Aerothermal energy has moved beyond being a technical term to become one of the most highly regarded heating and cooling systems in the residential sector.<\/p>\n
More and more people are taking an interest in this technology because of its efficiency, sustainability and energy savings.<\/p>\n
It is now considered a modern and reliable alternative to traditional systems such as natural gas or electric radiators.<\/p>\n
Many new-build developments now include it as standard, such as the flats by Marina d'Or Construcciones<\/strong>, which incorporate aerothermal systems as part of their commitment to energy efficiency.<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/marinadorconstrucciones.com\/wp-content\/uploads\/2025\/08\/aerotermia-marina-dor.webp” alt=”What is geothermal energy?

It is an electric, clean and safe system, compatible with underfloor heating, fan coils or low-temperature radiators.<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” text_text_color=”#000000″ text_font_size=”14px” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n Air-source heat pumps offer numerous benefits, which have boosted their popularity in both new and renovated homes:<\/p>\n 1.

The benefits of geothermal heating: savings, comfort and sustainability<\/h2>\n
<\/strong>The system\u2019s efficiency significantly reduces electricity consumption compared to conventional solutions. In many cases, a <\/span>reduction of 30% to 60%<\/strong> in heating and cooling costs is achieved.<\/span><\/p>\n
comfort <\/strong>The indoor temperature remains constant and comfortable all year round, without the sudden changes or dry air typical of other systems.<\/span><\/p>\n
<\/strong>As it does not use fossil fuels, aerothermal energy helps to <\/span>reduce the carbon footprint <\/strong>and improve air quality.<\/span><\/p>\n
<\/strong>systems operate at very low noise levels and require minimal maintenance.<\/span><\/p>\n
<\/strong>Homes with aerothermal systems tend to be valued higher on the market due to their <\/span>energy efficiency<\/strong>, a feature that is increasingly in demand.<\/span><\/p>\nAir-source heat pumps vs other HVAC systems: a technical comparison<\/h2>\n

aerothermal systems are capable of operating efficiently even at temperatures as low as -20\u00b0C, thanks to improvements in compressors and refrigerants.\n<\/li>\n
The systems are designed to deliver high thermal performance, especially when combined with suitable heat emitters such as underfloor heating or fan coils.\n<\/li>\n
In new-build homes such as those by Marina d'Or Construcciones, aerothermal systems are fitted as standard, avoiding additional costs and allowing you to benefit from them from day one.\n<\/li>\n
The indoor units are compact and the outdoor unit is no larger than a standard air conditioning unit.<\/li>\n<\/ul>\nHow much can you save with geothermal heating?<\/h2>\n
