Using electricity for heating can contribute to decarbonization and provide flexibility to integrate variable re-newable energy. We analyze the case of electric storage heaters in German 2030 scenarios with an open-sourceelectricity sector model. We find that flexible electric heaters generally increase the use of generation tech-nologies with low variable costs, which are not necessarily renewables. Yet making customary night-time storageheaters temporally more flexible offers only moderate benefits because renewable availability during daytime islimited in the heating season. Respective investment costs accordingly have to be very low in order to realizetotal system cost benefits. As storage heaters feature only short-term heat storage, they also cannot reconcile theseasonal mismatch of heat demand in winter and high renewable availability in summer. Future research shouldevaluate the benefits of longer-term heat storage.
