Thanks for the tips. I'll have a stab at it later in the week and let you know how I get on. First things first, I'll get hold of that emergency plumber number. Just in case :lol:

Ah, sounds like an old and much debated subject. Thanks for that. Had another thought, once you let go of the wire the body would be charged to 400kv. Possibly, there may be enough current to cause a rather nasty jolt once you landed on the ground. :idea:

Following on from my last post regarding the electrical conductivity of water, I have another electrical theory question for you (if I may) ... Very often in films etc. you see people getting electrocuted by appliances falling into the bath water. Would this happen in reality? Similarly, if...

Is this the type of switch you were referring to http://www.screwfix.com/app/sfd/cat/pro.jsp?id=12544&ts=46029 Also, are there any rules regarding the positioning of the flex plate. e.g. not directly beneath the radiator. Thanks.

Perhaps I should seek professional help afterall. :lol:

Thanks for the prompt responses! I was losing confidence reading 'seek profesional help' all over the place. Presumeably, its to stop fools from draining their system whilst switched on! :D

Having done a few Google searches, most DIY sites discourage the DIYer from touching combi system stating that professional help should be sought. I was planning to replace my bathroom radiator which would involve a partial draining of the system. My original understanding was that this...

I think it looks pretty good and feels better under foot. I'm also put off by the size of the step for a ceramic floor (after ply, adhesive + tile). I think Karndean looks plastic but the Amtico I've seen looks really effective.

The water was boiling?! Could have been electrolysing i.e. splitting the water into hydrogen and oxygen. Your biggest risk was probably being blown up! :lol:

Alternatively you could have a look at amtico flooring. The tile finish looks very effective. And don't be put off by comparisons to cheap laminate boarding. This stuffs high quality and has to be professionally fitted. http://www.amtico.com/home/whats_new.asp Mind you, its pretty...

Ah, fascinating stuff! Makes perfect sense now. I actually did a Chemistry degree some while back. Its all come back to me now ... electrolytes and free ions etc. Should have known better :roll: Perhaps thats why I'm an accountant now :lol: Thanks!

No offence taken. I understand the point your making. One more question though (Sorry but I do find this concept rather interesting as it seems to contradict my understanding of electricery (sic)). My understanding is that water is a pretty good conductor of electricity, a lot better than...

Pardon my ignorance, but where's the risk of shock if there's no electrical equipment? I read the IEC (I think) guidelines a while back and to be honest it went a little over my head. Am I right in saying that the risk is from the fact that there could be a PD between say a faulty appliance...

Thanks RF. Sounds sensible to me to have the timer in the transformer rather than the fan itself. No doubt I'll be needing a new transformer at some point in the future when mine burns out! I only bought this particular fan because I liked the facia :roll: (about £30 more than the...

I want to fit a dual electric/central heating towel radiator in my bathroom but have a couple of questions before I proceed... Where should I fit the fused switch? Inside the bathroom or outside? Do I need to earth bond all the exposed metal work in the bathroom if I go ahead with the...

I've wired it like this ... I'm pretty sure this is right but if you disagree let me know. Anyway, an update on the problem itself. I removed the transformer and left it freestanding on a block of polystyrene and am amazed! The result is total silence (I was at best hoping for a...

It hums all the time as the fan has a permanent live and a switched live. Is not particularly loud just constant and annoying. I think the ceiling may be amplifying the noise somewhat seeing as the transformer is connected to the joist. I like the idea of using rubber washers so will give...

I've just fitted a low voltage ventilation fan (Expelair LVDX200T) in my bathroom but am not happy at all with the constant humming noise the transformer is making. Has anyone else fitted this particular make and noticed the same? I fitted the transformer in the loft space, screwed into a...

All my chisels are blunt. Ahhh, I'll get the dremel to sharpen 'em up! :lol:

Well ... I bought the Dremel and am now wondering how the hell I've managed all these years without one! I've had it 2 days and used it on half a dozen different tasks all ready... Worked a treat on the plastic pipe. Done in 2 mins. Olive stuck on the compression fitting. No probs, just...
