Types of Pressure Cookers: Electric, Stovetop and Multi-Cookers

Key takeaways

• Electric pressure cookers are easiest for beginners thanks to push-button controls and built-in programmes, while stovetop models offer more control and faster heat-up times.
• Multi-cookers with pressure settings are ideal in small kitchens, combining several appliances in one; a popular example is the Instant Pot Duo multi-cooker.
• Large pressure canners are designed for home preserving and are not always suitable for everyday one-pot meals due to their size and weight.
• Stainless steel pressure cookers are generally more durable and easier to maintain than aluminium, but they can cost more upfront.
• Capacity matters: compact 3–4 litre models suit one or two people, whereas 6–8 litre cookers better match family cooking and batch meals.

What is a pressure cooker and how does it work?

A pressure cooker is a sealed pot that traps steam, raising the internal pressure and temperature so food cooks faster than in a standard pan. By increasing the boiling point of water, tough cuts of meat become tender in a fraction of the usual time, dried pulses soften quickly and stews develop slow-cooked flavour without needing to simmer all day.

All types of pressure cooker share a few key parts: a sturdy lidded pot, a gasket or sealing ring, a locking mechanism and one or more valves to control pressure and release steam safely. The differences lie in how they are heated (on the hob or via an electric base), how pressure is controlled (manual vs electronic) and how many extra functions are built in.

If you would like a fuller overview of how size, pressure levels and safety systems interact, the dedicated pressure cooker buying guide on types, sizes and safety is a useful next step once you have finished this article.

The main types of pressure cooker

Most modern options fall into four broad categories: electric pressure cookers, traditional stovetop models, all-in-one multi-cookers that include pressure programmes, and large pressure canners designed primarily for preserving. Each can be found in a range of sizes and materials, and some blur the boundaries slightly, but thinking in these four buckets makes the choice much clearer.

Electric pressure cookers

Electric pressure cookers are countertop appliances with a built-in heating element and electronic controls. Instead of sitting on the hob, they plug into a socket and are programmed with buttons or a digital screen. Many people know them through popular branded multi-cookers, although there are also more straightforward electric-only pressure models.

How they work and what they are like to use

An electric pressure cooker has a removable inner pot (usually stainless steel or non-stick coated), which sits inside a housing that contains the heating element and sensors. You add your ingredients, select a cooking programme or time and pressure level, and the machine does the rest. It will bring itself up to pressure, maintain that pressure and then either keep food warm or switch off once the time is reached.

Because the electronics constantly monitor temperature and pressure, they are forgiving if you are still learning. Many models offer pre-set modes for things like rice, stews or pulses, so you can get good results with minimal guesswork. This makes them especially attractive for beginners or anyone who prefers a hands-off, “set and forget” style of cooking.

Typical capacity, features and safety

Electric pressure cookers most commonly come in capacities of about 3, 5, 6 and 8 litres. For one or two people, a 3–4 litre size is compact and easier to store, whereas a 5–6 litre model is often considered the sweet spot for families. Larger 8 litre versions, such as some bigger multi-cookers, suit batch cooking or those who like to cook in bulk for freezing.

Safety systems tend to be extensive: multiple pressure sensors, locking lids that will not open under pressure, automatic temperature cut-offs and controlled steam release. These layers make electric models generally very safe when used according to the instructions. The trade-off is that they can be bulkier and slower to reach full pressure than a powerful hob-heated pot.

Best use cases for electric pressure cookers

Electric pressure cookers are ideal if you want convenience and consistency. They are particularly good for:

• Busy households who appreciate being able to walk away while dinner cooks.
• Users who are slightly nervous about older-style pressure cookers and prefer clear digital displays and alerts.
• Kitchens where hob space is limited, as the cooker can live on a worktop.

If you are specifically looking for beginner-friendly options, there is a dedicated roundup of the best electric pressure cookers for beginners that explores this type in much more depth.

Stovetop pressure cookers

Stovetop pressure cookers are the traditional style that sit directly on a gas, ceramic, induction or electric hob. They look like deep saucepans with locking lids and one or more valves on top. They do not have electronic controls; instead, you manage the heat from the hob to control pressure.

How they work and what they are like to use

To use a stovetop pressure cooker, you place it on the hob, bring the contents to a boil with the lid locked, then reduce the heat once it reaches pressure (often signalled by a rising indicator or the sound of steam escaping from the valve). Maintaining a gentle, steady release of steam usually means you are at the right pressure.

This hands-on approach gives experienced cooks a strong sense of control, but it does mean paying closer attention while the cooker is in use. Once you get used to the signs and sounds of your particular model, the process becomes quite intuitive.

Typical capacity, materials and safety features

Stovetop models often come in 4, 5, 6 and 8 litre sizes, with some specialist options above that. They are usually made from stainless steel or aluminium, sometimes with layered bases to improve heat distribution on induction and electric hobs. A common family-friendly example is a 6 litre stainless steel pot with a 22 cm diameter, similar in size to the Tower 6L stainless steel pressure cooker with steamer basket.

