How Does an Infrared Heater Work?

Last Updated: by Andrew S.

Infrared heaters nowadays are inspired by the first infrared heater—Mr. Sun—yes, Mr. Golden Sun. Generating infrared heat through combustion gases, Mr. Sun allows this heat to directly pass through space in order to send warm greetings (pun intended) to the surface of our planet. Cool, huh? That’s why even during cold days, we are still warmed by the heat that’s radiated by the sun through the air that surrounds us is cold.

Engineers then thought of how to recreate this process with the same effect. And voila! Infrared heaters were invented. These heaters can be considered as tiny, copycat suns. They burn fuel so they can generate heat. Thanks to the heat they produce which radiates downward, the people in the room, even the machines and tools, are warmed.

Usually, infrared heaters use propane or natural gas as fuel, though some use oil. By burning the fuel inside the unit, the hot temperatures are generated. It then heats the tube heater, one that’s steel or ceramic, inside the heater. The heat is them sent out in an infrared radiant energy form. The energy is released downward and warms the people or the objects below it.

Infrared heaters are cost-efficient but aren’t built to heat your entire house. Nah-ah. That’s a big no-no. They, however, have so many uses. They can be used for warming animals in veterinary clinics or zoos, coatings curing, plastic welding, plastic heating, plastic shrinking, glass and metal heat treating, and even for cooking!

These heaters are usually found in large spaces that need to prevent loss of heat. Airplane hangars, garages, and warehouses are usually the homes of infrared heaters. Their ability to keep areas from cooling too much makes them ideal for places that have large doors or doors that are frequently opened and closed.

Infrared heaters have a fast response time and can satisfy temperature gradients. They really are practical and convenient.

How should you use an infrared heater? Make sure you read your manual and place it somewhere high. Different manufacturers have distinct instructions and requirements, so you should really read your manual. If you have concerns, don’t be shy. Ask a qualified electrician for an advice. Installing should also be done by them since they can effectively and easily wire your infrared heater into your home’s or office’s existing circuits. You can even use it for your bathroom. An infrared heater can prevent damp and mold from existing. Remember, when you’re using your infrared heater, the panels installed should comply with the wiring regulations which specify distances between low voltage electrical appliances and water source. We wouldn’t want an accident to happen.
