If your tank leaks, you need a new water heater. For an electric water heater, you also might consider insulating underneath the tank as well. A ridged piece of insulation (or bottom board) will help prevent heat loss into the floor, and could save you another 4%–9% of water heating energy.

How can energy loss be reduced in a hot water tank?
Reduce Heat Loss from Hot Water System
Distribution pipes can also lead to energy losses, as it is estimated that the water temperature drops 2°F – 4°F between the source and the point of use. Consider adding extra insulation or installing custom pipes to reduce this heat loss (this is a project you can do yourself).

Does wrapping your water heater really save energy?
Water heater insulation could reduce standby heat losses by 25%–45% and save you about 7%–16% in water heating costs—and should pay for itself in about a year. You can find pre-cut jackets or blankets available from around $20.
Does turning off water heater at night save money?
Turning off your water heater, like many other electrical appliances, can save you money each month on your bill. A small amount of heat escapes when the water heater is turned on, even though it’s well insulated.
What temperature should I set my water heater?
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.

Why is my water heater running out of hot water so quickly?
Sediment is formed from loose minerals that are found naturally in water. When they settle at the bottom of the tank, it causes your tank to run out of hot water quickly. Sediment can be things such as sand, silt, or rust that take up space in your water tank. As a result, your hot water supply dwindles.
Why doesn’t my hot water stay hot long?
One of the leading plumbing problems with a hot water system is a poorly maintained hot water tank. Sediment and corrosion build up within the tank. This lowers the water quality and slows the heating element’s effects. A simple draining and cleaning process resolves these plumbing problems.
Why is my hot water getting cold so fast?
If you’ve noticed that your hot water is suddenly turning cold after a very short amount of time, the most likely cause is a broken dip tube inside your hot water heater.
Does insulating your hot water pipes help?
Insulating your hot water pipes reduces heat loss and can raise water temperature 2°F–4°F hotter than uninsulated pipes can deliver, allowing you to lower your water temperature setting. You also won’t have to wait as long for hot water when you turn on a faucet or showerhead, which helps conserve water.
Should I insulate under my water tank?
All cold storage tanks in the loft, including central heating expansion tanks, and all water pipes, including overflows, must be insulated. Do not insulate the floor of the loft under the tanks, heat coming up from the area below should help prevent the tanks freezing.
What does a water heater blanket do?
An insulation blanket, or hot water heater blanket, is exactly what it sounds like. It’s a blanket that wraps around your hot water heater to keep it from losing heat. It also helps your hot water heater to maintain a consistent temperature.

Can you cover a hot water heater?
Curtains. Perhaps the simplest way to hide your furnace and water heater is to add a sliding curtain as a divider.
