Yes, ideally 3 variations in flow temperature, ufh 35 (most efficient temp for my ufh), rads 55 (what I believe most efficient for my boiler), hot water 65 (because we have to kill stuff).
I was coming across some posts about priority...
Thanks,
I did call vaillant, as I have an old ecotec plus, but they said no such tech available for their old or even their new boilers.
I was thinking there has to be a solution out there somewhere, hence the post, as I have searched...
Ideally I would like ufh to run at 35
....but with current flow rate set at 75, the boiler aims for 75 and gets there way too fast! and overheats as the 35 mixing valve blocks most of the heat, the boiler does not like that as it over...
