On-Site Thermal Diagnostics Of Heating And Dhw Installations

The requirements for the inspection of heating systems have been introduced in the Energy Performance Act. Thermal diagnostics of the system is an evaluation of the technical conditions of the heating and hot water installations, due to their energy efficiency and reliability of obtaining the required internal temperature in the building and delivery of the right amount of domestic hot water at the proper temperature. Data obtained from the diagnostics are useful for proper energy-efficient operation of the installation, for determining the energy performance of the building and executing the energy audit of the building for thermomodernization purposes. The paper describes the methodology of comprehensive inspection and diagnostics of heating and DHW systems and outlines the scope of basic activities that should be performed. The practical application of such diagnostics in several buildings is also presented.
