What is an electric canner?
An electric canner, also known as a preserving pot, is a special pot for preserving food. You fill jars with prepared food, place them in the pot and cover them with water. Heating creates a vacuum in the jar, which keeps the contents fresh for a long time.
Modern appliances offer more convenience than simple pots. They have their own heating elements and digital controls. This saves time and delivers reliable results. You can find the best electric canners in our comparison.
Tip: Canning is perfect for fruit, vegetables, sauces and even complete meals such as stews. This gives you homemade supplies to enjoy all year round.
Buying an electric canner: what to look for
Choosing the right appliance depends on your plans. Ask yourself how often and how much you want to preserve. The amount of storage space available in your kitchen also matters.
Capacity and size
Capacity is given in litres. It determines how many jars you can process at the same time. A larger canner is more efficient, but needs more space.
- Small (up to 20 Liter): Ideal for single people or couples who occasionally preserve small quantities.
- Medium (21-25 Liter): A good all-round size for most households.
- Large (26 Liter and more): Perfect for families or ambitious home cooks with a large harvest.
Materials and build quality
The material affects durability and ease of cleaning.
- Stainless steel: Very robust, rust-resistant and easy to clean. The highest-quality choice.
- Enamel: A traditional material that provides good insulation. It can chip if knocked.
- Plastic parts: Look for high-quality plastic, especially for the lid handle and drain tap.
A tight-fitting lid with a rubber seal is essential. It prevents excessive steam from escaping and saves energy. An integrated thermometer helps you monitor the temperature.
Features and functions
The features determine how convenient the appliance is. A simple pot requires more attention.
- Timer: The most important feature on fully automatic models. The appliance switches itself off when the time has elapsed.
- Digital display: Shows the remaining time and current temperature.
- Jar rack: Protects the jars from direct contact with the hot base.
- Drain tap: Makes draining the hot water after canning much easier.
Important: Without a jar rack, the glass bases can crack due to direct heat. Always use a rack or place the jars on a heat-resistant trivet.

Descale the canner regularly if you have hard water. Use household remedies such as citric acid or vinegar essence. Then rinse several times with clean water.
Dry all parts completely before storing them. Leave the lid open or place it separately. This prevents musty odours.
Alternatives to electric canners
Canning is not the only way to preserve food. Depending on the food, other techniques may be suitable.
A food dehydrator is suitable for herbs, mushrooms or thin slices of fruit. It gently removes moisture from the food, while most of the vitamins are retained.
Freezing is the quickest method. You need enough space in your freezer for this. Not all foods are equally suitable for freezing.
Preserving food in oil, vinegar or alcohol is a traditional method of preserving. It is particularly suitable for vegetables such as antipasti or fruit.

Frequently asked questions
- What is the difference between a canning pot and an electric canner?
- A canning pot is a simple large pot with a rack. You have to regulate the temperature manually using the hob and time the process yourself. An electric canner has its own heating element, digital controls and a timer. It heats the water itself, keeps the temperature constant and switches off automatically when the time is up.
- What size or capacity do I need for an electric canner?
- The size you need depends on your household and how much canning you do. For small quantities and occasional canning, 15-20 litres is sufficient. For families that regularly preserve larger quantities of fruit and vegetables, 25-27 litres is ideal. This size accommodates several large jars at once, saving time and energy.
- What material should a good electric canner be made of?
- Stainless steel is the best material. It is robust, corrosion-resistant, easy to clean and guarantees a long service life. Enamel is a good alternative, but it can chip if handled improperly. Look for a securely fitting lid with a seal for good heat insulation and a practical tap for easily draining the water.
- Can I also freeze or dry food in an electric canner?
- No, an electric canner is designed exclusively for canning, also known as preserving. Food is preserved in jars using heat. To freeze-dry or dry food, you need special appliances such as food dehydrators or freeze dryers. The processes are fundamentally different.
- How do I clean and care for my electric canner properly?
- Allow the cooled canner to drain completely and clean it inside and out with warm water and mild washing-up liquid. Remove limescale deposits with a solution of water and vinegar essence. Dry the appliance thoroughly, especially the tap. Store it in a dry place and keep the lid separate so that the seal can breathe.
