This page is simply figures and calculations, and is of limited interest. By the way, you can get a thermostatic shower valve to keep the water temperature constant even when people flush toilets or turn on sinks in other parts of the house. On a separate page I have questions I've received and answered about how saving on water heating costs. How much energy stuff uses How to measure electrical use Mr. All Rights Reserved.

If a heater has two elements, people sometimes assume that they should add their wattage to get the total power consumption of the heater. This isn't correct, because both elements don't come on at the same time. A heater with two elements and a label that specifies a power usage of 4, watts for each element uses a maximum of 4, -- not 9, -- watts.
