Read this before Converting your Aga Cooker

We've seen a massive uptake in Electric Conversions over the past few years. To help you have realistic expectations of what to expect post-conversion, we've put together this guide.




If you've decided to convert your Aga Cooker to the Controllable ElectricKit System, you're probably wondering how your beloved cooker will perform or how it will work after the conversion is complete.


We've always listed the pros and cons of each model we sell, along with each conversion option. You can find these on each model/conversion page on the website. Hopefully, our honest approach to selling helps set expectations and give you an idea of whats being done, how it's done and how it'll work - which in turn increases customer satisfaction!


The main reason Aga Range Cooker owners are choosing to convert, is to avoid high running costs. Both of our controllable conversions offer reduced running costs, by allowing you to turn ovens and hotplates off/reduced their temperature when not in use.


They are not designed to kick out lots of ambient heat. The ElectricKit System has low running costs due to the insulation used and additional flexibility. The cast iron ovens are tightly wrapped in high-density bio-soluble ceramic fibre blanket. This has much better insulating properties than the standard vermiculite usually used in traditional Aga cookers. Preventing lots of escaped heat, means the heat will stay inside the ovens for longer, and reduce the amount of times the elements need to draw power from your supply.


Heat into the room, is heat you're paying for. In essence, using any Aga cooker to heat your house is VERY inefficient compared to modern central heating systems. The ambient warmth is a by-product of the cast iron ovens and hotplates but there is no such thing as free heat. If you're looking to convert your Aga cooker, but also want lots of ambient heat into the room - some compromise will be needed. You can turn the ovens to full temperature and hotplates on slumber, and have radiant heat into your room, but you'll notice the running costs will rise. Alternatively, if you want the cheapest running costs possible, reducing the radiant heat will help significantly.


The most efficient way of using your cooker, is to utilise the ovens as much as possible. We've found that keeping one oven on 24/7 if you're using them more than 2 or 3 times a day is most efficient. It saves you switching on and off and heating from cold each time. Turning the hotplates off when not in use is also efficient as you'll lose most of the heat once the lids are opened, therefore the element will kick in sooner. Turning the Aga Range Cooker off overnight and utilising an automatic timer will also prove to be beneficial when it comes to your energy bills! It's also worth checking with your supplier for your tariff prices and shop around if possible.


Pre-installation requirements are key. With every order of a controllable cooker/conversion, we send out our detailed pre-installation requirements which include electrical information for your electrician. You'll also get our own user guide with detailed information about each conversion. Please read these throughly and ask as many questions as you need. As mentioned before, we aim to leave you happy and content with your conversion, so honesty and realistic expectations are paramount!


Personally, I (Steven) absolutely love these conversions and I think they're injecting a well-overdue improvement to the industry. The controllability for summer months, ambient heat for winter, and the unparalleled heat up times makes them a perfect all-rounder.

Our black steel plinths are available to add onto your cooker order if required. They add additional height to the overall Aga dimensions and are available in multiple heights to suit your kitchen design. Traditionally, these British-made Aga Cookers were 851mm from the base to the top of the black enamelled surface. When do you need a plinth? If your worktop or ideal working height is taller than 851mm and you want your Aga Cooker to match them, you'll need a plinth underneath. Brand new Aga Cookers (as well as our ESSE and Everhot cookers) have a fixed height plinth built into the cooker body. If you need these raised higher, you'll need to lay marine-grade plywood or concrete at the required height before installation. What sizes of plinths are available? Our plinths are available in 50mm to 80mm sizes. They also allow for levelling of the base before the assembly of the cooker begins. How do I choose my plinth size? When choosing your required height, you should consider your finished floor height vs your worktop height. It's standard for Aga Cookers to finish slightly proud of the worktop, since the top plate is curved rather than a right-angle ( photo shown below ). If you were to finish level with the worktop, you will have a bigger 'valley' in-between, where crumbs and debris love to collect! Usually, the plinth is seated onto the subfloor, with finished flooring/tiles ran up to and around the plinth once the cooker is built. Alternatively, you can either seat the plinth directly onto the finished floor/tiles, as long as they can bare the weight of the cooker, or we can raise the plinth using the adjustment legs, to allow the finished floor to tuck underneath slightly ( photo shown below). If choosing this option, you should bare in mind the supporting feet in each corner of the plinth start at around 20mm from the front of the plinth. This means your flooring could run underneath for a depth of around 20mm if preferred. After the cooker is built, there are NO adjustments in height, without a strip down and rebuild. What do Aga Cooker plinths look like?

The internal cavities of Aga Cookers have historically been filled with loose-fill insulation. Inside the cooker body, there are lots of pockets and gaps around the cast iron conductions and burner casings etc. The insulation was poured inside after the build was complete, to rid the cooker of air pockets and insulate the cooker body. Diatomaceous Powder Insulation Early models of Aga cooker, like the Standard models made from the 1950's through to the Deluxe 1974 models (and some post-1974 models), would have originally contained Kieselguhr insulation power (or 'Diatomaceous Earth'). You can identify your model here. This is a fine, talc-like insulation, made from crushed up fossils called diatoms. It's satisfying to touch, but VERY messy to work with and instantly becomes thick clay once exposed to water or moisture. The good news is that amorphous diatomaceous earth is non-toxic. As with anything in powder or dust form - minimising exposure is key. You don't want to be breathing in lung-fulls of any dust or powder. If you're working with it, the proper PPE should be used; not just cloth or paper dust masks. Whilst the loose fill insulation may be ok, these models are still the most at risk for any asbestos exposure. AGA used asbestos rope seals inside their cookers for many years. These seals and gaskets are found inside the body of the older models explained above, and also around the lids and doors. Over the lifetime of these cookers, many of these gaskets and rope seals have been replaced for modern (safe) equivalents. AGA have previously reassured engineers and customers that undisturbed, these seals pose little risk and were of 'dust suppressed' or 'tightly woven' formats. Many of them have been exposed to moisture or grease over time which hardens them, meaning they're less friable in nature. They recommend that really old models of cooker are removed in one piece if possible and disposed of professionally.
