Connection of Prosumers in Høje Taastrup

,
The transition to low-temperature supply in district heating networks as well as the transition towards renewable heat sources require new technical solutions that allow the introduction of new actors in the district heating sector. These new actors are defined as prosumers that are both connected to the district heating network as consumers and can deliver heat to the network. In Høje-Taastrup Municipality, different prosumers are already connected or in the process to be connected to the district heating and cooling network.

A smart energy system coming to place in Høje-Taastrup

, ,
In this video you will see how low-temperature district heating and large heat pumps are an essential element in Høje Taastrup District Heating and Høje-Taastrup Municipality's collaborative journey towards an efficient, flexible and smart energy system.

New innovative main line with heat recovery

,
On the demonstration site in Høje-Taastrup municipality a new type of multimedia pipe system with heat recovery has been installed in the distribution network. The product developed shows that it is possible to integrate collector pipes in standard district heating pipes to recover heat and minimise heat loss.
The image shows how the installation of the LTDH-service pipes in Osterby are close to the users' buildings in order to reduce the length of the network and consequently the heat losses.

From traditional DH to LTDH in Østerby

, , , ,
A new low-temperature network has been designed to upgrade the old and obsolete traditional district heating-network in Høje-Taastrup. This report provides information about the final design and the implementation of the low-temperature district heating network and can be used as a guideline of the installation process for future similar projects.

From the tradition to the future: the Østerby case

A new LTDH-grid is built in the district in Høje-Taastrup, Denmark. The standard and old district heating systems are replaced by low-temperature district heating (LTDH) or ultra-low-temperature district heating (ULTDH) networks. Discover how in this webinar.
