Even with regular care, a tank water heater will usually need to be replaced after about 12 to 15 years. Some water heaters last longer, while others may need replacement sooner depending on how heavily they are used, the quality of the water, the design of the unit and where it is installed.
If you’re wondering how old your water heater is, look for the date of manufacture on the tank. It is usually printed on a sticker containing other information about the unit. If you cannot find a date, Salmon Plumbing may be able to help determine the age using the manufacturer’s name and serial number.
The life of a water heater is highly dependent on usage. Every time the tank heats up, there is expansion and contraction that will eventually cause the tank to fail.
How Do I Know When to Replace My Water Heater?
There are Many Indicators that Signal it is Time to Replace your Water Heater:
- Erratic or inconsistent hot water. Your hot water temperature is erratic, or hot water runs out quicker than normal.
- Leaks around the base of the tank. Leaking around the base of the tank can indicate internal cracking or corrosion.
- Banging or rumbling noises. Calcium and sediment can build up on the bottom of the tank over time, creating a hard crust that causes noise during use.
- Coloured hot water from a faucet. If this occurs only when you run hot water, it may indicate that rust is developing inside the tank. Once corrosion begins inside the tank, there is no stopping it.
- Water is not as hot as it used to be. Sediment buildup can reduce the effectiveness of the heating elements or burners.
- The age of the unit. If the unit is over 12 years old, it is time to consider replacing it. You want to do this before you have a catastrophic failure.
- Unable to drain the tank. Sediment builds up inside the tank over time. If you are unable to drain the tank through the drain valve, it may indicate that sediment has built up enough to plug the drain.
Don't Wait Until Your Water Heater Fails
Since corrosion starts from the inside, out of sight, a complete failure can occur without warning. If your water heater is located in a finished basement, a failure can lead to substantial property damage.
Installing a catchment tray under the tank can provide an early warning of a leak and may help minimize damage. However, catchment trays are of limited value if they cannot be plumbed directly to a floor drain.
What Are the Benefits of Replacing My Water Heater?
Replacing an older water heater can provide several benefits:
- Better energy efficiency. A new water heater will generally operate more efficiently than an older unit, which can help reduce energy costs.
- The right size for your household. Your family's hot water needs may have changed since the existing unit was installed. A replacement gives you an opportunity to choose a tank with the appropriate capacity.
- More reliable hot water. A new water heater can provide more consistent hot water and reduce the likelihood of an unexpected failure.
- Avoid rental costs. If you're currently renting your water heater, purchasing your own unit may save you money over time.
- Peace of mind. Replacing an older water heater before it fails can reduce the risk of an unexpected leak and the potential for water damage.
What About a Tankless Water Heater?
If you’re replacing an older water heater, you may be wondering if a tankless water heater is a better option for your home. Tankless water heaters heat water as you need it, rather than storing a large tank of hot water.
There are several potential benefits to going tankless:
- Hot water on demand. A properly sized tankless water heater can provide a continuous supply of hot water, as long as the demand does not exceed the unit’s capacity.
- Energy efficiency. Because tankless units do not continually heat and maintain a tank of stored water, they can be more energy efficient in some homes.
- More space. Tankless water heaters are much smaller than conventional tanks and can free up valuable space.
- Longer service life. With proper maintenance, a quality tankless water heater can last longer than a conventional tank water heater.
However, tankless isn’t necessarily the right choice for every home. The initial installation cost can be higher, and the unit must be properly sized for your home’s hot water demand. Gas-powered units may also require changes to the gas supply or venting.
If you’re considering switching from a conventional tank to a tankless water heater, Salmon Plumbing can help you determine whether it is a good fit for your home and recommend the right size and type of unit.
If your water heater is getting older, showing signs of corrosion, or no longer providing the hot water your family needs, it may be time to consider replacement. Whether you choose a conventional tank or a tankless water heater, the right choice depends on your home’s hot water needs, available space and budget. Salmon Plumbing can help you evaluate your options and choose a water heater that is right for your home.
