Transforming Your Electric Cooktop To Induction: A Diy Guide

how to convert electric cooktop to induction

Converting an electric cooktop to induction can be a complicated process. While it is possible to retrofit an electric stovetop with induction burners, it is not a straightforward task and may require significant electrical upgrades. Induction cooktops heat pots and pans with magnetic fields, and older electric stoves used electro-mechanical potentiometer/rheostat burner controls, which are very different from the digital microprocessor controls used by induction burners. This means that you would need to replace the old control systems and wiring, and assemble a new set of microprocessor-driven control boards. Furthermore, induction cooktops require a dedicated, grounded 240-volt circuit with 40- or 50-amp breakers, which may necessitate running a new, bigger cable to the cooktop. However, low-current induction cooktops are an emerging solution that can address many of these issues, as they typically require less electrical power and can work with existing wiring and kitchen appliances.

Consult an electrician

If you are considering converting your electric cooktop to an induction cooktop, it is highly recommended that you consult a licensed electrician. They will be able to assess your home's existing electrical service and determine if it can support an induction cooktop. This is especially important as induction cooktops require a dedicated, grounded 240-volt circuit with 40- or 50-amp breakers, and the wiring process can be complex.

In some cases, you may need to run a new, bigger cable to the cooktop as induction cooktops draw significantly more current. An electrician will be able to advise you on the necessary electrical upgrades and ensure that your home's electrical system can handle the demands of an induction cooktop. They will also be able to provide guidance on the optimal location of the junction box, which can vary depending on the power supply cable's feed direction.

If you are installing an induction cooktop in a new location, it is crucial to have a professional electrician assess your home's electrical system before purchasing the cooktop. This will ensure that you select an appropriate cooktop that can be properly supported by your home's electrical service. Additionally, an electrician can guide you in choosing a cooktop that aligns with the manufacturer's specifications, including the required amperage, to ensure a safe and proper installation.

Even if you are simply swapping out an old electric cooktop with a new induction unit of similar size and power, it is still advisable to consult an electrician. They can verify if the existing circuit and receptacle will work without modifications and ensure that the existing circuit breaker has an adequate rating to handle the induction cooktop's requirements. This will help prevent any electrical issues or safety hazards that may arise from improper installation.

When hiring an electrician, it is important to choose a licensed professional who has experience with induction cooktop installations. They should be able to provide you with a certificate of electrical safety upon completion of the work. By consulting an electrician, you can ensure that your conversion to an induction cooktop is done safely, effectively, and in compliance with local codes and regulations.

Check your current capacity

Before installing an induction cooktop, it is important to check your current electrical capacity to ensure it can support the appliance. Induction cooktops require more power than traditional electric stoves, so you may need to upgrade your electrical service.

To check your current capacity, start by locating your switchboard. Look for a circuit breaker marked "cooktop", "stove", or something similar. There should be a number on it, such as 20, 25, 32, or 40. This indicates the size of the breaker.

If your new induction cooktop requires less power than the breaker size, you may not need to re-run any cabling. However, if your cooktop requires more power, you will need to run a new, bigger cable to the cooktop. This is because induction cooktops draw significantly more current, and you don't want to overload your electrical system or blow a fuse.

It is recommended to consult a licensed electrician to determine whether your home's electrical service can support an induction cooktop and to perform any necessary wiring. They will be able to assess your current capacity and make any necessary upgrades to ensure a safe and proper installation.

Additionally, keep in mind that some induction cooktops require a dedicated, grounded 240-volt circuit protected by 40- or 50-amp breakers. Always refer to the manufacturer's specifications and recommendations to ensure your electrical system can handle the load.

Use an induction converter disk

Converter discs, also known as induction adaptor plates, can be used to convert an electric cooktop to induction. These metal plates, often made from stainless steel, are placed on an induction cooktop to enable the use of cookware that would otherwise be incompatible. This can be particularly useful if you have recently invested in an induction cooktop but wish to continue using your old, non-compatible cookware.

However, there are several drawbacks to using converter discs. Firstly, they can negatively affect the electronics of the induction cooktop due to the high temperatures required for their functioning. This can lead to reduced efficiency and even damage to the cooktop. Additionally, converter discs may result in reduced pan responsiveness and uneven heating, with hotspots developing in certain areas.

