Geothermal HVAC

In contrast to traditional HVAC systems that operate on fuel oil, natural gas propane, electricity or fuel oil geothermal offers two-in-one heating and cooling. The temperature of the earth beneath the surface is relatively constant throughout the year.

A geothermal system consists of a heat pump, underground loops, and a distribution system (such as air ducts). Learn more about this energy-efficient system’s components:.

Ground Loop

The Ground Loop is the key to a geothermal system’s effectiveness and durability. It is comprised of pipes that can be drilled or trenched in the yard 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 relatively constant between four and six feet below the surface level, which makes it an ideal energy source for geothermal systems.

When the system is heating up, the liquid that transfers heat absorbs heat from the earth. It then transmits the heat to the heat pump in your home. The fluid is then pushed into the loop, where it starts circulating again. In cooling mode, the system utilizes the opposite method to eliminate the heat surplus and return it back to the loop, where it starts another cycle.

In a closed-loop system the piping will be filled with a solution made of water and buried underground. The solution is safe and non-toxic for the environment. It does not pollute underground water sources. The system can also use the pond or lake as the source of heat transfer fluid, making it more sustainable.

Depending on the space available Open and closed systems may be installed either vertically or horizontally. Vertical systems require less trenches and cause less disturbance to your landscaping than horizontal systems. It is ideal for areas where soil depths are shallow or when existing landscaping needs to be maintained.

Regardless of the type of ground loop system you choose, it is essential to select a reliable installer. Geothermal systems require substantial amounts of energy to run and it is essential to have an efficient and well-designed system in place. A quality installation will ensure the durability of your system and allow you to save money on electricity in the long run. It is also crucial to flush the system frequently to eliminate any mineral buildup. This can hinder the flow of heat transfer fluid and reduce system efficiency.

Vertical Loop

Geothermal energy is the energy derived from the Earth that is used to heat and cool buildings. It can be harnessed using underground loops that absorb thermal energy and then transfer it into your home. Vertical ground loops are the most commonly used geothermal system. This kind of geothermal system is used most often in residential and commercial applications. This system uses a heat pump to transfer heat from the earth to your home or office. In the summer, it operates in reverse to provide cooling.

The thermal energy transferred from the ground to your house is stored in a set of buried pipes. These pipes are a key component of any geo thermal hvac system. The pipes are made of high-density Polyethylene, and they circulate water as well as propylene glycol, a food-grade antifreeze. The temperature of the soil or water stays relatively constant a few feet beneath the surface. The closed loop geothermal system is more efficient than other heating methods, such as gas boilers and furnaces.

Loops can be placed in a trench horizontally or inserted in boreholes that are drilled from to 400 feet deep. Horizontal trenches are best suited for large homes with lots of land, vertical boreholes are suitable for businesses and homes with little space. Installing a horizontal ground loop involves digging trenches, which can require a lot of time and effort. The ground is also to be compacted in order to ensure that the loops are firmly attached to the soil.

A vertical loop system is easier to install than a horizontal field. The technician makes holes of 4 inches in diameter spaced 20 feet apart. Then, he installs the pipe to form a closed circuit. The number of holes needed will be determined by your building’s dimensions and energy requirements.

To keep your geothermal cooling and heating system running at its peak, it is important to maintain the loop fields. This involves cleaning the loop fields as well as performing periodic tests for bacteriology.

Horizontal Loop

Geothermal heat pumps transfer energy between your home and ground or nearby bodies of water, and not being able to draw energy from the air outside. This is because temperatures in the ground and in the water remain relatively stable, in contrast to the fluctuating outdoor air temperature. The dimensions and layout of your property will determine which loop to employ. The type of loop you choose and the installation method used determine the effectiveness and efficiency of your geothermal heating system.

Horizontal geothermal systems employ series of horizontal pipes that are placed in trenches that are between four and six feet in depth. The trenches can accommodate up to three pipe circuits. The pipe circuits are connected into a manifold which is the central control unit of geothermal heat pumps. The manifold sends heated or cooled water to your home’s cooling or heating ductwork.

In the beginning, these piping systems were placed in vertical trenches that required a larger amount of land to encase them. As technology advanced, it was discovered that layering a longer single pipe back-and-forth in varying depths within smaller trenches could reduce the space required and cost, without necessarily sacrificing performance. This led to the creation of the “slinky method” of installing horizontal geothermal circuits.

In cases where there isn’t enough land, a vertical ground loop system is an option. It’s also a good option for homes located in urban areas, in areas where the topsoil layer is thin and there isn’t much space for horizontal loops. If your property is in an earthquake-prone region and is not able to support the horizontal loop, a vertical loop system might be the best option.

If you have a lot of water available lakes or ponds can be an excellent alternative for your home. This type of system works the same as a horizontal or vertical ground loop geothermal heat pump, but the water is used for heating and cooling, instead of the earth. Be aware that a geothermal loop system that utilizes a lake or pond will not function in the event of power failure. Installing a backup generator can supply electricity during this time.

Desuperheater

Geothermal heating is an efficient alternative to conventional methods. But when it comes to switching to geothermal homeowners must weigh upfront costs against the total energy savings. Many factors are involved such as the soil’s composition and climate of the area. One of the most important choices is whether to plant ground loops or install an external hot water tank. The latter is more affordable, but it may not offer the same efficiency.

A desuperheater is a device that transfers heat from geothermal heating systems to your domestic hot water tank. It is designed to operate during winter, when the cooling cycle of the system generates excess heat. The desuperheater utilizes this wasted heat to increase the heating efficiency of your home. It can also cut down on your energy usage by using existing sources.

The ideal design for a desuperheater depends on several physical, geometric, and thermal factors. These include the angle of injection, the temperature of the spray water, and the nozzle design. These are all factors that affect the performance and efficiency of the desuperheater.

In a climate dominated heating, a desuperheater will save you as much as 20% more than an ordinary water heater during the summer. This is due to the fact that the desuperheater utilizes the energy that is emitted from the house in the cooling process and converts it into useful heat for the hot water generator. This enables the geothermal system to make domestic hot water for 3-5 months of the year, at a fraction of the cost of other energy sources.

The desuperheater also comes in handy during winter, when a geothermal heating system is at its lowest capacity. The device can add the additional heat generated by the cooling system to the domestic hot-water tank. This enables the domestic hot water tank to use the energy that is free, and increases the heating capacity of the system. Desuperheaters are also a great way to reduce the amount of time geothermal heating systems are operating when it’s in a location with a high heating demand.
