Geothermal HVAC

Geothermal is a dual-purpose system that can provide heating and cooling. The temperature of the earth below the surface remains relatively constant throughout the year.

A geothermal system is comprised of a heat pump, underground loops and a distribution network (such as air ducts). Learn more about the various parts that make up this energy-efficient system.

Ground Loop

The Ground Loop is vital to the efficiency and durability of geothermal heating and cooling system. It is made up of pipes that can be drilled or trenched in the backyard to connect to your home’s heat pumps. The piping will be filled with a water-based solution and circulated to absorb or distribute heat based on the requirements of your home. The temperature of the ground is constant between four and six feet below the surface, which makes it a natural source of energy for geothermal systems.

When the system is in heating mode, the heat transfer fluid absorbs earth’s heat and then carries it to the heat pump in your home. The fluid is then returned to the loop, where it starts to circulate again. In cooling mode, it utilizes the opposite process to remove the excess heat. It returns it to the loop to start a new cycle.

In a closed loop system, the pipes are filled with a water-based product and buried in the ground. The solution is safe and non-toxic for the environment. It doesn’t pollute underground water sources. The system can also use the pond or lake to provide heat transfer fluid, which is more environmentally friendly.

Both closed and open systems can be vertical or horizontal, depending on your space requirements. The vertical system requires fewer trenches than a horizontal system and minimizes disturbance to your landscaping. It is used in areas where soil depths are low or when existing landscaping needs to be preserved.

It is important to select an experienced installer regardless of the kind of system. It is essential to have a reliable and well-designed system, since geothermal systems use a significant amount of energy. A well-designed installation will ensure the durability of your system and help you save money on electricity over the long term. It is also crucial to have the system flushed frequently to eliminate any mineral buildup. This can hinder the flow of the heat transfer fluid and reduce the efficiency of the system.

Vertical Loop

Geothermal energy comes from the Earth and is used to heat or cool buildings. It is a source of energy that can be harnessed using underground loops which absorb thermal energy and then transfer it into your building. The most commonly used type of geothermal system can be called vertical ground loop. This kind of system is typically used in commercial and residential applications. This system makes use of the heat pump to transfer energy from the earth to your office or home. In summer, it operates in reverse to provide cooling.

The heat energy that is transferred from the ground to your home is stored in a network of underground pipes. These pipes are a crucial part of any geo-thermal hvac system. The pipes are made of high-density Polyethylene, and they circulate water and propylene glycol which is food-grade antifreeze. The temperature of soil or water is almost constant just a few feet beneath the surface. The closed-loop geothermal system is more efficient than other heating methods, like gas boilers or furnaces.

These loops can either be installed in a trench horizontally or inserted in boreholes that are drilled from to 400 feet deep. Horizontal trenches work best for large homes with lots of land, whereas vertical boreholes work well for homes and businesses with limited space. Installation of a horizontal ground-loop involves digging trenches, which can take a considerable amount of time and effort. The ground must also be compacted in order to ensure that the loops are securely connected to the soil.

On the other hand the vertical loop system can be constructed much faster and more easily than a horizontal loop field. The technician digs holes that are 4 inches in diameter, spaced 20 feet apart. Then, he installs the pipe to create a closed circuit. The number of holes needed will depend on the size of your structure and the energy demands.

To keep your geothermal heating and cooling system operating at peak performance, it is important to maintain the loop fields. This includes cleaning the loop fields and performing periodic testing for bacteriological issues.

Horizontal Loop

Geothermal heat pumps transfer energy between your home and ground or the nearby body of water, and not taking energy from the outside air. The reason for this is that the temperatures of the ground and water is fairly constant, in contrast to outdoor air temperatures, which fluctuate. The size and layout of your property will determine which loop to make use of. The type of loop and the method of installation employed determine the efficiency and effectiveness of your geothermal heating system.

Horizontal geothermal heat pump systems make use of a set of pipes that are buried horizontally in trenches that range from four to six feet deep. The trenches can house up to three pipe circuits. The pipe circuits are connected into an amanifold that is the central control unit of the geothermal heat pumps. The manifold sends heated or cooled water into your home’s cooling or heating ductwork.

In the beginning these piping systems were installed in vertical trenches which required a larger area to cover the pipes. As technology improved and technology improved, it was discovered that laying a single, longer pipe back and forth at various depths in trenches that were smaller could help reduce space requirements and costs without losing performance. This is the reason for the “slinky” method of installing horizontal geothermal loops.

A vertical ground loop system is an excellent alternative to a horizontal geothermal heat pump system in situations where there isn’t enough land available. It is also an option for homes located in urban areas, in which the topsoil is scarce and there isn’t any space for horizontal loops. If your property is in an earthquake-prone area and is unable to support a horizontal loop system, the vertical loop could be the best choice.

If you have a lot of water lakes, ponds or ponds could be an excellent alternative for your home. This type of system is similar to a horizontal or a vertical ground loop geothermal heating system however instead of using earth for heating and cooling it uses water to heat and cool. It is crucial to note that a geothermal system using lake loops or ponds will not work in the event of a power outage. A backup generator needs to be installed to provide a source of electricity during this period.


Geothermal heating is an efficient alternative to conventional methods. But when it comes to making the switch homeowners must consider balancing upfront costs against total savings on energy. There are a myriad of variables that play into the equation such as the local climate and soil’s composition. One of the most important decisions is whether or not to dig ground loops, or use an external tank to store hot water. The latter option may be less expensive, but it might not offer the same efficiency.

A desuperheater is an equipment used to transfer heat from a geothermal system to your domestic hot water tank. It is designed to operate during winter, when the cooling cycle of the system produces heat that is not needed. The desuperheater eliminates this waste heat and uses it to increase the efficiency of your home’s heating. It also reduces the energy use by utilizing pre-existing sources.

The best design of a desuperheater is dependent on a variety of physical geometric, thermal, and variables. These factors include the injection angle, temperature of the spray water and the nozzle’s design. These are all crucial factors that affect the performance and operation of the desuperheater.

In a climate that is dominated by heating, a desuperheater will save you up to 20% more than a traditional water heater in the summer. The desuperheater converts the energy that is taken from the house during the cooling process into heat for the hot-water generator. This allows the geothermal system to create domestic hot water for 3 to 5 months of the year, at less than the cost of other energy sources.

The desuperheater also comes in handy in the winter, when a geothermal heating system is at its lowest capacity. The device adds the extra heat produced by the cooling system to the domestic hot-water tank. This allows the domestic hot water tank to use this free energy, and increases the heating capacity of the system. The desuperheater can even be used to decrease the time that a geothermal system is active in a climate with a high degree of heating.
