The next year after a very high (3ft piled) rough back-filling of a 7 ft deep Earth-Coupled-Loop-GeoThermal (ECL, gle) trenched 4-5ft wide. Already below 1ft high , still settles into a couple of years for final landscaping, or one can order "compact fill" to even out quickly at the time of installation. Trenched loops are just as "low-impact" to the Earth as any drilling and headers, Terms such regarding the "impact" of what is only COMMON excavating only really impact your wallet. There are myths of "Guerrilla-Marketeer" salespeople promoting expensive drilling over less costly excavating.
(Only when excavating and landscaping misses your criteria, then should one consider drilling: i.e.) from too rocky in shallow ditches, or too dry, not enough space, and only a few other reasons.)
TWO) 2ft or 3ft wide -or ONE) 4ft wide excavation, assembled with up 6 x 3/4" GT-pipes x 245-to-290' trenches:

Heating and Cooling Loads will vary, but CAN BE PERFORMANCE GUARANTEED of the ECL Piping flow rates and entering temperatures. The loop installers must eventually be responsible for selling BTUh's of Thermal Energy Transfer as Engineering moves towards merely putting the BTUh's in a specification, rather than each person guessing at a good design. Clauses of cost-related additional GT-Piping-Systems-Installation (GTPSI) can and must more regularly be instuted sooner than later:
GEO.Pros, JP has the GUARANTEE.
