000 Greek households benefit from assistance for environmentally friendly heating

Faced with the growing challenges of climate change and the increasing need to adopt sustainable solutions, Greece is now engaging over 100,000 households in a major energy transition. Starting in early 2025, an ambitious program supported by the European Union aims to modernize domestic heating systems by promoting the installation of green and renewable energy technologies. This initiative, structured around significant financial aid, constitutes a key step towards reducing dependence on fossil fuels and significantly improving the energy efficiency of homes. Let’s explore how this concrete support works on the ground to promote accessible and effective ecological heating for Greek households.

An enhanced budget for accessible ecological heating for over 100,000 Greek households

The Greek Ministry of the Environment and Energy published in November 2025 the first list of households benefiting from a national energy renovation aid program. More than 100,000 Greek households have been selected, demonstrating the project’s scope. Among them, about 5,000 are considered vulnerable, with no income conditions, and can receive up to 6,000 euros for the complete renovation of their heating system.

Initially, this program had a budget of 223 million euros, primarily financed by the NextGenerationEU fund. But in response to strong demand and the strategic importance of the scheme, the budget has been increased to 647 million euros. These resources, aligned with the RePowerEU policy and the national recovery and resilience plan “Greece 2.0,” strengthen the momentum of the energy transition in the country.

The initiative aims to replace old oil or natural gas boilers, which still equip the majority of homes, with renewable energy installations, such as heat pumps or thermal solar water heaters. These devices enjoy great attractiveness in Greece, particularly due to the abundant sunshine which favours thermal conversion even during the winter season.

• 50% to 60% of the cost is covered for households based on their income
• Vulnerable households have a ceiling for aid that can go up to 6,000 euros
• National goal: achieve 52.6% renewable energy in heating by 2030.
• In 2023, the renewable heating rate stood at only 26.2%, highlighting significant room for improvement.

These aids help limit the initial investment of households while contributing to a durable energy economy. For more details on possible savings and devices, find information on ecological heating and financial aids.

Vulnerable households	Up to 6,000 €	No conditions	Heat pumps, biomass heating, thermal solar

The key technologies of ecological heating recognized and favored by financial aids

Among the most promoted equipment in this program, heat pumps occupy a central place. They work by exploiting the calories present in the air or soil to produce heat, thus reducing fossil energy consumption. This technology has several advantages: it is efficient, economical, and environmentally friendly. However, installing it may require a prior technical assessment to check insulation and housing adaptation.

At the same time, thermal solar water heaters fully benefit from the exceptional sunshine in Greece, providing a free renewable energy source for producing hot sanitary water, even during the winter period. This solution is particularly suited to domestic needs and allows for a significant decrease in energy bills over the long term.

Biomass boilers, which use organic fuel, also represent an interesting ecological option, especially for rural areas where wood is locally available, thus promoting increased sustainability while supporting the local economy. To better understand these systems and their benefits, many detailed technical guides are available, especially on ecological biomass boilers.

• Heat pump: high efficiency and low electrical consumption
• Thermal solar water heater: free and renewable energy
• Biomass boiler: sustainable renewable fuel
• Hybrid systems: combine several technologies to optimize performance

These advancements accompany the fight against rising energy costs while participating in reducing the environmental impact related to domestic heating, a major issue in the Greek context. Paul Leclerc always recommends consulting a qualified plumber to ensure compliance and quality of installation, a guarantee of safety and lasting efficiency.
