I'm trying to work out the current gas pressures in our house prior to
getting a new boiler (to make sure the current pipework is suitable).
Looking at Ed's FAQ, I should be able to put a manometer onto the meter and
find out the pressure there - however I can't see any such test points.
I've got an old governor on the input side of the meter and can't see any
test points on there. The meter is a reasonably new BTR Eurometers Ltd made
digital one. The output from the meter has a screw thing (about 5mm
diameter) on the output collar - though I don't want to unscrew that unless
I'm sure I know what it is.
As I understand it, the pressure from the govenor should be 20mbar +/-
1mbar - however the Ideal Classic SE boiler claims "a *minimum*
of 20 mbar MUST be available at the boiler inlet, with the boiler operating.
So before any pipework runs are taken into account, my pressure may be to
I'll check the pressures at the current boiler and see what's there. I
really don't want to be doing any new pipework as the pipes run under the
kitchen floor and behind the kitchen cupboards....
Incidentally, where's the best place to buy a manometer from? I've seen one
online for about £15 + VAT (glass) and cheaper for plastic. Any preference
as to which to get assuming I'll probably neverUID it again - or at least,
not for a while.