Modern stovetop cookers are fitted with multiple safety mechanisms: locking lids, primary and secondary pressure release valves, and gaskets designed to vent safely if necessary. When used correctly and kept in good condition, they are safe; however, they rely on the user to control the hob heat manually, so they suit those comfortable paying attention during cooking.

Best use cases for stovetop pressure cookers

Stovetop pressure cookers often reach pressure faster than electric ones because they can take advantage of the full power of your hob. They are well suited to:

• Home cooks who like more control and do not mind being hands-on while cooking.
• Households with powerful gas or induction hobs where rapid heat-up is a priority.
• Those with limited worktop space who prefer to store the pot in a cupboard when not in use.

Smaller models, such as a 4 litre stainless steel pan similar to the 4L stainless steel pressure cooker from a basics range, can be a good entry point for singles or couples who want to experiment with pressure cooking without a bulky appliance.

If you are torn between an electric model and a traditional hob-based pot, it is worth reading a direct comparison such as electric vs stovetop pressure cookers: which to choose to see which style fits your cooking habits.

Multi-cookers with pressure settings

Multi-cookers are electric countertop appliances that combine pressure cooking with several other functions, such as slow cooking, steaming, sautéing, yoghurt making and more. They are essentially electric pressure cookers that have been expanded into all-in-one machines.

How they work and typical features

Like standard electric pressure cookers, multi-cookers have a removable inner pot, heating element and digital control panel. The key difference is the range of modes: you might find settings for pressure cooking, slow cooking, rice, porridge, sautéing, steaming and warming, among others. Each mode adjusts temperature and timing automatically, so you are not constantly fiddling with manual settings.

A well-known example is the Instant Pot Duo 8L electric multi-cooker, which offers multiple cooking programmes and a generous capacity for larger households or batch cooking. While you do not need to choose this specific model, it illustrates how a single appliance can replace several separate gadgets.

Benefits in a small kitchen

Multi-cookers are especially helpful in compact UK kitchens where cupboard and worktop space are limited. Instead of owning a separate slow cooker, rice cooker and pressure cooker, you can often manage with one machine that does them all reasonably well. For many people, the pressure cooking function ends up being one of several tools they use regularly.

However, there are trade-offs. Multi-cookers can be taller and heavier than single-function cookers, and the sheer number of buttons can feel overwhelming at first. If you rely heavily on one style of cooking (for example, slow cooking), it is worth checking that the performance in that specific mode is as good as a dedicated appliance. The article Multi-cookers with pressure settings: are they worth it? goes into more detail on whether the extra versatility justifies the footprint and learning curve.

Best use cases for multi-cookers

Multi-cookers are well suited to:

• Small flats and student kitchens where one appliance must do it all.
• Families who enjoy meal prepping and batch cooking a range of dishes.
• Cooks who like experimenting and appreciate having lots of modes within a single device.

They also make it easier to follow recipes written specifically for this style of appliance, as you can often match the programme names directly on the control panel.

Pressure canners for preserving

Pressure canners are large-capacity pressure vessels designed primarily for home preserving, particularly low-acid foods such as vegetables, stocks and some meat-based recipes. While they look similar to oversized stovetop pressure cookers, their purpose is different, and they are usually not the best everyday option for weeknight dinners.

Typical features and sizes

Pressure canners are usually much larger than standard cookers, commonly around 16–23 litres or more. They are designed to hold several jars at once on canning racks, ensuring even heat and pressure during the preservation process. Most are made from aluminium to keep weight manageable despite the size, though this does vary by brand.

The control system may be a weighted gauge, dial gauge or a combination, allowing you to reach and monitor precise pressures needed for safe preserving. Because accuracy is crucial for food safety in canning, many users consult reference charts and guidelines to set the correct pressure and processing time for each type of food.

Best use cases and limitations

Pressure canners shine if you grow your own produce, buy food in bulk or enjoy stocking up the pantry with shelf-stable jars. They allow you to safely preserve foods that cannot be processed with a standard water bath canner alone.

However, their sheer size and weight make them less convenient for everyday one-pot meals. Heating a massive canner just to cook a small stew is slow and energy-inefficient, and storing such a large pot can be challenging in smaller homes. A separate guide on pressure canners vs standard pressure cookers for preserving can help you decide whether you truly need a canner or whether a regular pressure cooker will cover your needs.

Materials: stainless steel vs aluminium

Beyond type and size, one of the biggest choices you will face is material. Most pressure cookers and canners are made from either stainless steel, aluminium or a combination (for example, stainless bodies with aluminium bases for better heat distribution).

