人们普遍认为，关闭电热水器（在没有需求的情况下）是没有好处的，除非长时间关闭。现在展示了在一天的短时间内通过停产实现的节约。这些都是基于对水套（备用）损耗和电热水器不稳定响应的简单分析。引文:伊利诺伊州芝加哥ASHRAE Transactions第83卷第1部分

There is a general feeling that shutdown of electric water heaters (in theabsence of a demand) is not beneficial unless for extensive periods of time.The savings realizable through shutdowns in periods as short as fractionsof a day are now presented. These are based on a simple analysis of thejacket (stand-by) losses and the unsteady response of an electric water heater.
