Our History

Founding of Diathermiki in Thessaloniki

1999 was the year Diathermiki was born, based in the heart of Thessaloniki. The company started its journey in the energy sector with the determination and vision of the first seven founding members. These pioneers laid the foundations for creating a dynamic and innovative network that would serve the needs of professionals and consumers across Greece.

Acquisition of Property in the Center of Thessaloniki

In 2005, Diathermiki took a significant step towards establishing its presence in the market by purchasing owned offices in the center of Thessaloniki. This strategic move strengthened our corporate identity and our ability to provide even better service to our ever-growing clientele. The new offices became the coordination center for our expansion and growth.

Expansion into Renewable Energy Sources

In 2009, Diathermiki introduced photovoltaic products into its network, responding to the new market needs for renewable energy sources. Our entry into the photovoltaic sector was a milestone for the company, offering our partners the ability to integrate innovative energy solutions into their products and services. This step was crucial for strengthening our network and expanding our offerings to consumers.

Our Network Reaches 100 Members

After more than a decade of steady growth and close collaboration with our partners through annual conferences and daily communication, Diathermiki reached the significant milestone of 100 member stores. This achievement highlights our reliability, long-term commitment, and our ability to offer innovative and trusted solutions in the energy sector.

Establishment of the Electronic Platform b2benergymarkt.gr

2021 marked Diathermiki's entry into the digital age with the establishment of our electronic platform, b2benergymarkt.gr. This platform was designed to offer convenience in our partners' purchases and to facilitate the management of their energy product needs. This digital transition strengthens our commitment to staying at the forefront of technological advancements and providing swift and efficient solutions to our network.

Diathermiki's Network Reaches 300+ Members

In 2024, Diathermiki's network has evolved into the largest energy network in Greece, with over 300 members. Serving the needs of all consumers, from Evros to Crete, is our primary priority, and our continuous expansion reflects the trust and dedication of our partners. With a strong network and a commitment to excellence, we continue to grow and innovate in the energy sector.
