: On a professional's pressure gauge, there is no marking called FINE; a pressure gauge is marked in numbers, like 2 bar, or 30 psig and has characteristics like staying steady at a certain pressure for so many hours. What is FINE to the DIY hand is too rough for professional estimation.
The pressure is 45psi to 52psi and that is well above the min for the boiler
the water flow is the same all the time with taps
open but the boiler goes on and of at intervals
of 15 to 25 sec and then stopes on for some time
only the D.H.W.
