Gas supply for Vaillant 937 / Copper or Plastic

15degrees and 1013mbar are standard atmospheric temp and presure at sea level.

Used to use these figures to calibrate altimeters.

I appreciate having an altimeter in my car, but at the same time it has to be said this is unusual :rolleyes:

Are we saying its a must have instrument for heating engineers tool kits. ;)


psssss, I wonder if you could use an attitude gauge for leveling pipes etc :rolleyes:
 
Why have you got an altimeter in your car :confused: and do you alter the daily pressure to keep it accurate. ;)

Maybe if he OP lives up a large hill and its always cold he might need bigger pipe. :LOL:
 
Hi all again, to answer the question I am looking at about 5 X 90 degree bends in the pipe, and to the other question the corgi guy told be to run 2 lots of 28mm in parallel up to the loft.
Thanks to you all.

So much for CORGi then. Was he a real Corgi man?
 
12m + 5 bends = 14.5 m

15m will deliver 7.2m³/hr with a 28mm pipe, more than enough.

The cooker and fire may alter it but we would need more details

Because it's a Pajero and comes complete with an attitude, altimeter and compass.

And no I don't alter it unless I'm hill climbing. :eek:

Will it take off though? On the famous conveyor belt I mean, of course.
