  • Low noise fan heater
    Patent number: 7326883
    Abstract: A housing and a base formed integrally with the housing or attached thereto. An array of louvres is attached to or formed integrally with the housing. An electric motor-driven fan is located within the housing and blows air toward the louvres. An electric heating element is situated within the housing between the fan and the array of louvres. This avoids subjecting the fan to excessive heat of the heating element and reduces turbulence of airflow past the louvres, thereby reducing operational noise levels.
