mix valve sizing question

Member Posts: 1
trying to size a mix valve for 26 unit house.
stick with the 1-1/4" size or go bigger?
how is the watts n-170-m3?
recirculation pump necessary?
some units have 1 bedroom and some 2 bedrooms) but each unit contains 1 kitchen, and 1 bathroom (with faucet and shower).
pipes coming in and out of the tankless coil are 2".
cold water supply is 1-1/2"
return pipes are 1"
existing mix valve is 1-1/4" (old taco model # 587-1).
federal steam boiler, #2 oil, hot water comes from the tankless coil
need enough hot water for about 100 people (give or take, plus some have portable washing machines).
stick with the 1-1/4" size or go bigger?
how is the watts n-170-m3?
recirculation pump necessary?
Thank You In Advance.
