High-performance heating/cooling systems are another step forward towards sustainable housing. Green construction reduces the environmental impact of construction processes, but what happens when the time comes for the inhabitants to move in? Heating and cooling our homes represent one of the most important everyday expenses and at the same time they are one of the main culprits of residential buildings’ CO2 emissions, which in Spain account for 30% of the total emissions.
When designing sustainable, eco-friendly homes it is essential to choose the heating/cooling source that is best suited to the conditions of the building and the climate of region in which it is built. It is thus possible to reap the benefits of the renewable energy sources available and release a lower volume of emissions into the atmosphere. There are many examples of renewable energy sources for housing, for example solar panels, biomass installations or aerothermal systems, which we are going to discuss below.
What is an aerothermal system?
Aerothermal systems are sustainable heating/cooling technology which uses the energy present in air to heat or cool spaces and produce domestic hot water. They operate by extracting the temperature from the air and transmitting it to the different rooms in the home efficiently and cleanly.
Aerothermal pumps installed in the dwellings are responsible for carrying out this heating/cooling function. The outdoor air is collected using a condenser and it is propelled through a circuit to the evaporator that is located inside. The coolants inside the circuit are responsible for modifying the temperature of the air collected from the outside and this process produces both heating in the winter and cooling in the summer. Furthermore, using this technology it is also possible to supply the dwellings with hot water.
Once the air temperature has been modified it can be distributed around the spaces using a variety of installations such as radiators, radiant underfloor heating, heat pumps or air conditioning splits, making aerothermal systems a highly versatile and functional option. And all using only electricity as the power source.
The advantages of aerothermal systems
Aerothermal installations extract up to 77% of the energy they use from the surrounding air. Aerothermal systems currently represent an interesting alternative to traditional heating systems, the primary cause of household electricity consumption and the installation of such systems is becoming increasingly more widespread. At AEDAS Homes, we have opted to employ aerothermal systems in a number of our developments; the following are the main advantages these systems offer:
– Clean and eco-friendly
One of the most significant features of aerothermal systems is that they work without combustion, therefore they do not release emissions into the atmosphere or generate any kind of waste. Alternatively, thanks to this means of operating, it is rated as a renewable energy source in the Technical Building Code, because its only source of power is environmental temperature.
– Efficiency and savings
The energy extracted from the environment is completely free, i.e. you only pay for the electricity needed to operate the pump. If, moreover, we bear in mind that the amount of electricity required to operate aerothermal systems is minimal. It is therefore one of the most efficient heating/cooling systems on the market.
Aerothermal systems operate without boilers so this means that homes are safer; they do not produce fumes or imply any risk of fire stemming from combustion. Furthermore, the installation is very simple and barely requires any maintenance, which ensures it functions correctly and you are worry-free.
Aerothermal systems in new-build housing. Do you save on your electricity bill?
As we have seen, aerothermal systems bring many benefits both for their users and for the environment. At AEDAS Homes, we are committed to incorporating efficient technology into our developments to create buildings with the minimum environmental impact possible. Hence, aerothermal systems form part of our projects, together with other renewable energy sources such as solar power.
