How Infrared Heaters Work
Every warm object gives off infrared radiation. An infrared heater simply produces a lot of it, in a controlled direction.
Radiation, convection and conduction
Heat moves in three ways:
- Conduction – through direct contact, like a hand on a warm mug.
- Convection – carried by moving air or water, like a furnace or baseboard.
- Radiation – as electromagnetic waves that travel through the air, like sunlight.
Infrared heaters rely mainly on radiation.
Inside the heater
An electric infrared heater passes current through an element made of materials such as a tungsten filament, carbon fibre or a metal-sheathed coil. The element gets hot and emits infrared energy. A polished reflector behind it directs that energy forward.
Gas infrared heaters burn propane or natural gas to heat a ceramic or metal emitter, which then radiates heat in the same way.
What you feel
When the infrared energy reaches you, the floor or furniture, it is absorbed and turns into warmth. Because the air does not need to warm up first, you notice the heat quickly, and it is less affected by drafts.
Why placement matters
Infrared heat travels in straight lines. Point the heater at the area where people sit or work, mount it at the height the manual recommends, and avoid obstructions between the heater and the people it is meant to warm.
