To start with, we will define a heat diffuser. It is a round and flat object made of metal. It is placed on a stove burner to help reduce the intensity, or amount of heat that will reach the bottom of a pot or pan. It also helps to improve the distribution of heat on the pan. You should place it on the burner, then place the pan on top. It works perfectly with electric and gas stoves. If you have a gas stove burner, this is the perfect tool for you. The reason for that is that the flame of some stove burners will go out when lowered too much.

The main problem that most of us face is finding a heat diffuser that is perfect for our gas stoves. That is why we researched and created this post to help you identify the most efficient stovetop diffusers for your kitchen.

Considerations to Make When Buying a Heat Diffuser

Before you purchase a gas stove diffuser, make sure that you think of the following features.


Different materials on a heat diffuser will work differently. The material used to create a heat diffuser will also affect factors such as cleaning and the level of heat that will reach your pan. The durability of the pan also depends on the type of metal used to create it. There are heat diffusers that are made using cast iron, while some are made using stainless steel, and so on, as you will see in the reviews below. Make sure you know more about the type of metal used on the diffuser before you purchase it.


There are different sizes of heat diffusers. The size of the heat diffuser you require will depend on the size of your burner. As you will see, there are some diffusers made to fit large burners, while some will work better on small burners. Consider your stove burner’s size before you settle on a certain type of burner. The size of the heat diffuser will also restrict the size of the pot or the frying pan that you can cook with. If you place a large pot on a small diffuser, for instance, the distribution of heat will not be even to the entire pot.


Some companies will restrict you from washing the diffuser with your hands using soap and water. Some of the heat diffusers, on the other hand, are dishwasher safe to make cleaning easier.

How Does a Heat Diffuser Work?              

If you own a powerful gas stove, you know how impossible it is to set the flame to a lower setting. The stove seems to have two main settings, which are extremely hot, or completely off. If you turn the knob to lower the fire, you will notice that it will usually flicker, after which it burns out before you achieve the adequate amount of heat. There are recipes and certain types of foods that require low heat for a longer period to cook to perfection. For people with a gas stove, perfecting these meals seems like an impossible task. If you have a gas stove and you want more control over your cooking, then all you need to gain control over your flame is a heat diffuser.

Heat diffusers are mostly used in most commercial kitchens. The main purpose of a heat diffuser is to absorb the heat produced by the flame of a gas stove and distribute it evenly and constantly to the utensil you are using to cook. This aspect really comes in handy if you want to improve your meals by controlling your flame. Therefore, you can keep the flame at a lower setting, which will help you achieve perfect temperature especially if you are cooking grains that absorb heat. For instance, when cooking oatmeal or rice, you will not have to deal with a layer of scorched rice at the bottom of your pot.

If you want to warm coffee and you do not have a coffeemaker, you can keep it at a hot temperature by using a heat diffuser placed on a stove with a low flame. Additionally, you can warm a tortilla without scorching it a beat by using a heat diffuser. The direct flame will not scorch your tortilla.

How to Use a Stove Top Heat Diffuser

Heat diffusers are especially important in improving the even distribution of heat. However, they have one more advantage, which is to protect your cookware from direct heat. They are also effective in protecting your stovetop from hard cookware such as cast iron cookware, especially if you are using a glass cooktop. The diffuser will be your stovetop protector since it will provide a physical barrier between the cookware and the stove. When you have no physical contact between the cooktop and cookware, there is no need to worry about the rough bottom of the cookware or unsafe material. Any damage that might occur will be between the cookware and diffuser.

It is important that you refrain from using unnecessary levels of heat when you are cooking with your diffuser. It is also important to avoid heating your diffuser when there is nothing on top of it because it would damage the diffuser. As long as the diffuser has a pot or pan to which it will transfer heat, everything will be okay.

All you need to do is place the diffuser on the cooktop and place a pot, pan, comal pan, or Aebleskiver Pan on the diffuser, after which you should turn on the flame. You should know that these diffusers are not necessary when you are using a stove that will distribute heat evenly unless your main worry is damaging the stovetop.


The best heat diffuser for a gas stove will depend on your personal preferences. You should check the performance of different metals in regard to the distribution of heat and ensure that you check the reviews and comments from previous buyers. You should also consider how safe it is to use a certain type of heat diffuser before you purchase it.
