8 Costs to consider when installing an AGA cooker:
1. Which model to buy to get the cheapest running costs. If £80 a month to just run a cooker doesn't matter to you then you have got a choice of Oil, Gas, 13 Amp electricity. If £40 a month sounds better then you need a 30 Amp Electric AGA. An Oil AGA needs servicing twice a year, A gas AGA once a year, an electric AGA doesn't need servicing but AGA recommend having it checked once a year. The cost to have your gas AGA serviced is in the region of £120 (as of July last year – servicing by Spillers of Chard) or if you get a local independent then it will be cheaper.
2. Whether to buy new or second hand. You can get great savings on second hand ones that look like new. We bought our 30 Amp Electric AGA from Mr Cooker for £5500. Also see ebay and See Reconditioned AGAs. Also you need to decide on which size AGA you need – a 2, 3 or 4 oven AGA.
3. You need to install a flue for a GAS or Oil AGA. This means the AGA will need to be next to an external wall or have chimney into which the flue can vent into. A flue running up an outside wall can look ugly. You can get a version of the gas AGA that has a power flue. This means the AGA can be located in any position and it has a small pipe (about 25mm) that can then be carried along walls to the outside vent. The electric fan on this takes the exhaust fumes outside.
4. For the 30 Amp Electric AGA it has a small (15mm) vent pipe that goes to the outside – this can be run through your kitchen cabinets. A 30 Amp electric cable needs to run to the cooker from your meter board. You will need an off peak meter fitted to your property as the cooker works like a night storage heater heating up at night on off peak electricity. You can also make savings using this electricity to run your washing machine and dryer. You need to fit a timer.
5. For an Oil or LPG AGA you will need to site a fuel tank outside your house. You will need to build a base for it and install the pipework from the tank to the AGA location in the house. If you have an old cottage with very thick walls you will have to drill an hole through the wall.
6. If your AGA will be used to heat your water you will need a boiler fitted to it. This will need to be plumbed in. You may need another water tank installed for this, ask your plumber – the pipe work may be very expensive. The advantage of a water boiler is lashings of hot water. You can't fit a boiler to a 30 Amp Electric AGA, I'm not sure about the 13 Amp. The weekly running costs of the AGA will be higher with a boiler fitted.
7. For all the AGAs you need to install a plinth. You can either build this yourself or get a builder to lay it for you using a wooden frame and concrete it has to be exactly level and set for the day of installation. You will need to finish off the front of the plinth with tiles or paint. The alternative to making a plinth is to buy a metal plinth which looks very good in the matt black finish. This plinth can be adjusted on the day of installation.
8. If your house is listed you will need to get listed planning consent. There may be a saving on VAT if you are purchasing a new AGA.
As I'm not technical and these are from my experiences of installing my own AGAs you will need to get professional advice. See Installing an AGA and the main official AGA Cooker site for more technical details.Google+
