In most cases, Geothermal offers a substantial cost savings. In addition, it is almost maintenance free, with no equipment outside effected by the outdoor elements. There is no open flame or combustion with Geothermal, which means no carbon monoxide risk or fire hazard. Property value is increased. Lastly, the comfort of the home is greatly improved as a result of more constant heat.
Installation cost obviously varies depending on size, age, and location of the home as well as land space available. An average 2000 sq ft home with land available is generally in the range of $20,000 – $30,000.
The loop is made of high density polyethylene pipe, and will out last our life time. The manufacturer of the unit gives a life expectancy of approximately 25 years depending on run time and environment. The loop has a life span of at least 100 years!
A homeowner is simply required to clean the re-usable electrostatic filter regularly. There is no chimney, fuel lines, fuel nozzles, belts or pulleys on the system that need servicing on a regular basis.
We typically bury the pipe at a depth of 5 – 6 ft. Drainage tile is generally down 3 ft or so. If we know where the tile is located, we avoid as much as possible. If digging through some tile is unavoidable, we flag the location of any functioning tile, lay our loop lines, backfill up to the tile, compact the soil and repair the tile.
Most people will see their hydro bill rise after installing a geothermal system, unless they were heating with electric heat before the heat pump was installed. But it will only go up by a fraction of what was being spent previously on oil or propane if the system was sized, designed, and installed properly.
Sizing is done by doing a heat loss analysis on the home. Taking into account factors such as weather data for the area, insulation in the home, exposure to elements, set temperature, and number of occupants in the home.
