The paper considers a mathematical model of the temperature distribution over the heating pipe to estimate the actual parameters of the heating system based on the results of temperature measurements. An example of solving the problem of actual flow rate identifying of the coolant in the risers, the temperature at the entrance to each riser and the shunt coefficients of the radiators of the heating system of the building is given. Identification results are used to diagnose the condition of the heating system.
