I thought I could ask here. Just did same yearly maintenance on my heating system. System is older with steel pipes and aluminium radiators. I always pressure it to 1.5 bar, but can go to 1.9 bar when hot. Temp range is between 75c to about 90c.
So question is what would really be optimal temp and pressure values?.I understand every system vary from each other but some general values would do also.
