Fuel & Flue Options

Early AGA cookers were designed to burn solid fuel but since their initial production, the AGA has moved on to natural gas, LPG, Oil, 13amp and 30amp electric. Our renovated AGAs are always fitted with the latest specification, AGA (or AGA approved) burner or electrical element to ensure maximum fuel efficiency is achieved from our renovated AGAs.

All internal parts such as the burner and controls are brand new parts from AGA or new parts which are approved by AGA which is why we guarantee them with the same warranty as a brand new AGA; 1 year parts & labour and subsequent 4 years parts.

Flue Options

There are 4 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

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 flue-liner or with a fabricated using a twin-wall flue pipe, often made from stainless steel.

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.

Balanced Flue - Natural Gas & LPG Only

A balanced flue can be used when an AGA is being sited on an external wall using 2 pipes; one to bring in fresh air supply to the burner and one to discharge products of combustion.

Regulations apply to where a balanced flue can be situated. The flue cannot discharge within 600mm of any opening windows or doors or within that distance of an airbrick. There are also restrictions based on the presence of existing flue terminals, sanitary and drainage pipework, corners, eaves and facing surfaces.

Power Flue - Natural Gas & LPG Only

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.

Power flue pipe can travel up to 10 metres to an external wall, deducting 1 metre for every bend that the pipe takes.

Oven Vent – 13amp & 30amp Electric Only

With electric 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 into an existing conventional flue.


AGA cookers require a regular service at set intervals to maintain efficient running and overall good health of your AGA. 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
  • Every 5 years for 13amp Electric AGAs
  • Every 2 years for 30amp Electric AGAs

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

AGA Twyford has a network of engineers all over the UK and abroad who are able to provide AGA Servicing. Contact us for more information.
