The HeatAir 4G fully modulating LPG blown-air heater gives an impressive 4kW of heat output – but only when you need it. If you require a low output to maintain an already comfortable temperature then the HeatAir automatically detects what is needed and adjusts its output to suit. The inbuilt software detects what’s required to heat your living space to the desired temperature, and the heater will only select the most appropriate heat output and airflow to achieve this whilst maintaining maximum user comfort.
