3/9/2019 · When the boiler stops the pressure slowly goes down. After re-pressuring the boiler to 1.2 bars, the low "idle pressure" slowly drops and in less than a week it is down to 0.3 bars, and we have to repeat the re-pressuring. Background: The recommended pressure is 1.2 bar and the green range is 0.7 – 2.7 bar.
