Diathermiki was founded in 1999 in Thessaloniki by a group of store members, professionals in the fields of Heating, Plumbing, Air Conditioning, Electrical, Photovoltaics, and Building Renovation.
The initial purpose of the company was to strengthen each store in its city and to establish strategic partnerships with leading suppliers in the industry. Through the company's upward trajectory over the years, we have evolved into the largest network of energy stores in Greece with the participation of 300+ stores.
Our goal is to collaborate with the most dynamic store in each region and to maximize the growth of our stores, so that our members become and remain the first centers of technical service and commercial distribution in their cities.
