Will My Chimney Need to be Relined with A New Furnace? 

So, your old furnace finally gave up the ghost, and you are spending your time pricing new furnaces on the internet. It may have occurred to you that your chimney is involved in the process of replacing your furnace. You may be asking yourself- will my chimney need to be relined with a new furnace? It’s a legitimate question, so let’s investigate further.

chimney relining in Groveville NJThe Role of Your Chimney with a New Furnace

Traditionally, chimneys serve as the pathway for smoke, combustion gases, and other byproducts to exit your home safely. However, with advancements in furnace technology, the requirements for these pathways have changed. Modern furnaces, especially high-efficiency models, often produce lower exhaust temperatures, which can lead to condensation and potential damage inside traditional chimneys not equipped to handle this change.

Indications Your Chimney Needs Relining

Several factors indicate the necessity for chimney relining when installing a new furnace. These include:

Compatibility and Safety

If your new furnace is a high-efficiency model, it’s likely designed to vent exhaust in a way that’s incompatible with your existing chimney without a liner. Relining is crucial to ensure these exhaust gases are safely ushered outside, eliminating potential health hazards.

Building Regulations and Codes

Local building codes often have strict requirements regarding furnace installations and chimney linings. These codes are designed to ensure both safety and efficiency and must be observed.

Chimney Inspection Results

A chimney inspection by a qualified chimney sweep service can reveal issues such as cracks, deterioration, or improper sizing for your new furnace. These problems often necessitate relining to ensure safe and efficient operation.

Types of Chimney Liners

When it comes to relining your chimney, there are a number of materials and types to consider, each with its advantages and considerations:

Metal Chimney Liners

Metal chimney liners are usually made from stainless steel or aluminum. They are durable, resistant to corrosion, and suitable for gas and oil furnaces. Metal chimney liners are a popular choice for their longevity and easy installation.

Clay Tile Chimney Liners

While more traditional, clay tile liners are less suited to the lower temperatures and increased condensation modern furnaces produce. They are commonly used in older homes and might require replacement or modification for new furnace installations.

Cast-in-Place Chimney Liners

Cast-in-place chimney liners provide a seamless, insulated path for exhaust gases, improving a chimney’s efficiency and safety. These liners are versatile and can be used with various types of furnaces.

Assessment by a Qualified Chimney Sweep Service is Vital

Determining whether your chimney needs to be relined for a new furnace installation is not a straightforward DIY task. It takes a professional assessment by certified chimney sweeps who can evaluate your current chimney’s condition, the specifications of your new furnace, and local building codes to provide a tailored recommendation.
