Jul 27, 2021 · The allowed pressure drop when an appliance is on is 1mbar in the gas pipe feeding the appliance. 13mbar is itself way too low, its not supposed to be below 18mbar. The test port inside the appliance may be further downstream and thus have an additional loss but 7mbar inside the appliance seems excessive.

Jan 13, 2022 · A peculiarity of this boiler is that the pressure fluctuates a lot in use. Even after recharging the EV, what would happen is that the instant the boiler - and pump - fired up, the indicated pressure would drop by around 0.3 bar. I suspect this is because the pressure sensor is on the 'return' side of the pump, and this would suffer a drop

Get PriceLow boiler pressure. When looking at your boiler gauge, the needle should be between 1.0 and 2.0, if the pressure drops below this then the unit needs to be repressurised. All boilers will gradually lose pressure over time but if there's a sudden drop, then there could be a leak somewhere in the system.

Oct 26, 2020 · The boiler works if the pressure is refilled. When on water drips out of the discharge safety valve pipe. If i stop the boiler to see the current pressure then it gives a normal value for example if the boiler had been topped up and run for an hour then the reading would be 0.9 bar. This makes sense as water is being lost.

Nov 30, 2019 · If boiler pressure gauge gets to,or close,to 3 bar,when central heating has been on for a few hours, the PRV will open and allow water out to drop pressure. That's indicative of the expansion vessel not performing as it should. Possibly just needs re charging or maybe failed completely and needs replacing. But re charging to try first.

Nov 10, 2011 · The problem I have is that when we use the heating, the boiler pressure drops - and the amount it drops is proportional to how long the boiler is on - the longer the heating is on, the more it drops. So it drops from 1.1bar to 0.6bar in about 4-5 days when the heating is on about 6-8 hours a day. It stands to reason there is a leak somewhere.
