    Do you have any log book or registration details to say when it was installed? From looking at google it says from 1993, but I'm not 100% certain.

    the older the boiler " the better the boiler "

    cast iron, wall mounted, and floor standing boilers, last for

    decades, fifty years minimum............

    parts are available or should be kept in stock,

    and they are easy to repair.............bye.......

    I have a glow worm spacesaver 22-30 which is 30 years old at least. Gas engineer tried to get me to replace it with a condensing one, although it would have meant a lot of work due to location issues.

    He said it might last another few years, that was 5-6 years ago. Still no problems.

    Parts suppler for 50 CF MKll here

    The older boilers are less efficient, so the newer ones should be more economical to run.
    Bur i'm beginning to wonder if that's true, my combi is broken at the moment and they're saying it might need renewing even though it's only 8yrs old. Is it more economical to have a more efficient boiler if they last less than 10yrs.
    Now that i'm what you could describe as an older person i've stopped eating health foods.
    I need all the preservatives i can get.

And god knows how much that'll cost!

    Do you live in a hard water area? My boiler was making an awful noise before they serviced it. I think the heat exchanger just needed descaling. Have you tried using an additive in the heating water? Make sure it is the right type to actually get rid of scale then put in the type to prevent it building up. It still kettles a bit on start up of the flame, but relatively quiet after a minute.

    Glowworm ultimate 50cf ceased production in 2001, so it's at least 10 years old. Parts are still readily available though.

    Not much to go on one of these.

    What sort of noise is it giving?
  • just_looking
    It's making random bang noises, popping noises, and last Sunday night it sounded like an aeroplane taking off in the airing cupboard, I thought it was about to blow the doors off! I had to leg it downstairs and turn the power off

    Noisy boiler or heating pipes

    If your boiler or heating pipes are making hissing or banging noises, you should address the problem immediately. Ignore it and you might find yourself needing expensive repairs or even a new boiler.

    Don't imagine that fixing a noisy boiler is as simple as wielding a spanner yourself. The majority of boiler problems require the skills of a Gas Safe Register approved heating engineer. But there are a few checks that you can perform – which won't endanger lives and could help you give an engineer more information about the nature of the problem.

    Scale in the heating system

    The build up of scale can cause 'hot spots', which produce steam bubbles that make a loud bang. The problem can be treated with a chemical descaler, found at most DIY stores.

    This will involve:
    1. Shutting down the system
    2. Adding the product to the feed and expansion tank
    3. Leaving it to work for a few days
    4. Draining, flushing through and refilling the system
    Boiler thermostat is set too high or is faulty

    First, try lowering the boiler thermostat. Unfortunately, while this may stop the noise, it might also lower the radiator temperatures. If the boiler thermostat is faulty it will need to be replaced by a Gas Safe Register approved engineer.

    Insufficient water flow to the boiler

    There are a number of possible reasons why there isn't enough water getting through to your boiler, so you should check the following:
    • Water flow rate
      With modern, wall-hung, light-weight gas boilers, water flow rate is particularly important. Check that the mains water is on. If it is, check your feed and expansion tank (if you have them, they're usually found in the loft).
    • Float valve
      1. First, shut down your central heating boiler.
      2. Locate the tanks and double check that the float valve isn't stuck. If it is, you'll have to move its metal arm to release it.
      3. Check that the open safety-vent pipe is correctly installed. If not, air can get into the system, causing noise in the boiler. If this is the case, you'll need to enlist the help of a professional heating engineer.
    • Frozen water supply pipe
      If this doesn't work and it's currently very cold outside, then it's possible your water supply pipe may have frozen.
    Lack of water pressure in your boiler

    If the problem is a lack of water pressure, the pressure indicator on your central heating boiler will usually indicate that it needs to be increased

    Yes, we were told to turn thermostat down, but also the pump was on 1 so that's gone up to circulate more water, but chap said its just old, he's not the first to say its on It's last legs! I know there's sludge in it, when I moved in 6 years ago there was a blockage shortly after, and British gas tried the power flushing line, but so did my independent round the corner guy!

    This may be of interest,

    How old should your boiler be before you replace it?

    it provides a link to a database which lists the efficiency of boilers, even discontinued ones!

    it is easier to go to 'view boiler database' then 'gas boilers' then 'refine search' before entering your search term.

    kettling
    it sounds to me like your boiler is " kettling "

    or local boiling

    sludge and scale trapped in the heat exchanger bottom,
    is causing local boiling,

    the air is not free to boil in water,it is boiling in pockets of
    scale/sludge,

    clean your system, put fernox f3 in for a week,
    shut off all rads bar one

    drain and refill and drain with clean water,
    add fernox f1

    No, it's another green con. In the long term the modern "high efficiency" boiler costs more than a traditional boiler and uses more of the world's valuable resources.

    I will only replace my 37 year old Potterton when I am forced to. I'd buy another if I could.

    thank you
    I am of the same opinion that its a con. my very old (30+ years) boiler is still going strong and in the time I have lived here it has needed 2 valves at around £70 each (just to add been here 15 years)
    would tell you what make but cant remember and with nasty kidney infection back I wont leg it up the stairs to have a look..
    its in a cupboard upstairs and nicely dries four towels or pairs of jeans overnight, and saves me the bother of using the dryer for several hours in winter, so it may well use a little more gas than a new all singing and dancing condesing boiler but it saves me hours of electirc drying time
    and as a bonus it keeps the upstairs a bit warmer, cos I have no rads up there.


    cant help OP but can say the valve that broke did make a awful clattering noise when the heating kicked in, which is how I realised it was broken

    I have hung off for various reasons, but to be fair, I think many new technologies have teething troubles and the problems were due to inexperienced fitters and servicers as much as the boilers themselves.

    There are numerous reports that the German brands such as Bosch and Valiant are reliable. As might be expected they have been doing this for decades and would consider expelling almost a third of your energy up the exhaust then moaning about gas bills as ludricous.

    See this thread from 2006-2011

    http://forums.moneysavingexpert.com/showthread.php?t=310812

    This report from 2005 seems to confirm this as well

    Mr Cooper says his firm has avoided problems by limiting their list of recommended suppliers. His maintenance offshoot, which looks after 10,000 domestic boilers, limits itself to just one supplier - the German firm Worcester Bosch. He says he is considering including another German firm, Vaillant, on his list. "We are looking at it at the moment. I have to say the German brands are ahead of the British machines by a mile."
