This online course is meant for engineers, designers and utility owners who are dealing with pre-insulated district heating and district cooling networks. After passing the course participants will get all needed basic knowledge regarding pipeline design and engineering.
The course consists of 4 blocks - it is possible to pass all blocks or some specific blocks.
The course will be held online in English.
Lecturer: Aleksandr Ledvanov (HeatConsult, Technical director)

Aleksandr has more than 15-years experience in district heating design engineering. Under his leadership there were designed more than 500 km of pipelines at different part of the world - Scandinavia, Baltics, Germany and Latin America.
He is leading the one of the adaptations of the standard EN 13941 “District heating pipes”
