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. We advise to always have the strainer before the heat exchanger, but in many closed loop systems the only critical design factor is that the strainer be before the pump. In summer, the process reverses as interior heat is removed and dispersed back to the earth or water well. In that sense, heat pumps are divided into two types: air and ground. Slinky coil ground loops are essentially a more economic and space efficient version of a horizontal ground loop. Is ground water not a loop? Horizontal Ground Loops. Drilling well for closed loop. First of all, the closed loop system is an easier system to maintain and will last much longer because it has fewer moving parts and is less dependent on the many factors that go into an open loop system. This often limits their use to coastal areas, and areas adjacent to lakes, rivers, streams and abundant aquifers. Afterwards the water is reinjected back to the aquifer via a second well (figure 1). • Because much of these systems are located underground, their maintenance is extremely low beyond filter changes and periodic checks.
One of the main benefits of the open loop system is they tend to be the most efficient means of geothermal heating. Understand the Advantages and Disadvantages of Both. Making it the cheaper option in terms of installation. Cost: Because open loop systems require no trenching, drilling, or burying hundreds of feet of plastic pipe, open loop systems are the simplest and often cheapest type of geothermal to install. The groundwater is pumped through your heat pump, and the heat from the water is either extracted (in winter) or rejected (in summer). When our heating contractor Tony Silverio told us we had a choice between a closed loop and an open loop geothermal system, our first inclination was simply to go with the least expensive. These systems can use closed loops that circulate water or antifreeze inside a completely closed system or open loops that draw water in from a well or lake and discharge it into a second well or back into the lake after it has run through the system. Also, make sure the end of the pipe is unrestricted so the used water can be expelled without barrier.
In closed loop systems, water cycles through extensive underground piping systems to cool or heat your household. If you are considering a geothermal system, you have probably heard the terms "closed loop" and "open loop". Closed loop: Closed loop systems are used in both ground and water-source applications. If you have an existing well, how deep is it and what is its flow rate and static water level? There's a lot to like about geothermal heating and cooling. With open geothermal ground loops, rather than continuously running the same supply of water or antifreeze through the system, fresh water from a well or pond is pumped into and back out of the geothermal unit.
The water may also be directed into a local pond or approved drainage ditch, depending on local codes. In warmer climates, during cooling mode, the water flow rates may need to be increased so the geothermal heat pump's efficiency will be acceptable. Open loops depend on an adequate supply of incoming water and adequate disposal capacity for outgoing water, so changes in well deliverability can be a problem. Over the next 10 years, Ray found that about half of the dozens of early open-loop systems he helped put in "had major problems. When air conditioning is needed, the process is reversed. The most typical geothermal installation utilizes a closed loop system.
A typical horizontal ground loop will be 400 to 600 feet long for each ton of heating and cooling. On the other hand, the continuous extraction and release of water that takes place in an open-loop ground source heat pump cannot guarantee that optimal water conditions are met. This actually makes the A/C more efficient. We're here to help you understand the difference between the two! Federal and provincial governments recognize the important role that geothermal plays in reducing home energy use, and have created rebate programs to facilitate installation. An open loop system utilizes water from a drilled water well and involves no artificial solutions. The minerals and particulates in an exposed water source with animal and plant life can decrease the efficiency of your heat exchanger. The other thing of note in an open loop system is to install the pipe strainer on the supply side of your geothermal line. Greenmatch services are free and there are no hidden obligations. Water in deep "standing column wells" is the medium of the heat exchange between the earth and your home. MUSE at "EGU2020: Sharing Geoscience Online" – Free online geoscience conference. Supplemental/auxiliary electric heater. As the fluid circulates underground it absorbs heat.
Many homeowners are unaware of these regulations and are taken advantage of by installers who do not obtain the necessary permits. The water may then be re-directed into a local pond or drainage ditch. Best for: - Rural areas where space permits; areas where soils can be easily excavated; land with high moisture content is optimal for these systems. Closed systems use a continuous loop where the heat transfer fluid/water is continuously circulated. Skipping this important step could lead to major issues down the line. Vertical loops are generally more expensive to install, but require less piping than horizontal loops because the Earth's temperature is warmer and more stable farther below the surface Vertical loops typically require 150-300ft 6 inch boreholes with 300-500ft of piping per ton.

A closed-loop system is more reliable and requires less maintenance in the long term. Do They Have Any Advantages? Dandelion's mixture is just 22% propylene glycol, a non-toxic, food grade antifreeze. The main costs of pumping well water are how far it must be lifted up against gravity, and the type of motor used in the pump. In order to customize your system for your site and your home, we work closely with energy distributors and manufacturers of geothermal heat pumps. Then, about 15 years ago someone invented the closed-loop system.
