Geothermal HVAC

Geothermal is a two-in-one system that provides heating and cooling. The temperatures of the earth below the surface remain relatively consistent year-round.

Geothermal systems consist up of a heatpump, underground loops and a distribution system. Learn more about this energy-efficient system’s components:.

Ground Loop

The Ground Loop is the main element to a geothermal system’s effectiveness and longevity. It consists of pipes that are cut or drilled in the yard and connect to your home’s heat pump. The pipes will be filled with a water-based fluid 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 surface level, making it a great energy source for geothermal systems.

When the system is heating, the liquid used to transfer heat absorbs heat from the earth. It then carries that heat to the heat pump inside your home. The fluid is then pushed back into the loop, where it starts to circulate again. In cooling mode, the system employs the opposite process to eliminate the excess heat and return it back to the loop, where it starts the next cycle.

In a closed-loop system the piping will be filled with a solution made of water and then buried beneath. The solution is non-toxic and safe for the environment. It does not pollute underground water supplies. The system can use lakes, ponds or other body of water to provide heat transfer fluid. This is also eco-friendly.

Both closed and open systems can be vertical or horizontal according to the space you need. The vertical system requires fewer trenches than horizontal systems and minimizes disturbance to your landscaping. It is typically utilized in areas with shallow soil depths or in areas where existing landscaping needs to be preserved.

It is important to select an experienced installer regardless of the type of system. Geothermal systems require a lot of energy to run, and it is crucial to have an efficient and well-designed system in place. A properly installed system will ensure the long-term viability of your system, and will help you save energy costs over the long term. It is essential to flush the system regularly to get rid of any mineral deposits that could reduce the flow and effectiveness of the heat transfer liquid.

Vertical Loop

Geothermal energy is derived from the Earth and is used to heat or cool buildings. This energy can be harnessed through underground loops which absorb heat and then transfer it into your home. The most common type of geothermal system is called vertical ground loop. This type of geothermal system is used most often in residential and commercial applications. This system makes use of an energy pump to transfer heat from the earth to your office or home. In the summer, it operates in reverse to provide cooling.

The heat energy that is transferred from the ground to your house is stored in a network of underground pipes. These pipes are an essential part of any geo-thermal HVAC system. The pipes are made from high-density polyethylene. They move a mixture of water and propylene glycol, which is a food-grade antifreeze, throughout the system. The temperature of the soil or water is relatively constant within a few feet of the surface. This allows the closed loop geothermal heat pump to work more efficiently than other heating systems like gas furnaces or boilers.

These loops can either be inserted into a trench horizontally or inserted in boreholes that are drilled from to 400 feet deep. Horizontal trenches are typically used for larger homes with lots of land available, while vertical boreholes are best suited for businesses or homes with little space. The process of installing horizontal ground loops entails digging extensive trenches that can take a lot of time and effort. In addition, the ground must be compacted so that the loops have a strong grip on the soil.

A vertical loop system is much easier to install than a horizontal field. The technician drills holes that are 4 inches in diameter, separated by 20 feet. He then connects the pipe to create a closed circuit. The number of holes required will depend on the size of your structure and the energy demands.

It is essential to keep the loop fields in good condition in order to keep your geothermal system running at its peak. This means cleaning the loop fields and conducting periodic tests for bacteriology.

Horizontal Loop

Geothermal heat pumps transfer energy between your home and the ground or the nearby body of water, rather than being able to draw energy from the air outside. This is due to the fact that ground and water temperatures remain relatively stable, unlike the fluctuating outdoor temperature. The dimensions and layout of your property will determine which loop you use. The type of loop you choose to use and the method used to install it determine the efficiency and effectiveness of your geothermal system.

Horizontal geothermal systems use a series horizontal pipes that are buried in trenches ranging from four and six feet deep. The trenches are constructed to accommodate three to four pipe circuits. The pipe circuits are connected to a manifold which is the central control unit. The manifold then delivers heated and cooled water to your home’s heating and cooling ductwork.

Originally the piping systems were installed in vertical trenches that required more land area to encase the pipes. As technology improved, it was found that layering a single longer pipe back and forth different depths in smaller trenches could reduce space requirements and costs without sacrificing performance. This was the birth of the “slinky” method of installing horizontal geothermal loops.

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

If you have plenty of water in your home lakes or ponds can be an excellent option for your home. This kind of system functions exactly like vertical or horizontal ground loop geothermal heat pumps, except the water is used to heat and cooling, instead of the earth. It’s important to remember that a geothermal system using a pond or lake loop is not functional in the event of a power failure. A backup generator should be installed to provide a source of electricity during this time.

Desuperheater

Geothermal heating is a cost-effective alternative to conventional methods. When it comes time to switch, homeowners have to balance upfront costs with total energy savings. There are a myriad of factors that come into play, including the local climate and soil’s makeup. But one of the biggest choices is whether to plant ground loops or install an external hot water tank. The latter option may be cheaper, but it won’t provide as much efficiency.

A desuperheater transfers heat from a geothermal heating system to your hot water tank. It is designed to work in the winter months when the cooling cycle of the system produces excess heat. The desuperheater utilizes this wasted heat to improve the efficiency of heating in your home. It also reduces the energy use by utilizing pre-existing resources.

The optimum design for a desuperheater is determined by a variety of physical, geometric, and thermal variables. These factors include the injection angle, temperature of the spray water and the nozzle design. These are all important factors that affect the performance and operation of the desuperheater.

In a climate dominated heating, a desuperheater could save you up to 80percent more than a traditional water heater in the summer. The desuperheater converts the energy removed from the house during cooling into heat for the hot-water generator. This allows the geothermal system to create domestic hot water for three months of the year at only a fraction of the cost of other energy sources.

The desuperheater also comes in handy in the winter months, when a geothermal heating system is operating at its lowest capacity. The device takes away the extra heat produced by the cooling system and then adds it to the domestic hot water tank. This allows the hot water tank to make use of the energy that is free and boosts the system’s heating capacity. The desuperheater can even be used to decrease the amount of time a geothermal system is active in a climate that is dominated by heating.
