Size

AGA

The AGA 60 is 60cm wide and 60cm (plus the handrail) deep.

Two and Three oven models - just less than 1000mm wide.

AGA 3 Series models - (approx.) 900mm, 1000mm, 1100mm, 1500mm, 1600mm and 1700mm wide.

Four and five oven models - just less than 1500mm wide.

An Integrated Module (for traditional models and AGA 7 Series only) adds a further 60cm to the left side of whichever AGA it's attached to.

2/3/4/5 oven models are about 70cm (plus the handrail) from front to back and you'll need a minimum of 140cm in height for the lids to open.

The AGA 60 and AGA 3 Series are closer to a standard worktop depth; they're around 634mm front to back, plus the handrail.

Ovens

AGA

AGAs have fixed-temperature ovens (you use whichever oven is at the temperature you need rather than altering the setting up or down). (The new AGA 7 Series eR7 models do now have a choice of temperature settings in the roasting and baking ovens.)

AGA 60: top oven can be set to either roast or bake setting, the bottom oven is a simmering oven. These are controlled independently of each other and the hotplate.

AGA eR3 Series: top left oven can be set to either roast or bake setting, the bottom left oven is a simmering oven.
For 100, 110, 160 and 170 models the bottom right oven is a plate-warmer and the upper right is unheated; it's just for storage. These are controlled independently of each other and the hotplate. The 90 and 150 models have one large warming oven to the right.

AGA R3 Series: top left oven (the only cast-iron one in this series) can be set to either roast or bake setting, the bottom left oven is a baking or simmering oven. The bottom right oven is a plate-warmer and the upper right is a powerful infra-red grill (on the R3 90-3 it's one tall warming oven to the right with a grill in the top. These are controlled independently of each other and the hotplate(s).

AGA R3 and eR3 Series: there is an optional section (about 60cm wide) with large fan oven below (and simmering plate on top) which fits to the end of the 90/100/110 models to form the 150/160 and 170cm models. It is colour-matched to the 'parent' cooker side and is only available with a brand-new cooker - it cannot be retrofitted.

Two oven: roasting and a simmering.

Three oven: roasting, simmering and baking ovens.

Four oven: roasting, simmering, baking and plate-warming ovens.

Five oven: roasting, simmering, baking, plate-warming and slow-cooking ovens.

All are (nominally) the same size and accept the same tins and trays.

Integrated Module: an upper (electric) oven with two functions - grill, or slow-cooking; lower oven - an electric fan oven.

Hotplates

AGA

AGAs have fixed-temperature hot-plates.

AGA 60 and AGA 3 Series have a large hotplate under the round insulating lid that can be set to either simmering or boiling temperature.

(The R3 100-4h 'Twin Hotplate' model has a large boiling plate and large simmering plate [no induction hob].)

The AGA 3 Series has an induction hob to the right (two-zone on 90, 100, 150 and 160 models, and three-zone on 110 and 170 models. (The 3 Series 150/160/170 models have an additional simmering plate above the fan oven to the left.)

Traditional AGAs, AGA 7 Series Models (AGA 7 Series models superseded the Dual and Total Control AGAs) all have a boiling plate (left-hand) and a simmering plate (right-hand).

The four and five oven AGAs also have a warming plate over the 'hotcupboard' side to the left (not for cooking, just for keeping things warm).

As an optional extra you can replace the warming plate on the hotcupboard with a two-zone gas or ceramic electric hob on a four oven AGA, or with a single-zone induction hob on the five oven AGA 7 Series (or Dual / Total Control) AGAs. (The gas hob and induction hob options are factory-fitted from new only and are not retrofittable.)

Heat Output

AGA

All models at full cooking temperatures emit around 1kW of heat to the room.

(That's about one 'bar' of an old fashioned three-bar electric heater.)

7 Series R7 (or Dual Control) with just the ovens on - about 0.85 kW to the room (0.625 kW economy / 'three-quarter' setting).

7 Series eR7 (or Total Control) set at 'Slumber' (hotplates off, just the ovens on at minimum setting) - about 0.32 kW to the room.

The AGA 60 and AGA 3 Series models emit about 0.50 kW to the room with both cast-iron ovens on at full heat, and even less still when some or all of the ovens are turned off.

Hotplates for AGA 60, 3 Series, Total Control and Dual Control

These are not meant to be left on.
In general, if you'll be using them again within an hour then just put the lid down but if you're not using them again soon, turn off and put the lid down.
The heat to the room from the boiling plate (or boiling mode on 3 Series / AGA 60) is about 0.50 kW and from the simmering plate (simmering mode for 3 Series / AGA 60) is about 0.22 kW .

Controls

AGA

Traditional AGAs have one heat-source for the whole cooker so have one control for the whole cooker. There are no separate controls for different ovens or hotplates and the cooker is designed to be on '24/7'.

