I was told by a guy with 35 years of hydronic heating experience that if you pipe the supply from the boiler to the bottom of the hydraulic separator and have the return on the top, but have the supply with pump to the field on the top port of the hydraulic separator and the return from the field on the bottom, that it would work just fine. He said that there is not enough mixing going on in the separator to effect the temperature by more then a couple degrees. Any thoughts on this?
The reason I am asking is because the idronics manual says to only pipe supply to top and return to the bottom. Sometimes the piping would be nicer looking to the eye if i could bring the supply into the bottom.
