Geo systems extract stored solar energy from your property. The Earth is a free, can I repeat that, a free solar energy system right beneath your feet. Granted, it’s not as efficient as some current high tech systems, but it’s free. We can extract this free energy with heat pumps. This is how we can claim efficiencies of 400%. We’re not buying this energy, it’s energy we already own. Geothermal / geoexchange systems are simple yet complex. They are nothing more than an application of the laws of physics. There is no witchcraft or techno-magic involved. The complexity arises because the designer and installer must understand pumps, compressors, electrical systems, controls, measurements, site assessments, and many other factors. By comparison, a gas-boiler requires a gas connection pipe, a chimney, and a circulator pump to connect it to the piping and a plug on the wall to plug it into. It’s that simple. A Geo system requires an accurately sized ground loop, critical flow rates through the ground loop and the heat pump and critical flow rates on the load side be it air or water. Good controls are important and methods to measure all the flow rates are vital. Accepted industry practices are not adequate and must be improved. Because the system is site-built instead of unpacked from a box, the selection of components and the care of installation is so important.


  • The most useful renewable energy system
  • The most comfortable
  • The most reliable
  • The most efficient
  • The most simple (when you get it right)
  • The most everything in an hvac system
  • The most expensive to install (sorry, can’t have it all)


  • The most useful because dollar for dollar, geo outperforms solar, wind, air source heat pumps or whatever else there is in the entire renewable energy sector. plus, it’s available “on demand”.
  • The most comfortable because it works as a low energy system that delivers appropriate levels of heating instead of the high temps that go straight to the ceiling.
  • The most reliable because all the parts are warm and dry in the mechanical room.
  • The most efficient because the COP is the highest of anything. Forget the 90+% eff that the burners of dead dinosaurs brag about when you can have 400+% eff from the dirt below you.
  • The most simple because there are the fewest moving or replaceable parts. 1 ground loop pump, one compressor and 1 fan or circulator pump on the load side. Oh yeah, there’s a thermostat too.
  • The most everything includes the least service calls, the longest life span, the least co2 emissions, and the most capable in that it can be used to move energy in a commercial process or do simultaneous heating and cooling.
