Here is another idea, ; You can use this kit from eBay, http://www.ebay.com/itm/New-Version-...item20e5c235f3 to place a 2L soda bottle in your sump and, pump cold water through it and use it as a cooling "coil/heat exchanger". The walls of a 2L soda bottle are thin and providing your cold water temp is below 15C it will help your chiller a lot. This is still cost effective $18 with free shipping. Instead of buying 200 feet of tubing. I did not try this, myself, but looks very promising. jmtcw. |

I'm surprised that nobody mentioned using ground source cooling. Think of a ground source heat pump in reverse. Would cost you zero to run and is the greenest of all options. Simply t-off of your return pump and run it out to cooling coils buried out in your lawn and then back into your sump. There is actually a chapter in j Sprung's books on how to do it.
