We are building a house and I need to figure out if a pump is needed between the storage tank and the the mechanical board to supplement the Circulators for each zone.
If there are some good articles on how to calculate it I would appreciate it. Or, if there are suggestions I also appreciate that.
We have 3 zones downstairs and 4 zones upstairs with varying total lengths due to area size. All loops are less than 275 for 1/2" pex.
The largest zone has 1100 linear ft and the smallest has 180 linear ft. Total linear ft for all zones is 3800.
I am thinking of the Grundos Alpha2's for the circulators.
The 37 gallon Storage Tank will be in the same 6x9 room as the circulators.
Thoughts?
Thanks,
Dean
