A water heater chimney liner is a necessary component of your home’s ventilation system. Its primary purpose is to prevent dangerous gases from leaking into your home, but it also plays a role in the efficiency of your water heater. If you have an older home with an unlined chimney, or if your liner has become damaged, it’s important to have it replaced.
If your water heater is over 20 years old, it’s time to start thinking about replacing the chimney liner. The average lifespan of a water heater is only 10-15 years, so if yours is getting up there in age, it’s definitely time to start shopping around for a replacement.
One thing you’ll need to consider when shopping for a new water heater is the type of chimney liner you’ll need.
There are two main types of chimney liners – metal and clay. Clay liners are the most common type of liner and are typically less expensive than metal liners. However, they’re also more susceptible to damage from acidic gases and can crack over time.
Metal liners, on the other hand, are much more durable and can last up to 50 years with proper care. They’re also less likely to be damaged by acidic gases.
So, which type of chimney liner is right for you?
If you have an older home with a clay liner, you may want to consider upgrading to a metal liner. If your home is newer or if you have a gas water heater, then a clay liner will probably suffice. Ultimately, it’s up to you and your budget!

Is a Chimney Liner Required for a Hot Water Heater?
If you have a hot water heater, you may be wondering if you need a chimney liner. The answer is maybe. If your hot water heater vents into a masonry chimney, then it is likely that you already have a suitable liner in place.
However, if your hot water heater vents into a metal chimney, you may need to install a liner to protect the metal from corrosion. In some cases, installing a stainless steel liner can also improve the efficiency of your hot water heater.
Can You Vent a Water Heater into a Chimney?
If you have a gas water heater, you can vent it into a chimney. If you have an electric water heater, you cannot vent it into a chimney.
What Size Chimney Liner Do I Need for a Water Heater?
There are a few things to consider when selecting the size of your chimney liner. The first is the BTU output of your water heater. This will help determine the amount of flue gases that need to be vented out of your home.
The next thing to consider is the height of your chimney. This will help determine the draft that is needed to vent the flue gases out of your home. The last thing to consider is the type of fuel that you are using for your water heater.
This will help determine the temperature of the flue gases and how corrosive they may be.
The most common type of fuel used in residential water heaters is natural gas. Natural gas has a lower combustion temperature than other fuels, such as oil or propane.
This means that the flue gases produced by a natural gas water heater are less corrosive than those produced by other types of fuel-fired water heaters. As a result, most homeowners can use a smaller diameter chimney liner when venting a natural gas water heater.
The table below shows recommended minimum chimney liner diameters for different combinations ofBTUhoutput and Chimney Height:
Minimum Chimney Liner Diameter (inches)
BTUh Output 0-4 ft 5-8 ft 9-12 ft 13+ ft
Up to 30,000 3 4 5 6
30,001 – 50,000 4 5 6 7
50,001 – 70,000 5 6 7 8
How Much Does It Cost to Install Chimney Liner?
The cost of installing a chimney liner varies depending on the type and size of liner you need, as well as the complexity of your chimney. Generally, you can expect to pay between $500 and $2000 for most installations.
There are three main types of chimney liners: metal, clay tile, and poured-in-place concrete.
Metal is the most common type of liner, as it is less expensive than the other options and easy to install. Clay tile is more expensive than metal but offers better insulation. Poured-in-place concrete is the most expensive option but provides the best insulation and protection from weathering damage.
The size of your chimney also affects the cost of installation. A smaller chimney will require a shorter liner, which will be less expensive than a longer one. If your chimney is particularly complex or difficult to access, this may also increase the cost of installation.
Installing a new chimney liner is generally a fairly straightforward process that can be completed in one or two days. However, if your chimney is in poor condition or has significant damage, it may need to be repaired before a new liner can be installed. This can add to the overall cost of the project but is necessary to ensure that your new liner will function properly and last for many years to come.
