Hi,
Looking for some help with an ongoging problem, it's a sealed system with seperate expansion vessel prv etc. Top pressure up to 1.5bar with system cold. pressure rises to about 1.8bar when running as expected but over next few days cold pressure slowly drops to zero, but still rises to 1.8bar when running. System never stops running due to low pressure. Have changed exp vessel prv and gauge to no avail. checked for leaks and found none, but don't think that is an issue as it never needs topped up anyway.
Any ideas???
