Summary
A big pilot solar thermal installation was constructed and brought into operation in April 2002 in the elderly people home "St. Vassilij Veliki" in the town of Plovdiv, Bulgaria. The installation is situated on the flat roof of the building. It comprises 66 solar collectors, each of them with area 2 m2, with total area of 132 m2. The investment for the installation was provided within the framework of a 5-year Program of the Greek Government for Assistance to the Neighboring Countries. The aim is, by means of solar energy for heating the domestic hot water (DHW), to reduce the large expenses for energy bills and particularly for diesel oil. The results prove that the combined solar thermal installation with boilers on liquid fuels for DHW for a social house is a profitable socio-economic solution. This solution is economically attractive for the society. Besides, this action could be applied in all social houses, since the production of DHW is done on the base of local boilers on liquid fuel.
