The Basel-based energy supplier IWB is launching the nano-network as a new solution for heating outside the district heating supply in the canton of Basel-Stadt. According to a press release, when heating systems are replaced in houses or terraced houses that are close together, the heating systems are connected to each other and equipped with a central control system. IWB presented the nano-network to interested owners from the Mausacker district in Reinach for the first time on Wednesday, 6 March.
As a rule, each property owner takes care of their own heating system. According to the press release, the individual heating systems are often oversized for safety reasons. Installation and heating costs are higher than necessary. In a nano-network, the heating systems of two to eight properties are physically connected and supplemented by an intelligent control system. All types of heating systems can be connected together.
The control system ensures that the systems that provide environmentally friendly heating are used first. All connected owners can obtain an overview of energy production, consumption and costs at any time via an Internet application. In a second step, old, fossil-fuelled heating systems can be decommissioned.
In a pilot project, the merger of three properties resulted in financial savings of up to 15 per cent. In addition, the three properties, in which a heat pump, solar thermal systems and gas heating systems were installed, were able to heat 90 per cent renewably as a result of the merger.
