I would strongly suggest VIESSMANN, everyone in germany has one and they appear to be making some progress here in the UK. just my 2p worth

hi, i'm up in northern lincolnshire near grimsby. Our local BC come out and inspect boilers so myself and my friend are thinking of going down that route thanks Lorraine.

Hi all, does anyone know where i can buy an atag boiler from? my friend is after one and we've searched on the internet but nobody seems to sell them. Tried PTS and plumb center but no luck thanks lorraine

Hi Everyone. Have tried searching but can't seem to find an answer to my rather specific problem. Last year I had a new boiler (Viessmann) and unvented tank(Santon Premier) fitted along with all the pipework and radiators which I plumbed myself :D Only problem is now (within the last...

Hi Everyone I have been following this topic with some interest, I've been told on my plumbing course that you can do whatever you like in your own house, you only have to be registered to install into other people's houses. The only proviso, is you have to be a competent person. And I'd...

Hi When I went to the plumbers merchant to enquire, the guy in there said don't by anything unless its atag, keston, buderus, bosch or viessmann. avoid vokera like the plague is what he also said! So i would go for the bosch. I was under the impression that all new boilers had to be...

hi everyone I was going to take the troublesome radiator off the wall anyway and stick my pressure washer on the end of it, it seemed to work quite well on another sludgey radiator so I might give that a go before I hire a powerflusher! thanks Lorraine

hi everyone yes plumbing course is going okay. It is a lot easier than I expected. The maths and fluid mechanics, I find really easy but some of the actual plumbers find that hard!?! which is rather worrying. I've now gotten to the stage where I am confident doing plumbing and understand...

Hi everyone As I have a bit of time off I am in the process of sorting out my central heating. The problem is I appear to have sludge (black iron stuff) in my radiators as they are heating up at the top but not the bottom. So i went and got some fernox central heating restorer, drained the...

a lot of japanese stuff is rated for 100-230v because most of asia uses 230v. Hence if it is rated for this then brown is live and blue is neutral. no earth as its double insulated

err this sounds like you have bought t&E, but you need flex, which should have insulation on it!

i think you need the following: 1. certification your not stupid (you can self certify) 2. the ability to read and understand diagrams 3. the ability to use a screwdriver. thats my 2p worth Lorraine :D

Hi Everyone, I can't help but feel a bit sorry for nommienorman, I think he has been hard done by. To isolate the supply you must pull out the service fuse, its like a cartridge fuse for a fuseboard but a lot BIGGER!. You'll find it has seals on it (or you may find like me - it didn't)...

Hi Everyone Bahco - do you need a certificate to install an unvented cylinder? I thought anyone could do it. its just a matter of installing the relavent expansion vessel and pressure relieve valve I assume? Could he not get away with a 3 port mid position valve or must it be specifically...

Hi i'm no expert with unvented - in fact i'm not an expert at all! Is there any flow going through the outlet at all? if there is then the heat exchanger might be that efficient that all the boiler heat is being transfered to the hot water. if there is no flow or flow thats known as a...

units of Pascals = N/m^2 N/m^2 = kg/m^3 x m/s^2 x m Not sure if I speak for the majority or minority but a lot of tap fittings, especially european tap fittings (well the ones we bought) come with the bumpf in pascals. Lorraine

Hi Read this http://www.plumbingpages.com/featurepages/Heatloss.cfm The U value is actually based on thermal resistance Lorraine

Hi Everyone, I was looking on the internet and there is no mention of anyone fiddling with gas having to be mandatorily (is that a word?) CORGI registered, it just said, must be handled by a competent person? - whats the definition of competent?!? Is this governed by a qualification, if so...

hi chris, Apologies I forgot to put in the boundary layer resitance which according to the book is q = h x A x deltaT and you can work out the h (convective heat transfer coefficient) from the nusselt number which is Nusselt Number = h x L / k was discussing with hubby and he...

Hi everyone, Tony I take your point on board but I would expect that any decent plumber would actually check his work before hotfooting it in his van. I assumed checking for leaks was mandatory before he left? I only described him the way I did because gas is not like gardening, it is...
