In order to avoid improper work of some appliances in pressure regulating stations, it is needed to heat up the gas stream before its pressure decrease. This is done by heating system, which consist of natural gas boiler, heat exchanger, pipes and the working medium that circulate in the system (describing in simple terms). Surfaces of thermally uninsulated heating system have temperature above ambient temperature, what could be the cause of heat loss. This paper presents the results of performed calculations, based on data obtained from the test rig, which has been mounted in the working pressure regulating station. Test rig has been designed in such a way, that it is possible to calculate total heat loss of the heating installation and thus determine the energy efficiency of natural gas heating process.
