What is aerothermal energy and how does it work?

Aerothermal energy is an innovative air conditioning technology that harnesses the thermal energy contained in the ambient air to provide heating, cooling and domestic hot water production systems through a single installation unit. 

Thanks to its high efficiency and respect for the environment, aerothermal energy has become one of the most sought-after solutions for heating and cooling homes in our country.

The system works through a heat pump that operates by means of a thermodynamic cycle between the refrigerant gas in the equipment and the outside air absorbed by the fan. These are the steps in the operation of aerothermal energy:

1. Air collection: uses a heat pump ( outdoor unit ) to extract heat from the air. 

2. Cooling: The heat pump contains a refrigerant that circulates between the outdoor and indoor unit. In the air collection process, the refrigerant absorbs heat from the air and evaporates, becoming a low-pressure gas.

3. Compression: The compressor increases the pressure of the refrigerant gas and raises its temperature. The gas is then fed to the heating system or domestic hot water via a heat exchanger. 

4.Distribution: The thermal energy is distributed via a central heating system, underfloor heating or radiators, providing heat to the home.

Reverse mode: For summer use, the cycle is reversed and the heat pump extracts heat from the home and channels it outside to provide cooling.

What are the advantages of installing aerothermal energy?

The installation of an aerothermal system offers a number of important benefits in terms of energy efficiency and comfort in the heating and cooling of a building. These are some of the main advantages:

Energy efficiency:

The aerothermal system is highly efficient compared to conventional heating and cooling systems. By using air as a renewable energy source, it can provide more thermal energy output than it consumes in electrical energy to operate, reaching an efficiency of over 500%.


It can provide both heating and cooling, making it suitable for year-round use and eliminating the need for separate systems, providing comprehensive solutions for space air conditioning and hot water production.

Sustainable energy:

Aerothermal energy does not use any type of fuel, so it is considered clean energy. By reducing dependence on fossil fuels and using renewable energy sources such as electricity, aerothermal energy helps to reduce the carbon footprint, greenhouse gas emissions and air pollution.

Economic savings:

Although the initial investment may be higher than traditional heating and cooling systems, over time, the aerothermal system will be more economical due to its energy efficiency and lower operating costs.

Subsidies and grants:

In the vast majority of local governments, tax incentives and subsidies are offered for the installation of aerothermal systems with the aim of promoting energy efficiency and the transition to cleaner energy sources.

Quick payback:

The payback of an aerothermal system is typically between 4 and 5 years. This fast payback is achieved thanks to the high energy efficiency and significant savings in heating and cooling costs, as aerothermal systems significantly reduce energy consumption, which also leads to lower electricity bills.

What is the price of an aerothermal installation?

The price of an aerothermal installation depends on several factors and can vary considerably depending on the specific needs of your home. However, the approximate cost is usually between 8,000 and 25,000 euros. 

In order to have a reference of the initial investment required for an aerothermal system, one of the most influential factors in relation to the price of the installation is the size of the house where you want to install the system. 

The size of the house determines the power required by the heat pump, the length of the installation, the number of metres of underfloor heating (if this is the option chosen) and the labour required to carry out the installation.

Even so, if you are considering installing aerothermal energy at home, it is necessary to carry out a personalised study to evaluate your specific situation and the specific needs of your home. Sunhero’s team of experts will analyse your consumption patterns and the characteristics of your home in detail in order to offer you a solution that adapts to your needs.

Requirements to enjoy an aerothermia installation

Are you thinking of installing an aerothermal system in your home? We recommend that you consider some requirements to ensure that you carry out this process in an effective way. 

Thermal insulation: In order to maximise the efficiency and performance of the aerothermal system, it is advisable to have good thermal insulation in the home. This insulation consists of implementing measures that prevent heat loss or heat gain in order to optimise the operation of the aerothermal system.

Study of the project: A preliminary study is essential in order to determine factors that will have a direct impact on the success of the installation. With a complete analysis, you can evaluate the energy needs of your home, considering the demand for heating, cooling and domestic hot water production. Taking these factors into account, you can correctly size the best system for you.

Available space:Before installing an aerothermal system at home, it is important to determine the space available for the installation of the main components and the outdoor unit. In this assessment, it is essential to consider the accessibility of the site to ensure that the equipment layout complies with relevant regulations. .

Permits and requirements: It is important to check the regulatory requirements and obtain the necessary permits to be able to install fan heat in your home. In addition, if you live in a block of flats, it is necessary to request permission from the residents’ association to install the outdoor unit on the balcony, in the window or on the roof.

Types of thermal emitters that you can use with aerothermics

If you are considering installing an aerothermal system at home, it is essential to consider the thermal emitters that are best suited to your home. Aerothermal energy offers different options for heat distribution and the choice of the most suitable thermal emitter for you is a key point that can influence the efficiency of your system.

Underfloor heating:

Underfloor heating is a heating system that is installed under the floor of a house or building. It uses pipes or electric cables to distribute heat evenly across the floor surface, allowing the space to be heated efficiently and comfortably. 

One of the main advantages of having underfloor heating in the home is the thermal comfort it provides, as there are no hot and cold spots. In addition, due to the even distribution of heat, underfloor heating can operate at lower temperatures than conventional radiator systems, which reduces energy consumption and heating costs.

Fan convectors:

A fancoil is a versatile device used in air conditioning systems to heat or cool indoor spaces. It works by using hot or cold water as a source of heat or cooling. 

Unlike other systems such as split systems, fan coils require water as a refrigerant. For this reason, this device is a highly demanded emitter in aerothermal installations. 

Low temperature radiators:

Low-temperature radiators are heating devices used in air-conditioning systems that operate at lower temperatures compared to conventional radiators. The lower the working temperature of the water, the higher the energy efficiency of the system and the higher its performance. 

In addition, low-temperature radiators are designed to operate with more energy-efficient heating systems, such as heat pumps. Due to their specific design and their ability to operate at lower temperatures, they are an attractive choice in modern, sustainable heating systems.

Conventional radiators:

Conventional radiators are heating devices used in air-conditioning systems that operate at higher temperatures compared to low-temperature radiators. 

These radiators are designed to operate with conventional heating systems using gas, oil and other heat sources that generate hot water at higher temperatures.
