Chiller on the overflow possibilities

[Bugger]

Do any of you have your chiller plumb to the overflow or are you running it on the return pump. Do you find your pump is not pumping much flow

I run two returns. One is the usual and the second is from 1st chamber to chiller and then to DT.
I had to dial down my main return to minimum and keep the pump supplying the chiller at minimum, as my 32mm drain was not able to cope with the flow.
Pumps Jebao DCS 4000. Chiller is Teko 1000

I had a recent thread on this same topic. Ended up deciding not to use the drain as chiller feed.
