Shallow burial of district heating pipes
Paper in proceeding, 2008

The aim with this paper was to study if the investment costs for district heating installations in suburban areas can be lowered with more rational construction work. A field trial was done with four twin pipes of dimension 2xDN32/160 laid between 600 mm and 180 mm below the asphalt surface in a road with heavy traffic. The conclusion is that shallow burial lowers the investment costs and is technically possible if the road structure is properly built.
