Hi everyone: I've just got my 1st chiller used off e-bay and was wondering how members have hooked them up. I checked with set-up at Active Aqua chiller & they show 2 pumps both in res one to circulate the grow & another pump for chiller & chiller returns & feeds from res tank. The chiller I got is a 1/6 horse & has low demand of 180 gph and max demand not over 600 gph. I was figuring to use a 400 gph pump which would be able to circulate my 47 gal res 8.4 times in an hour but I was going to run the chiller in series with the grow (pump water from res to chiller & output of chiller feed plants & return is again pumped through chiller) but the commercial set-ups show the use of 2 pumps, both in res tank, one to circulate & 1 for chiller that return directly to res tank from the chiller.
It just sounds strange to use 2 pumps (which both generate heat) and it seems your pumping just cooled water back into chiller, to some extent, without passing through plants 1st. Any help here will be greatly appreciated.
