I built a house recently and decided to go with a WaterFurnace Envision geo system (049 model).
I also opted for a 3-zone IntelliZone setup:
Main floor: 2100 sqft
Second floor: 900 sqft
Basement: 2100 sqft
Buffer HW tank with a natural gas HWH
On top of that I have a laptop connected to a TED (electricity monitoring device) to monitor electric usage.
Things have finally calmed down from the move and build, so I thought I would offer to post some pictures of the install, describe my usage, and let people ask questions. Not sure how helpful I'll be, but I appreciate the time everyone here took to answer my questions and want to return the favor. Any interest?
