Nowadays, in Romania, centralized district heating is still widely used in many Romanian cities. All the heating facilities were made during 1950-1970. The whole system is largely improper due to large amounts of heat leakage, lack of heat and energy efficiency measures and financial shortages. All these limitations are made worst due to the continuous limitation of resources and also due to the high price of the energy. By taking this aspects in consideration, the measurement and the management of the heating agent is a real priority for the power plants and also for the heating distribution companies from Romania. The construction of small and efficient cogenerative plants is another major issue for the municipalities. There is a huge trend in the Romanian district heating industry to introduce as many as possible IT and TC solutions, or excellent measuring capacities. This paper presents human-machine interface, conceived by the authors and applied in the case of the small Power Plant located in Freidorf-Timisoara. Starting from computer science, computer graphics and thermal engineering, to electronics and electrical engineering, this paper is a true example of a multidisciplinary research.
