To understand how they work, it’s important to understand what is infrared heat.
Infrared heat is radiant heat which is the most basic form of heating known to man. Infrared heat creates a feeling similar to the warmth you get on your face from the sun heat. It is similar to the heat that your own body emits. Infrared heat works by heating objects, which then radiate the heat back and keep warm the environment around you. Unlike other types of heaters, radiant types do not heat air, but rather objects. Convection heaters heat the air, but it holds the heat very little, so the warmth rapidly disperses.
Infrared light stays beyond the spectrum that we can see, so it stays invisible to the eye. The far infrared spectrum in which infrared heaters operate produce heat that is tuned to the range of 9 to 14 micron meters. This range ensures that this type of heating is safe and healthy. These heaters send electromagnetic waves. When they touch a surface, the molecules oscillate and the heat energy is released into the heated environment. That energy excites the molecules of heated object so the object starts to vibrate and gain energy, consequently warming up. Far infrared is especially well absorbed by water, and our skin are 80{43604990ff6c183ee8cd13241e5eb6af80212155a6e62f6c701831b1aebac506} consist of water. So our bodies well absorb the far infrared.
Traditional heating systems that heat the air in the room, push the warm air up allowing it to gather at the ceiling. Infrared heaters are considered more energy efficient as they lock the heat in the objects which then slowly release the pleasant warmth into the surrounding environment. Heat waves bounces off the surfaces of objects and that makes all the objects around you, and including you, absorb the heat.
They do not the cause dry air. They also prevent heat loss as there’s no ventilation process included in the operation. Infrared heaters come with different specifications. They can use different sources of power, such as gas, propane or electricity. The specifications can also include different maximum operation temperatures and heat outputs. Some other features that differ from model to model include timers, filters, controls, thermostat, fan, wheels, color and other.
