How does one top up boiler when below 0.5bar? ...
Answers: look under your boiler within should be a braided flexible filling loop connected between the wet inlet and the heating return stretch out the tap slowly and study the gauge rise
an dont forget to trademark sure you have fully turned it past its sell-by date after topping it up as if not th boiler will walk into over pressure and dump all the dampen through the pressure relief stopcock!!
!!!!!!a thumbs down????!!!!!!! i do this for a living!!!!!???

On mine at hand is a tap underneath that I turn a partly turn. When the dial rises to 1.5 - 2.0 bar, switch it bad again. It should be between 1.5 - 2.0 all the time.
