Pub Argument - Boiler Connections

[jono_h]

Does anyone care to settle a pub argument between friends?

The difference of opinion concerns boiler connections - one side thinks that the flow connection on the boiler is the flow to the system (pump / 3 way valve), the other thinks that it is the flow from the system (from last rad / Hot Water Cylinder)

Who's right, or is it boiler specific? (As you can tell none of us are plumbers - just engineers with too much time on our hands, and a tendancy to talk technical when we're drunk)

Ta,

Hi,

The flow pipe always leaves the boiler & the return (returns) to the boiler

c'mon you pesky engineers........

Who on earth is that? Someone from Big Broterh or some other program I dont watch.

Water flows OUT of the flow and returns back into the boiler at the return. But I would have thought that was obvious even to my Polish plumber!

Thanks for the replies. I too thought it was pretty obvious - the boiler is the primary component, and so the flow pipe is the flow from the boiler.

That earns me a couple of easy pints - if you're ever near me feel free to claim a half!

Of course in a modern boiler the internal pump is on the return, but when we fit a modern boiler that doesn't have a pump we put it on the flow. Many older systems have pump on the return. So position of pump says nout, you have to look properly at a system to decide how it was piped, and sometimes can't figure it all out due to lack of access. When we get a job taking out a back boiler and fitting new one in new location, it is seldom fruitfull for us, we are there days over budget.

Just lately I have managed to survive without doing any installs at all, because installs have been made pants by HMG. I am delighted that I am geting a reputation locally for fixing combis, it's taxing but a lot less tiring.

I didn't realise that you had to watch a program to know how to spell it.

FYI, the character of David Brent is portrayed by one of the UKs top comedians of the moment, who's also become a significant and lucrative export. If you don't know enough about current affairs to know what most of your customers watch on TV then you must be a very dull person to have fixing one's boiler.

Water flows OUT of the flow and returns back into the boiler at the return. But I would have thought that was obvious even to my Polish plumber!

The naming of "flow" and "return" is just a convention, no less arbitrary than the words "left" and "right", and just as easily could have evolved to be the "flow" from the pump and the "return" into it.

To make any assumption is an act of ignorance, and to assume that everyone has the same interpretation of ambiguous technical terms is unprofessional. Proper plumbers and engineers don't do that.

Id rather have a dull person fixing my boiler who is competant and knows what they are doing than some comedian who may not have a clue.
