Geothermal and the Environment
ETA is proud to provide consumers with the opportunity to purchase highly efficient products that are 100% environmentally friendly. Copper is a naturally occurring element that has been used in pipe form to convey drinking water for centuries. All sub-surface fluid components are deemed non-hazardous by OSHA Reporting Material Safety Data Sheets, and are deemed safe for sub-surface installation (safe for both ground and ground water) by the United States Environmental Protection Agency. Further, due to its relatively even and low operational energy requirements, the ETA system will help to reduce dependency on foreign and/or expendable energy sources, and will help to reduce electric utility brown-out and black-out concerns.
Unlike other, first generation, DX designs which utilized R-22 or a similar refrigerant, all ETA systems have been engineered to operate on the new R-410A refrigerant. Since R-410A poses absolutely no threat to the earth's ozone layer, it is one of the most environmentally friendly and safest refrigerants to utilize. Further, all R-22 (Freon) systems in the U.S.A., and in other countries adhering to the Montreal Protocol, will be affected by the upcoming phase-out of R-22. Thus, your selection of ETA's R-410A refrigerant system will eliminate this expensive obsolescence concern, which will soon present itself to millions of others.
Energy Indepence Option
The ETA DX geothermal system requires such a small amount of power to operate that the use of an ETA heating/cooling system, in conjunction with a renewable electric power source (solar, wind, hydro, etc.) can be economically feasible. Please contact ETA to discuss available options for your specific region/application.
