What are Heat Diffusers?
A heat diffuser is a cooking utensil that sits on top of either gas stoves or induction plates. The heat diffuser regulates temperature and shields pots from direct heat.
A heat diffuser for a gas top stove diffuses heat by passing it through multiple perforations. This increases the area of effect and directs the heat into multiple places around a surface instead of just one place.
Benefits Of Heat Diffusers
Here are some of the major benefits of using heat diffusers.
- They are placed over the induction plate to shield both the glass surface and the pot.
- A heat diffuser is a great option when you want to protect your cooking range from scratches and you don’t want the pot to be exposed to a lot of heat.
- It increases the life of the cooking range.
- In the case of an induction plate, it effectively transfers heat to and from the induction plate to any other plate.
How To Use A Heat Diffuser
It’s very easy to use a heat diffuser. You just need to just put it on your gas top stove or over the induction area when the stove is off. After that align the heat diffuser with the burner in case of the glass top or with the induction area in case of an induction cooktop.
Once the diffuser is placed, put the pot on the diffuser, crank up the heat and wait for it to get hot. The heat will transfer from the heating element, through the glass to the diffuser where it will distribute evenly and then finally transfer into the pot. Now you are ready to cook your favorite dish.
Types of Heat Diffusers
There are several types of heat diffusers for glass stoves available. While every type of heat diffuser may work with your cooking range, you may benefit more if you select the right diffuser.
Heat diffusers are available in a variety of sizes, dimensions, and forms. Some are made of solid material and have a grip, while others just have circular surfaces that can be placed and removed from the stove once it’s cooled.
There are even diffusers that look like gas top diffusers. They have small vents that let the flame exit and transfer heat more efficiently.

Here is what you need to look out for while selecting a heat diffuser for your glass-top stove:
- Build Quality
- Design
- Size
Build Quality
A heat diffuser is only effective when it’s made using high-quality materials. Materials like stainless steel, cast iron, or aluminized steel are the best choice for efficiently transferring heat from the surface of the glass top to any other pot.
Further, the high-quality diffusers are designed to stay on the glass top indefinitely, which means that you can put them over the glass top once and then forget about it.
An easy way to check whether a heat diffuser is made of high-quality materials is by inspecting it after subjecting the diffuser to maximum heat for at least 15-25 minutes or longer.
Design
A plain surface design with medium thickness is excellent when you want to regulate heat. This comes in handy when cooking with liquids that are prone to boil-over. However, if you are looking for a heat diffuser for everyday cooking then you can go with a thing and perforated design.
Size
The size of the diffuser is also important. A smaller diffuser on a larger induction surface will result in energy and heat loss. The best way to avoid this issue is to proactively plan and take measurements for your cooking range before purchasing the heat diffuser.
Although most manufacturers make universally sized heat diffuser tops, it is recommended that you purchase a diffuser that is specifically sized for your glass stove for maximum heat transfer.
