Boiler Pressure Issue

Member Posts: 1
In the attached photo, you can see a view of my boiler and plumbing system.
I've been dealing with an issue of increasing pressure in my boiler for the past few weeks. Normally, when all the valves are in the down position, the pressure increases to around 0.5-0.75 bar every night. I manually reduce the pressure by releasing water from the discharge valve.
Unfortunately, most technicians in Turkey are untrustworthy and charge exorbitant fees. So, I want to gather as much reliable information about my boiler issue before needing their services. That's why I'm turning to this forum for advice.
I've conducted several tests, and when I closed the valve on the right in the photo, I noticed that the pressure didn't increase. In my online research, I read that pressure increase issues could be due to a faulty heat exchanger, valve leakage, or expansion tank problems.
How can I determine the root cause of the problem? If the pressure doesn't increase with this valve closed, could replacing it solve my issue?
I appreciate your assistance and thank you in advance.

Could be the expansion tank is bad? Do you have a manual for the boiler, or look it up online. Is it a Ferroli boiler? A UK brand?Bob "hot rod" Rohr

You should probably run the pressure at about 1 bar.
There are usually 1 of three issues:
Bad expansion tank or a loss of air charge in your expansion tank
Leaking pressure reducing valve or make up water valve
Or possibley a bad heat exchanger if the boiler also heats domestic hot water.
The boiler Name and model # would help.
Not knowing more about your boiler and your system it is hard to make any recommendations.0 -
It seems to be a heat only unit . There is a pressure reducing valve in that unit . Not sure if there is an adjustment on it . It could be dirty or need of a replacement .
There was an error rendering this rich post.

Does closing the white valve on the right also close off your domestic water? Or hot water? Or is that separate?Br. Jamie, osb
