Abstract

This paper investigates the technical and economic potential of raising the energy efficiency of domestic electric water heaters in the European Union.

This paper reports intermediate results from an on-going SAVE sponsored study to investigate the technical and economic potential of measures to raise the energy efficiency of domestic electric water heaters in the EU. After refrigeration, electric water heating constitutes the second most important residential electric end-use, accounting for ~18% of all EU domestic electricity consumption (~70TWh/year).
