This thread is full of useful snippets and there is clearly a lot of specialist knowledge about CH systems. I am grateful for what I have learned. But we could have got to this point a lot quicker if people had read my earlier posts with a bit of empathy and sussed out what I really needed to know. Just because a problem is posed in slightly alien terms doesn't mean that the questioner is dumb or ill informed. If the cost of getting information from this forum is that you mustn't upset the regulars by using strange or slightly academic terms then this wealth of knowledge is not accessible and the forum is wasted.
From the way the information is tightly metered out, you would question the motives of some of the 'experts' in posting at all. Ploughing through all the dismissive and offensive 'banter' is hard work and many people would have been put off long before the end of the six pages of posts on this thread.
I don't know why members react to a searching query as if it were a personal attack. If I have used terms that are too technical and unfamiliar then why should it be assumed to be BS? Fact is that the ones who shout loudest, know least.
Someone mentioned Wikipedia. Perhaps some of you should try that as a way into understanding how control systems work. Wiki is not 100% always but in basic topics like this, it is pretty reliable. It is ignorant to dismiss Wiki when you don't understand what it is saying. Every radiator you have ever installed is following the laws of Physics, remember.
It would be a shame if someone reading this thread came to the conclusion that the CH engineering community was a little isolated group who resist change on principle and can only respond to it with insults and nasty language. If the more moderate (and helpful) regular contributors were brave enough to point this out to the more childish ones, the forum could be a much more useful and friendly place. I can't imagine the childish ones would be reading to the end of a post as long as this one. They are more likely to have left and gone out in the street for a fight with the other kids out there.
