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.
Leaving hot water on all the time is typically not cheaper than heating it only when needed. Here are some key points to consider: Energy Costs: Keeping water hot continuously requires energy to maintain the temperature, which can lead to higher utility bills.
Heating hot water with electricity will cost a typical household about $50 per month. Also, small water leaks can quickly add up to hundreds of dollars on your bill, so be sure to fix leaky faucets as soon as you see them.

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.
Savings resulting from turning down your water heater temperature are based on reducing standby losses (heat lost from water heater into surrounding area). Set too high, or at 140ºF, your water heater can waste anywhere from $36 to $61 annually in standby heat losses.
What costs the most on your electric bill? Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill.

There's a couple of things you can do right away to trim costs on an existing hot water service. By reducing the amount of water you use, keeping a lid on the thermostat and connecting to cheaper energy – you can reduce hot water running costs.
Faulty fixtures or leaking connections and pipes can go unnoticed at the water heater because it is not an appliance you see every day. The leaks can become significant and result in an increase in the water usage bill and your energy usage bill.
There are a variety of factors which could lead to running out of hot water too quickly. If your hot water runs out too fast, you may have an issue with: Too much hot water demand from multiple sources at the same time. Sediment build up inside of your water heater tank.
Only heat the hot water twice a day
Try heating the water for an hour in the morning and an hour in the evening. Start the water heating about an hour before you need it. For example, if you shower at 08:30, start heating the water at 07:30. If you wash up in the evening at 19:30, then start the water heating at 18:30.
If you have an electric water heater, you can save an additional 5%-12% of energy by installing a timer that turns it off at night when you don't use hot water and/or during your utility's peak demand times. You can install a timer yourself. They can cost $60 or more, but they can pay for themselves in about 1 year.
Ideally you should heat your home to a temperature of at least 18 °C. This is particularly important if you have reduced mobility, are 65 or over, or have a health condition, such as heart or lung disease. Having room temperatures slightly over 18 °C could be good for your health.
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.
The maximum Department of Energy recommended water heater temperature setting you should never exceed is 140 degrees Fahrenheit. The lowest recommended setting should never be below 120 degrees Fahrenheit.
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.
