An electric heater is an electrical appliance that converts electrical energy into heat. Radiative heaters or "space heaters" directly warms people and objects in the room, rather than warming the air. This style of heater is most useful in an area that is unable to be kept with minimal airflow. They are also ideal for basements and garages since they are good at spot heating. They are an excellent choice for task specific heating. Convection heaters sets up a constant current of hot air that leaves the appliance through vent holes and heats up the surrounding space. They are ideally suited for heating a closed space. A fan heater is a variety of convection heater that includes an electric fan to speed up the airflow. This reduces the thermal resistance between the heating element and the surroundings, allowing heat to be transferred more quickly. This is a good choice for quick heating of closed spaces however they should not be left unattended. Goodman's carries a variety of Delonghi heaters.
