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.
