Shouldn't we be looking at the longer term impacts of the alternatives considered? Although geothermal heat pumps can be integrated easily with existing systems such as forced-air or radiant floor heating, you’ll need space in a utility room or basement for all necessary components. Where there is no ductwork in place, a delivery system will have to be designed and installed, preferably one that disturbs as few original walls and ceilings as possible. For a two-storey house, for example, it may make sense to install a split system, placing ductwork and an air handler for the first floor in the basement, with a similar set-up in the attic to serve the upper floor.
Many factors will contribute to the geothermal heat pump cost that a homeowner can expect to spend during installation. When you maximize the efficiency of energy used in your home, you can significantly reduce cost and utility bills while improving overall comfort. But it is critical to evaluate the energy load and decide on ways to reduce it if you want to have maximum energy efficiency. Apart from your home’s size, other factors determine the correct geothermal heat pump for your space. Right and natural gas is a lot cheaper than electric baseboard heating. Cost is the key to any heating decision, both the payback period on the installation cost and the monthly operating cost.
Going Geothermal in Pennsylvania
Horizontal wells use a larger amount of ground area than vertical wells. Multiple trenches up to 8 feet deep and two feet wide are dug into the ground for the pipes, which are laid across the bottom of the trench. A typical system will require 300 feet of trenches for every two tons of heating load. Trees are another obstacle in existing homes because sometimes they are large and numerous. When you look at the canopy of a tree you should assume the root system under the ground looks the same.
Cost trumps touchy feely green sentiments at the end of the day. If we want more green electrical and geothermal heating, get the cost of electricity down.

However, conditions necessary for the proper function of these systems are rarely found in urban areas, as they require an abundant source of ground water and a high water table.
Heat Pumps: Ground source geothermal GSHP or air source ASHP, which one is…
This translates into a GHP using one unit of electricity to move three units of heat from the earth. GHPs also improve humidity control by maintaining about 50% relative indoor humidity, making GHPs very effective in humid areas. Horizontal ground source heat pump systems can be cheaper to install but require a significant amount of space, and it does some pretty intense damage to any ecosystems that lay in its intended path. For a given length of pipe, horizontal loop systems are a bit less efficient than vertical loop systems, as they can be more easily affected by surface temperatures. The other downside is that if or when there's a leak in the circuit, with a horizontal mat or grid style system the whole garden area has to be dug up again in search of a tiny leak that is losing the system pressure. I'm a little confused by your statement that geothermal is not a reasonable alternative for residential use, except in multi-residential or larger, and/or poorly insulated homes.
The heat pump concentrates the thermal energy and transfers it to conventional ductwork or an under-floor radiant system, which circulates the heat. In warm months, the process is reversed and the cooler fluid exhausts heat out of the house. As a bonus, the unit can assist with hot-water heating. 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.
Can you install tubing under a slab on grade foundation to extract heat in winter?
Domestic Geothermal heating systems can be a great way to heat a home, replace a furnace, and are labeled as money savers. Heating costs are going to be as good and often better than what a gas furnace can produce. Vertical loop averages approximately 10% better efficiency over the horizontal loop system. The main advantage to the horizontal loop system is that the cost of digging the trenches is generally significantly less than the cost of drilling boreholes for the vertical system.
I've been thinking about the phasing out of using fossil fuel, on and off for some time now. The only thing i'm certain of at this point is electricity is not the answer.

Using Top Drilling Companies to Assist
This will be determined upon a site visit by Ultra Geothermal. The system tonnage needed to accommodate the house can be accurately sized using the square footage of the house and insulation R-values. If the house is very large, several systems are installed that work independently for different zones of the house in both radiant and air applications.
In case if you wish to provide some warmth into a normal private house - thinking about insulation is more profitable for the pocket. Yet, when the cost is not an important option, properly installed residential geothermal heating system is a solid solution, which will free you of many standard troubles. If you think you got enough bucks in the pocket - think about it.
Some put value only in it just saying them money, while others who have lots of money may put way more value in the "green" aspect. This is primarily due to geothermal equipment being indoors and not exposed to the elements. Geothermal systems also have fewer moving parts, reducing the opportunity for malfunction.
When space is limited our only choice is to use the smaller drilling rig. We look at available land, water quality, and what the customer is looking for the geothermal to do and also the expected paybacks on the system. Each application has different circumstances and we can help you look at all of that. The ground temperature at depths greater than 10 feet remains relatively constant through the year. At a depth of 10 feet (3.04 m), the average ground temperature is 75.12°F (23.96°C) in summer and 75.87°F (24.37°C) in winter. Geothermal energy development in the UK has been limited, partly due to the lack of high enthalpy resources, but also due to the availability of cheap fossil fuels.
