A water heater is one of the most important pieces of equipment in your home. It has the important job of heating the water that you and your family use for bathing, cooking, cleaning and other daily tasks. However, to keep it running efficiently and safely, you need to service it regularly. Regular water heater service will help avoid costly repairs in the future. When your water heater breaks or leaks, it can be inconvenient and costly to fix. And if left unchecked, it can lead to serious health risks like scalding and carbon monoxide poisoning. Fortunately, most water heaters last for 10 to 15 years before needing to be replaced. That said, it’s important to have yours checked out by a professional at least once a year to make sure it’s working properly, as well as to find out if there are any repairs or replacements that need to be done before the end of its lifespan. Here’s what you need to know about water heater maintenance and when you should perform it.

What to expect during a water heater service visit

Water heater service appointments generally fall into one of three categories: inspection, cleaning or repair. During an inspection, you’ll likely have your water heater’s gas regulator checked, as well as the thermostat and its associated temperature-control mechanism. These are important pieces of equipment that help regulate the amount of gas going into the water heater. If your water heater has a plastic or rubber float switch instead of a thermostat, a technician will use a special tool to check the switch for water pressure. If your water heater has an electric or hybrid water heater, there is no need to have a technician inspect it for gas pressure. In either case, a technician will check the water heater’s water level. If the water level is too low, there may be a problem with the water heater’s fill valve.

Maintenance by season

Whether you’re in the middle of winter or summer, it’s important to know which type of water heater you have and when to service it.Rainwater-storage tank - A rainwater-storage tank is a great way to reduce the amount of water you use to landscape, water your garden or fill your swimming pool. However, these tanks are not designed to be used as a primary source of hot water in your home. Rainwater-storage tanks require a large amount of space and can be very expensive, especially if you want to install a high-capacity tank.If you have a rainwater-storage tank, you should have a professional check its water level at least once a year to make sure it isn’t running low. If there’s less than two inches of water in the tank, the water may not be hot enough to comfortably use for bathing, cleaning and other hot water tasks.- Electric water heaters - Electric water heaters can be a great choice if you want to reduce your water use or make a budget-friendly upgrade to your home’s hot-water supply system. Some electric water heaters can be programmed to turn on and off automatically to reduce energy usage. However, an electric water heater may not be a good fit if you live in a house that doesn’t have easy access to an electrical outlet. If you want to use a hybrid water heater, you’ll still have to schedule a service appointment at least once a year to make sure it’s running properly.- Natural gas water heaters - Natural gas water heaters are probably the most common type of water heater. They come in different sizes and are typically installed by a professional. If you have a natural gas water heater, you’ll typically have a gas supply valve in your home’s crawlspace or basement. You can turn the supply off remotely with a timer or thermostat, or you can have a technician come out to service the unit if it breaks down.

When to replace your water heater

The general rule is that you should replace your water heater before the 10-year mark. However, there are many factors to consider when deciding when to replace your water heater, including the number of people in your home, the type of water fixtures in your home and the type of water heater you have installed.If you have a large family or live in a high-rise or high-occupancy building, your water heater will be running non-stop. These households typically have larger water demands, which can shorten the lifespan of your water heater. If you have a water softener, you’ll also want to consider the salt content in the water when deciding when to replace your water heater — especially if you have a salt-water softener that uses a large amount of salt.If you’re on a budget, it’s best to wait until your water heater is 10 years old, but if you’re in the process of selling your home and want to make the sale as soon as possible, you may want to consider replacing your water heater sooner.

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.
