Low-loss cost-efficient piping system for local district heating distribution systems.

When heating energy demand gets lower than a certain threshold the traditional district heating system solutions can not longer be used to serve the buildings in a viable way for two reasons:
1. The losses in the distribution get too high in relation to the demand that is covered,
2. The expenses in installing the distribution system are too high in relation to the load covered, which means that the fixed heating energy price will have to be unreasonably high to pay for the installation over the payment period. On this background the objective is to develop the distribution pipes and connection system - for a dense, low-rise housing area - to become technically and economically viable – also for ultra low-energy dwellings.

The work is ongoing.
