    ... he may have a degree, studied for a few more years to qualify as an ACMA and then topped up with some PQE and CPE! :p

    But on the other hand he might have been the bloke with the old bucket cleaning the swarf out of the lathe beds ... ;)

    If your boiler has just been installed and there is a problem of any sort then contact the installer immediately.

    With respect, to come online and ask well-meaning posters is not the best, or safest, thing to do.

    Good luck with it.

    Sorry initially my issue was with the new fangled boiler messages and next to useless instruction manual. We had the new boiler installed as it looked a tad complicated to do oneself. Also the computer messages and even the pressure gauge confused me. This morning had the upstairs floor up to look at the leak must have been caused/made worse as now a sealed system. Anyway it was an easy fix just released pressure and re-soldered the joint, topped up the system and it is now fine. I think the leak had been there for some years and the recent installation and chemical flush had made it worse.

    Anyway I installed the original central heating system with some help from a retired gas engineer years ago Unheard of now but the boiler was even secondhand when I plumbed it in years ago. So it has done well, dates from around 1980 or earlier - 1978 on the instructions! I don't know if I should admit this, not serviced for at least 17 years except for the pump I replaced myself about five or six years ago, so done very well. Looking at it inside it had started to burn the heat exchanger as the flames was slowly getting higher and also as a result developed a water leak - it would possibly lasted a couple more years as it was only dripping on an internal tray and evaporating. However with water and mains in close proximity and internal burner damage it made sense to replace it now. I blame it on that cold winter and having heating on all day:)

    Pleased to hear it is all fine now, you obviously understand what you are doing so my initial concerns were unfounded. Hopefully, the new boiler will use a bit less gas, so even though the old one might have lasted longer, you should gain a bit on efficiency over the coming years. My gas consumption dropped by about 10% with a new boiler installed two years ago.

    I am a bit worried that we might not actually save anything. You possibly already guessed that I am a bit of a skinflint. We do not really use the central heating that much. But this winter we had to give in as we ran out of wood for the fire. We normally only had the heating on if it turned really cold. Then only for one hour in the evening and heated water once a day with electric for half an hour. This new boiler has a mind of its own and as it is new we could end up using the heating thinking we are saving money - if you know what I mean. You won't believe this, but our main heating is an open fire fed with fuel gathered while walking my dogs! Wood from field hedges, trimming etc the odd old wooden log and anything else I can find that is combustable. We have a large open fire and it is really nice in the cold weather :)

    Well I hope for you that one day you'll be pleased you replaced it.

    I have no difficulty at all in believing you keep warm by collecting wood, as I did exactly the same for 10 years in an old, isolated farmhouse in Italy.

    We had no mains supplies at all, no water, gas, electricity or phone, in the days long before computers and mobiles, and very little money too, but we had a great lifestyle. We spent half our lives collecting wood for the winter but were lucky enough to have a chainsaw and live on the edge of an oak wood.

    However, it sounds like you are collecting small stuff - you must need one helluva lot of it to get through an English winter?

    Some of it is small others not. We had a rotten pear tree in the garden that we burnt this year. Also an old derelict shed. A few logs I came across on my long country walks, when I say logs I mean tree trunks and all the small bits! . I also found some coal (actually a few tons!) of very large stuff abandoned on the old disused railway line across Suffolk. Massive lumps that you can only get a few in the grate. The fun is actually lighting this stuff as some of it is very damp! Newspaper and twigs works well if you have the time to watch it - then the room fills with smoke until it gets hot enough to draw up the chimney!

    Also illegal not to be done by a qualified engineer with Gas Safe certification. If a domestic gas boiler blows up it reduces your whole house to dust, matchsticks, and a burnt meat smell.

    That was the reason I forgot to mention :)

    Anyway during that cold snowy windy weather we had a few weeks back snow blew into the boiler and somehow the pilot light was extinguished. Guess what it went boom and smell of burning and gas! That was last time we used the boiler. Turned it all off including gas (did use it carefully on one cold evening). It started leaking water from heat exchanger you know that large lump of rusty metal, possibly had for some time. Also fitter suggested that the flame had got larger and was eating into the heat exchanger. This was apparently a normal fault he had come across as he admitted that most people did not bother to have the boiler serviced once it was out of guarantee.

    Had a few quotes and the plumbers never condemned it just suggested it would be wise not to use it unless we really had to. That was just in the time scale between the quote and getting the Job done.

