Noirot Panel heaters are approved by the National Asthma Council Australia. Noirot make heating more efficient, effective and safe by taking advantage of the natural process of convection. The optional Easy Glide Castors allow you to take the warmth with you wherever you go. All Noirot Panel and Spot Plus heaters are all wall mountable and portable. All Spot Plus heaters are fitted with a thermal safety cut-out and have rounded edges for safety. The lack of fan also means these heaters are ideal for asthma sufferers. This means the air naturally circulates over the Monobloc elements to push warm air back into the room and stops nasty dirt and dust particles circulating the air.?
