This gauge helps the operator to determine if the boiler is properly filled with water and if the expansion compensation in the system is operating. A thermometer.
For your central heating system to go from one and a half bars to zero you would have to loose an approximate 1 pint to 2 litres of water. This also depends on the capacity of the central heating. The pressure release valve which if turned can lose the pressure from the boiler.

Feb 08, 2015 · Since October last year, I have had the central heating on daily, averaging about 12 hours a day. In December, I got up one morning to find the boiler flashing the fault display 'E1 19' and, after consulting the User Guide I topped up the water pressure to one and a half bars. This was fine for 3 weeks after which the fault returned.
