Flexanet district networks on coil are our strikingly efficient, high-speed solutions for district heating, cooling and potable water networks – both for newbuild and renovation projects. A fully prefabricated Flexalen network with readily attached house connections is the all-inclusive pre-insulated network solution that can be swiftly rolled out to connect an entire street in just one day.

Turnkey district heating – for minimum risk and maximum lifetime

What’s usually the most complicated and time-consuming part of installing district networks is an easy and reliable fix with Flexanet district networks on coil. 60-70% of the connections are made in the controlled factory environment. The connections are readily attached to the main line, and carefully pressure tested. This means risk, maintenance and overhead costs are kept to an absolute minimum.

At full speed ahead with Street in a Day

Flexanet prefabricated networks ensure maximum speed and reliability in the implementation of district heating networks. They can be rolled out from the coil directly into to the trench, allowing instant connections to the houses. The entire installation – including trenching, laying, welding and closing – can be done in just a single day, ensuring minimal disturbance for residents, businesses and the built environment.


We’ve been breaking records in various district heating projects across the globe. Here's what we did in Hengelo, the Netherlands:
