Evaluations of economic interventions usually focus on one target behavior. This study extends the evaluation scope to multiple untargeted behaviors. We evaluate a hot water saving intervention in a natural field experiment. Despite an exclusive focus on hot water, the intervention changes multiple behaviors. Notably, we find a 5.6 percent reduction in room heating energy consumption that persists one year after the intervention. We show that the room heating spillover has important welfare implications.
