Water heaters are among the highest energy-consuming appliances in your home. Energy star predicts that households spend between $400 and $600 on
Water heating accounts for about 18% of your home's energy use and is the typically the second largest energy expense in any home. You can reduce your water heating bills in four primary ways: Using less hot water. Using energy-saving strategies, such as turning down the thermostat on your water heater.

Heating and cooling: 45-50%
The largest electricity consumer in the average household is your heating and cooling appliance. By a long shot. Central air conditioners and heaters use tons of energy in order to keep your home set to the right temperature.
According to the U.S. Department of Energy, about 18% of your electricity costs are directly tied to your water heating system.
Leaks and long pipes can increase your water usage. The water heater unit may be one of the largest energy-using appliances in your home, but it may result in higher bills for other utilities in your home as well.
Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
According to the U.S. Department of Energy, standby power accounts for as much as 5% to 10% of residential energy use, and homeowners could save $100 to $200 each year on utility bills by unplugging devices that aren't in use.
In terms of your water heater, how quickly it heats water determines the overall energy efficiency of your unit. If your heater is taking too long to warm up the water for use throughout your home, it can send your electricity bill skyrocketing.
Set too high, or at 140ºF, your water heater can waste anywhere from $36 to $61 annually in standby heat losses. Additional savings will be realized by the lower temperature for consumption (from water demand or use in your home, such as clothes washing, showers, and dishwashing). These may amount to more than $400.
Newer models require specialized tools and training to install, and the associated labor costs can add up quickly, making the total cost of the water heater higher than you expected. Be sure to ask about installation costs and if it includes special fees like additional pipes, wiring, or permits.
Heating water with electricity is expensive when compared to gas or even oil. Leaving your immersion heater on all the time can be a waste of energy.
Having a water heater that's too big or too small for your household is one of the main reasons you may be seeing higher energy bills. On average, a 30-gallon tank is sufficient for 2 people, a 40-gallon tank is good for 3-4 people, and a 50-gallon tank suits 4-5 people.
Typically, a hot water heater that uses a tank will run for 3 to 5 hours per day. So, a 4,000-watt heater used for 3 hours a day at 10¢ per kWh will cost $1.20 per day, about $36.50 per month, or $438 per year.
Air conditioning uses the most electricity in a home in every region of the US and accounts for 15-23% of the average household consumption. At around 12.5%, space heating has the second largest share of consumption in every region except the South.
The most common contributing factors are outdated appliances, thermostats, lightbulbs, or insufficient insulation. Here's what you can do to help reduce your household energy usage.
The Givoni or Woods diagrams show a direct relationship between air speed and the drop in temperature felt by users of the room. In this case, a ceiling fan will consume between 20 and 50 watts (still a long way from the consumption of an air-conditioning system (800 to 1500 watts, i.e. 30 to 40 times more).
Your electric bill is likely to account for the highest expense on your monthly utility bill. Most Americans find their electricity usage is 41% heating and cooling, so that's often the biggest expense.
120 degrees Fahrenheit is the safety recommendation against scalding, but 140° is the common default setting. Most experts agree that anything below 120 degrees creates a risk for bacteria to develop inside your water heater from stagnant water, such as legionella that causes Legionnaire's disease.
Turning your water heater off completely when it's not in use can help you save a small amount of money each month on your energy bills, but the hassle of manually turning your unit off and on typically outweighs the benefits.
