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. 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. Additionally, the Noirot Precision Thermostat ensure that your room always maintains the desired temperature within 0.1 degree Celsius and prevents the room from getting too hot or too cold, stopping any aggravation.
