Insulation and aerothermal energy, the perfect tandem

2021 has begun with the most expensive electricity prices in recent years, and with oil prices also reaching historic highs. This has led many people to pay exorbitant energy bills for heating.

It’s important to keep in mind that, to minimize heating consumption, the most important thing is to improve insulation. This can be inexpensive if we choose systems like plastic roof tiles, which don’t require extensive construction.

Once we’ve improved our insulation, there are several ways to reduce heating costs. The best option is to install solar energy systems. However, there are more economical renewable energy systems that reduce energy consumption for air conditioning by 70% and also allow for the production of hot water for domestic use. These are known as aerothermal heat pumps.

Aerothermal energy and energy insulation

Aerothermal energy involves absorbing the thermal energy contained in the air through a heat pump and converting it into heat or cold as needed. Depending on the user’s preferred system, the heat or cold generated is used to heat the building’s interior with air or water.

The aerothermal system basically consists of two parts: a unit located outside the building absorbs thermal energy from the outside air, and a unit located inside the installation room exchanges and distributes this energy throughout the building. The room can be heated using underfloor cooling or heating, or through air conditioning, radiators, fan coils, or even hybrid systems.

These are the advantages of installing an aerothermal system in your home:

• No combustion occurs, making it a safer system.
• Installation is simple and requires little space.
• The energy efficiency of an aerothermal system is very high
• It allows for various air conditioning systems: with aerothermal heating you can air condition with fan coils, with underfloor heating for heating and cooling, with radiators, or with mixed systems.
• A single system provides air conditioning and hot water production for the entire building.
• These types of systems consume 70% less than conventional systems.
• Proper installation avoids the requirement of the CTE (Center for the Protection of Domestic Hot Water) to install solar panels.

For all these reasons, aerothermal systems have become a kind of air conditioning system, providing hot water for buildings. Initially, they may require a larger investment than other systems, but they will quickly pay for themselves.

In this sense, if we install an aerothermal system and improve our home’s insulation with more economical systems like plastic roof tiles, we can reduce our air conditioning energy bill by more than 80%. Furthermore, if we manage to reduce our energy consumption, we will also reduce household pollution, something very important given the ravages that climate change is having on our planet.
