Gas boiler KW question

[Agile]

Not only a good answer but to reply to a four year old posting!

If hes an ACS trainer/assessor he wont have the qualifications to join the combustion chamber probably

No problems, he can still answer my question here.

But he has not replied yet.

Assessors usually finish by 5 pm !

Admin would let him in if he can prove who he is.

You may end up regretting registering for this forum!

So EXACTLY how would the engineer measure the pressure loss from meter to boiler?

If using a water gauge then how accurately can that be read?

Taking that figure into account, then what is the accuracy of his pressure loss measurement?

Pressure loss is measured at the appliance inlet and meter test point recording readings on a U gaug. The pressure at meter may be lets say 21mb then the pressure at the appliance should be no lower than 20mb.

Some boiler manufacturers allow a lower figure but this figure must be used with caution and too complex to explain here.
The appliance must be running during this test at max rate.

I have left my license card in my assessment room. Ill sort next week.

Regards and hope you understand stoichiometric combustion.

Of course we understand it, basics although not likely going to be achieved

Wouldn't be alluding to RTP would we? .

I look forward to some hearty combustion chamber discussions with you and some of our more forward users!

I looked over my shoulder when I read that!

Take care mate join you soon!!

Absolute ******s, the reason that manus state differenrent pressure measurements at the inlet to their gas valve in working conditions is to allow for pressure losses that they will accept over their own fittings, the only way you could measure a 1mb drop over the pipework would be to insert a pressure measuring point immediately befor the gas pipe is connected to the appliance which we all know will never happen

I think you shoul re-read my post, quote "too complex to explain here"

And your reply to the above?
