Local heating network for the Rohrhammerweg residential area, Sömmerda.

For the residential area "Rohrhammerweg" the construction of a local heating supply with a CHP from the Sömmerda outdoor pool is planned. The planned local heating center of the residential area was merged with the heating center of the bathroom in the planning. The heat is generated 100% with

A natural gas-powered combined heat and power plant in combination with a gas heat pump. Only for peak load protection when commissioning the

A condensing gas boiler will be installed to provide redundancy for the generators mentioned. The electricity generated by the CHP is used during the

Operation in the outdoor pool and the surpluses in the network of the municipal utilities are consumed.

Location heat generation

The CHP and the condensing boiler are set up in building 6, local heating center / storage building. From there, an internal local heating network will be set up, which will supply the swimming pool and an external local heating network, which will supply the residents of Rohrhammerweg.

Local heating network supplying residents

A local heating pipe will be laid from building 6 in the outdoor pool to the property boundary of Rohrhammerweg. This is where the services of the contractor (your services) tie in. The local heating line to be continued is to consist of 2 UNO pipes, PE-Xa with a plastic jacket and PU foam insulation. The individual house exits are made via T-pieces made of black steel in the parallel branch design. Each house connection has a shut-off valve in the flow and return, which are accessible via street caps. The further lines from the branch of the main route to the building are made of steel. The head holes for building entry are made on site.

The contractor is responsible for the core drilling for the implementation of the pipe cups through the outer wall. Likewise the sealing of the house connections in / on

Masonry.

At the end of the main route, a temporary short-circuit section will be installed in order to allow the heating medium water to circulate. The lines must be laid without any height jumps, if possible with a slight incline from the boiler house to the last consumer in order to avoid the formation of air pockets.
