Fuels, Flues & Servicing

Early AGA cookers were designed to burn solid fuel but since their initial production, the AGA has moved on to natural gas, LPG (now available on DC models & modules only ), Oil, and electric. For some, the fuel option will be made simple by the fuels available to your property but with the introduction of a number of electric AGAs, with added flexibility, getting the AGA that is right for your situation may take some thought.

Running Costs

Information regarding AGA running costs is available on the relevant product page of each AGA cooker. Use the links below to go to the product pages for the cooker you are interested in, energy consumption is at the bottom of each page;

Flue Options

There are a number of flue options to consider with an AGA and in most cases there is one to best suit your property and to conform with Gas Safe, OFTEC and building regulations.

Conventional Flue – Oil, Natural Gas & LPG (LPG discontinued on these models 1/1/17)

The conventional flue (or open flue) uses a flue continuously rising from the top of the cooker and terminating above the roof. A conventional flue can be achieved by either lining a chimney with a flexible flue-liner or with a rigid twin-wall flue pipe on the external of the property.

A conventional flue for an AGA requires a 4” pipe out of the cooker, usually black vitreous enamelled, connecting into a 5” flexible flue liner or twin-wall stainless steel flue pipe. The flue must rise continuously with no horizontal or flat pipe. The flue cannot be in use by another appliance.

Power Flue - Natural Gas & LPG ( LPG discontinued 1/1/7 except on DC models )

A power flue is suitable for properties where there is no conventional flue option or where restrictions on balanced flues apply. It is ideal for cookers being sited on an internal wall or island unit. The 50mm power flue pipe can run up to 6 metres in length through a maximum of 6 x 90° bends or up to 9 metres with one bend.

Oven Vent –13amp AGAs Only

With electric 13 amp AGAs, there is no need for a flue however, just like all heat storage AGAs, the cast iron ovens are vented to the outside which on electric models is achieved through a 28mm (1") diameter copper pipe which can travel up to 6 metres to a small fan box mounted on an external wall or they can be vented naturally into an existing conventional flue (refurbished models only ). 

Room Vent – Dual Control, Total Control & City60 Only

AGAs new range of electric cast iron cookers can simply vent into the room like a standard electric range cooker. For Dual Control; Total Control and Aga 60 models these can be allowed to vent into the room if extraction venting by fan is not possible. Quite often, an extractor hood is fitted above the cooker to condensation as a result of cooking and any cooking smells.

AGA flues


AGA cookers require a regular service at set intervals to maintain efficient running and overall good health of the cooker. Servicing is recommended at different intervals depending on the fuel, as follows:

  • Every 6 months* for Oil Fired AGAs
  • Every 12 months for Gas Fired AGAs (Including the Gas Dual Control AGA)
  • Every 5 years for 13amp Electric AGAs, Dual Control Electric, Total Control & City60 (Interim service after 2 ½ years).
  • Every 12 months for Night-Storage (30amp) Electric AGAs (NOTE: This product is now discontinued)

* Servicing for oil fired AGAs may vary depending on oil quality.

Servicing should be carried out by a competent and suitable trained & qualified engineer.
