Installing navien npe-a on house without dedicated recirc. So I want to have a recirc system. Does the npe-a need a dedicated recirc? It is a possibility as we are doing a remodel… I know the npe- a has an internal recirc but what do I do to make this work the best and most efficiently?

Plan on installing a full recirc. loop. If PEX, then 3/4" is required.
The most efficient system is to utilize the Hot Button system and have all relevant spots trigger the pump only when desired.
Only licensed professionals should be installing.
