Fjärrvärme har en betydande roll i det svenska energisystemet där många är beroende av att systemet ska fungera optimalt. Trots den generellt höga leveranssäkerheten i dagens system är oplanerade leveransavbrott är något som sker tidvis. I Sverige började många fjärrvärmenät byggas ut i mitten av 1900-talet och mängden skador i äldre ledningar förväntas öka med tiden. Att ersätta gamla ledningar iDistrict heating plays a significant role in the Swedish energysystem where many are dependent on the district heating working optimally. The system in general has a high security of supply, but unplanned interuptions in the supply do ocasionally occur. Many of the district heating networks in Sweden began construction in the middle of the last century and some of the old pipes are expected to see
