Last updated at June 8, 2019 by Teachoo.Your water heater is one of the more robust consumers of energy among your home appliances. If you can calculate how much energy you expend heating water, however, you will be armed with the information you need to improve your efficiency and bring your bills down to a minimum.How much electricity do our appliances use? You can usually find the wattage of most appliances on the nameplate on the back or bottom of the appliance. EXAMPLE. If John uses a window fan (200 watts) 4 hours a day for 120 days per year, how much does it cost him to 120V. 1500W. scanner.Your electric heater wattage tells how much electricity is needed to power it. Most electric heaters use 1,500 watts, but some are slightly less or slightly more. However, your electric bill is measured in kilowatt hours, which is the amount of energy used while running a 1-kilowatt appliance for one hour.
