If a house has all water rads, or Just one section of baseboard, but it’s not a single loop return. Do you really need to have a purge in the basement?
Only reason I am asking I went to two jobs in a row with no purging in the basement, just went to the rads and bleed the air till water came out. They didn’t even have an air separator. I elected to install both air separator and a purging station.
