-coloured aluminium.

HEATSCOPE Vision heaters are available with a black ceramic glass front and titanium-coloured body or a white ceramic glass front and a white body.

HEATSCOPE Spot heaters are available with a black segmented protective grid and titanium-coloured body or with a white segmented protective grid and a white body.

Unfortunately not. The ultra-heat-resistant cable is made of a special material. A white version would make it highly susceptible to discolourations from dust, dirt and exposure to weather.

Controlling HEATSCOPE infrared heaters

No. Because of their high power draw, infrared heaters cannot be controlled with a standard dimmer.

For HEATSCOPE Zero heaters we offer special radio modules and environmentally friendly battery-less EnOcean remote control solutions (ON/OFF, 100%, 80%, 66%). HEATSCOPE Vision and Spot heaters are available with an optional three-level remote control (ON/OFF, 100%, 80%, 50%).

No, you can control multiple heaters with a single remote control. With Zero heaters, this works by assigning different buttons on the remote control. With Vision and Spot heaters, you must point the remote control to the respective heater and change the setting upward or downward.

You can remotely turn the heaters on and off and control their power levels (Zero: ON/OFF, 100%, 80%, 66% – Vision & Spot: ON/OFF, 100%, 80%, 50%).

Shipping and delivery times
