4 Oven Aga Cooker

What It Is, Size & Who It Suits

What to Know Before Choosing a 4 Oven Aga

If you want the full “big Aga” experience, a 4 oven Aga is often the model people think of first. It gives you four separate ovens and the classic two hotplates, so you can roast, bake, simmer and keep food warm all at once.

On this page we explain what a 4 oven Aga is, which ovens and hotplates you get, how the hotcupboard section works, how much space you need, and the type of home it suits best. We will also point you to detailed guides on temperatures, dimensions, running costs and prices so you can decide with confidence whether a 4 oven Aga is the right choice for your kitchen.

At John Wray Range Cookers we specialise in reconditioned and converted Aga cookers, so everything below is based on real installations and how people actually live and cook with them, not just brochure diagrams.

What Is A 4 Oven Aga?

cof

A 4 oven Aga is a cast-iron heat-storage cooker with:

  • Four separate ovens
  • Two hotplates under the top lids
  • Often a warming plate on the top over the hotcupboard section (depending on model)
  • A heavy enamelled top that gives off steady background warmth

In a traditional layout, a 4 oven Aga is effectively a 2 oven Aga with an additional hotcupboard section on the side. The right-hand part of the cooker carries the main high-temperature ovens; the left-hand “hotcupboard” section provides extra low-temperature capacity and warming.

On most 4 oven models the ovens are arranged in two columns:

  • Right-hand side (main cooker section):
    • Top right – Roasting oven (your main high-heat oven)
    • Bottom right – Simmering or slow-cooking oven
  • Left-hand side (hotcupboard section):
    • Top left – Baking oven (moderate oven for cakes, bread and everyday baking)
    • Bottom left – Warming or plate-warming oven

The exact labels can vary slightly between generations and fuel types, but in most traditional 4 oven layouts the right-hand ovens handle the main cooking (roasting and simmering), and the left-hand hotcupboard provides the dedicated baking and warming ovens.

Compared with 2 oven and 3 oven Agas, a 4 oven Aga gives you significantly more capacity and more temperature zones ready at the same time, but it also needs more wall space and, on traditional always-on models, gives off more background heat.

Ovens and Hotplates You Get On a 4 Oven Aga

A 4 oven Aga is designed so that each oven has a clear role, and the extra hotcupboard side gives you more flexibility for entertaining, batch cooking and keeping plates and dishes ready to serve.

Roasting oven

The roasting oven is your main high-temperature oven. It is used for:

  • Roasts and joints of meat

  • Crispy roast potatoes and vegetables

  • Pies, pasties and savoury pastries

  • Lasagnes, gratins and similar dishes

  • Fast baked items such as pizzas and flatbreads

The top of the roasting oven is the fiercest area, with heat softening as you move lower. You can use this to your advantage – placing crackling and potatoes high up, and more delicate dishes lower down.

Baking oven

The baking oven sits at a moderate baking temperature and is ideal for:

  • Cakes and sponges

  • Biscuits and cookies

  • Traybakes and muffins

  • Bread, rolls and soda bread

  • Quiches, flans and general “everyday oven” cooking

Unlike a 2 oven Aga, you do not need to tame the roasting oven with a cold plain shelf to bake; the baking oven is set up for this kind of cooking from the start.

Simmering / slow-cooking oven

The simmering or slow-cooking oven runs at a much lower temperature and is used for:

  • Slow stews and casseroles

  • Pulled meats and braises

  • Long-simmered soups and stocks

  • Meringues and heavy cakes

  • Keeping dishes warm without drying them out

This oven allows you to cook ahead and let dishes finish gently while you concentrate on other parts of the meal.

Warming / plate-warming oven

The fourth oven is typically a warming or plate-warming oven. It is kept at a lower heat again and is perfect for:

  • Warming plates before serving

  • Holding vegetables, sauces and side dishes at serving temperature

  • Very gentle drying, depending on model and setup

For busy meals, this extra low oven can make a significant difference to how calmly you can serve several courses or a large table.

Boiling plate and simmering plate

On top of the cooker you still have the two classic hotplates under the lids:

  • The boiling plate, which is extremely hot and used for fast boiling, searing, stir-fries and getting pans up to temperature quickly

  • The simmering plate, which is gentler and used for sauces, porridge, eggs and general low-heat pan work

On some 4 oven models there is also a warming plate over the hotcupboard section. This is a useful place to rest cooked food and keep serving dishes warm before they go to the table.

