Geothermal heat pumps are typically more energy efficient than air-source heat pumps.

Answer: True
Explanation: True. Geothermal heat pumps are typically more energy-efficient than air-source heat pumps. Geothermal systems take advantage of the stable temperature of the earth beneath the surface, which remains relatively constant throughout the year. This allows them to operate more efficiently, especially in extreme weather conditions, since the ground temperature doesn’t fluctuate as much as the outside air does. Air-source heat pumps, on the other hand, rely on the ambient air temperature, which can be less efficient during very hot or cold weather. While geothermal heat pumps tend to have higher upfront installation costs, they can provide long-term energy savings and typically have a longer lifespan due to the more stable environment they rely on.

Answer: True
Explanation: These are more efficient but require more cost up front.

Answer: True
Explanation: They're not dependent on the outside air temp they use the warmth from the Earth they last longer and have less maintenance issues

Answer: True
Explanation: Geothermals use ground source heating and cooling. EER VS SEER

Answer: True
Explanation: Energy Efficiency Both geothermal and air-source heat pumps are extremely efficient. The difference between them is that geothermal uses water instead of air. Because of that, geothermal system do not have to move as much air to heat and cool and runs at 300% - 600% efficiency even in the coldest of temperatures. Alternatively, air-source heat pumps operate at 175% - 300% efficiency when it dips to very cold temperatures. Initial Cost Geothermal has a much higher purchase and install cost, but long term, lower energy costs will easily recoup the investment. You are also eligible for a 30% federal tax credit if your geothermal system is Energy-star rated. Air-source heat pumps have a lower purchase and install cost and are much faster to install. Like geothermal, they reduce energy costs but not as significantly as geothermal. If the system is extremely efficient, you can get a tax credit of up to $300. Maintenance and Lifespan Unlike air-source heat pumps, geothermal systems are all underground or indoors. That makes them safe from the elements and any possible vandalism. They typically last approximately 25 years. Air-source heat pumps require regular cleaning and maintenance and are easily damaged and last around 15 years. Space Requirements Deciding on which system is best for you may simply come down to how much room is available. If the area is small or has expensive landscaping, geothermal may not be a good fit as it requires extensive excavating. Air-source heat pumps are much smaller and do not require as much space.Geothermal and air-source heat pumps are excellent options when it comes to home heating. They are both extremely efficient compared to standard forms of heating and are relatively clean sources of energy. With either system, you know you’ll be making a great choice for an efficient, long term option to heat and cool your home.

Answer: True
Explanation: Useing the earth tempature to cool down or heat up is way more efficient. The air temperature isn't always as constant, as where the ground stays same.

Answer: True
Explanation: Air to air heat pumps use the heat from the ambient air as a trasfer point, while the Geothermal system uses the more comstant temp of the earth as its transfer medium.

Answer: True
Explanation: Most geothermal are about 40 seer efficient and the best you can get out of her old air heat pump is 20 -25 seer

Answer: True
Explanation: As with any heat pump, geothermal and water-source heat pumps are able to heat, cool, and, if so equipped, supply the house with hot water. Some models of geothermal systems are available with two-speed compressors and variable fans for more comfort and energy savings. Relative to air-source heat pumps, they are quieter, last longer, need little maintenance, and do not depend on the temperature of the outside air. A dual-source heat pump combines an air-source heat pump with a geothermal heat pump. These appliances combine the best of both systems. Dual-source heat pumps have higher efficiency ratings than air-source units, but are not as efficient as geothermal units. The main advantage of dual-source systems is that they cost much less to install than a single geothermal unit, and work almost as well. Even though the installation price of a geothermal system can be several times that of an air-source system of the same heating and cooling capacity, the additional costs are returned to you in energy savings in 5 to 10 years. System life is estimated at 25 years for the inside components and 50+ years for the ground loop.

Answer: True
Explanation: Installation is more expensive

Answer: True
Explanation: This is true due to a geothermal heat pump uses heat from the earth to heat your home.

Answer: True
Explanation: the convection medium is at a constant temp and usually at a greater delta T

Answer: True
Explanation: Geo thermal uses the water underground to absorb the cooling by product of the heat pump. As the outdoor air temperature drops the efficiency and capacity of an air source heat pump also drops. The water temperature in the ground remains more constant and is not effected by air temperature drops

Answer: Not sure
Explanation: I don't have enough evidence

Answer: True
Explanation: more heat available
