How environmentally friendly are AGA heat-storage cookers?

Each AGA heat-storage cooker is made in Shropshire, England from 70% reclaimed iron, including old cast-iron cookers, drain covers, old machinery, door fittings etc and, in turn each old AGA is 90% recyclable, meaning you'll never find one on a landfill site.

Most new AGA cookers are now programmable, meaning they work hard when you want them to and slumber when you don't. The AGA Intelligent Management System (AIMS) is a programmable device that powers down your AGA cooker when you are not using it, ensuring it uses energy responsibly. It comes as standard with the 13-amp electric models and is an optional extra with most gas fuelled AGA cookers

As an existing AGA owner why not find out more about retro fitting AIMS* to your AGA and reducing the amount of energy your AGA uses?

*Oil models need to be converted to electric to have AIMS fitted.

We're also dedicated to developing more efficient energy sources. This includes programs using micro-generated electricity such as wind, solar power and heat pumps.


What is AIMS and what does it do?

AIMS allows the AGA to reduce its temperature to a pre-set level between normal cooking events.

This can be either 'low' or 'slumber'

You can choose whether the AGA is operating on 'manual' i.e. at normal operating temperature or following AIMS Programs, or turned off and allowed to go cold.


Why do I need to leave the AGA on ‘normal’ for 48 hours before using AIMS for the first time?

Every AGA is individual with slightly different characteristics. When the AGA is commissioned the engineer sets the temperature control knob to the approximate position to achieve the correct oven temperatures. You will need to slightly adjust this control knob up or down to achieve the final correct temperature. These adjustments could take about 48hrs before you achieve the correct temperature. The cooker can then be changed over to AIMS.

AIMS has to learn how long it will take to reach the normal temperature that you have preset.

When AIMS is brought into operation for the first time, it might be late arriving for the normal event. On the second day it will compensate for this and may arrive slightly early. By the third day it will have learned the optimum time and remember it for the future.


When do I need to move the temperature control knob?

Only during the initial 48 hour learning period to ensure the temperature reaches into the black band on the handset, and then you do not need to move the control knob again. Subsequently changing the knob may require AIMS to relearn.


Does the AIMS program affect the whole cooker?

Yes, all cooking zones are affected, ovens and hotplates.


Can I use my AGA without my AIMS handset?

Yes, the AGA PCB will hold the latest programmed time, or you can simply switch to 'manual' mode to operate the AGA on normal temperature. If a replacement handset is needed, please Contact AGA Australia.


Is my AIMS cooker always in communication with the handset?

No, they only communicate every 15 minutes and only when in range. So, if the handset is brought out of a cupboard it may not communicate immediately and may need some catch up time. This can be actioned immediately by pressing the back button.


Is my AIMS unit real time and will it automatically change between GMT/BST?

No it isn't and you will have to reset the time in spring and autumn to the correct time. Likewise the handset will need to be re-programmed for a leap year.


Will the temperature on my AIMS cooker be able to fall to ‘low’ or ‘slumber’ between ‘normal’ events?

No, because the appliance is so well insulated the cooker retains its heat for long periods even when the gas or electric is switched off. We recommend a gap of at least 6 hours between normal events for the appliance to drop in temperature. For example, between morning and evening events it's unlikely that the AGA will fall as low as the 'slumber' temperature, and therefore its advisable to select the 'low' setting between these events.


Do I need to calculate the time for my AIMS cooker to switch on and warm up?

No, the AIMS unit does that for you; only enter the time that normal temperature is required.


What happens to my AIMS unit in a power cut?

Power cuts for less than 15 minutes should have no effect. Programs are safely stored in the AIMS unit inside the AGA and in the handset. Sometimes it will be necessary to press the 'I' button to handshake or even to carry out a full re-establishment. Remember that the cooker needs electricity to operate, therefore if the power has been off for long periods, then this will affect the warming up time and the AGA may not be ready for the next normal event.**


How do I carry out a full re-establishment on the 13 amp AIMS cooker?

Press and hold down the oven vent fan button located inside the AGA until the blue neon vent fan indicator flashes, and then release the button. Immediately after the neon starts to flash press and hold the + and - buttons together on the handset until the blue neon goes out completely. (The handset display will briefly say connect) then release the buttons. If the neon does not extinguish completely, but continues to flash with a faint output, then repeat the above procedure. When connection has been made, the screen will display the language options, use the + and - buttons to scroll through the options to the desired language, then press the 'I' button to confirm selection. If the language settings have to be changed the whole procedure will need to be repeated.


How do I carry out a full re-establishment on my Gas AIMS AGA?

