Hi Forum,
I recently fitted a new Grundfos pump on my sealed heating system.
For some unknown reason I was having trouble getting rid of air, I would empty radiators with air returning again later, I've been repeating the task for over a week.
Last night, I was reading up on what might cause air to get into a sealed system, the only thing I found was issues with the expansion vessel...
Today, I checked the air valve on the expansion vessel, depressing it let out air, no water...
I've then depressured the heating system, put a pressure gauge on the expansion vessel, to find it had n0 pressure, it was empty...
i've repressured to 1.5bar, the factory pre install pressure, to find 1/2hr later that the pressure has dropped 1/4 bar.
I presume the vessel has gone and needs replacing?
What would you recommend as a good make of heating expansion vessel?
- There are a lot of different makes out there, the current being a Altecnic (ERES), but that's lasted only 3 years.
thanks in advance
