Technological advances provide new ways of save energy, and this is where understanding how the aerothermal energy and what advantages it will provide us in an installation that we practice at home, be it for air conditioning, heating or ACC (Air Conditioning) and what electrical savings will bring us.
The development of air-thermal pumps is making it possible for them to be an alternative to systems conventional installed at home. Faced with these, the process installation and commissioning is simpler, safer and the maintenance requirements are very low.
The aerothermal concept is based on a technology that extracts energy contained in the air exterior thanks to a system of pumps. The teams can extract up to 75% of energy from the air we find in the atmosphere and thus, we reduce the use of electricity to the team, using only 25%.
These aerothermal equipments function as a standard and traditional heat pump but offers three different possibilities in the same installation; we will have heating in winter and cooling in summer, like hot water all year round .

We must be clear that it is a technology that uses how to base the energy of the air to
First, we have to understand that there are two systems main ones, the monobloc and the bibloc:
In the following video we will better understand how to obtains aerothermal energy and why it helps us to save (At the end there is a video of a technician explaining it more detail):
To clarify concepts, the process for getting energy would be:
In the end, in our house we would have a scheme like:
The following schematic reflects two common teams. He first, Outdoor Unit + Indoor Unit that incorporates DHW, and the second, Outdoor Unit + Indoor Unit where the DHW deposit is individual:
By incorporating these teams into our facilities we obtain savings important energetic when reaching a key point of the energy efficiency. The process that occurs in aerothermal energy can be broken down into 4 phases from a technical perspective:
This use of energy is done through air source heat pumps , mainly for heating systems and for water production domestic hot at high temperature.
If we want to learn from a technical perspective how to produces heat (Video from HERE) and how cold is produced (Video from HERE).
The systems are initially designed to be used in what are town houses, single-family homes or small and medium-sized buildings , the main stumbling block is all the installation that it carries behind with its unit or units exterior.
Manufacturers have come a long way in the different capacities provided by the facilities according to the equipment we use. Whether for new construction, reform or rehabilitation, heat pumps offer multiple possibilities in the combination of their teams. As examples:
As for the same surface area to be heated, the installation of a air-thermal heating costs a little more than conventional heating, but it pays for itself very quickly, a few 5 – 6 years.
The only element that has wear in the fuel pump heat, it is the compressor, which has a very long useful life and which it is easy to replace by technical service correspondent. The air-sourced heat pumps They have an average lifespan of around 20-25 years .
The aerothermal heat installations do not depend of a fuel storage that must be renewed periodically or of specific connections, and the location of machines is not conditioned by chimneys or production of combustion gases.
In addition, current facilities provide zone temperature control to improve energy savings energy:
A modern heating installation with air pumps aerothermal heat systems , allows us to combine low-temperature heating with the simultaneous production of DHW in proper hygienic conditions and, with a good design installation, with the same system perform the refrigeration in summer without losing the rest of the capacities.
Depending on the outside temperature, the energy required is a consumption of between 25 and 50% of the heating power propagated. That is to say, that at least half of the energy will be free.
Some users are asking us what There is a difference between aerothermal energy or geothermal energy and its consumption in homes. Although we are comparing two technologies to produce renewable energy, have technical aspects of different facilities and, above all, where they get the energy that we will use at home.
These two ways of obtaining renewable energy have their advantages and disadvantages, and compare aerothermal energy with geothermal energy depends on many factors as explained by the company specialized in geothermal Geothermal Vertical; the construction characteristics of the dwelling (including plot area), of the energy consumption that we need for home and the location due to its weather conditions You have to ask the experts and compare!
Broadly speaking, although both technologies have similar yields, we could say that; although that a geothermal installation is higher in price, we will always obtain a constant temperature and, the aerothermal installation can be more cheap, but we depend on weather conditions (air temperature) where we will not always get a constant temperature.
One of the most serious studies that exists is a thesis doctoral program on economic, energy and environmental analysis of the use of aerothermal energy (Can be consulted from HERE). Evidently, manufacturers only offer benefits, but if we review the thesis we will see that the savings are important, especially if we use underfloor heating or efficient radiators.
Leaving aside the technical explanation of the COP, and what is the performance coefficient. Said coefficient will vary in depending on the outside temperatures of the house, as well as depending on the setpoint temperature chosen by the user of the house and the flow temperature of the water that requires each heating system for the transmission of heat in the home (underfloor heating, fan coils or radiators) .
For every kWh of energy we consume, for any of existing traditional systems such as electric boilers, of gas or diesel, provide us with a calorific power different. Each team has its own performance, although very similar to each other except for aerothermal energy, which is much more efficient as we see in the previous image.
After learning about the problems of the aerothermal energy and the advantages... Would you decide on a air source heat pump?
A realistic explanation from a technician who does the right things things and recognized on YouTube is the following video (recommended to look at the end with the conclusions):
Aerothermal heating: when installing a radiant floor or low consumption radiators without the need for a boiler confirms significant energy and electricity savings.
Today, as large retailers and brands of aerothermal energy equipment we have Toshiba , Daikin , Mitsubishi , Vaillant , etc., who can further provide facilities that cover everything in one: heating, cooling and even ACS (Hot Water sanitary)
It is an important investment, and, therefore, it is necessary to look for in quality and brand with good guarantees that translates into prices that are not so low but with durability in the installation.
As always! Request different budgets before buy an aerothermal pump , both in stores neighborhood (sometimes surprising in prices) as in large surfaces in the style of Leroy Merlin, Bricodepot, Bauhaus… specialized and with serious advice.
The price of aerothermal energy varies according to size of the house, of the equipment that supplies us with cold or heat as well as the brand. The range of pumps The most economical aerothermal system is around 2,000 Euros for heating and ACS . Compare!! And remember to treat the installation issue, if it is included in the price or not.
