ground source and hydronic cooling recommendation [RE-wrenches]

Hi Kurt,
You are headed in the right direction.
With the pond you can use a water to water heat pump.
There are cheap commercial units used in big buildings with a zone in 
each office.
Tetco, Hydroheat, Florida Heat Pump and Waterfurnace all make water to 
water units that are quite good. If you are concerned about sludging 
(mud and debris)  the heat exchanger they all have designs for HDPE pond 
loop heat exchangers that work quite well. It is easy to overheat a 
small pond, but half acre if deep enough will do nicely for a house. Do 
check the manufacutrer guidlines for pond loop systems.
Edwards was offline for about six months, but Tom Delinger at Tetco 
bought Edwards and has reorganized the company. He really knows this 
stuff and has been very helpful with projects I have brought to him in 
the last year. Western Nevada Supply has access to Hydroheat and Tetco 
products, and should also help you with the HDPE pipe and fittings 
needed for the pond loop. Let me know if they canot help you. I still 
have a Hydroheat binder but the whole package is at 
http://www.hydrodelta.com/main.shtml 
and the Tetco stuff is at 
http://www.geoproducts.com/ .
