The geothermal contractor we've made arrangements with has had a rough December with all the snow.
Drilling though snow isn't the problem. Operating a drill rig with exposed machine parts in blowing snow - that's the problem. With luck, I'll have a firm date soon on when the drill can start.
A neighbour emailed me today explaining a new local temple is having construction difficulties because bedrock is so close to the surface. That's great news. Hydraulic conductivity of fractured sandstone (the geological formation our house is most likely on) is very high.
Split rock == good water flow. Good water flow == good heat transfer. Good heat transfer + geothermal furnace == excellent heating.
