A transition period for home heating in Spain
In 2025, Spain will launch a large-scale program to replace traditional gas boilers. For decades, such devices have provided warmth in most residential spaces, but now their use is gradually being phased out. The reason for this shift is new energy efficiency requirements and a push to reduce carbon dioxide emissions. European directives and national initiatives aim to encourage the adoption of modern and eco-friendly heating technologies.
Impact on the environment and energy consumption
Experts estimate that gas boilers are responsible for about one-tenth of global CO2 emissions. In Spain, around 42% of apartments and houses are heated with natural gas, another 14% rely on petroleum products, and 3% use coal. The residential sector as a whole consumes nearly half of the country’s total energy and accounts for more than a third of greenhouse gas emissions. Authorities expect that phasing out old systems will reduce energy consumption by 11.7% by 2030. Each EU country is required to achieve cumulative annual energy savings.
Modern alternatives and their cost
Instead of traditional boilers, the market now offers solutions based on aerothermal and geothermal technologies, as well as systems utilizing biomass, solar power, and hybrid complexes. Some options include installing individual heat pumps or condensing boilers, giving residents more independence. The cost of switching to new technologies ranges from €8,500 to €90,000, depending on the chosen system and the scope of work. The payback period depends on equipment efficiency and consumption levels, averaging between 7 and 10 years. Aerothermal systems can reduce heating expenses several times compared to gas alternatives.
Benefits for homeowners and government support
Switching to modern systems not only lowers utility bills and increases comfort, but also boosts property value. Experts estimate that energy-efficient homes can appreciate by up to 12%. In addition, homeowners can take advantage of government subsidies and special loan programs that simplify financing for such projects. Major banks, such as Deutsche Bank, offer solutions tailored for apartment buildings and single-family homes.
