Default Immersion Chiller Recirculation build help?

Alright. Ive made a Immersion chiller but now want to not waste so much water. I have heard and seen people talking about Recirculation. Basically where you run the water into a cooler of some kind and use a pump to pump the water back through the chiller. I Typed the words " Recirculation chiller" and didn't find anything.

I'm sure there are threads about this. So could someone push me in the right direction to a detailed build of a Recirculation wort chiller. thanks so much

I don't have a build thread link handy, but I can tell you what I do, super easy.

I use a small pond/aquarium pump submersed in a bucket of ice water. I attach vinyl tubing from the end of my wort chiller to the output of the pump, which pumps ice water through the chiller. I direct the output from the chiller back into the ice water.

I'd recommend using the hose/tap first, until you're down to 120 or so, otherwise you're just melting ice.

Not sure if this is what your looking for but it's the way to go if you have a wort pump.

You'll get the best results if you just use water for the first part of the process (212-140F) and then add the ice and recirculation to bring it down to fermentation temperature. The key here is temperature differential between the wort and the water. You don't want to recirc the really hot chiller water back into the ice. Save that part for the second half of the process.

I use a sunterra pump its 210 gph and about 8 feet of lift. This works well.

even small fountain pumps from the big box hardware stores work just fine for this. I've got three or four for around here for small tasks.

So basically what i am getting from this is i need to waste water till it gets down to 120 then i can use the cooler/pump/ice to recalculate the water and not waste it? Am i correct

Or should i still save the hot water in another bucket or cooler to use for cleaning or making ice bags or something else later?

Any suggestions on Pump speed or Gallons per hour i should be looking for. I don't need the brightest and best but i want one that does a good job and has enough speed to cool down the wort in a timely manner.
