The new electric AGA eR3 150i offers everyday radiant heat for sumptuous cooking and that gentle AGA warmth when you need it. Designed in Britain, this cooker features cast-iron ovens for radiant heat cooking and is supported by a best-in-class conventional fan oven, which provides ease for quick cooking.



The hotplate operates using a powerful heating element and can be set to either the boiling or simmering setting. Around the outside of the actual hotplate is a further usable cooking area. This area can be used to simmer on when the hotplate is set to boil, and as a warming plate when the hotplate is in simmering setting. When set to boiling setting the hotplate reaches temperature in around 15 minutes from cold, while the simmering setting reaches temperature in around 12 minute

Hotplate settings:

  • Off
  • Simmer
  • Boil

Boiling function – The boiling plate is the hotter of the two settings. From cold, the boiling plate takes approximately 15 minutes to reach its operating temperature.

Simmering function– The simmering plate is the cooler of the two settings. From a cold start, the simmering plate will achieve its operating temperature in about 12 minutes.

To provide additional flexibility to suit your way of life, the AGA 3 Series 150cm includes a best-in-class conventional fan oven. Easy to use and with 90 litres capacity, this oven is ideal for quick and easy mid-week cooking. Complete with two baking trays, four grid shelves and a plate rack, this oven will suit all of your cooking needs.


This cooker has two cast iron ovens located on the left-hand side and controlled by rotary control, as well an additional option of a programmer/timer device for the top oven.  Using the control knob on the far left of the top plate, the top oven can be set to roasting, baking or the offsetting. The roasting and baking settings can be achieved from cold in around one hour. The lower simmering oven can also be up to full temperature in around one hour. The baking setting will provide a ‘warm to touch’ feel. 


The tall warming oven is located on the right of the cooker and is operated by a separate switch on the top-right. The warming oven features a large plate rack, which can hold 12 large dinner plates for warming prior to serving, and the shelf accommodates half-size AGA roasting tins and baking trays. The tall warming oven also provides space for keeping saucepans warm and could be used as a built-in storage space when not in use.


Roasting setting– Roasts and grills beautifully and is big enough to fit a 13kg (28lbs) turkey. Radiant heat means food keeps its natural succulence and flavour.

Baking setting– Heated to an ideal moderate baking temperature – ideal for cakes, biscuits and bread.

Simmering oven – Simmers perfectly by constantly maintaining the oven at just the right temperature for long, slow cooking. This develops flavours and will make even the toughest cut of meat melt-in-the-mouth tender.

All of our new generation of AGA cookers are designed to conserve energy, they have much more control and allow individual operation of ovens and hotplates. Patents cover these unique cast iron hotplates and ovens. These new AGA cookers consume less energy compared to other heat-storage radiant heat range cookers. The hotplates are designed to heat up within 10 to 12 minutes, we therefore reccommend that there is no need to leave the hotplates on 24/7, they will heat up very quickly when required everyday.  If you do leave a hotplate on with the lid down, the boiling plate can cost 7-8 pence per hour, the simmering plate 3-4 pence per hour (based on 14p per kWh)
