Hi. We've got a Vaillant Ecomax 824/2e Condenser Boiler.
The pressure gauge went down almost off the green, so i re-pressurized to between the top and bottom of the green area.
When the heating came on the pressure went up higher than i'd seen it so i reduced it to 2bar. When the heating cooled down the pressure dropped back down to below 1bar.
I have a thought that there might be some air in the system.
Any ideas?.
