ZW Energiteknik AB

ZW Energiteknik wants to contribute to an increased use of renewable energy sources with the goal to improve environmental conditions and to decrease the emission of CO₂. In their opinion, using both large and small centralised heating systems, i.e. district heating or local heating networks, can best do this. They intend also to contribute to the use of effective district heating networks. An important task for ZW Energiteknik is to reduce the use of primary energy in order to provide a safe and sustainable environment to our children. This is why they also think that solar heating systems and heat storage systems are given technologies for the future.

Some of their specialities are:

• analysing regional energy systems
• efficiency improvement of DH systems
• solar heating systems and seasonal heat storage systems
• system analyses for reduced use of energy
• lectures and education for rational use of energy.

Areas of expertise include: Regional Energy systems, Active Solar heating systems, District heating systems and CHP, Energy saving in Buildings. Environmental Benefits of energy systems.
