Fig. 7From: Identification and classification of heat pump problems in the field and their implication for a user-centric problem recognitionProblem matrix for automated and assisted detection and solving. The main axes show potential for automated recognition based on smart meter data, and for assisted recognition of humans. Colours indicate actors who can typically solve problems. Filled bubbles show problems with energy conservation potential. Bubble sizes indicate the relative frequency of problems reported during the inspectionBack to article page
