[Greenbuilding] Drilled Well to Heat Greenhouse?

[Speireag Alden]

Howdy, all.

     To keep a (strawbale) greenhouse at workable temperatures in the 
winter where the water table is only twenty feet down, under some 
rock:  what about drilling a short well and running a loop of PEX 
down into it, and then pumping water or coolant through it, and 
through loops in the floor of the greenhouse?  With ground water at 
50 degrees Fahrenheit year-round, and a pump controlled by a 
thermostat, the only power cost would be to run the pump.

     Cost would be for the well, a pump, and a solar panel to run it.

     What do you think?
