Determinants of households' space heating type: A discrete choice analysis for German households

Considering the increasing attention on efficient use of energy, it becomes vitally important to understand the energy-related behavior of households. This article presents empirical evidence on the determinants of the space heating technology applied by a household. Three sets of variables are examined as potential influences--building, socio-economic, and regional characteristics. To highlight both the differences and similarities, the results are obtained from a sample of house owners, and from a sample including all households. The influence of socio-economic factors is similar across these groups. Income is found to exert only a minor impact on the system choice. Dwelling features are significant in determining the heating type, particularly in the sample including all households. Regional effects are important--clear differences prevail between East and West Germany.
