Convection Heater a device that works by filling a room with warm air. Fan heaters and ducted heaters are examples of convection heaters.
Convection heaters heat the air and get the air circulating throughout the area being heated by allowing hot air to escape at the top of the heater thus sucking cooler air in at the bottom of the unit, heating it and letting it pass out of the top. The smaller ones run from 20 lb propane cylinders while the largest model puts out so much heat that a higher propane flow is given by a 100 lb tank. These are construction grade heaters and are not suitable for home use.
Great for industrial spaces and large rooms, Convection Heaters offer natural ventilation. By heating up and replacing cold air, these heaters quickly warm up their surrounding area. Convection Heaters are often quieter in operation compared to traditional fan heaters.
In a convection heater, the heating element heats the air next to it by conduction. Hot air is less dense than cool air, so it rises due to buoyancy, allowing more cool air to flow in to take its place. This 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. They operate silently and have the lowest risk of ignition hazard in the event that they make unintended contact with furnishings. This is a good choice for long periods of time or if left unattended. They are very safe heaters and there is a very low chance of getting burned.
