Randa is another one of those folks who, regrettably admit, to no location - either city or state. But for geothermal it doesn't matter- down below it's always 55° F. If you can afford the higher capital cost of geothermal, I say go for it, it's wonderful - that is if your experience turns out to be as good as ours at Liberty Village in Maryland. Very quiet, efficient, reliable, economical, and unlike conventional air source heat pumps, it produces smaller quantities of "toasty" air rather than a chilling and noisy draught. One very very cold spell in January in Maryland several years ago when I had to schedule a shut-down of the ground source (due to a sink hole!) and use the built-in electric back-up heat exclusively, my carefully metered total electric cost/day went from $4 to $14. Another substantial benefit isthat the system used the surplus ground source heat to "preheat" my (electric) hot water heater. And for further economy one has the option of turning off the electric boost
heat/backup (designed to handle the desire for rapid warm-up if you choose a warm/cool day/night mode of operation). One caveat: When we were buying (circa 1999?) there were very few contractors with geothermal experience. You have to decide how much risk you are prepared to take. We had very good experience with a small company way out in the Maryland boondocks. Our units were made by WaterFurnace. Michael Barrett now at Shadowlake Village, Blacksburg, VA where my air source heat pump periodically disturbs me with its start-up and shut-down thunks and then cools me with blasts of only slightly warm air.
I would love to get more information on Takoma Village's geothermal set up (and any one else who has geothermal). Half our buildings are too shaded for solar, and at the moment we have all electric heat. Who at Takoma Village and elsewhere would be a good person to talk to about feasibility, cost, advantages/disadvantages? Thanks. Randa Johnson New Brighton Cohousing cohoranda [at] yahoo.com
