Aerothermal systems are becoming a more popular option for homeowners looking to heat and cool their homes efficiently.

These systems use the earth’s natural heat to provide heating, cooling, and hot water.

Aerothermal systems are also known as ground source heat pump (GSHP) systems. They are one of the most efficient ways to heat and cool your home as they use the earth’s natural heat to do so.

In this article, we will take a look at how Aerothermal systems work and the benefits they offer.

How Do Aerothermal Systems Work?

Aerothermal systems work by exchanging heat with the ground. The system uses a loop of pipe, called a ground loop, which is buried in the ground.

A heat pump exchanges heat between your home and the ground to provide heating and cooling.

The earth’s temperature underground is relatively constant, so it can be used to heat or cool your home all year round.

In the winter, the system takes heat from the ground and uses it to warm your home.

In the summer, the system takes heat from your home and transfers it to the ground.

This process is repeated over and over to provide a constant supply of heating or cooling to your home.

How Aerothermal Energy Works. Heat Pumps

To work, a heat pump requires the following components:

  • Compressor
  • Condensor
  • Expansion Valve
  • Evaporator

Compressor

It’s the job of the compressor to move refrigerant around the system. The compressor is located inside the outdoor unit and is powered by electricity.

Condenser

The condenser is also located in the outdoor unit. Its job is to release heat that has been collected from inside your home.

Expansion Valve

Its job is to transform electrical energy and raise the pressure of the refrigerant fluid. The expansion valve is located between the outdoor and indoor units.

Evaporator

The evaporator is located inside the air handler or furnace. Its job is to collect heat from the air and transfer it to the refrigerant fluid.

The Advantages And Disadvantages Of Aerothermics

The advantages of aerothermics systems:

  • Offers a high level of efficiency and performance.
  • Helps reduce emissions and energy consumption.
  • Produces fresh air in summer.
  • Heating in the winter.
  • Hot water throughout the year.
  • The coefficient of performance (COP) is low

Offers a high level of efficiency and performance

Aerothermics systems are extremely efficient, as they use the earth’s natural heat to provide heating, cooling, and hot water.

Helps reduce emissions and energy consumption

Aerothermics systems help to reduce emissions of greenhouse gases, as they rely on renewable energy sources.

Produces fresh air in summer

As well as providing cooling, aerothermics systems also help to circulate fresh air in your home.

Heating in the winter

Aerothermics systems can provide heating in the winter months, as they use the earth’s natural heat to do so.

Hot water throughout the year

Aerothermics systems can also provide hot water all year round.

The coefficient of performance (COP) is low

The coefficient of performance (COP) is a measure of the efficiency of a heat pump. The COP of an aerothermics system is lower than that of a traditional heating and cooling system.

The disadvantages of aerothermics systems

  • Need a sufficient amount of space
  • High initial cost of installation
  • Difficult to install
  • Not entirely carbon neutral

Need a sufficient amount of space

Aerothermics system need a fair amount of space to be installed, as they require a ground loop.

High initial cost of installation

The initial cost of installation can be high, as aerothermics systems are not commonly found in homes.

Difficult to install

Aerothermics systems can be difficult to install, as they need to be connected to the ground.

Not entirely carbon neutral

While aerothermics systems rely on renewable energy sources, they are not entirely carbon-neutral.

This is because of the emissions produced by the compressor and it also requires electricity to operate.

Systems That Work Well With Aerothermics Systems

ThermoDynamic Underfloor Heating

The thermodynamic system is used to heat water by absorbing solar radiation and heat energy from the environment.

This system works in cold climates, unlike solar collectors, because it operates when there is no direct sunlight (at night, during hazy and rainy weather, all year round).

How does ThermoDynamic Underfloor Heating work?

ThermoDynamic underfloor heating works by circulating hot water through a system of pipes. The pipes are laid underneath your flooring, and the heat from the water warms the floor above it.

Large Radiators

Aerothermics systems require large radiators to work effectively. This is because the heat pump needs a large surface area to transfer heat to the refrigerant fluid.

Large radiators are usually made of cast iron or steel, and they are often used in commercial applications.

Aerothermal Heating And Savings

Aerothermal technology exploits the heat energy in the air, an endless source of energy.

As a result, you will no longer need to use gas or fuel, making it a more environmentally friendly option as well.

Aerothermal systems may be used to both heat and chill space, and they can also provide clean hot water.

FAQs

Are Aerothermal systems more popular or less popular than air source heat pumps?

For residential properties, air-source heat pumps are far more popular than aerothermal systems. This is because they are easier to install and they have a higher coefficient of performance (COP).

How much does an Aerothermal system cost?

The cost of an aerothermal system will vary depending on the size and type of system you need. However, the initial cost of installation can be high, as these systems are not commonly found in homes.

Are Aerothermal systems noisy?

Aerothermal systems are not typically noisy, as the compressor is located outside the home. However, you may hear a faint humming noise from the ground loop pumps.

Why is the COP of an Aerothermal system lower than that of an air source heat pump?

The COP of an aerothermal system is lower than that of an air source heat pump because the compressor needs to work harder to circulate the refrigerant fluid through the system.

How do I know if an Aerothermal system is right for me?

If you are looking for environmentally-friendly heating and cooling option, then an aerothermal system may be right for you. These systems use renewable energy sources and they are very efficient. However, they can be difficult to install and the initial cost of installation can be high.

In Summary

Aerothermics systems offer a number of advantages, including high efficiency and performance, the ability to reduce emissions and energy consumption and to produce fresh air in summer.

They also provide heating in winter and hot water all year round. However, they have a lower coefficient of performance than traditional heating and cooling systems.

Additionally, they require a fair amount of space for installation and can be difficult to install. Aerothermics systems are not entirely carbon-neutral, as they produce emissions from the compressor.

However, they are more environmentally friendly than gas or fuel-based heating systems.
