Navien 100,000 btu heating
I was on phone with navien, my 2 workers went to the class.
Here is what I wad told when I asked him how can you get 100 K out of a pump that was only going around 5 G.P.M.
He was a nice guy I am not sure if I am saying it correct.
When there is a cal for heat and when a zone opens up the water will be pulled up the first tee as the pump in the navien also pulls the water from the cold return, so your adding them two numbers up.
He also said you need to increase the pipe size to 1-1/4, that's how it's able to accomplish 100,000 btu
He also said he preferred delta t pump because there machine operates better with a set delta t which I think they had a dipswtch for.
