Got viessmann installed 2 years ago. Seems fine. Serviced regular . Last November was last one. The pressure should be between 1 and 2 , just between 0 and 1 now. I know how to increase it back to where it should be , no issue , why does it drop slowly over time I wonder ./. Works fine , thks

Can be a few reasons but generally a leak. If the pressure drop is gradual could be a very minor weep rather than a visible leak
