Open loop geothermal heating and cooling. Well water is used to heat and cool the house and then it's discharged into the pond.

I wish I had closed loop. It would be more economical as the well would not be needed. Not sure I could afford to modify it though but I may do some checking.
My main concern right now is the clogging of iron and carbonates in the discharge line. Its seems to flow O.K. though - at least for now. My local plumbing supply said they could run a benign chemical through it. I will see how much it costs. Now may be a good time with the pond down and fish out. I almost wonder if I could do it myself. Shut the furnace down and cap the end of the hose temporarily. Then run in muriatic acid and let it sit for a little while. Then crank it back up.

Is that a good price for propane? With all the natural gas developing in this country you'd think the price would go down?

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