You control the heat by moving pans between the hotplates, using lids up or down, and choosing which oven to use, rather than constantly adjusting gas burners. Once you are familiar with it, it is a straightforward and efficient way to cook.

Typical 4 Oven Aga Temperatures – Quick Guide

As with all Agas, exact temperatures vary by model, fuel and setup, but a traditional 4 oven Aga is designed so that each oven sits in a different temperature band:

  • Roasting oven – hottest

  • Baking oven – moderate baking heat

  • Simmering / slow-cooking oven – low, gentle heat

  • Warming oven – very low heat for plates and holding food

Broadly, on many 4 oven Agas:

  • The roasting oven behaves like a hot conventional oven, often in the low-to-mid 200s °C near the top.

  • The baking oven sits in a moderate range suitable for most cakes and everyday baking.

  • The simmering or slow-cooking oven runs in a lower “slow cooker” range.

  • The warming oven runs lower again and is used for plates and gentle holding rather than active cooking.

Because the Aga is a heat-storage cooker, there is usually no digital display on traditional models. Most owners learn their oven by shelf position and timing rather than aiming for an exact thermostat reading.

For a fuller explanation of typical Aga oven temperatures and how to translate conventional recipes, see our main Aga oven temperature guide.

4 oven Agas with modern electric conversions

When a 4 oven Aga is converted to a modern electric system, you keep the four-oven layout (roasting, baking, simmering/slow-cooking and warming) but gain more precise control over the heat and timings.

In day-to-day use this usually means:

  • You can set modes or target temperatures (for example Roast, Bake, Simmer, Slow Cook or a specific °C) for each oven.

  • Each oven continues to play its usual role, but you can choose when it is on, how hot it runs and, on some systems, schedule it to be ready when you need it.

  • The hotplates still provide boiling and simmering zones, but you can turn them up, down or off completely when you are not cooking.

To compare the electric systems we use and choose the right conversion for your 4 oven Aga, see our Aga electric conversion page. For typical budgets and price bands by system and oven count, visit our Aga electric conversion cost page.

4 Oven Aga Dimensions And The Space You Need

A 4 oven Aga is significantly wider than a 2 or 3 oven model. It is designed for kitchens with more wall space and generally suits larger rooms or chimney breasts.

As a guide, many traditional and modern 4 oven cast-iron Agas are around 1487 mm wide, about 851 mm high to the hob, and roughly around 680 mm deep, excluding the handrail and any rear clearance. For exact figures for each model, please see our Aga dimensions guide.

In most kitchens you need to check:

  • The clear width on the chosen wall or chimney breast – including any nibs, pipes or boxing that reduce usable space

  • That there is enough depth so the cooker does not project awkwardly beyond the cabinet fronts or into a walkway

  • That doors, drawers, walkways and islands still work comfortably once the cooker is in place

Clearances to walls, combustibles and any flue or flue-less requirements depend on the specific model and fuel or conversion system. All the detailed figures – widths, heights, depths, lid clearances and suggested recess sizes for every main Aga size – are set out on our  page.

If you are unsure, measure your space, compare it with the figures there, and then send us your measurements and a couple of photos so we can confirm whether a 4 oven Aga will fit comfortably and safely.

Fuel Types And Control Options For 4 Oven Agas

4 oven Agas have been built in a range of fuel types and control systems over the years. On the reconditioned market you will typically see:

  • Traditional oil-fired or gas-fired 4 oven Agas running as always-on heat-storage cookers

  • Night-storage or 13-amp electric 4 oven Agas, storing heat and providing four cast-iron ovens and two hotplates

  • Factory electric 4 oven Agas with modern controls and, on some models, extra hob options

  • Reconditioned 4 oven Agas converted to modern electric systems, with separate control over each oven and hotplate

Modern electric and conversion systems can offer:

  • Faster warm-up and cool-down from slumber or ECO modes

  • Independent control of ovens and hotplates

  • Programmable timers and, on some systems, app or remote control

  • The ability to reduce or switch off background heat in summer

  • Potential running-cost savings compared with older always-on oil or gas models if you do not need 24-hour heat

If you already own a tired or older 4 oven Aga, you may not need to replace it. In many cases we can strip it down, re-enamel the panels, renew worn parts and rebuild it so it looks and behaves like a new cooker. You can read more about what is involved on our Aga refurbishment page, and if you are weighing refurbishment against buying a different cooker, our Aga running costs guide explains typical costs and what is included.

