Lochinvar Knight and Condensing temp vs efficiency
Is it in full condensing mode with 140 deg return temp ,with a 150 degree supply going out.. , regardless of flow rate thru it. Where do i find the actual Eff. curve for these temps.??? ( 2 stacked 400K BTU units)
Oh : the outdoor reset has picked this temp for 18 deg F outdoor temp. and I would have assumed a bigger delta T???? Thanks Paul
