    What’s far infrared?

    The core feature of every Sundirect heater is the far infrared heating element. It works the same way as a classic stove being a body with higher temperature which transfers energy to a body with lower temperature through electromagnetic radiation. We mainly consider three different types of infrared: Near infrared, Medium-wave infrared and Far infrared. Normally Near infrared heaters operate at high filament temperatures above 1,800 °C, Medium-wave infrared heaters operate at filament temperatures of around 1,000 °C and Far infrared heaters operate at a much lower temperature of approx 80°C to 120°C. Due to this core advantage, the Far infrared technology is widely used in the Far infrared sauna, Infrared lamps and other appliances for health treatment systems as well as in the panel heaters like those supplied by SUNDIRECT. Because the heating elements are at a relatively low temperature, SUNDIRECT heaters do not yield emissions, dust, dirt, formaldehyde, toxic fumes from paint-coating, etc. This has made SUNDIRECT heaters very popular among people with severe allergies and multiple chemical sensitivity. Several studies have examined the use of far infrared heater in the treatment of chronic health problems, such as high blood pressure, congestive heart failure and rheumatoid arthritis, and found some evidence of benefit.

    Comfortable Heating

    Infrared panel heaters emit a very high ratio of heat as radiant heat. This is on the same wavelength as the healthiest rays from the sun. Infrared panels heat objects directly, rather than warming the air (which is what convection heat does), and thus creates the best and cosiest feeling warmth for you. Compared with convection heaters, there is no air circulation, and therefore no dust circulation. The air does not dry out when using infrared panel heaters creating a clean and healthy room climate.

    Energy Saving

    Infrared heaters directly heat objects or bodies in range, meaning the heat is stored much longer which results in energy savings.
    Using a heater with thermostat, once the desired room temperature is reached, the heater will turn off automatically!


    SUNDIRECT fully respects the international environment policy, using all the material that is lead free (ROHS, REACH certificate). We highly recommend our customers use their infrared heaters combined with a wind generation or photovoltaic system to create a low carbon footprint.

    Sundirect promises quality

    Sundirect offers the highest quality panel heaters available on the market, every production process is well designed and all panels are carefully checked before leaving the factory.
    The in-house produced carbon crystal heating element
    Among all the parts that decide the quality and the lifespan of the panels, the heating element makes a significant difference. We can guarantee it’s quality by producing the heating element in-house. Compared to our competitors using the carbon fiber heating element we offer a unique version of carbon crystals. We use german technologies for the production of carbon crystals, which is an upgraded version of carbon fiber. It removes the problem of hot spots and creates a more even surface temperature (within 10 degrees). By adding special chemical materials into the ink generating heat, the Sundirect carbon crystal heating element even further enhances the performance especially when operating around the working temperature of about 100 degrees.

    Better design, better effiiciency

    The design of a panel is very important regarding its efficiency. We use a white aluminium or glass/ mirror surface above the heating element to round up the design. All Sundirect panels use a heating element, insulation material and a reflection layer. Most competitors are not using insulation materials due to easier production steps while this is one of the most important factors when it comes to design. We use a fiber glass insulation inside the panel with a thickness of 3mm which decreases the loss of energy, thus resulting into energy savings making our panels 7-8% more efficient.
