AGA running costs depend upon the model that you own, the fuel supply you use and how you use your cooker.
The AGA Signature, AGA Signature Induction, AGA Compact, AGA Mini and the award winning AGA ERA, are controllable and are designed to be left on like traditional models, with some options there are slumber settings, or you can turn them on and off as required.
AGA Cookers provide increased flexibility and greater control, providing the opportunity to lower running costs significantly thanks to fast heat up times and the ability to allow individual operation of ovens and hotplates. In addition, adjustable temperatures and the ability to turn off functions when not required enables you to control how much energy you use. For example, there is no need to leave hotplates on since they are designed to heat up in 10-12 minutes.
The AGA Classic is designed to always be on and ready to cook. Whilst this model may be more expensive to run, it also take the place of other electrical items such as heaters, an electric kettle and a tumble drier.
