Anybody have any experience or comments on the Earthlink system for heat, a/c, and hot water? Any known problems with the proprietary Active Charge Control device?
Any info appreciated!
Any other similar systems in use?

If you do a search on this forum, you will find a lot of information (DX coil, GSHP, ...)
