What is infrared heating? Is it safe?
KELVIN works through far infrared radiant heat. Rather than heating the air, far infrared radiant heats you and the object in your room directly. Its best compared to the warmth of the sun, which warms you regardless of the temperature of the air around you. The opposite to Radiant heat is convection heat. Convection heaters heat air, which retains heat poorly and disappears on draughts. Far infrared heating is completely safe and has been used by people in their homes for decades.
What safety standards do KELVIN heater adhere to?
Kelvin meets the highest European safety standards and is certified to the EN 60335-2-30 and EN 60335-1 standards. Moreover, all Kelvin models have an IP44 rating allowing them to be used safely in bathrooms and kitchens, where resistance to water splashes and moisture is needed. KELVIN also complies with the more recent EU Lot 20 Legislation around heating efficiency.
