Frequently Asked Questions / About the Product
Are Prestyl panels durable products or will the intensity of the IR-light diminish after a certain time? Can the wavelength of the IR-light alter?
No, the thin-film heating medium in Prestyl’s panels was developed for aircraft and passenger train car use. Aging train cars are often sold to third world countries and their heaters are expected to work for 35-50 years. Hence, in theory the Panels should last for many generations; the film has been in use and tested extensively for over 16 years; the products are not subject to wear and tear even when used intensively. The IR is determined by the proprietary thin-film and its wavelength cannot change with age.
Do you test every panel that leaves the production facility extensively?
Yes, we produce our panels according to the “Quality at the source” concept; every panel is tested. We guarantee the quality of our product.
Have you encountered any technical difficulties so far? What sort of technical trouble can I expect?
The only known technical problems were due to incorrect sizing, ignored building problems (water seeping into the slab, un-insulated slab for instance) and poor installations. There should be no technical problems as long as the basic guidelines are followed. If the product is installed as a system (panel, power supply, relays, and thermostat), the building is suitable for IR, and the transmission (sizing) calculator is followed there should not be any issues.
Can I decorate the Panels myself?
Prestyl’s panels are powder-coated and baked during the manufacturing process. The artworks are printed with high-quality UV- curable inks. Prestyl will not guarantee the performance of paint supplied by third parties as damage may occur. With the many changes in paints due to ROHS and other compliance issues we found that many paints can have a negative effect on the transmission of far-infrared. Hence, we do not recommend painting or decorating and will not honor any warranty or resulting liabilities.
We do offer custom (solid) colors and printing options. There is an additional artwork and handling charge and it may take up to two (2) months depending on the printer backlog.
What does “Prestyl’s Radiant Artworks keep conditions homogeneous” mean?
It means that Prestyl’s Far-Infrared heating products, in addition to creating “temperature stable” surroundings, also keeps the humidity in a room at a stable level (we do not use the air as a medium to transport warmth).
What is the ideal air humidity?
A level of 40 to 50% air humidity is ideal for humans and animals.
When the sun shines I can feel its “infrared-light” shining right through windows? What about the reverse, energy losses when we use Prestyl?
Yes, a certain amount of IR-light passes through windows; the amount of Infrared that penetrates windows is dependent on its wavelength.
The sun contains light (both visible and invisible) in the entire electromagnetic spectrum; much of this light comes through the windows but only the IR portion gets stored in the objects, walls and floors. In return these objects “convert” the energy into far-infrared heat. Once converted, only a very small amount of far-infrared will be allowed through the glass; most is reflected back into the room (we compensate for this by using a “correction factor”).
If I place my Panel on the ceiling will it mainly heat my head?
No, the panels emit far-infrared light which heats the walls, floor and objects; the resulting heat is distributed equally through a room. In fact, in a properly setup system, you cannot tell where the heat is coming from.
Can I get burned briefly touching a heated panel?
No, the operating temperatures (around 200 degrees F or 95 degrees C) are deemed to be safe to the tough by the regulating agencies (UL, ETL, CSA, European and other local regulators around the world). These agencies assume that the touch is brief and that there is no prolonged contact with the heated surface. The temperatures are comparable with the outside of a cup of hot coffee or tea. After touching the hot surface you would naturally pull away.
The cold period for my area only represents a very short period of time. Can I leave it out when calculating my climate factor?
No, the lowest temperature of the year is a defining element in your “climate factor”. If you ignore this and you have several cold days in a row, your system will slowly lose its ability to keep up and won’t “work properly” until the outside temperature exceeds the design temperature once more.
How do I clean my panel?
During the cleaning process, always clean the heating panel while at room temperature. Remove the power cord from the electrical outlet. Wipe with a damp cloth or use a glass cleaner, being sure not to allow moisture to drip into the panel.
