As you already know, aerothermal energy is a system capable of extracting the energy contained in the outside air of a higher-performance property. It has great energy efficiency because it is capable of converting one kilowatt of energy consumed from the network into 4 kW of thermal energy for the air conditioning of the home.
This means that, while its owner pays only 25% of the energy that the aerothermal system produces, he enjoys an efficiency and performance of 400%.
Below we give you the reasons why, if you are thinking of carrying out this installation in your home, you should think about combining aerothermal energy with solar panels.
An installation of solar panels, by itself, allows you to reduce the electricity cost of a property by up to 70%, as it converts solar radiation, which is free and inexhaustible, into the electrical energy that needs a supply for self-consumption.
However, air conditioning consumption in the coldest and hottest months of the year accounts for more than 80% of the electricity bill, and combining solar panels with an aerothermal system allows this expense to be covered with wind energy.
This completely limits costs, and can even eliminate them completely in a renewable way.
We have already mentioned in the previous section that solar panels are capable of converting electrical radiation to supply the consumption needs of a property. It achieves this thanks to a solar inverter, the photovoltaic panels themselves and a series of connectors that allow their operation. It does not require any type of special maintenance and its useful life can often exceed 25 years.
Now, how does aerothermal energy work? This system operates thanks to a heat pump that obtains the energy contained in the outside air and transmits it to the interior of the room in the form of cold in summer, heat in winter and domestic hot water throughout the year.
In this case, its owner will have to choose the thermal emitter intended to transmit heat to the rooms: underfloor heating, low temperature radiators, francolis and/or air conditioning.
The price of installing aerothermal can range between €7,000 and €24,000 when the device provides heating and domestic hot water. While, if it is an air heater for DHW, its price is around €1,900 and €3,000.
In this case, the most important factor that influences the final cost is the size of the home, since the necessary power of the heat pump, the length of the hydraulic installation and, if underfloor heating is chosen, will depend on this. the necessary installation meters.
On the contrary, the cost of installing solar panels increases the larger the size of the house, hovering around €2.5 per kW installed. It will also depend on the light consumption needs of its inhabitants, the annual hours of sunshine in the province and the type of property: apartment, semi-detached or single-family home.
To give us an idea, implementing a solar energy system in Spain involves spending around €4,500 on a single-family home, including both the necessary photovoltaic devices and labor.
