What is an air source heat pump and how does a heat pump work?

The most efficient air-source heat pumps are the so-called air to water heat pumps, so called because they extract heat from the energy of outside air and transfer it to the water. By contrast, air conditioning units (air to air heat pumps) extract heat from the air and transfer it to the inside through the air and they are unable to heat domestic hot water (DHW) and heating. 

Thanks to the high performance of the different types of air-source heat pumps, we can multiply electricity consumption by 3, 4 and 5 (depending on the external conditions and the installation), i.e. with 1 kW of electricity consumed we can generate 3 kW to 5 kW of heat. Asturias is very suitable for heat pumps due to its average winter temperature. 

FAQ’s

1- Can the house be cooled in summer and heated in winter with air source energy in Asturias?

One of the great advantages of the heat pump is the ability to heat, cool and produce domestic hot water (DHW) with the same equipment. The air-source heat pump extracts heat from the air in winter to heat the installation and to produce DHW; in summer, the air-source heat pump transports the heat inside the house to the outside, thus reducing the temperature of the house.

2- What is the difference between air conditioning and air source in Asturias?

Air conditioning is a type of air-source heat pump of the air-air type, this means that it extracts energy from the air and transmits it to the interior of the installation by air, so air conditioning cannot be used in the form of heat with water-based systems, such as underfloor heating, radiators (nor in low-temperature radiators) and cannot heat DHW. In addition, air conditioning units are less efficient, more polluting due to the large amount of refrigerant they use, and more expensive to maintain.

The monobloc air-source heat pumps are of the air-water type, as they exchange heat with the outside air and transmits it to the inside by means of water. Monobloc refers to the fact that all the components of the air-source system are located in the outdoor unit. This system is an improvement in energy savings and thanks to the water circuit, the water is perfect for heating radiators.

3- What is the difference between geothermal and air source?

Both systems use the heat pump technology, the only difference is the medium from which the energy is obtained, in the case of air-source energy it is obtained from the air, whereas in geothermal energy it can be obtained from the earth or water. Heat pump 

4- What is a monobloc air source heat pump?

It is a type of air-source in which all the components of the heat pump are in the outdoor unit, making it a very compact and easy to install system. The indoor unit usually has different models, some more basic that consist only of the control screen and other more complex with hydraulic kits and even domestic hot water tanks.

The outdoor and indoor unit are connected solely and exclusively by water, in certain cases of more extreme external temperatures by glycol water to prevent freezing.

5- How does this system achieve large savings if it uses electricity?

Heat pumps use energy to run the compressor, a component of the heat pump; however, this electrical consumption is minimal compared to the energy that is extracted, from the air in the case of air-source energy and from the earth or water in the case of geothermal or ground-source heat pumps. The heat pump can generate from 1 kW of electricity consumed up to 5 kW of useful thermal energy for the air conditioning of the house. Thanks to these high efficiencies, large savings can be achieved. 

6- Can air source systems be used for air conditioning?

Yes, air-source systems can include air conditioning, taking advantage of the capacity of the air-source heat pump to cool the indoor air during the warmer months.

7-What are the advantages if an air source heat pump over other heating and cooling systems?

Air-source heat pumps are efficient, use renewable energy and can provide heating, cooling and DHW all in one system.

8- What should be considered when installing an air source system?

When installing an air-source system, it is important to consider the size of the house, the heating and cooling needs, and the proper installation of the air-source heat pump.

9-Can the installation of aerothermal and photovoltaic be combined?

Of course. It’s a great combination. The excess electricity is used by the heat pump. Dependency on the electrical grid greatly decreases and savings increase

10- What capacity should an air source heat pump have for a 60 m2 or 200 m2 house?

The capacity of the air-source heat pump should be chosen according to the size of the house and its specific needs. There are models suitable for different house sizes, from 60 m2 to 200 m2 or more.
