An induction stove looks and cooks, a lot like a gas or electric stove, but it works a little differently. Gas and electric stoves work by using gas or electricity to heat the surface of the stove itself. Once the surface is hot, the surface then heats your cookware. The induction stove cuts out the middleman and heats the cookware directly.
It does this by harnessing the power of magnets to create an electromagnetic field. When you place your cookware on top of the stove it reacts with this field to create an electric current, which heats up the cookware, and ONLY the cookware, NOT the surface of the stove. Pretty cool huh!
Every year, more people are switching to induction stoves, and it’s easy to see why. Here are some of the biggest benefits of making the change.
Better For Your Wallet and the Environment: Induction stoves are the most energy-efficient stoves on the market. Unlike gas and electric stoves, they don’t waste energy heating the surface of the stove or the air around it. They just heat the cookware. That means lower bills for you and a lower impact on the planet.
No More Burns: Ever been burned by a hot stove? With an induction stove you’re not going to have that problem. Because an induction stove only heats up your cookware, the top of the stove stays nice and cool. We still wouldn’t recommend putting your hand on it, but it’s a lot safer, especially if you have kids.
A Cooler Kitchen: All that cooking can make the kitchen hot. Not with an induction stove! Gas and electric stoves don’t just heat the surface of the stove, they also heat the air around it. Induction stoves don’t. That means the kitchen stays nice and cool when you’re cooking. It’s just one reason that many restaurants are starting to make the switch.
Better Cooking: Unlike gas and electric stoves, induction stoves respond almost instantly to changes in temperature. That gives you way more control over your food, so you can cook your meal to perfection.
Induction stoves cook with the power of magnets, not gas, and when it comes to your health, that makes a big difference. Children living in households that use gas stoves for cooking are 42% more likely to have asthma than those that don’t. In fact, Gas stoves are believed to be responsible for 13% of childhood asthma cases in the United States. Studies have found gas stoves can release over 12 major pollutants, including nitrogen dioxide, methane and benzene, a chemical which may increase the risk of certain cancers and birth defects in people with long-term exposure. Here are some statistics to consider:
Induction stoves are gas-free and that’s a lot better for everyone.
Induction stoves will save you money in the long run, but there’s an up front cost to making the switch. Prices vary depending on, among other things, size, brand, and whether you’re getting a cook top or a full range.
A typical four-burner thirty-inch stove top usually costs between $950-$.
A full range, which includes an oven usually costs between $1,000-$4,500.
The Inflation Reduction Act allocates funding for states to offer credits of up to $840 for new induction stoves. If you’re switching from gas, you might be eligible for another $500 as well.
All together, that’s up to $1,340 off!
Depending on where you live, there are often incentives available at the state and local level, too.
Before any new purchase, you’re bound to have some questions. We’re here to answer any of them. Here are some of the most common ones we hear often:
Do I need special cookware?
Yes, but you probably already have it! Because induction stoves make heat using magnets, your cookware needs to be magnetic too. The good news is, most steel and iron cookware already is, although materials like aluminum and copper are not. An easy way to check is to put a fridge magnet on the bottom, if it sticks, you’re good to go, if it doesn’t, you’ll need to find something different.
Are induction stoves noisy?
Not really. Induction stoves can make a low humming or buzzing noise when in use. It’s usually quieter than the noise created by gas stoves and many people don’t even notice it. Some stoves are quieter than others and we can help you figure out which one is right for you.
Do I have to replace my whole oven?
For more Induction Heating Solutionsinformation, please contact us. We will provide professional answers.
No! It’s up to you. There are plenty of induction cooktops on the market that can replace your existing stove while keeping your oven as is. The cooktops are less expensive than a whole oven, and we can help you find a professional to install it.
Which brand should I get?
Choosing the right brand is important, and there are a lots to choose from. Induction stoves are growing in popularity so pretty much every appliance company has started making them. Fortunately, we’re here to help you pick the right one for you.
So here’s our recommendation: if you’re ready to switch stoves, induction is the way to go! You’ll save money, help the environment, and have a safer, better, healthier cooking experience.
Induction heating is a precise, repeatable, non-contact method for heating electrically-conductive materials like brass, aluminum, copper or steel or semiconducting materials like silicon carbide.

Solving Your Process Heating Problems
An induction heating system includes a special power supply which converts line power to a high frequency alternating current. This energy is delivered over a cable assembly to a workhead - or tank circuit - which creates an electromagnetic field within the attached coil. A work piece is placed in the coil, inducing a current, friction and heat in it.
Induction heating is used very effectively in many processes like brazing, soldering and shrink fitting, from something as small as a hypodermic needle to a large wheel on a military tank. Many companies in the automotive industry, medical device industry and aeronautics make efficient use of induction heating in their processes.
More about how it works:
If your work piece material is magnetic, such as carbon steel, it will be heated easily by induction’s two heating methods, eddy current and hysteretic heating. Hysteretic heating is very efficient up to the Curie temperature (for steel 600°C (°F)) when the magnetic permeability reduces to 1 and the eddy current is left to do the heating.
The relationship of the current flow in the work piece and the distance between the work piece and the induction coil is key; the closer the coil, the more current in the work piece.
But the distance between the coil and the work piece must first be optimized for the heating required and for practical work piece handling. Many factors in the induction heating system can be adjusted to match to the coil and optimize the coupling efficiency.
Heat losses and uneven, inconsistent application of heat result in increased scrap and diminished product quality, driving up per-unit costs and consuming profits. Best manufacturing economies are seen when the application of energy is controlled.
To bring a batch oven up to temperature and to hold the entire chamber at the required temperature for the process time demands much more energy than is required to process the parts. Flame-driven processes are inherently inefficient, losing heat to the surroundings. Electrical resistance heating can also result in the wasteful heating of surrounding materials. Applying only the energy needed to process your parts is ideal.
Induction selectively focuses energy only on the area of the part that you want to heat. Each part in a process enjoys the same efficient application of energy. Since the energy is transferred directly from the coil to a part, there is no intervening media like flame or air to skew the process.
The precision and repeatability of induction heating help to reduce process scrap rate and to improve throughput. The selective application of heat to the targeted area of a part enables very tight control of the heating process, also cutting the heating time and limiting energy requirements.
Read: Induction Heating is a Green Technology
Delivering the highest quality parts for the least expense in the least time is accomplished with an efficient process, in which the input elements of materials and energy are tightly and precisely controlled. Induction heating’s targeted application of heat to the part or an area of the part, as well as repeatability, provides the most uniform results for the least cost. Repeatability and throughput are two things that can be greatly improved with induction compared to resistance or flame heating.
Induction heating delivers savings primarily from significant reductions in process scrap rates, improved throughput and from the thrifty use of energy. There is no need for process ramp-up; heat is applied and stopped instantly. In comparison, batch heating in an oven requires an investment of time and energy that serves only the process, not the product. Throughput and efficiency are increased by induction heating with the careful application of energy (heat) in amounts no more than required by the product.
Any heating process carries a risk of operator contact with the heated materials. A technology like induction heating that limits the extent of operator-contacted surfaces does reduce the overall risk. If heating can be limited to only the part and further limited to a zone of the part, safety is improved even more.