7 Series R7 (or Dual Control) AGAs have constantly-on ovens but separate control for each hotplate.

7 Series eR7 (or Total Control) AGAs have separate controls for each hotplate and each oven.

The AGA 60 and AGA 3 Series have independent controls for their hotplate (and induction hob 3 Series models) and ovens.
The warming oven on AGA 3 Series models is also controlled independently of all other cooking zones.

(Nearly all AGA ovens and hotplates are 'fixed temperature' - when on they are at a constant setting. The adjustment with the thermostat is just that - a final small adjustment to your personal preference for the whole cooker. The only exception is the AGA 7 Series eR7 which has five temperature settings and its baking oven has four settings.)
Note - The 'hotcupboard' (additional two ovens and warming plate) for five oven AGAs is switched separately to the rest of the cooker. It's a simple on/off switch, not a temperature selector.

Integrated modules have 'conventional' ovens and hob so are controlled individually, and separately to the rest of the 'parent' AGA.

Programming / Energy Saving

AGA

7 Series eR7 (or Total Control)

Includes the 'Slumber' setting to greatly reduce heat-output and running costs.

The eR7 AGA's ovens (not the hot-plates) can be programmed to heat up in advance (from 'Slumber' or from being off completely) using its built-in seven-day timer. This works like a central heating timer - you set up the week to your preference, each day can be different if you like.

AGA 60 and AGA 3 Series

Available with an optional timer which can control the top oven (timer is NOT available for the 'R3' models). Note: this is the top oven only. This makes it easy to set the cooker to pre-heat the top oven for certain times of day on a '7 day' timer basis (much like you'd set your central heating timer). The timer is fed by a small cable from the cooker and needs to be mounted in a cupboard (or just above the worktop) next to the cooker.

7 Series R7 (or Dual Control)

7 Series R7s are not programmable.

Traditional AGAs

(Oil, gas, Economy 7 electric and 13amp electric) are designed to be on all the time. (The 'AIMS' programmable system for 13amp electric and some gas models has been discontinued.)

Heat-up Times

Traditional AGA

Designed to be up to temperature all the time so there is no pre-heating of the oven as there is with a conventional cooker.

Heating from cold takes around 10-24 hours for the cooker to reach temperature and the heat to 'soak' through and even out.

AGA 7 Series R7 (or Dual Control)

Ovens stay on (allow 8-12 hours from cold to heat thoroughly).
Hotplates (from cold) - simmering 8 minutes, boiling 12 minutes.

AGA 7 Series eR7 (or Total Control), AGA 60 and AGA eR3 Series

Ovens from slumber allow 1-1.5 hours to heat thoroughly.
Ovens from cold allow 1.5-2 hours to heat thoroughly.
Hotplates (from cold) - simmering 8-11 minutes, boiling 12-15 minutes.

AGA R3 Series

Ovens from cold allow 2-2.5 hours to heat thoroughly.
Ovens from bake to roast (top) or simmer to bake (bottom) allow 1 hour to heat thoroughly.
Hotplates (from cold) - simmering 20 minutes, boiling 40 minutes.

What's it made from?

AGA

Top, front, cooking ovens and hotplates are all cast-iron - excellent for heat retention and 'radiant heat' cooking.
(The hotcupboard on the four and five oven models have steel ovens, the lower oven on the R3 models are steel, as are the warming ovens on all the AGA eR3 and R3 cookers. The ovens in the Integrated Modules are steel too.)

Having cast-iron ovens means the oven floor can be used as a cooking surface - ideal for pizzas, and for baking quiches and tarts without having to blind-bake (or use the pizza/baking stone).

Fuel and Flue

AGA

Traditional models were available in electric gas and oil (discontinued in 2021).

AGA 7 Series R7 (or Dual Control) - always electric hotplates and electric ovens.

AGA 7 Series eR7 (or Total Control) - all-electric.

AGA 3 Series - all-electric.

AGA 60 - all-electric or electric ovens and four-zone gas burner hob.

All gas and oil models needed a flue - oil must be a vertical chimney (conventional flue) and gas either be this, or a smaller horizontal fanned 'power flue' (which has an audible fan mounted on the cooker).

Traditional electric models (13amp and Economy 7) had a small 28mm diameter pipe running horizontally to a fan box mounted outside to vent the cooking smells from the ovens.

AGA 7 Series models (and Dual and Total Control) are 'room vented' as standard, or have the option of a fanned oven vent system similar to that fitted to the traditional electric models.

The AGA 60 and AGA 3 Series are room vented and don't have any pipes or flue to outside (an extractor is recommended above them).

Servicing

AGA

Oil - every six-months.

Gas - every 12 months.

Traditional Electric - no regular servicing required, maintenance as and when needed.

AGA 7 Series and 3 Series - no regular servicing needed.