Furthermore, using converter discs defeats the purpose of upgrading to an induction cooktop, which offers advantages such as energy efficiency, fast heating, and safety. Induction cooktops create an electromagnetic field to directly heat the cookware, while electric cooktops simply create a hot surface.

While converter discs may extend the life of your cookware, it is recommended to follow the manufacturer's guidelines and use the induction cooktop as intended to ensure optimal performance and longevity. If you have induction-incompatible cookware that you wish to continue using, alternative solutions include purchasing a portable butane stove or a portable electric resistance coil stove.

Install a low-current induction cooktop

Installing a low-current induction cooktop can be a great way to upgrade your kitchen without a complicated or costly process. Low-current induction cooktops, such as those from Fisher & Paykel, offer a solution to common challenges associated with the switch, including the need for electrical upgrades, high installation costs, and compatibility with cookware. Here are some steps and considerations to help you install a low-current induction cooktop:

Planning the Installation

Before purchasing a low-current induction cooktop, it's essential to plan the installation process. Measure the width and height of the space where you intend to place the cooktop, ensuring that it will fit properly. Mainstream models typically come in nominal sizes of 30 inches and 36 inches. If you're replacing an existing cooktop, choosing a new one with the same make and size can minimise the adjustments needed for the countertop cutout. Additionally, check the manufacturer's installation specifications for ventilation requirements, as these cooktops need space underneath for proper airflow.

Electrical Considerations

Low-current induction cooktops generally require less electrical capacity than traditional induction cooktops, making them ideal for smaller spaces like apartments. However, it's crucial to consult a licensed electrician to determine whether your home's existing electrical service can support the appliance. They will assess if any electrical upgrades are necessary, such as ensuring adequate amperage and circuit rating.

Compatibility with Cookware

One of the benefits of low-current induction cooktops is their compatibility with a wider variety of cookware. Induction cooktops typically require magnetic cookware, such as cast iron or magnetic stainless steel pots and pans. However, low-current models may be more forgiving, allowing you to use your existing cookware without needing to replace it.

Installation Process

Once you have selected a compatible low-current induction cooktop and ensured your electrical setup can accommodate it, you can proceed with the installation. This process typically involves connecting the cooktop to your home's wiring at the junction box. Most manufacturers supply a flexible armoured cable for this purpose, but it's recommended to seek input from a licensed electrician due to potential variables in existing wiring and local codes.

Safety Considerations

After the installation is complete, make sure to obtain a certificate of electrical safety from the electrician. Additionally, familiarise yourself with the unique characteristics of induction cooktops, such as their fast performance and excellent temperature control. These cooktops heat pots and pans with magnetic fields instead of flames or heating coils, so your cooking techniques may need some adjustments to suit this new cooking method.

Replace cookware

Induction cooktops work by creating a magnetic field between the pot and the magnetic coils beneath the cooking surface. The energy created in the electromagnetic field heats the contents of the pot. Therefore, it is essential to use ferromagnetic pots and pans for induction cooking.

Ferromagnetic cookware is made entirely of, or contains a layer of, magnetic materials that attract magnets. Cast iron, enameled cast iron, and many types of stainless steel cookware are all induction-compatible. Some non-stick pans also have a cast iron, enameled steel, or magnetic stainless steel base that can react with the cooktop to create heat. Aluminum, all-copper, or glass cookware will not work unless they have a layer on the bottom with magnetic properties.

To check if your cookware is compatible, simply hold a magnet to the bottom of the pan. If the magnet sticks, the pan is ferromagnetic and can be used for induction cooking. If the magnet grabs the pan softly, you may have some success with it on your cooktop. If there is no pull on the magnet, it doesn't contain the right metals and will not generate heat. Many manufacturers have started putting an "induction-compatible" symbol on the bottom of their cookware or noting compatibility on the packaging. The symbol often looks like a horizontal zig-zag or a coil.

If you have an induction cooktop and a favorite piece of cookware that doesn't work on it, you might still be able to use a product like a stainless steel induction hob heat diffuser. Place it on the cooktop under the pan; the heating reaction will then heat the contents of the pan.
