    Should I replace my (possibly 20 y/o) Ideal Mexico 2 boiler with a modern combi?

    Should I replace my (possibly 20 y/o) Ideal Mexico 2 boiler with a modern combi? 13th Apr 19 at 2:17 PM
    The boiler is working fine but is an old conventional boiler, and what is quite annoying is that the central heating system has no 'y valve' so you can't have hot water without turning on the heating (in the summer we put the thermostat on minimum but it still comes on). I had some plumbing work done and the lads did a good job so I asked them to quote for a new combi boiler while they were there. The total cost to supply and fit a Worcester Greenstar 30i combi boiler would be 3576 - which I think is probably average for the London suburbs.

    The boiler existing conventional boiler has been here since I moved in 10 years ago, and was not brand new then, so it's maybe 12 to 20 years old. The model is an Ideal Mexico 2 B.E.D. which is a generic designation (unfortuantely all that I could find on the boiler itself and I spoke to Ideal too), but I have a manual which covers CF 40, CF 50 , and CF 60 which I assume are largely similar but have an increased capacity. As I have a 3 bedroom townhouse, I'm prepared to go with CF 50 as a likely candidate for a mid size house.

    I'm just wondering how long is the Ideal boiler likely to last before packing it in, and is it worth replacing it now? It appears to be working without a problem, and although it is annoying having to have central heating on to get hot water, with the thermostat turned down I have lived with it for 10 years. I know the efficiency savings from a combi boiler against a 15 - 20 year old conventional, will not remotely justify it; but with the piece of mind of a new install and separate hot water maybe it is worth it. Just would like to know what people think. Thanks

    Consider fitting a Y valve, you'll need one anyway if you update later.
    Loose means not tight, Lose means something is lost, simples no?
    Ignore me if you like, it's not the real me anyway.

    Is that correct? I read an article that the savings from the efficiencies of a modern boiler will no way pay for the upgrade unless you have it for decades. The current conventional boiler is maybe 15 years old, but I have read 40 year old boilers still working.



    Also, how complex and expensive is fitting a Y valve?

    It doesn't sound worth it to me, even a really inefficient boiler isn't going to justify that spend. Do you have it serviced annually?

    Not had it serviced for a few years TBH. If they are serviced yearly how long do Ideal Mexico 2 GF 50s last- I dont know if anyone has knowledge of boilers?

    How long is a piece of string but it'll last longer if it's regularly serviced than not.

    Best to get it serviced and take your lead from what the gas engineer says. If it's working fine then no real need to change it.

    I think our gas bill reduced by around 10% when we had an ancient boiler replaced. But you would also need to factor in the costs you now have for the CH being on when you don't need it and the water being always on when you need heating. My Mum has the same problem and her bills are a lot higher than mine, with a similar sized house.
    "Cheap", "Fast", "Right" -- pick two.

    If it's working, I wouldn't bother servicing it however do ensure you have a CO monitor. Our boiler is around 30 years old and hasn't ever been serviced. We're now at the point that it will be impossible to get replacement parts, so when our heating breaks down we'll have to get a new boiler... but we're not spending anything on it in the meantime. Our CO monitor went off once a couple of years ago - in the middle of summer with no gas on! - and the gas engineer who was sent out to confirm that there was no leak, commented on how much better the older boilers were and just to keep it until it stopped working.

    If the only reason for replacing it is to save on your gas bill then it's not worth it as by the time you have paid for it in savings it will be time to replace it, sounds like you have gravity hot water & should work without the heating being on, I'd get someone to see what the problem is with that, plus if you do decide to change a combi isn't automatically the right choice for your house
    I'm only here while I wait for Corrie to start.

    You get no BS from me & if I think you are wrong I WILL tell you.

    My boiler was fitted in 1981 and still works just fine so no plans to change it unless it dies!

    We also have to have the heating on to have hot water and we don't even have a house thermostat!

    No, I am not perfect, but yes I do judge people on their use of basic English language. If you didn't know the above, then learn it! (If English is your second language, then you are forgiven!)

    Is fitting an electric immersion heater in your HW tank an option?


    We've got the same boiler as you in our new to us house built in the 1960s. Don't know how old it is, probably the second boiler. The plumber who serviced it said they go on for years and years and are generally a lot more reliable than the new boilers. He was trying to discourage my OH from replacing it!

    Replaced my 27 year old Ideal boiler and cylinder with an Intergas Xtreme Xclusive 36 Combi with a 10year guarantee this month at a cost of 2600. Price included a Magnaclean system and Honeywell T6R smart thermostat. It took the engineer two days work. He did comment that the Ideal was a very reliable boiler and he was amazed at how clean the system was.



    My wife is happy to have instant hot water without having to think about heating the hot water cylinder.


    Got the quote through OVO energy.

    Back in 1981 my mother got a Baxi Bermuda fitted, about 10 years back I looked at getting it swapped out for a new boiler to save money. I worked out the payback time was about 20 years so decided to wait til it died and then it'd have to be done.

    Problem is the boiler is pretty bomb proof and now I own the house with no plans to replace it.

    We already have an immersion heater. I have not used it in years though as it was fantastically expensive to run it.


    Thanks for all the responses people

    My house had a back boiler that was fitted in 1967 and still worked, although it was noisy and starting to scale up. Since replacing 4 years ago with a combi the bills have reduced by about a third.

    If you've got an immersion heater, then I wouldn't replace your boiler until it becomes unrepairable as you will always have back up hot water. Just make sure that you have plenty of electric heaters in case it breaks down in winter.

    I would just get some quotes now so that you are ready to instruct an installer when necessary.

    I have a 22 year old Ideal Classic which everyone says is bomb proof so I am not going to replace it until it starts causing me problems (I haven't had any issues at all for the last 8 years). I have it serviced every 2 or 3 years.

    Also, I don't understand why the heating is coming on if the thermostat is set to zero. Are you sure that you don't have a fault?
