Choosing a Chimney Liner

When it comes to choosing a chimney liner, the size, height and construction materials will make a big difference. They must be sized properly to vent the gases, and they also need to be the right material to handle temperature variances.

Before you decide to buy a generic chimney liner at the home improvement store and try to drop it in place, here’s what you should know about this vertical shaft.

Choosing a Chimney Liner | Let the Professionals Help with Sizing

If you’re working with a wood- or coal-burning stove, then you’ll need a liner that matches the diameter of the exhaust hole.

However, it gets a little more complicated when you’re working with gas- or oil-burners. With these systems, you’ll need to know the: choosing a chimney liner
•Gallons per hour firing rate
•Chimney height
•Lateral distance between appliance and chimney
•Steady-state efficiency rating

Specific formulas are used to determine what size the liner should be, but our professionals can help you with this process.

Insulated or Plain
Insulated chimney liners are ideal for improving the unit efficiency. The insulation reduces the buildup of creosote inside the flue to reduce the risk of fires.

You’ll also find that heat is maintained inside the flue better, so your home will have an added layer of protection.

Clay Liners
Clay tiles have historically been used in chimneys, and this may be what you’re currently dealing with if you have an older home.

While they were designed to last up to 50 years, they will eventually need some attention or a new liner. Most people will switch to a different type of liner when the time comes.

Cast-in-place Liners
These liners have additional insulation, but they’re also prone to cracking. While they are less likely to develop creosote, they’re also very expensive.

If your chimney has any bends in it, then the price will rise further. They’re also more likely to require repairs or relining down the road due to their tendency to crack.

Metal Liners
Metal liners are the favorite option of builders and renovation companies today. They’re available in all types of shapes and sizes, so they can be used in almost every application.

The parts are cost-effective and affordable, so most homeowners can afford to make this switch. If it’s time to replace your chimney liner, then you may decide that the metal liner is a fast and affordable option that’s also highly effective and safe.

Choosing a Chimney Liner | Why?

When a liner that’s too small is used, the chimney won’t get the air it needs to keep a good fire going. Chimney liners that are too large tend to have more problems with creosote build-up and cold drafts. Getting the liner resized properly will help your fires burn clean.

Liners must be replaced when they become cracked or damaged. If the liner has lost structural integrity, then gases may be released back into your home and living environment.

If the chimney is dedicated to one appliance, then you may choose to stop using that appliance until you can get the liner checked. However, this won’t be an effective choice if a single chimney is used for multiple appliances, such as your furnace, another fireplace, or a wood burning stove on another floor.
