Convection heaters also referred to as convector heaters or simply convectors, are non-fan forced heaters that utilize natural convection to deliver the heated air back into your conditioned space.
- This feature makes the HVAC system much quieter compared to standard fan heaters.
Since it doesn’t use a fan to blow air, the convection heaters provide a great solution to lessening the circulation of pollen and dust, improving the indoor air quality and, in turn, the quality of living. Tapping into a natural phenomenon referred to as convection, the air inside the convector is heated, making it less dense than your cool ambient air, enabling it to rise because of buoyancy. While the heated air rises, your surrounding cooler air is pulled into your convector, establishing a constant flow. If you put your convector under a window, the rising heated air will block the downdraft of cold air, forming a heated air curtain. Each convection heater comprises two components that function together to effectively deliver heated air into your home: the over-temperature limit and element. The element transforms electrical energy into heat by passing an electric current through a specially designed resistance wire. The elements used in convection HVAC systems include a metal sheath made of a spiral wound resistance wire covered in an insulating powder. On the other hand, over-temperature limits are devices designed to sense temperatures and are located on or near the element to halt the flow of electricity to your element in case an abnormally hot condition happens. In convection heating systems, the over-temperature limit device is typically activated when an air discharge opening or inlet is blocked by furniture or drapery, causing heat to build up.