Switch the control knob on the AIMS unit inside the AGA back and forth between manual and AIMS setting until the blue neon flashes. Immediately after the neon starts to flash press and hold the + and - buttons together on the handset until the blue neon goes out completely. (The handset display will briefly say Serial Number) then release the buttons. If the neon does not extinguish completely, but continues to flash with a faint output, then repeat the above procedure. When connection has been made, the screen will display the language options, use the + and - buttons to scroll through the options to the desired language, then press the 'I' button to confirm selection. If the language settings have to be changed the whole procedure will need to be repeated.


How long does it take for the AGA to go from low (200 Deg C) to normal (240 Deg C)?

The AIMS unit has an initial inbuilt memory by which it assumes that it will take 3 ½ hours to achieve normal temperature. Therefore, if you set the normal period to commence at 6.00pm the appliance will start to warm up at 2.30pm. On the very first occasion the appliance is used it will probably arrive late maybe by as much as 45 minutes. AIMS therefore remembers this, so the following day it will start earlier i.e. 3 ½ hrs plus 45 minutes plus 15 minutes just in case. If on this occasion the arrival is early or late, usually just a few minutes, further changes will be made to the memory for the next event. Consequently it could take up the 3 cycles to learn. AIMS then uses this formula for any other days where this same daily routine has been programmed. The AIMS unit will use the same process of calculating the warm up times if different programs are used on different days. So it could take a number of days before the appliance completely learns the entire program settings.


Can I cook during the AGA warm–up in AIMS mode or when the appliance is in low?

This will result in the 'normal' target temperature not being reached at the programmed time, the AIMS unit would then recalculate the warm-up start time thereby bringing the cooker up to temperature early on the next 'normal' event. It will take about 3 cycles before the program would adjust to the correct temperature. Therefore, constantly changing programs or moving the temperature settings or cooking outside the 'normal' events will adversely affect the AIMS memory, with the AIMS unit having to reset and compensate for these changes which will take a number of days.


I want to use the AGA in the morning and again in the evening. What is the best setting in between?

Use the 'low' setting; however, if the gap between the two events is less than 6 hours then it is best not to choose this setting. The AGA is so well insulated that it takes many hours for its stored heat to reduce; therefore it would probably never actually reach the 'low' setting and certainly not the 'slumber'.


What if I want a different program on a daily basis throughout the week?

No problem, but it will take longer to learn each of the routines, so be patient. Try and avoid regularly changing the programs. As each day will be different the AIMS unit has to initially learn each of the different programs, which could take a number of days.


How quickly will the AGA cool down?

Due to the efficiency of the insulation you may not feel any perceptible change in the warmth being given off for several hours


How do I know when the AGA is ready to use?

Providing you have told AIMS the correct time for the normal event, a glance at the heat indicator on the hand-set should show that the correct amount of stored heat is present. When you start to cook the indicator will show a drop in stored heat. This is normal and does not reflect the actual cooking temperature. However, it's advisable to have the cooker up to temperature 1 hour before you actually need to use appliance, this is to ensure the cooker has sufficient thermal store.


When should I use the OFF setting?

If you are not going to use the AGA cooker for several days or during a holiday period.


What do I do if I come home early and decide I want to use the AGA at ‘normal’ heat?

If the AGA is on 'low' mode that is between normal settings, you can do one of two things. Press the thermometer button on the handset to bring up the boost function. This will override the current AIMS program and bring the cooker up to normal temperature. To remove the 'boost' function simply press the thermometer button again. Alternatively you can turn the control on the base unit to 'Manual' - but remember to turn it back to the AIMS program afterwards.

Be aware that the AGA may take a number of hours to reach normal temperature depending upon the state of the program.


I have a large dinner party on the weekend and need to complete a lot of cooking, is it ok to use the AIMS program?

The AIMS program is intended to save energy when the appliance is not in use and the principle of cooking on an AGA is based on the thermal mass of stored heat. If you are cooking a large meal it's advisable to change over to 'manual' the day before this large cook commences to ensure that there is sufficient thermal mass and no drop off in cooking performance.


Why does my neighbour’s AGA warm up quicker than mine?

Every AGA is individual and therefore they can take slightly different times to heat up.


How do I know when the batteries are low on my AIMS handset?

The battery life is shown on the handset - 3 dark pips indicate a full battery. Battery life depends on usage.


What happens if the batteries fail?

If the batteries run out do not worry, the memory settings for the cooker are contained in the base unit, just put in new 4 x AAA batteries and the handset will soon show the correct settings.


My cooker had AIMS added after it was installed. Does this affect these guidance points?

No, but the original heat indicator might still be fitted to the front of the AGA and being giving conflicting temperature with the handset display.

Always go by the handset as this is the more accurate reading of stored heat.

My cooker was originally oil but has now been upgraded to electricity with AIMS.

The guidance still remains but you will notice some changes in the characteristics of the individual cooking zones.

Refer to the heat indicator on the handset rather than the indicator on the cooker (if still fitted).
