The boiler should read between 1 to 1.5 bar of pressure when the central heating is cold. If this drops too low, below 0.5 bar for example, this normally means water has been lost from the central heating heating system and the filling loop must be used to replace this water. When the central heating is on, the pressure may increase on the
