    Hi all.

    Great forum,

    We had a WB Greenstar 37CDI Combi Gas boiler fitted in 2011, at the time it came with 5 year warranty from Worcester. We have had it serviced yearly and manual stamped and touch wood has been trouble free.

    The warranty is now expired and just wondering what you would recommend to do now ? I.e. Just service it yearly and fix on pay as you go if and when required or get some kind of homecare package on it for peace of mind ?

    Or just start putting money away each month for a new boiler on a rainy day

    Also we never got a magnetic filter fitted at the time as I was unaware Of such things, would it be wise to get one fitted now ? Which one ? I've read a power flush of the system would be recommended prior to getting one fitted?

    i would recommend putting something like £20-40 a month away or what ever you can afford and label it boiler repair / replace fund

    just to give you an idea normally the cdi series last 10 years before giving you problems (if installed correctly and serviced every year note burner seals need replacing every 4-5 years and heat exchanger cleaning )

    if you could i would have one installed and the system flushed and cleaned

    Many thanks for the info.

    Regarding the burner seals replacement, can you see these failing on a service which prompts the replacement or is it just routine that they need to be replaced after 5 years?

    Il ask our engineer to look into it on their next service in that case (not for a fair few months yet)

    Worcester Bosch offer their own service plans:

    Worcester Service Plan | Worcester, Bosch Group

    Whether one is for you depends on your circumstances and attitude to risk. For example, if you can afford the service plan but can't afford the occasional "WTF is wrong that can possibly cost that much; does it need an MRI scan and brain-surgery?" bill then you should probably lean towards getting one.

    If you do have enough cash in the bank to pay repair bills as they arise on average you'll probably do better in the long run having your installer service it annually and call in WB for one-off repairs on the relatively rare occasions it'll be necessary.

    If your boiler fails during a cold snap, you'll probably find WB give priority to their service plan customers. If you are young and fit can survive a few days without heating you'll find this prospect less worrying than if you have an elderly person or young children living in the house.

    My personal opinion, is that one should buy insurance only for risks like cars, buildings, personal injury where you can't cover the loss yourself. For everything else, self-insure and avoid 'toaster protection' plans like the plague. There's a reason people try so hard to sell them to you, and it isn't to benefit you. Over the years this has saved me a fortune.

    You can tell if the boiler needs a full strip and service by carrying out a fan resistance test as per the mi's once it passes a trigger value then you order a service kit, I would go on the worcester site and find your nearest Worcester accredited installer, they are trained to work on your boiler, don't buy insurance, find out how much a policy would cost, put that amount aside per month into a savings account, this is your boiler repair/ new boiler fund. As others have said adey magnaclean2, wouldn't bother with a powerflush at this point, see what the magnaclean looks like after 3 months, checking and cleaning every month, then annually.
