Abstract
Formulas were developed for determination of loss of heat in district heating pipes on the basis of thermographic examinations. The standard deviation for loss of heat defined on the basis of thermography is approx 55 W/m. The purpose of the present examination has been to test the method from project report no. 32 ``Thermographic examination of district heating pipes`` on an actual district heating network. The conclusion is that estimation of loss of heat on the basis of thermographic data definitely seems to be a qualified method for estimating and deciding the priority of the renovation work for a district heating network. Reduction of uncertainty can be obtained by carrying out more examinations on the same section, possibly at different times, to minimize uncertainties arising from climatic affects. The thermographic examination can be supplemented with thermometer measurement on the surfacing. The examination shows, however, that both methods would presumably lead to the same priority of renovation work. (AB).
