Gas leak

Within a couple of days of getting the pilot lit we noticed that he AGA didn’t have the frequently described “gentle radiating heat” but rather a fierce intense heat and an odd smell. It turns out we had a gas leak. One of the obsolete parts, the Mag Valve or Safety valve of the Mk 1 Teddington, was toast, i.e. leaking. The technician who installed the oven walked me through the diagnosis (he is 4 hrs away) and sent me a used spare part to install.  A few hours of fiddling about with wrenches and pipe dope or thread sealant, and we were back up and running.  Now we have that gentle radiating heat and it runs much more quiet.

Things we learned:

  • If you smell what you think is gas, it probably is. Spray some soapy water on the pipes, if you see bubbles form that are the size of quarters, you found your leak.
  • A replace ment for the Mk1 Teddington cost about $1600 to $2500, installed by a technician.
  • agafixspares.com, located in the UK, sells the replacement burners for 595 GBP plus another 80-100 quid for shipping.
  • The replacement burners are on backorder.
  • agafixspares.com just received their first order of Oilwarm replacements for the Mk1 Teddington. These look very similar to the AGA version.  They are 575 GBP but most importantly, they are in stock (or more readily available).
  • If you are in the market for a used AGA make sure you know your burners. Study up and make sure you get a late model. Despite their appearances, not all AGAs are equal.

  1. I ran across your blog on the AGA.
    We’re considering purchasing an Aga for our new green home – but concerned Aga’s are not very green due to their fuel consumption.

    What have you found about the fuel consumption, and heat given off in the summer (wer’e in VA and concerned about the heat) compared to the cooking benefits?
    Thanks,

    • Hi Lisa
      “Green-ness” is very subjective. They use a lot of gas and to some people that is not very “green”. On the other hand, they displace other household appliances like electric kettles, microwaves and cut down on the use of furnaces and they can even displace water heaters.

      Consumption – We are on propane and it uses about 12-15 gallons a week. Propane prices follow gasoline prices so it it a little painful right now.

      Radiant heat – AGA’s do put off heat. In the winter, they can reduce the use of your furnance/ heating system. We found that our heat did not come on until it was in the 30’s outside. That is pretty good for a 2 story house.
      We have not been through a summer yet but i can already tell that radiant heat will be an issue. We are planning a summer shut down to reduce the amount of propane we use and the amount our AC runs. We grill out more in the summer anyway. If we need it for a dinner party we can always turn on for that occaision.

      My advice – buy an AGA because you love it not because they are green or not. If you are designing a kitchen, put in an auxillary range or outdoor kitchen to cover you for the shut down months. Auxillary ranges are fairly common in the UK. One design aspect, look into running a coil of copper pipe behind your AGA that feeds your water heater. this would act as a pre-heater and reduce the work your water heater must do. I have not looked into it but it makes sense to me. Also, consider looking for a used one. I am sure you could get a deal on one that someone is either scared of the energy prices or they moved into a home with one and they don’t like/”get” it.
      Good luck
