Hi I realise this thread is 9 years old, but my old boiler has been kettling for longer than that. It's an Ideal E-Type 35KW. I've had this system for 20 years and from the day I inherited it, it was wonky. The rads never got really hot. I messed about with it for about 10 years, becoming a bit...

OK Fair point, well made. I rather think we are confusing 2 issues here: some of you say I shouldn't even try unless I've done the 17th Ed by going to college and am fully certified; some are saying that maybe it can be done by an amateur if he does his homework. What say you? Yes, I...

Hello TTC, Thanks. I don't have the specialist devices you mention, but I will be acquiring them before I start, to measure r1+r2 and R1+R2 and all manner of stuff. I did find a set of tutorials I thought were rather good from Worcester College (UK) which also shows the minimum device...

I see the answer is not to mess with the electrics ( or the plumbing either: who would bother raking that up?) It's all very well telling me that home electrics is too complicated and that awful things will happen, but things arent that straightforward. I saw a You-tube video of a CU. It was...

I think some of you guys are really enjoying this: giving some upstart amateur a good kicking. I'd like to say you've hurt my feelings, but at my age I don't have any left I did find a wiki of all things which gave a really nice diagram overview of the system. Theres a bloody big switch...

OK, Thanks for the replies, anyway. (Doesn't anyone go to bed these days? ) Yes, I think I intend to go ahead, BUT I did ask for some common sense answers before. BTW, I read Dale Carnegie's book years ago and , if memory serves, found it gibberish. I don't recall him saying anything...

I have an old house which needs a decent electrical system and a modern consumer unit. I'm not a spark, but I have done lots of rewires over the years and I even have an old Which? book about electrical rewiring. Despite dire warnings from all directions, I intend to go ahead with this. Mains...

Thanks John, The window is part of an extension, but was added a long time ago, looks like. I don't imagine the work was done to any standard acceptable today by FENSA, or, in fact, anybody! I'm fairly sure theres no lintel, but I will do some exploratory work to check. Looks like just 2 rows...

Fair point, well made. However, you seem to know what you're talking about. Bearing in mind the circumstances I've laid out, do you think the procedure I've devised is reasonable? Regards Bruce

Thanks for the replies. This place is a little outside the envelope and so a lot of the concerns you all raise are not that important. It's unlikely that anyone will bother reporting me for this. And selling it isn't a concern, either. When I'm dead, the whole place is likely to be pulled down...

Well, not a great help. I'm not going to ask permission and I'm going to do it myself. So, what was the answer to the original question?

Hi, I have a window in an old house which is timber-framed and with no lintel. It's single glazed and the wood is bad anyway. I want to fit a smaller window and, as luck would have it, I've been donated a upvc window frame with 2 double-glazed windows. Nice. The new frame is about 2 inches...

Tony, If the resistance R is 5k ( measured by the meter) and the required impedance is 12K, then if Z(coil) and R are 90deg out of phase, the coil impedance needs to be 11K and the inductance at 50Hz is 40H. I havent measured it, but it sounds a lot. I forgot that mains relays must have an AC...

Thanks for the replies I probably need an RGI, but I'm dead reluctant to ask BG because their prices are OTT I see you have a search engine for local traders! I'll try that As for the solenoid resistance, unless I'm making a horrid algebraic error, if V=240 and I=20mA, then R = 12K doesnt...

HI, I have a 30 yr-old Ideal E Type RS (35N ) Balanced-flue boiler. The main burner is not lighting. There is power down to the gas-valve ( this goes to a solenoid, I believe, although it would be a 240V solenoid, whereas I have heard tell of 24V ones? ) The gas-valve 'knob' is grey. ( I...

Hi guys Thanks for the replies. I do take your point about the huge difference between DIY and trade agendas. Still, for DIY, this does seem an effective soultion. And, of course, it doesn't really cost anything: just elbow grease. You may be right about the sand. It isn't possible to tell...

Well, well, well. I wasn't expecting that. I get one reply and it's a silly one. Can you seriously believe that what I've done is more effort than ripping all those pipes out? Maybe we have different approaches: for you, maybe, replacing pipes in walls is easy; for me it was the other way...

Hi, I have an obsolete 8mm microbore CH system with pipework badly full of that hard black stuff. Several rads have never got hot for years. The house has a soild floor so that means that the pipework is buried in the walls and plumbers say the only solution is replacing the pipes , ha bloody...
