I have a Condensing gas fired wall mounted boiler does DHW, radiant floors as well as central heat
The brand is Baxi Luna 1.330 Recently I have noticed the gauge on the front of the unit has been indicating higher pressures. (I not even sure what it measures)
range of the gauge is 0 - 4 bars with the operating range (green area) 1 - 1.5 ish.
Although everything seems to be operating fine the gauge is showing well into the red at 4 +
I am hoping to find the cause of the high reading. Possibly a failed gauge ?
Any advice I can get before calling some on in would be appreciated. I don't want to find the basement full of water
