Stone radiators - Luxury radiators - Art radiators! Stone radiators are the real alternative to steel, aluminium and cast iron radiators. The stone is crushed before being reformed into a unique material to provide an exceptional diffusion of thermal energy. The exceptional features of our radiators made of natural stone include the emission of evenly distributed radiant heat. Due to the unique diffusion of thermal energy in the natural stone the radiators have exceptional heat retention properties. This way there is less energy expenditure than in the case of traditional radiators. Our stone radiators, due to their large surface, emit soft and homogeneous heat at low temperatures as well.
