Article is devoted to increasing efficiency of heat supply systems. We demonstrate research results and an analysis of dependences of overall heat supply system performance indicators at various levels of equipment of consumers with the automated individual heating substations.

Deposits on surfaces of heat exchange equipment reduce the heat transfer coefficient, heat exchange efficiency, and lead to significant energy losses. The paper considers a hardware-software complex for monitoring the state of heat exchange surfaces. Studies were carried out using models of surfaces of heat exchange equipment – 400×160×2 mm steel plates, by the method of free vibrations. The studies have shown the possibility of using the method of free vibrations for the detection of deposits on the heat exchange equipment, which reduces energy losses and labor input of monitoring the condition of the surfaces of heat exchange equipment.

The method was experimentally tested on a pipe with excessive internal pressure. It is established that the main frequency of its free-damp vibrations increases with increasing internal pressure of the pipe. The method of conducting experimental studies is described, and the main results are presented.
