Update - June 2014

Not much has happened, the house is in need of repairs before I can decide to upgrade our energy system.
I just looked at heat pump forced air systems, and they are advertised to cut 30 to 40% of an electric bill, which seems low and pushed the ROI to beyond 10 years. So I am still considering a hydronic system that can use solar. It really seems a hydronic system is the best, with combined heat pump and solar heating.
Starting with the hot water system would also be a great way to learn how to build the heating system. A good first project would be the hot tub system.