    The price varriation in quotes was horrendous. Between £2k-£4k including vat. Obviosly being a skinflint went for one of the lowest quotes at £2.2k.Heard some horrendous tales of woe of old people being charged up to £7k. Being a favorite conversation of mine down local pub now :)

    These newfangled A rated boilers must cost a fortune to run. Lit up like a Xmas tree with a mains powered wireless point. Every time somebody turns on a tap you get a few seconds of "pump over run" which I guess is just wasting gas heating water that nobody will use and then followed at random by Fan post-purge using more of your electricity to protect the cheap alloy parts from corrosive gas. I don't think this is going to last twenty odd years. Read some of the manual now and online chatter. I have a nasty feeling that after five years it has to have a major overhaul and am now told by a plumbing engineer as low as seven years is possibly the time it will fail. Time to move house :)

    That's the rub isn't it? You are forced (by law now I believe) to use certified installers due to overly sophisticated designs, which in turn have built-in obsolescence, which then forces you to have regular maintenance or "boiler cover" ... and so on.

    I hope however you are wrong on the gas consumption side. I made do with an ageing boiler (20 years +) until I reluctantly had to replace it two years ago.

    Despite my initial fears, the new one is much more efficient and consumes noticeably less gas. The radiators reach working temp much more quickly, so a one hour burst gets the house warmer than the old boiler did in double that time. It remains to be seen how long it lasts (?).

    We collected pine cones, stored them until dry and used them for lighting fires. They can spit violently so you must never leave them unattended, but they are nature's firelighters.

    Finding coal must have been nice - a bit like us finding a fallen oak, which did happen periodically. We soon learnt we needed to think ahead with fuel. Collect for the following year, otherwise your wood is too fresh or wet to give heat - it'll burn, but frustratingly badly. We also learnt which woods burnt the hottest or the slowest, which spat and which didn't, and how to keep a fire in overnight. In the 10 years we were there we became expert chainsaw handlers.

    The king of fuels for long, slow, all-day burning was olive, smelt good too, but was in short supply. Oak was our staple, which burns hot and lasts quite well. Pines and lighter woods flamed well, but gave little heat, spat and didn't last, but each had it uses in different circumstances.

    Nowadays I just press a button :(

    I don't know if you are like me. Being from an engineering/technical background I try to do everything myself. Car maintenance, plumbing, rewiring the house but no way will I do decorating except when nagged to :)

    When I think back to my very first house. It was a shell when I moved in. No plaster on the walls, roof was full of holes. Water on bathroom floor dripping off light fittings. It had no modern electrical wiring or any central heating. It had cord type wiring and bakelite type fittings. Did the lot myself albeit with some drunken help from friends. Having the floors up cutting holes and feeding pipes for heating was a great learning experience. Seem to recall at the time I had a book that described in great detail DIY boiler/central heating installation. We all sort of helped each other in modernizing our first time buyer homes. That would have been mid 1970's. To be honest we did not really have a clue then what we was doing then so nothing has changed :)

    My practical side comes from my father, who taught me to do most things I know. I think apart from enjoying it, he was driven by a lack of money to pay others to do something which he always felt he could manage himself. I don't have any particular training, but am able to maintain and repair most everyday things. For years, I too did my own motorbike and car repairs - even getting as far as changing an engine once - but cars were much easier to work on then, now I wouldn't dare try. Besides, I am older, with less energy and patience and prefer to pay others to do specialist tasks.

    I was in my element when in Italy, as we were in the middle of nowhere, with no-one around for miles to help in any emergency. We weren't self-sufficient by any means, we had jobs and bought stuff, and we had wheels too, but it was a hands-on existence for all our needs. I miss it. :(

    First if the pressure goes below 1 then most modern boilers will totally shutdown hopefully with a error you can look up.

    Second if it is a brand new boiler it is under warranty by law. Therefore you can ask the boiler supplier to sort any issues with a faults.

    I had a boiler that was install under one year, ignition system failed. Phoned up installation people they said no contact maker. Phone them they were round like a shot with a fully qualified technican fixing at their cost and signed off on boiler test etc.

    I was aware of this when my mother refused to go any other route other than British Gas - viewing them as the ultimate authority like the Vatican. Cost her £5500 five years ago.

    We had ours replaced before I left Worcester Bosch last year - bought the boiler and flue as a staff purchase and then had it installed by one of Worcester Bosch's Gold Standard installers. Cost £2700 all in, including the boiler, flue, installation, power flushing, thermostatic radiator valves and a new immersion heater, and five year guarantee.

    It's more complicated than that. The law in the case of boiler explosions is reversed - the manufacturer is automatically guilty under law and has to prove they are innocent.

    The standard of engineering and the complexity of the designs is concealed by the compactness of the boilers. The development timescale for a new product is just under two years and the degree of external certification required from a number of bodies is phenomenal.

    A bit like modern society in that we are all now guilty of some unknown crime. Don't get me started on that tangent :)
