Benefits For The Home
By selecting an ETA geothermal system for your home, you are selecting state-of-the art equipment providing ultimate levels of comfort and savings. Benefits of installing an ETA unit include:
- Reduce your heating/cooling expenditures up to 80%.
- Experience ultimate levels of indoor comfort.
- Improve aesthetics of your home - ETA technologies have no exposed and noisy outdoor equipment.
- Increase the re-sale value of your home.
ETA systems can typically be installed within one to two days, exclusive of interior ductwork . Each system will typically only require several trenches and/or one to two 5" -6" inch diameter boreholes drilled to depths of 300 feet or less. Once the holes have been drilled, the refrigerant transport copper tubing is inserted, and the remaining empty space is typically filled with a specially designed heat conductive and protective cementitious grout. The refrigerant tubing is hidden/buried within a trench from the borehole to the structure, where it is simply connected to the compressor unit and air handler.
When sufficient land surface area is available, the system may be mostly installed within only several trenches situated below the frost/heat line. The system is then charged with a safe and environmentally friendly R-410A refrigerant, that is not on the obsolescence/phase-out list (as is Freon/R-22), so as to be ready for operation.
The compressor unit makes about as much noise as a refrigerator when running and is typically quieter than an electric fan. There is no unsightly and noisy outdoor unit. In areas near the seashore, there is no exterior equipment subjected to corrosive salt-water air.
