What to look for, and a little bit more on the topic

We find a lot of people may not necessarily be interested in this aspect of the article. Some people simply come to this website and look at the recommendations that we are giving, and that is enough for them. That is great, if that’s the case! However, we also want to give you a little bit of a better understanding of the different situations that may be calling for you to use a heat diffuser. After all, you don’t want stovetop scorching, right?

Yes, we thought so. 

While having a powerful gas stove can be nice in a lot of situations, there are also reasons why it may be incredibly impractical. It may not always be possible to correctly adjust the gas with the precision required for the gastronomical wonder you’re working on. If you’ve previously experienced that you will try adjusting the heat of the flame simply to find yourself with no flame at all because it went out, that’s where the heat diffuser comes in handy. As you’re turning the nob, you’re managing to approach the amount of flame that you’re hoping to get out of it, but then suddenly the fire goes out – dang!

If you are preparing things in some sort of container that may not be able to handle as much direct heat as the gas flame offers, you will want to distribute the heat across a larger surface area. There are also certain types of foods where a gas flame may not be ideal, which, for instance, could be things like caramel. If you’re making caramel but not properly distributing the heat, you will see it burn, very fast. The heat diffusers act against this very easily and give you the results you’ve been looking for! 

However, there are various different things where the  food itself may call for you using this handy little tool as you’d otherwise burn it, or because you may be working with a tool unable to handle such amount of heat. Several recipes call for low-heat settings, like when you’re heating up milk, which in turn also makes sure that you’re not ending up with boiling milk all over the place, but it can also be a great thing for warming coffee or toasting flatbreads.

The weight & material

The weight of the actual object is something that you should look for. You may have your own preferences on whether or not you want it to be light or heavy. Other preferences that kitchen connoisseurs talk about is the type of material that you will use. It’s important to note that if you have kids, or if you feel like you’re a little bit distracted, you may not be willing to get a type of material that tends to keep heat for a long time, such as cast iron, whereas you’d be better off with a thinner, less dense material that loses heat quicker.


Heat diffusers are a great way to protect your cookware and glass tops form damage and burns. Although they do not offer permanent solutions, they are a great way to use old and heavy cookware on your newly acquired glass cooktop or gas stove. If you are overwhelmed by the choices available, we hope that this article helps you to narrow down the list.