Stainless steel pressure cookers

Stainless steel is durable, resistant to staining and generally easier to keep looking good over time. It is a popular choice for both electric and stovetop pressure cookers, particularly in mid-range and premium models. Stainless steel pots, like many 6 litre family-sized cookers or compact 4 litre designs, can feel reassuringly solid and are often suitable for induction hobs when the base is appropriately constructed.

On the downside, stainless steel is typically heavier and more expensive than aluminium. It can also develop hotspots on certain hobs if the base is not layered properly. However, for many households the balance of longevity, appearance and performance makes stainless steel a strong option. If you want a deeper dive here, the guide on stainless steel vs aluminium pressure cookers explains these trade-offs in more detail.

Aluminium pressure cookers

Aluminium cookers are usually lighter and more affordable. They heat up quickly and respond rapidly to changes in hob temperature, which can be an advantage for stovetop models. Many large pressure canners use aluminium specifically to keep weight manageable.

However, aluminium is softer than stainless steel and more prone to marks and discolouration over time, especially on the outside. It is also often not compatible with induction hobs unless it has a special base. For many everyday home cooks, a well-made stainless steel pot strikes the best long-term balance, but aluminium still has a place where size and weight are a priority, such as canners or large stovetop cookers.

Sizes and capacities: compact vs family size

Picking the right capacity is just as important as choosing the type. Too small and you will struggle to cook enough food in one go; too large and you end up wasting energy and valuable storage space. It is also worth remembering that you can never fill a pressure cooker completely: most manuals recommend staying below two-thirds full, or even lower for foods that foam or expand.

Compact pressure cookers (around 3–4 litres)

Compact 3–4 litre cookers are ideal for individuals, couples or very small kitchens. They take up less cupboard room and are lighter to move around. A 4 litre stovetop pot, similar to the compact 4L stainless steel cooker mentioned earlier, is well suited to making small batches of curry, soup or a stew for two with leftovers.

The compromise is flexibility: if you suddenly need to cook a large batch of chilli for guests or prepare stock from a big chicken carcass, you may find the smaller pot limiting. For many people, though, especially in flats or student accommodation, the trade-off is worth it.

Family-sized pressure cookers (around 5–8 litres)

Family-sized cookers in the 5–8 litre range are the most popular for households of three or more and for batch cooking. A 6 litre stovetop pot like the Tower 6L model with steamer basket strikes a good balance between capacity and usability on the hob. An 8 litre multi-cooker, similar in size to the Instant Pot Duo 8L, is great for large families, batch cooking and those who like to freeze portions.

To think through capacity more systematically, you can use the dedicated guide on family size pressure cookers and how big you should go, which walks through typical household sizes and cooking habits.

Which type of pressure cooker suits you?

Once you understand the types, the next step is matching them to your kitchen, your cooking style and your confidence level. You might find that more than one type appeals, but usually one will fit better once you think about how you actually cook on a typical weekday.

For beginners and nervous users

If you have never used a pressure cooker before or feel anxious about the idea of pressurised steam, an electric pressure cooker or multi-cooker is usually the gentlest introduction. The clear buttons, automatic pressure control and multiple safety features remove much of the guesswork. You can follow recipes written specifically for your model and gain confidence gradually.

Many people who start with an easy-to-use electric model later decide whether they want to upgrade or add a stovetop pot for specific tasks. The guide to the best electric pressure cookers for beginners can help you narrow down options if you decide this is the right path.

For small UK kitchens and limited space

In a small kitchen where worktop and cupboard space are both tight, multi-cookers with pressure settings often make the most sense. They can replace several bulky gadgets, letting one appliance handle pressure cooking, slow cooking, rice and more. The main considerations are height (will it fit under wall cabinets?) and where you will store it when not in use.

Alternatively, if you do not need lots of modes, a compact 3–4 litre stovetop cooker can tuck neatly into a cupboard and come out when needed, taking up no permanent worktop space at all.

For speed and control

If you are confident in the kitchen and value speed above all else, a good-quality stovetop pressure cooker is hard to beat. It can reach pressure quickly, is straightforward to use once you understand the signals, and does not rely on electronics that might eventually fail.

Pairing a decent stovetop cooker with clear safety habits, such as those in the guide on how to use a pressure cooker safely at home, gives you a very capable tool for everything from stocks to stews.

For home preservers and batch stock makers

If your main goal is preserving jars of home-grown produce or making very large batches of stock and soups, then looking at pressure canners specifically may be worthwhile. They are specialist tools, but for serious preserving they provide the capacity and control you need.

For most everyday home cooks, however, a regular 6–8 litre pressure cooker or multi-cooker will be more practical, easier to store and more versatile for regular weeknight meals.

Whichever type you choose, remember that accessories like steamer baskets, trivets and spare gaskets can make day-to-day use smoother. The overview of pressure cooker accessories and features that really matter is helpful once you have narrowed down your main cooker type.
