Hello
We recently had the CH system in our (large-ish) old Victorian house converted from open to closed system.
I have noticed that the pressure gauge (next to small red metal tank which was added as part of change) often falls below red warning needle (set at 1 bar) when heating is off.
When heating is on the gauge reads between 1 and 2 bar.
Is this normal ?
We regularly get air in one particular radiator on ground floor, (immediately above the boilers - these are in cellar), so this needs bleeding quite often. This issue pre-dates the change over to closed system.
Are the 2 issues connected ? If so what can be done to fix this ?
One plumber suggested putting in something to fill leaks and then possibly a power flush to remove corrosion / sludge.
There are no obvious external signs of leak in the CH system.
Thanks
