Hi Guys,We are getting ready to install a geothermal ground loop for our home.Some of our research points us to 500′ of trench per ton of heating/cooling.Local pro’s have calculated our 3500 sq.ft. home at just over 5 tons.So we have decided a ground loop length of 2000′ using 11/4″ poly.We are here in northern Va. where ground temperatures are 55 degrees.

Any recommendations on this gound loop size or be helpful.Thanks,Tess
