With funding from the EKSH's "HWT Energy and Climate Protection" funding program, research is being carried out into how heat pumps can be increasingly used to heat water in renovated existing blocks of flats. This often fails due to hygiene requirements, which demand very high water temperatures for thermal disinfection, although only a maximum of 40°C is required for showering, for example. The partners will validate a method for predicting the risk of occurrence of the drinking water pathogen Legionella. It can then be determined whether hygienic hot water can also be prepared in this building at lower temperatures, e.g. using an ultrafiltration system. The method is intended to safeguard energy-efficient refurbishments before the start of measures.
The overarching goal is to achieve significant savings in heating requirements and to cover heating requirements with electricity-powered heat pumps. The "Energiewenderecht" group is also investigating the extent to which the existing legal framework promotes or hinders such concepts and, if necessary, deriving legal policy requirements.
The project was presented at the Future Energies Science Match (from 5:06:16 h).
