We’ve got a functioning geothermal HVAC system running! They finished up the piping from the exterior wall to the furnace.

I was rather excited to see the containers of methanol — filling the tubes is the last step before bringing the system online. I like a nice fire … but it’s a cold way to heat your house.

The loop filling contraption – hooks up to the domestic water supply, mixes the methanol, and pumps it into the loop field. Over a hundred gallons – since we know the diameter (3/4″ in the loopfield, 1.5″ to the house) and the length (8x 200′) … we’ll calculate the volume of the cylinder some day. But for now … we’re got HEAT!!!
