Bang goes that theory. The thermal cutout is fully closed and is delivering enough juice to the PCB to light a 100W lamp (making sure it could cope with a load and wasn't just dirty contacts somewhere). What's left? A bloke in Plumb Center said one of his customers had a similar problem which...

Oilman, what you don't seem to appreciate is that sites like this are among the most beautiful things to emerge from the internet, if not the entire human race. It's partly why I read it with interest beyond the nuts and bolts. In today's ME! ME! ME! culture (for want of a better word) it is...

That's the next step. Trouble is, that wretched diagram doesn't tally with what's actually there. Will let you know how it pans out.

Thanks for that Chris. Yes, there is power to the unit as far as the thermal cutout and you needn't worry about my ability to test a circuit! The problem with their simple diagram on P9 is that it doesn't show enough to give any meaning to voltage checks. I was working on the assumption that...

Problem: Mira Sport 10.8Kw shower suddenly packed up. Symptoms: No lights (not even "standby"), no action. Nothing. 240V showing as far as thermal cutout above heater tank. Block circuit diagram http://www.mirashowers.com/onlinecatalog/pdf/p3279_2a.pdf doesn't show enough detail to work...

That was NOT sarcastic - it was genuine Yes 23 references, but most of them either irrelevant or cryptic or, to quote your good self... "Easiest way is to make the vent a combined feed and vent (ask if need more info)" QED Another promising one from Kev points to a broken link. Well I...

THEN DO A SEARCH ON THIS SITE THERE ARE 23 REFERENCES!!!!!! Chris, I may be stupid but please don't shout. Done that. Trying to find a definitive reference to combined vent and feed is far from easy. For instance, having spent ten minutes downloading and trawling through an Ideal...

Chris - The www isn't exactly awash with info on "combined feed and vent". Am I right in thinking that you can join the vent to the feed at a point below the tank, so expansion occurs upwards within the body of water? What's the point in having a vent at all, then? A lot to learn in this game!

Have her hermetically sealed. What are you two on about anyway - Heathrow?

DIY boiler servicing? Opening a whole worm of cans there, Oilman! Isambard, there's no contest on the digital/mechanical front if you want different heat settings at different times of day/night. Here's one...

You cannot escape the principle that more heat is lost from a hot body than a cold one - in other words, the hotter your house, the more heat will disappear outside. In the end, it's down to what you perceive as comfortable. Cold walls and hot air - fan heater scenario - do not necessarily...

Can't agree. Good information management is about making it easy for the reader. Although much good information lurks in dusty corners of the system, it's too often cluttered with disagreement, banter and stories about the cat. It would never make a book (that sells) in its existing form...

Chris, that's excellent. It clears up pretty well all the queries I had about previous definitions. The penny has dropped. You seem to be treating "the flue" as one system, which in many respects it is, whereas most of us ordinary mortals think of it as the bit that lets out the stink. It's...

Nah, I think I'll give up on the stickies. No-one takes any notice of me. You can understand why. Desilu's rooster? Trying to think... Des and Lucy... films... cartoons??

Repeating yourself a lot tonight, Oilman I said you were repeating yourself a lot tonight, Oilman

Have a heart, Chris. He can't hear what he's writing.

Maybe the answer is to keep one topic going to which suggestions are added. It wouldn't clutter the site and could enlighten those who can be bothered to read it. :wink: Agree, current discussions are messing up the sticky posts.

Guys Kevplumb has invited everyone to pitch in with adding to /polishing his sticky definitions. I've posted one about flues and wondered if you'd take a look. Longer term, is there a better mechanism for discussing sticky content? Or would doing so publicly be an education in itself? Paul

:oops: :oops: :oops: You have similar styles. They're all superb. :oops: :oops: :oops:

MV topic, penultimate par. "If you notice any moisture leaking from the valve body shaft, it probably will have got into the head and rusted it, and possibly the switche(s) as well. You need a whole new valve, and that means draining the system." PS Worth taking a leaf out of our own book...
