ok, this might sound crazy, but it's worth a try...watch out John...Fakrgyver is here!
Purpose: use my chiller in the garage in the winter without having to run a garden hose from my outside tap into my garage. It would also resolve the need for 2 buckets (one for cold water the other to drain the hot water).
Create a closed water system to flow through my chiller.
Parts:
1 x impeller pump (already posted the pics)
1 x keg sealed and filled with ice water
2 x 10' lengths of garden hose.
1 x 3' lengh of garden hose.
1 x 50' spool of 3/4" copper tubing (used during a previous fakrgyver build of a pool heater for a $79 wallmart 12' pool)
Hook the pump up to the chiller's intake. Hook up 10' garden hose from chiller exhaust, run it outside and attach it to the input of the 50' copper spool (shoved in the snow). Attach the output of the 50' copper spool to the IN valve of the keg. Attach 10' garden hose to the OUT valve of the keg and attach it to the inlet of the pump....
Make sense? this would in fact create a closed loop for the water to transfer through. the hot water leaves the chiller and goes through 50 feet of copper buried in the snow, then dumps into the ice water in the keg, then is fed back into the pump...
