Errands in the Big City (or what passes for a metropolis in Vermont).  En route, stopped in Vergennes to meet (very briefly) with Sean at the Goose Creek office, then at length with Dennis Senesac at Ryan’s to talk about the house HVAC design.  We did a back-of-the-envelope heating load calculation based on -9°F outside temperature and 70°F indoor temperature, which showed that a 3 ton geothermal heat exchange system would produce about 10% (3,000 BTU / hour) less than the heat energy required.  However, given that we also will have a 15,000 BTU / hour woodstove and emergency electric resistance heating available, we’ve decided to go with installing a 3 ton system, rather than step up to a 5 ton system, which is the next available size.  As soon as the 72 hour well capacity test is complete, Dennis is going to order the major HVAC system components so that he can figure out how to get that 10 pounds of “stuff” into the 5 pound sack represented by the Utility Room dimensions.  Picked up Alverta at her Residence, retrieved my compressor from Burlington Tool, got the special garage floor sealer at A.H. Harris Construction Supply, then headed for Calais.  We enjoyed a nice lunch and visit with Steve and Mary, and I also picked up 3 gallons of maple syrup from my supplier, Paul Orlander.  The black flies were horrendous!!!!  After helping Alverta do some grocery shopping, arrived back at Fern Lake at 5:30, where the mosquitoes were still out in droves.
