Home Energy Briefs: #5 Water Heating

Jump to Section

This Home Energy Brief covers water heating. The brief goes over storage tank heaters, demand water heaters, solar thermal water heating, heat pump water heaters, and drain-water heat recovery. You can save money immediately by changing how you use your hot water, for example, by lowering the temperature on your hot water tank, using cold water to wash your clothes, and/or insulating your hot water heater and pipes. Installing new and more efficient technologies and devices can also help save money. Such technologies and devices range from efficient showerheads and aerators to the installation of new efficient water heaters, heat pumps, solar water heaters, or drain-water heat recovery systems. As of 2012, the Home Energy Briefs have been updated and adapted to Southern California Edison’s Online Home Energy Guide.
