no pressure system
the no pressure system has a resevoir mounted above the circulating pump where the air can escape from the closed loop system. This eliminates the need for a flush cart when filling a closed loop. The level can be monitored through the sight glass and refilled with a hose if it gets low. WaterFurnace just unveiled their new design and it looks like it will take care or a lot of problem loops where air just seems to never get flushed out and takes out a pump now and then

I typically spec. a 150 ft deep well per ton, all connected to a reverse return header grouted form the bottom up with thermally enhanced grout.

If I have space, I always do a horizontal loop with a backhoe. The results always seem to be better for cheaper, and the variables can be seen with the naked eye. Its hard to tell what is happening with a bore hole hundreds of feet below the surface
