How to Install a Geothermal Heating System?

Geothermal Heat Pump System

The geothermal home system is a system that uses geothermal energy to heat and cool homes. It functions as a freezer, a tubing center hidden in the bottom of the soil, it expels that collects heat from the surface. This device has a fluid and decreases energy consumption in the same manner as traditional coolers by around 70%.

The temperature remains consistently high, regardless of climate change, as you know in the center of the earth. This system utilizes the ground layer where the temperature remains fixed at 50 ° C; this pump offers a reliable solution to your energy needs.

The machine has many benefits, it only requires some maintenance. It is promised for ten years and operates without problems for decades. It makes no noise. For 2000 square feet it took 1500-1800 feet of tubing. But what about installing this system, how to install a geothermal heating system.

Selecting the Geothermal Heat system

Do not ignore the following things if you want to use a geothermal heating system:

Geothermal Heat Pump’s efficiency

All ground and water-source heat pumps are power effectiveness shown by their efficiency coefficient (COP), which refers to the heat ratio of the input. Its cooling efficiency is shown by the energy efficiency ratio (EER), which is the ratio of heat absorbed (in Btu per hour) to the energy required to run the device (in watts).

Economics of Geothermal Heat Pumps

Although residential GHP systems cost more than other heating and cooling systems often for purchase and implementation, properly-sizing and designed GHPs provide more energy per unit used compared to conventional systems.

For more energy, household water can be heated by GHPs equipped with a device called the “super-heater.” The heat extracted from the house in the summer cooling period is used to help heat up the water. Water heating prices are decreased by approximately half during the winter.

You will recoup your initial investment in two to ten years through lower utility bills, depending on conditions like the climate, the system features you choose and the funding and benefits that are accessible.

Evaluating Your Site for a Geothermal Heat Pump

The ground is relatively steady in the USA, and geothermal heating pumps (GHPs) can be used nearly anywhere effectively. Nevertheless, your local network provider/installer will be able to determine the best type of floor loop for your location by using your unique geographical, hydrological and spatial resources.

Geology

While planning a ground zone, attention must be paid to considerations such as the properties of your soil and rock (which can influence heat transfer rates). For instance, soil that has good heat convection properties involves less piping than soil that has weak heat transfer properties to absorb a certain heat. The required amount of soil often contributes to the design of the system, System providers can install vertical ground loops instead of horizontal loops in areas with large hard rock or ground too shallow for trench.

Hydrology

The quality of soil or surface water often leads to deciding on the form of soil loop to be used. Surface water bodies can be used as a source of water for an open-loop network, depending on factors including depth, volume and water quality.

Before installing an open-loop device, be confident that your structure provider has thoroughly examined the hydrology of your location, this helps you to avoid possible issues such as exhaustion and pollution of the groundwater. Closed loop systems usually pose little or no environmental risk for antifreeze fluids.

Land Availability

The volume and size of your land the landscape and the position of subways or sprinkler systems all relate to the design of your system, for newly constructed buildings with enough ground, horizontal soil loops (usually the most economical) are normally used.

For existing buildings, vertical or more lightweight horizontal “Slinky” systems are frequently used since these minimize landscape perturbation.

Installing Geothermal Heat Pumps

The question is how to install a geothermal heating system? the installation process on your property for ground source heat pumps (GSHP), depends on the type of ground loop you build and on whether, among other things, you need a new conduit network.

Before installation: know your heating and cooling needs

Before you know how to install a geothermal heating system; a home contractor will be in your home to visit your property and determine your heating and cooling needs before adding ground source heat pumps. He will measure “J-manual,” which provides information on your property’s heating and cooling loads. Any State or local benefits must sometimes be eligible for a Manual J. It is also possible that your contractor collects any already existing tubes.

During your visit, home contractors will also discuss the current climate control program and your project objectives.

As example, do you only want to heat up a new system to your house, or do you want the new system to cover your property as much as possible? The form and scale of the geothermal system proposed will be influenced by the answers to these questions.

To properly install the tubing, professional technological skills and equipment are required, so the installation of the GHP device isn’t an easy task. Certified and professional installers should be essential.

A closed or open loop system consists of the ground heat controller in a GHP device. The most famous is a closed loop, where a long polyethylene pipe is horizontally buried at a depth of 4 to 6 feet or vertically at a depth of about 100 and 400 feet. These pipes are filled with a water-freeze solution which works as an exchange of heat and energy efficiency. In winter, heat is extracted from the soil and brought into the building by the fluid in pipes. During summer the device switches around and absorbs heat to the colder surface from the house.

4 steps to install Geothermal Heat Pump system

A ground source heat pump installation is completed by four important steps:

  • Ground loop installation
  • Ductwork installation
  • Heat pump installation
  • Wiring and final connection

The first three measures will not be done in the order given, the physically separate elements include the foundation coil, ductwork and heat pump. Therefore, ductwork must not be built except where your property does not have one or if significant maintenance is required to your current ducts.

1. Ground loop installation

Installing the ground loop is the first step in a geothermal heat pump system. Your contractor will require heavy machinery to dig the trench onto your grounds and will then install the actual tube in the ground. The contractor needs to dig trenches roughly 6 feet deep and 3 ft wide for horizontal field loops. The installer may need a few hundred feet deep into the Earth for a vertical ground loop.

2. Ductwork installation (if necessary)

Your geothermal contractor installs the required indoor ductwork after digging the trenches and installing the earth loop equipment. This step is optional: you can use the system to hold heated or cooled air if you have enough pre-existing ducts.

3. Heat pump installation

The heat pump machine itself will be mounted later. You have to uninstall certain parts first if you install an internal furnace and central air-conditioning unit. The new heating pump is installed and attached to the system of your duct.

4. Wiring and final connections

Finally, you must attach the heat pump to the ground circle so that the heat flows and the home power device can ensure the ventilator has the energy to run and blow in the whole house.

Maintenance of Geothermal Heat system

After knowing how to install a geothermal heating system, now you have to know how to maintain this system to avoid geothermal heating problems. This system is important to maintain the unexpected failure is reduced through a controlled program. The filter must be tested and adjusted as required, as the filters and fan their output.

Because of its safe, energy-efficient and cost-effective environmental conditions, its use is therefore of great benefit to everyone.
