Are all stove tops created equal?

Are all stove tops created equal?

The kitchen is the center of any home, and the stove is a crucial component to a successful kitchen. Determining which type of stove to purchase can be a big decision. There are several stove cooktop options available, each with its own unique benefits. Learning the basics of each stove type can help you determine what works best for your needs.

One of the most common stove tops available to consumers is the electric stove top. This stove top uses electricity to heat the element on the stove top, composed of either radiant heat coils or a glass surface. That heat is then transferred to the pan, pot, or other cookware. Electric stove tops with heat coils are relatively durable and can be scrubbed without having to worry about causing much damage. For electric stove tops with a glass surface, cleanup is easy; however, users should be careful not to scratch the glass. Electric stove tops have a moderate energy efficiency rating, where roughly 74% of the heat reaches the food; however, electric-coil stove tops are slightly less efficient than glass.

Another common stove top option is the gas-powered stove top, where the flames can be produced using either natural gas or liquid propane. Many cooking enthusiasts prefer gas because of the instant heat and ability to control temperatures more easily. In the rare case of power outages, gas stove tops will still function while electric stove tops will not. However, gas stove tops are the least energy-efficient, with about 40% of the heat generated reaching the food. Much of the energy from gas is lost in the air and wasted as lost heat. It is also important to be careful of the potential safety risks associated with gas stove tops, such as burns, impacts to indoor air quality and gas leaks.

Although less common, the induction stove top is quickly gaining popularity. An induction stove top uses electromagnetic heating technology to heat the cookware. Only specific cookware can be used on an induction stove top. The cookware needs iron to react properly with the stove top, which makes stainless steel, cast iron, or carbon steel excellent cookware options for induction stove tops. Underneath an induction stove top is a metal coil that creates a magnetic field, which reacts with the cookware through an electrical current, generating heat. The induction technology works quickly to heat food and is even faster than gas stove tops. Through the induction process, only the part of the stove top directly touching the cookware becomes heated, while the rest of the stove top stays cool.

One of the best benefits of an induction stove top is safety; there are no open flames and the stove top itself is cool to the touch, making burns much less likely. Induction stove tops are also the most energy-efficient form of stove top cooking, with an energy efficiency rating of about 90%, so most of the energy goes to heating the cookware and not the surrounding air. Induction stove tops, like glass electric stove tops, are also easy to clean because of the smooth surface. Despite all these benefits, induction stove tops can be quite expensive — more so than gas or electric stove tops.
