Report a fault in the district heating network

How to identify a district heating network fault

Because district heating is distributed through underground pipes, water leaks are not always easy to detect. However, there are several signs that anyone can look out for which may indicate a leak.

Heavy steam formation

It is normal for steam to rise from the district heating network's vent pipes, especially during very cold weather. However, if you notice unusually heavy steam coming from a location that is normally familiar to you, it may indicate a leak. The vent pipes are metal posts about one metre high, located throughout the city. The newest ones have a metal sphere at the top.

Green-coloured water

If you notice that the ground, natural water, snow or tap water has turned green, it is likely to be a district heating leak. A dye is added to the water in Turku Energia's district heating network, giving it a yellowish-green colour. The dye is odourless, non-toxic, harmless to human health and does not harm the environment.

A snow-free area in otherwise snowy surroundings

If you notice a patch of ground without snow or ice during winter, while the surrounding area is snow-covered, it may indicate a district heating leak. The water in the district heating network is hot enough to melt the snow and ice at the site of the leak.
