Hot fan heater
This heater can be set between 1° and 37° to heat a room. When it hits the desired temperature, it shuts itself down. If a drop is detected, the heater turns on to maintain the set temperature.
Air is drawn in through a mixed flow impeller. It is then accelerated througha 2.5mm aperture set within the loop amplifier. This creates a jet of hot air which passes over an airfoil-shaped ramp channeling its direction. Surrounding air is drawn into the airflow, amplifying it 6 times.
