Hey everyone....tomorrow I will be installing a navien combi boiler tomorrow for a customer of mine...this is for radiant in slab job....the customer ran the pex himself and buried the tubing....my question is at what temp should I be supplying to the zones....? The navien boiler will just be doing two radiant zones and dhw....I know I'm giving very little info but anything would be of help....I don't do pretty much any radiant jobs.......all I really know is from dans books.....also about the water temp can I control it with mixing valves or can I set the boiler to maintain the temp.....I will get more info tomorrow when I get the manufacture literature.....should I use manifolds? Zone valves or pumps?...I will be piping this primary secondary....thanks Paul s
