District heating networks done right the first time
Established in 1976, Warmnet Oy is a specialist district heating contractor. We design, build, install, renew, maintain and repair district heating networks as turnkey deliveries or clearly defined work packages. Operating from our locations in Varkaus and Hamina, we serve energy companies, cities, municipalities and industrial operators throughout Finland.
Turnkey delivery or a defined project scope
Every stage of a district heating project must work seamlessly with the next. Design, material supply, civil works, transport, lifting operations, pipe installation, welding, insulation and tie-ins must be carefully coordinated to ensure safe completion and keep the entire project under control.
When the client needs a complete solution, Warmnet brings all these stages together under one contract. We also undertake clearly defined parts of a project, such as pipe installation, maintenance, repairs or other separately agreed work. The principle is always the same: the scope is agreed clearly, and the work is completed to a professional standard.
Experience that makes the difference in demanding district heating projects
Warmnet began operating in 1976. Over five decades, we have worked on a wide range of district heating networks, long transmission mains, large-diameter pipelines, network renewal projects, bridge installations, water crossings and projects in industrial environments.
For our clients, this experience means a practical understanding of how the work should be planned, what equipment each site requires and how to keep the project moving even when the environment, pipe diameter or schedule makes it particularly demanding.
A proven track record across Finland
Warmnet's references include transmission mains extending over several kilometres, DN400–DN600 pipelines, turnkey projects, bridge installations and water crossings, as well as projects at data centres, ports and industrial sites.
These projects demonstrate that our people, working methods and equipment perform reliably even in demanding district heating projects throughout Finland.
When problems arise, you need a contractor that knows district heating networks
District heating network faults do not always occur during normal working hours. When needed, Warmnet can provide assistance outside regular working hours, including evenings and weekends. Our stock of commonly used district heating materials and supplies supports a rapid response in urgent situations.
Every repair requirement is assessed according to the site and the situation. Contact us when you need an experienced contractor's expertise in network maintenance, repairs or urgent work.
Long-standing client relationships reflect the quality of our work
Warmnet works with energy companies, cities, municipalities and industrial operators. We carry out individual projects as well as work under annual contracts. Our longest client relationships date back to the 1970s.
Long-term cooperation is built on completing the agreed work properly, maintaining clear communication and being able to respond when circumstances change. This is what we mean by getting the job done right the first time.