If your main concern is ongoing bills rather than appearance, our  guide explains how different fuel types and modern electric conversion systems compare in day-to-day use.

How a 4 Oven Aga Compares to a 5 Oven Aga

When you are deciding between the larger Aga sizes, the main choice is often between a 4 oven and a 5 oven model.

A 4 oven Aga typically gives you:

  • A roasting oven (high heat)
  • A baking oven (moderate heat)
  • A simmering or slow-cooking oven (low heat)
  • A warming or plate-warming oven (very low heat)
  • Two hotplates (boiling and simmering)
  • On some models, a warming plate above the hotcupboard section

A 5 oven Aga usually adds an additional hotcupboard or extra low-temperature oven compartment on top of the four main ovens. This can provide more gentle heat for slow cooking, plate warming and drying, and tends to be chosen for very large kitchens or for people who regularly cook for bigger groups.

A 4 oven model is often the better fit if:

  • You want the extra capacity and convenience of four ovens but do not genuinely need a fifth
  • Your kitchen has space for a 1487 mm-wide cooker, but anything larger would feel dominant
  • You want to balance flexibility with running costs and background heat

If you are still deciding between all the Aga sizes, you can also look at our main Which Aga cooker should you choose guide for a full overview.

When a 4 Oven Aga Is the Best Choice

A 4 oven Aga is usually chosen by households that cook a lot and have the space to enjoy a larger cooker as a focal point in the kitchen.

It is often the best choice when:

  • You regularly cook for a larger family or entertain groups and want four ovens available at once
  • You like to serve everything hot and appreciate having a dedicated warming or plate-warming oven
  • Your kitchen has a long wall or generous chimney breast where a 1487 mm-wide cooker will sit comfortably
  • You want the traditional “big Aga” look and feel, with both roasting and baking ovens ready and additional low-heat capacity for slow cooking and holding food
  • You are comfortable with the extra background heat of a larger cooker, or you plan to use a modern electric or converted system to give you more control over when the heat is on

If several of these points sound familiar, there is a good chance a 4 oven Aga will give you the combination of capacity, flexibility and presence you are looking for.

FAQs

Is a 4 oven Aga too big for a normal family kitchen?

It depends on the room. A 4 oven Aga is wider than a 2 or 3 oven model, but many medium to large family kitchens can take the 1487 mm width comfortably if the layout is right. Checking the wall space, walkways and how it will sit with your units is more important than the number of people in the house.

What is the main difference between a 4 oven and 5 oven Aga?

Both have multiple ovens and two hotplates. A 5 oven Aga adds an extra hotcupboard or very low-temperature oven on top of the four main ovens. That extra oven is helpful in very large kitchens or for keen entertainers, but for many households a 4 oven cooker offers more than enough capacity.

How hot are the ovens on a 4 oven Aga?

On a traditional 4 oven Aga, the roasting oven runs hottest, the baking oven sits in a moderate baking range, the simmering or slow-cooking oven runs lower for long gentle cooking, and the warming oven is kept at a very low heat mainly for plates and holding food. Exact figures vary between models and fuel types, which is why most people cook by position and timing rather than a number on a dial.

Will a 4 oven Aga heat my kitchen?

A traditional always-on 4 oven Aga gives off noticeably more background heat than a smaller model and will usually act like a large heat source in the room. Many people enjoy this in autumn and winter. If you are worried about summer heat or want to keep tighter control, it is worth looking at modern electric and conversion systems that let you turn individual zones down or off.

Can my existing 4 oven Aga be converted to electric?

In many cases, yes. Systems such as ElectricKit and eControl can convert older oil, gas or solid fuel Agas to modern electric control while retaining the cast-iron body and appearance. A survey is always needed to check the condition of your cooker and your electrics, but for many owners this is a good way to keep the Aga they know while gaining more control and potentially improving running costs.
