Is geothermal worth the money?
Second, yes geothermal is worth it over propane. When we compare fuels the best apples to apples way to compare is the cost per 100,000 BTU's of heat. For example, if propane is at $2.00 a gallon and there are roughly 91,000 BTU's of heat in a gallon of propane and you are using a 95% efficient furnace it costs $2.31 for 100,000 BTU's of heat.

Does geothermal heat feel warm?
The temperature in the ground where the heat pump's refrigerant loops are buried remains far above freezing all the time, no matter how cold the weather is. This makes geothermal heat pumps the most dependable type of heat pump when it comes to providing steady warmth.
How does geothermal heat above 55 degrees?
A heat pump in heating mode is basically an air conditioner running in reverse. At the primary heat exchanger, the system accepts heat energy extracted from an external source, in this case the 55-degree fluid circulated from the GHEX, and transfers it to frigid refrigerant vapor that absorbs heat very efficiently.
How much heat can you get from geothermal?
Credit: Patrick Laney, NREL 13104 Direct use geothermal systems use groundwater that is heated by natural geological processes below the Earth's surface. This water can be as hot as 200°F or more. Bodies of hot groundwater can be found in many areas with volcanic or tectonic activity.
Does geothermal heating work in cold climates?
The answer to this is yes, geothermal heat pumps can and do work just fine in cold winter climates. This is possible because while we experience a huge change in temperature above ground as the autumn leaves turn to snowflakes and ice, the earth just a few feet below is unaffected.
Can geothermal pipes freeze?
If a loop pipe, a loop fitting, the loop pump assembly or any other 30 degree cold surface in the home is left exposed, it will first condense moisture and then the moisture will freeze or at least frost over. This is normal and should not cause any problems with the operation of the geothermal heating.
What is the life expectancy of a geothermal system?
Geothermal heat pump systems have an average 20+ year life expectancy for the heat pump itself and 25 to 50 years for the underground infrastruc- ture. Additionally, they move between three and five times the energy they consume between a building's interior space and the ground.

If your geothermal HVAC system is blowing cold air on a frigid day, the emergency heating system may have an electrical problem, such as a malfunctioning capacitor.
How does geothermal get heat?
A furnace burns fuel to create heat, whereas a geothermal heat pump exchanges heat between the ground or water source and the air to heat the home. Because the temperature below ground stays constant around 50 to 60 degrees year-round, it can be used as a heat source.

Is geothermal energy only available in certain areas?
Further, a common misconception about geothermal heating is that it is only available in specific geographical locations. While regions close to volcanic activity (often found along tectonic plate boundaries) have a higher output of geothermal energy and are often host to utility-scale geothermal electric power plants, homes anywhere can take advantage of residential geothermal technology to heat and cool their home at low cost with very few emissions.
What is geothermal energy?
This is the basis for an unvarying source of energy that can heat your home. Geothermal heating exploits the latent heat energy in the earth to provide warmth without natural gas combustion or electrical heating.
How deep is geothermal water?
This arrangement, known as a ground heat exchanger, may be installed in a horizontal configuration at an average depth of 5 feet or buried vertically in deep bore holes. A heat-absorbing fluid similar to anti-freeze is pumped through the network of tubing. As the liquid circulates, it absorbs the latent heat energy present in the ground year-round. The warmed fluid is conveyed from the loop field to a heat pump located in a sealed compartment inside the home.
How does a heat pump work?
The warmed vapor is then conveyed to a compressor that concentrates the molecules of heat energy in a vapor compression cycle, raising the temperature of the vapor to approximately 120 F. This hot vapor passes through tubing in the secondary heat exchanger installed in the ductwork, which functions as a condenser that sheds heat as the vapor condenses back into liquid. Air pulled over the heat exchanger is heated by this shed heat, then dispersed into the ducts to warm the home.

How does geothermal cooling work?
In summer months, geothermal cooling functions in a similar way to standard air conditioning, only heat is not simply ejected into the outside air, but rather deposited deep in the ground for future use.
How much does a geothermal system cost?
Ball park pricing for a geothermal system: For an averaged size home (2000 sq. ft.) a GSHP will easily cost $30,000 to have installed, and that is in exchange for a monthly saving of about 50% on the heating bill. So payback for the average single family home is simply too far away to make this a financially competitive option with all but the highest consuming homes - and even then only when the boiler or furnace has failed and needs replacement.
