External piping – design, sizing, and renewal for housing companies

When should external building pipes be replaced?

In many row house and semi-detached housing companies, a large portion of the heating and domestic water network pipes run underground outside the buildings. These external pipes are vulnerable to moisture, frost heaving, soil settlement, and external damage. As the piping ages, the insulation and protective structures of the pipes also deteriorate, which can increase energy consumption and raise the risk of leaks. External piping typically includes the pipes for the heating network, domestic water network, and ventilation heating network.

Exterior pipes are usually renewed either due to leaks or based on the age of the piping. During renewal, it is crucial that the pipe sizing, components, and installation methods are selected technically correctly. Proper sizing and professional implementation directly affect the network’s functionality, adjustability, and longevity.
