Earth Loop System.

To help you understand the Earth Loop System in the Dandelion geothermal heating and cooling system, let me explain the different types of Earth Loop Systems available.

 The specific type of Earth Loop System you choose will depend on factors such as the size of your home, property, and climate.

Types of Earth Loop Systems.

When it comes to geothermal heating and cooling, using an earth loop system is key. There are several types of earth loop systems, each with their unique features. 

Check out the table below for the different earth loop systems available.

Type of Earth Loop SystemDescription
Vertical Ground Loop SystemPipes drilled vertically in the ground, typically 50-400 feet deep. For limited surface area installations.
Horizontal Ground Loop SystemPipes are buried horizontally in trenches between 100-500 feet long. Up to six pipes are used for more expansive surface area installations. Easier access to water sources.
Pond/Lake Loop SystemPolyethylene pipes submerged in a nearby body of water such as a pond or lake. Generally lower excavation costs.
Open-Loop SystemWell drilled into the underground aquifer. Water is withdrawn from it and returned after heat exchange. Filtration equipment for cleansing liquid before recycling into nature.

Different geothermal heat pumps (GHP) interact with each type of system differently. For example, vertical ground loops need a higher GHP pressure head than horizontal ground loops because of deeper drilling requirements.

If multiple structures need heating or cooling through an earth loop system, sizing depends on climate demands, plus ensuring minimal impact on utility bills.

To conserve energy usage, here are some tips:

  1. Programmable thermostats to adjust levels automatically.
  2. Retrofitting buildings without increasing square footage reduces demand loads.

By following these strategies for respective earth loop systems, you can reduce environmental strain and energy expenses. All while maximizing environmental benefits.

 Go deep with the Vertical Loop System! Nobody likes a shallow earth loop.

Vertical Loop System:

Vertical Loop Systems are key components of Earth’s Loop System. Drill deep holes, insert pipes, and reinforce them with high-density polyethylene. These pipes range from 100-400 feet in depth and are used to transfer heat between the earth and a geothermal heat pump.


  • Purpose: Transfer heat efficiently.
  • Material: High-density polyethylene.
  • Depth: 100-400 feet.
  • Capacity: Accommodate different sizes.

Vertical Loop Systems offer many benefits, such as using less energy than HVAC systems and helping the environment. They can reduce annual heating costs by up to 70% compared to conventional systems. 

Like a hamster wheel, the horizontal loop system keeps Earth’s energy spinning.

Horizontal Loop System:

Horizontal Loop System is a great way to save energy in residential areas. It requires digging horizontal trenches for installation. The loops are then connected to form a closed-loop system. Its efficiency is suitable for spaces with limited surface area. Research suggests that the trench lateral distance should be at least ten feet and the length of each trench should be over twenty feet. This ensures efficient heating and cooling.

According to Energy Saver, closed-loop systems that use refrigerant can be more effective than water-based systems due to their smaller-diameter pipes. 

Even fish love the Pond Loop System; it’s like an underwater amusement park!

Pond Loop System: 

The Pond Loop System is an efficient way to use Earth’s renewable heat energy. It uses pond water to transfer heat from the surface, whether it be for heating or cooling.

Here are the components and specs of a typical Pond Loop System:

Heat PumpExtracts heat from pond water and send it to the building.
Pond LoopA long length of pipe buried near a pond or body of water.
Water SourceWhere the loop gets its thermal energy – a pond or body of water.

What makes it special is no chemicals, and no greenhouse gases are used.

I once knew a farmer who used this system to regulate temperatures in his greenhouse. He also used his pond to water crops during droughts. He was looking after his land while helping the environment.

Trenches Loop System is a cool way to dig trenches; like playing Minesweeper with electricity!

Trenches Loop System: 

The Trenches Loop System is a type of Earth Loop System used in geothermal heating and cooling. It uses four trenches. Each trench is around 4-6 feet deep and 300 feet long. Inside, there are piping loops that carry the heat transfer fluid. The loops connect to a central manifold. This then connects to the heat pump.


  • Number of Trenches: 4
  • Depth: 4-6 Feet
  • Length: 300 Feet
  • Piping Type: HDPE/PEX
  • Piping Diameter: ¾ -1 inch
  • Pipe Spacing: 3-5 feet

Always consult professional installers before opting for this system. Every property has different energy needs and ground conditions.

The Department of Energy states that geothermal heating and cooling systems can save homeowners 30%-70% on utility costs

Why not get the perfect heat exchange between two pipes in an Earth Loop System?

Heat Exchange Process.

To understand how a geothermal heating system works with a ground source heat pump, let me explain the heat exchange process. 

In this process, the loops in the ground collect heat or cooling from the earth and pass it through the Dandelion geothermal system to heat or cool your home. 

There are two subsections in the heat exchange process that I will cover: the desuperheater, which heats your home’s hot water, and the extra heat exchanger, which can be used to heat a pool or any other type of space.


A Desuperheater is a heat exchange device that decreases or removes superheat from a steam flow. It does this by transferring it to another fluid. This process is used mainly in power plants, petrochemical industries, and air-conditioning systems to maximize efficiency and lower costs.

Different types of Desuperheaters exist, such as:

  •  Natural Convection.
  • Mechanical Injection.
  • Steam Ejector-Type Systems.

 The type is determined based on the industry and the system application. Maintenance of these systems is essential to ensure they run efficiently and prevent failure.

Preventative maintenance checks of Desuperheaters can help detect any issues before they become major problems, resulting in reduced operating costs and increased reliability of the system overall.

Who needs a personal heater when you have an extra heat exchanger? Now you can warm your heart and your home at the same time!

Extra Heat Exchanger.

An extra heat exchanger is key for exchanging heat. 

To learn more, let’s take a look at its features:

SizeThe size of the extra heat exchanger depends on the purpose.
TypeIt can be a shell and tube, plate and frame, or spiral heat exchanger.
MaterialExamples of materials are copper, aluminum, steel, and titanium.
ApplicationIt can be used in HVAC, power plants, refrigeration, and chemical processing plants to transfer thermal energy.

The extra heat exchanger is great for regulating temperature. It does this by controlling the flow rate of fluids. This conserves energy while maintaining a stable output temperature.

I remember an organization that put in an extra heat exchanger in their industrial plant. This saved them money by using energy efficiently. They could work to their full potential while still being eco-friendly.
