Infrared BBQs FAQs
Q: What is the difference between conduction, convection, and radiation. And how do these types of heat transfer relate to an infrared BBQ?
A: Infrared BBQs are so efficient because they greatly utilize radiation, but convection and conduction also take place. Electric coils beneath a transparent ceramic or glass surface emit electromagnetic radiation (in the form of visible and infrared light) which heats the food. Of course, some of the heat from the coils is absorbed by the ceramic or glass surface, and any food atop of it is also cooked via conduction and convection (conduction where the surface and the food are in contact, convection where they are not).All forms of grilling actually use a combination of conduction, convection, and radiation – it’s just that different types of cooking and grilling favor one type of heat transfer over another.
Q: Why have infrared grills become so much more affordable in recent years?
A: While infrared grills have been used for decades, they have mostly been used in restaurants, partly due to the expense. Of course, more recently, the price of an infrared BBQ has dropped, making one more affordable for basic homeowners. One reason for the drop in price is the drop of a patent.TEC was the original and sole manufacturer of infrared BBQs, but their patent expired in 2000. Since then, more grill manufacturers have started to make the BBQs and as competition and technology have increased, the prices have decreased.
Q: Which type of grill should I get?
A: The answer to this question depends entirely on your preferences, budget, and location. If you live in a cold weather climate or plan to grill during the winter, then an infrared BBQ may be your best bet. It will grill well and grill quickly, even at low temperatures. If you like the taste of charcoal, then stick with it. If you want an inexpensive grill, then you may want to stray from getting an infrared BBQ. For some people, a sort of hybrid is the best bet – a natural gas grill with an infrared rotisserie, for instance.
