The EPA has been considering outlawing "pump and dump" open loop systems, but using open loops that return the water back into the earth via an injection well will most likely continue to be acceptable practice. Make sure to check with your local contractor on whether there is enough water to install an open loop geothermal heating system. In most situations, the open loop geothermal systems are less costly and more efficient than closed loop geothermal systems due to the constant temperature of the ground water and the amazing conductivity of that water in comparison to the antifreeze in a closed loop geothermal system, which absorbs and releases heat through a polyethylene pipe. A typical horizontal ground loop will be 400 to 600 feet long for each ton of heating and cooling. Closed loops often carry potentially hazardous antifreeze chemicals, so building them to ensure environmental safety adds cost to the project. Do They Have Any Advantages? The reason for this is that open-loop systems alter their energy source by the extraction of water from the aquifer, that could, in turn, affect the characteristics of the ground and, eventually, result in the desiccation of the aquifer, while closed-loop systems are limited to exchanging heat with the ground (or groundwater), thus does not alter the environment. Next: Learning about spray foam insulation. The annual amount of water used by a 3-ton geothermal heat pump is about one million gallons a year. With a closed loop system, loops are placed according to the space available, and depending on your situation will be laid either as vertical loops after drilling or in a horizontal configuration. "With closed loop, we know what our costs are either way, and we've never had a problem with a closed-loop system that was installed properly.

Open Loop Vs Closed Loop Geothermal System

Geothermal heating and cooling systems are gaining in popularity because it is an economical and sustainable heat and cooling source. They can clog a heat pump system and make it inoperable in a short time. For larger installations doublet well systems are used – several for production and approximately an equal number of wells for reinjection. For more information of the different ways of designing closed loop systems check out our detailed guide to geothermal ground loop systems. Water only stays in the system for the time it takes to run through your heat pump, and then is returned. The heat is transferred first to the pipes then to the ground outside before returning, cooled, to the house. Taking Advantage of New England's Geology. These pipes either can be installed vertically or horizontally, depending on your yard. Differences in Piping. Open loop geothermal systems use groundwater, which acts as a refrigerant to transfer thermodynamic energy. Figure courtesy of Waterfurnace. Higher entering water temperatures can lead to improved efficiency of the geothermal heat pump system.

However, instead of doing a vertical loop in Florida, it's actually cheaper and more efficient for you to drill wells. Lake or pond closed loop. A closed loop system, on the other hand, requires trenching, drilling, and burying. These pipes are special buried plastic pipes that connect to your indoor heat pump. The most common are 2- and 4-pipe configurations. Horizontal Closed Loop System. This is a very large amount of water, but since geothermal heat pumps don't change the water quality, only water temperature, all of the water used by a geothermal heat pump can be safely returned back to the earth without contaminating the ground/aquifers or wasting any water. The underground loops connect to the main geothermal unit installed in your house, and is connected to your home's forced air or hydronic system. Most of the time it would be better to use a closed earth loop and forget about the inconvenience of cleaning the water coil, no matter how many years it would last between cleanings. Just make sure you consider these three factors to evaluate your site: 1) Geology If you are installing a closed loop geothermal system, the design of your loops will depend on the heat transfer rates of the soil and rocks at your site. Heat is transferred to or from the structure, to provide year-round comfort. This property was large enough to accommodate a trench for a horizontal loop system. Similar to the way a refrigerator operates, the geothermal heat pump removes heat so cold air moves throughout the home or building.

Closed Loop Geothermal Well

If you're interested in knowing more about open-loop ground source heat pump costs, just fill in the contact form at the top of this page and Greenmatch will provide you with up to 4 quotes from our trusted suppliers. This problem does not occur in an open loop, because the source water is never mixed with the discharge water, so the original source temperature stays constant. A number of municipalities throughout Long Island have either banned geothermal systems outright or taken other prohibitive measures against them. In addition, factors such as the depth of the aquifer and its extraction/replacement rate need to be taken into account. Dandelion's mixture is just 22% propylene glycol, a non-toxic, food grade antifreeze.

This is the last filter type apparatus left to catch any deposits in the water. Determining If an Open Loop System Is Right for You. The portion of the capital cost that would serve a home with a 45 gallons-per-minute open loop system would be more than $72, 000—far more than that home would pay in water rates.

Geothermal System Closed Loop

"Geothermal technology has tremendous promise as a green energy source, but open loop systems can waste enormous amounts of water from our precious underground drinking water supply, and I'm therefore proud to support this initiative, " said SCWA Board Member Mario Mattera. Heat pump furnace unit. Call us at Mosman Well Works for expert advice concerning all your well needs. Since it is a closed system, there are no harmful effects on the aquatic system. I'm finding that they're not, but only if you're looking at a five- to 10-year time frame... but more on that later. For example, if you need a 3-ton geothermal heat pump, your water requirements would be 4. Now, when a contractor tells you have a choice of two types of systems – one is probably cheaper and produces more heat while the other costs more and produces less – you do have to wonder. Wells are unpredictable by nature and water volume can dissipate or vanish at any point during a well's life cycle, especially if proper testing and planning has not been undertaken. These use a loop system that covers several square feet of horizontal ground area.

That could affect, for example, the performance of the heat exchange at the evaporator and could even damage the pump that circulates the groundwater. A closed ground loop system can be installed either vertically or horizontally depending on your yard size (To learn more about vertical and horizontal loops click here). Currently, there is a 30% Federal Tax Credit available that will help offset the cost of installation for your primary residence. Dig your trench to the water and secure it, but route the pipe even deeper after you have it submerged in the water. Open-loops have historically proliferated in geothermal heating and cooling installations and closed-loops are actually now becoming the preferred method for several reasons that tip the balance away from initial installed cost. We're here to help you understand the difference between the two! A closed-loop system is comprised of a series of looping pipes underground filled with a heat-exchanging liquid that continually travels through the pipes. One decision homeowners must make is whether to install an open or closed loop system. Geothermal heat pumps, also known as ground source heat pumps (GSHP), do just this to heat and cool homes in a highly efficient manner. Considerations: - Requires more land area than any other loop system.

Closed Loop Geothermal Systems

Rather than using straight pipe, slinky coils, as you might expect, use overlapped loops of piping laid out horizontally along the bottom of a wide trench. These use groundwater from a well as an energy source. Vertical Loop Systems. Even water which has suitable qualities could change with time to poor quality that causes problems with corrosion and scaling. The systems use an enormous amount of water—one recent application would require 45 gallons of water per minute to operate—and that water in many cases does not replenish the aquifer.

Your contractor will recommend one of these 4 ground loop designs. Lower installation costs: the installation of an open-loop ground source heat pump is generally cheaper than that of a closed-loop. There are 4 main types of loops. All this Earth heat exchange is conducted via the outdoor ground heat exchanger.
