The Convector heater warm the room as it passes over a heated coil; some use a fan to forced in the cool air to heat. The heated air rises naturally or is forced out by a fan and spreads into the space to warm room.
A convection heater is a type of heater that uses convection currents to heat and circulate air. These currents circulate throughout the body of the appliance and across its heating element.
Convector heater including glass convection heater, Metal Convection Heater, also mini convector heater can be a Frost Heater.
