Quality & Safety

There have been a number of low voltage, very thin, carbon based heating products in the form of “Wallpaper”, in-wall, ceiling or underfloor mats that have recently appeared on the market promoting themselves as “Infrared”, “far infrared” and / or “Radiant” heating technologies. Typically these systems are low voltage (via…Read more

Herschel Far Infrared emits the biologically most significant Comfort Heating wavelengths because skin content is 80% water which absorbs heat most efficiently from wavelengths of 3 microns and lower (Far Infrared). Far Infrared is better absorbed by the skin, is less transmissive (passes through) and is less reflected. Infrared wavelengths…Read more

Herschel heaters can deliver energy-savings up to 60% over traditional heating systems. Providing warmth 24×7 at a fraction of the cost of gas, oil, or other electric heating, infrared warms the fabric of the building – and not the air – which is the key to its energy efficiency. 100%…Read more
