Geothermal - Arcadia Drilling, Inc.




Geothermal Geothermal heat pump systems have been known for decades to be one of the most efficient methods for heating both small residential homes as well as Large Commercial facilities. There are two methods used in these systems, Closed Loop and Open Loop. An Open Loop system uses the water from a water well and after running through a heat exchanger and then the water is discarded either to a surface area or an injection well. This method is very efficient, but requires the use of potentially more than the 5000 gallon per day maximum usage that is the most any exempt well can use in accordance with Washington State Department of Ecology regulations. A Closed Loop System though is not effected by that regulation since no ground water is used, we drill a borehole to a predetermined depth and install a loop pipe and completely pressure grout the borehole with thermally conductive state approved grouting material. These loops are then connected to each other underground and then trenched over to the mechanical area of the home or office and then heat exchanger there at the furnace equipment can circulate the loop liquid, which in turn heats the building. Our Drilling equipment is state of the art, and utilizes a drilling fluid to keep the borehole open during drilling and loop installation. The Trailer mounted drilling fluid system cleans and recirculates the drilling fluid while the excess material is disposed of.
