A water heater is an essential part of any home. However, they are also one of the biggest energy users in your home. When you turn on your hot water heater, it uses as much energy as a refrigerator, freezer and light bulbs combined. This is because water heaters need to maintain a set temperature of at least 140 degrees Fahrenheit to be safe for use. Unfortunately, that high temperature also makes them one of the biggest energy users in your home. Fortunately, there are ways you can reduce their energy consumption. Here are some tips to help lower your water heater’s energy cost while still maintaining comfortable hot water at all times of the year.- Gathering Data First and foremost, you need to know how much your water heater is costing you in terms of energy consumption. There are lots of apps out there that will track your water heater’s energy usage, so take advantage of them! Another great resource is your local energy provider. They can let you know exactly how much you’re spending on water and what you can do to reduce that cost.- Install a Programmable Thermostat Programmable thermostats are remarkably easy to install and can save you a significant amount of money on your water heating bills. Programmable thermostats allow you to set the temperature of your water heater to match your usage. This means you can lower the temperature when you’re at home or on vacation, saving you a significant amount of energy.- Install a Programmable TimerIf you find yourself going out of the house for a couple hours each day, you can set your water heater to shut off during those times.- Don’t Run the Water until it’s ColdIf you’re in the middle of doing something and need a quick shower, don’t turn the hot water on right away.

Frequently Asked Question

While you technically can install a hot water heater yourself as a homeowner, the likelihood that this is a good or safe idea is very slim. Trust the professionals with your hot water heater installation to make sure it's done correctly. You wouldn't want to cause yourself or your family any harm.
The higher cost is a result of a more labor-intensive set-up, as new gas and water lines are required for installation. For a new tankless water heater, new electric wiring will need to be installed.
Turn off all water supplies in the house. Turn on all the hot water faucets in the house in order to drain what is left in the existing hot water heater. Then, disconnect the water line that connects the water heater to the rest of the house. There is often a connection on a hose that you can simply unscrew.
These heaters can be fueled by electricity, gas, or liquid propane and installed in many areas of your home. The national average cost to replace a 50-gallon water heater is $1,100 to $2,800, with most people paying around $1,800 for a direct replacement of a 50-gallon gas hot water heater using the same model.
  • Your older water heater is getting up there in age
  • It's making strange noises
  • You're getting rusty water out of the tap
  • Your hot water doesn't last as long as it used to
  • There are water puddles around the unit
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.
Turn up the thermostat on the hot water heater. One of the easiest ways to make a hot shower last longer is by using less hot water while it's at a higher temperature. To do this, turn up the temperature on the thermostat that's attached to the hot water heater tank. (Not the thermostat on the wall.)
Sediment buildup shortens the life of your water heater and adds to your energy bill by reducing its efficiency. Draining two or three gallons of water is usually enough to flush out sediments, but always let the water flow until you no longer see particles in the bucket. Regular water heater maintenance will always extend its lifespan.
  • You're overusing hot water.
  • The water heater tank size is too small for your household.
  • Your hot water heater is tankless.
  • Sediment or minerals have built up in your water heating system.
Soft water can actually corrode the water heater anode faster. When the anode wears down, the corrosive elements will move on to the tank. So if left alone, a water softener system can actually shorten the lifespan of a water heater.
