In Spain, the electricity bill has skyrocketed in the last decade. And while supply prices have risen, the need to invest in clean energy has become more evident in Europe. It is no longer enough to have air-conditioned houses, it is about betting on sustainability and achieving home comfort that is respectful of the environment. For this reason, there are modern and sustainable energy solutions such as geothermal and aerothermal energy . The Passivhaus standard and passive houses are an example of this good commitment to clean energy. Since, in that case, energy reuse systems are used. Precisely, the only mechanical system that is installed in passive houses is aerothermal energy . One of the two green solutions to achieve energy and comfort in an ecological way that we discuss today. Aerothermal energy is a technological system that reuses energy from the air and is capable of heating water or a room using cold air from outside. It also prod.
Uces the opposite effect in summer. Most of the energy it generates is completely clean, and the rest comes from electricity. Geothermal energy , on the other hand, extracts energy that is stored in the form of heat a few meters from the earth's surface, where the temperature is usually constant, Chinese Overseas Africa Number Data whether summer or winter. To do this, it uses a heat pump. Both systems are energetically sustainable and clear examples of where the sector has to go. Which of the two is better in each situation? Aerothermal; ecological and economical ventilation Aerothermia Aerothermal energy extracts energy from the street air efficiently thanks to a heat pump. It is a way to reuse outside air, regardless of whether it is very cold, to heat the room or the water. The aerothermal system extracts the energy contained in the outside air to convert it into heat inside the home, which is technically known as the refrigeration method . The system even works when outside temperatures are .
Below zero. With aerothermal energy , according to manufacturers, it is possible to achieve up to 78% completely free and recycled energy. The rest will be for electricity consumption, it will never come from fossil fuels. On the other hand, the pump that is used for the mechanical ventilation system is also renewable. Without a doubt, it is one of the most prepared methods for energy efficiency . Geothermal; earth energy Carbon monoxide gas Geothermal energy is also a totally renewable and ecological energy. In this case, it comes from the subsoil, which is undoubtedly an immense energy source, since the sun's energy is stored just a few meters above the ground. The earth's core can reach temperatures of 6,500 degrees, and geothermal heat pumps can provide heating, hot water and also air conditioning in summer. It is undoubtedly an ecological alternative different from aerothermal ventilation . Which of the two can work better in each situation? Which system best suits each person's needs? It will depend on many factors, such as the location where the house is located and the type of ho.
