    Replacement radiator is colder at bottom than it is at top.

    I think that is my point. Our system is working and we can make do - but it is not working effectively and not giving us the comfort heat required for our house. Regardless of what anyone says, if I did spend money on getting it working better - it would still be old and prone to further...

    Replacement radiator is colder at bottom than it is at top.

    Fluff .... I so feel that I have been positively told off ... if not a good spanking. Yikes .... The reason I am following this thread is that your problems are not dissimilar to mine. I have a conventional boiler and 11 rads. Some of the rads do not heat fully particularly the one in the...

    Replacement radiator is colder at bottom than it is at top.

    Really? Not sure if you are being factitious or not!! I cant ever remember being knowingly ripped off and I have certainly never had the misfortune to come across any of the type featured in the TV programs etc. However, I do do as much research as possible if I am getting someone I don't...

    BG or local rgi for install?

    D_Hali - I did do as you suggested and used the link. However, I mentioned in another thread that the house is unusual in that it is double fronted, single backed, was part of one house now split in two etc. There is therefore an unusal layout etc. For that reason I done a room by room...

    BG or local rgi for install?

    Yes - the 937 would indeed do that. I dont know how much flow rate you can get through a shower head and also the rate of it discharge down the waste pipe. We sometimes get a slow discharge on our shower waste - presumably through temporary blockage. Incidentally, what is the best way of...

    Replacement radiator is colder at bottom than it is at top.

    Out of interest fluff - why do you think none of the local fixes can do it? My view is that - taking the 80/20 rule - probably 80% of all local professionals - be they engineers, plumbers, decorators etc - would do a decent job in that profession. The big fear for the customer is getting one...

    how does a fan work on a boiler

    I can see the standard will be raised quite considerably once you have qualified .... :D :D

    BG or local rgi for install?

    agile - have done the tests. I get 12l min out of kitchen tap on its own. The kitchen tap is a mixer and an old one so I'm not sure if is opening fully. Bath tap is giving me 20l min on its own i.e. 30 seconds to fill 10l bucket. When both on together the kitchen tap goes down to 7l min and...

    BG or local rgi for install?

    D_Halis - ah - had me worried for a second there. Nobody had mentioned about the cold water being gravity fed and most of the flow rate checks were done in bathroom (downstairs bathroom - to be fair though they all may have checked without mentioning it). Done as you suggested and sure enough...

    BG or local rgi for install?

    agile - the 15l per minute is the flow out of the bath taps. I have had four around and they all gave slightly different readings i.e. 15, 16, 18, 19 l per minute. I am taking the lowest figure. We live on a road in semi rural so not on an estate or other situation where the flow rate would...

    Replacement radiator is colder at bottom than it is at top.

    Fluff .... I have been following this thread - partly to learn and partly to understand better the problems with my own system. However, I'm losing the plot now so I can't imagine how it is for you. If you have a Homeserve contract I would be onto to them pronto and 'insisting' they either...

    BG or local rgi for install?

    Yes - have come to the conclusion that the 837 will pretty much meet the DHW at 15l minute. As there is just two of us we wont be in a situation where other waters taps etc are used during shower times etc. The only concern was the modulation frequency which is minimum at 12kw. Presumably...

    An inspector called

    I dont have a clue about the basic types of faults that occur. I think my point is that it is forgivable for any installer to make some basic errors. This installer has done everything to a high standard and is unlikely to forget to seal the flue after this. Hence he is now likely to be just...

    BG or local rgi for install?

    agile - we have two rad valves. The flow rate is about 15l per minute. Incidentally why do you suggest the 937. Thats a big beast and while it has got the hot water store - I'm not sure what the other advantages are.

    An inspector called

    I am about to have an install done and I would certainly settle for a 'generally done to a high standard'. I would be inclined to give the installer a call with a pat on the back and ask him to come around for a brew and touch it up at the same time. It would be unreasonable for any customer...

    BG or local rgi for install?

    mickyg - I doubt if anyone has ever been defeated by a BG quote - other than those pulling up on a horse. BG will fit a Vaillant837 and give two years homecare free. Currently I am paying £132 for homecare - full parts and labour and no call out costs etc - I'm not daft enough to pay the...

    BG or local rgi for install?

    petit - I'm sure BG wont do anything if they can get out of it. I have been a long time homecare cust, and for a time kitchen appliances, (tho dropped that a time ago). I also have had a few battles with BG - so far on each occasion I come out on the right side. Pendant - the general...

    BG or local rgi for install?

    Yes but this is my point. BG have given me a fixed quote for a working system. Whatever does not work afterwards becomes their problem. If they had prior recommended the piping or rads needed upgrading that would be a different matter of course.

    BG or local rgi for install?

    Well I got me some quotes for an install - no surprise BG is out there in front. Upshot is BG is about £700 to £800 more expensive that WB or Vaillant Approved installers for the same job. Install + powerflush + Magna filter + programmable room thermostat. The quotes are as like for like as...
