Chimney Lining

jim lockard

What is the current condition of your chimney? Is it brick or block? Is there a clay liner in it now? what is the condition of that liner is it of proper size for the load? What type of fuel has been exhausted up the chimney? Jeff Just because the chimney is in the center of the home and some what protected does not mean its safe. I would suggest you contact a good chimney sweep. Get you chimney checked and consider having a properly sized liner pulled down it. Look at the top of your chimney we call it the crown if the bricks are spliting or leaning or just look nasty your chimney needs help. Go up in the attic if the mortor joints are black or loose if the bricks are cracked or loose again you need help. Best Wishes J.Lockard

I'm considering replacing my old steam boiler and am working with a company in preparation for the swap from old to new. When I asked the contractor if I needed a chimney liner he indicated that the chimney that services the boiler and hot water tank runs inside the house and therefore, does not need a liner.

Does this sound like sound advise?

unless you have a metal liner, you need one

oil or gas? If gas, you can use steel, aluminum or stainless, (at least around here). one of the byproducts of combustion is acidic and will destroy the clay linner or brick and mortor

guess you better check with the bldg insp

around here we are required to line, but as the previous post suggests, that is not required everywhere

If it was a brand new chimney I would line it. Maybe run pvc down it for the condensing boiler/ furnace. J.Lockard

The chimney is all cinderblock except for the brick portion above the roof line. I can see the chimney from the attic and garage and there are no black spots. The boiler burns natural gas but was converted from oil many years ago. From the outside, the visual apperance of the brick portion looks healthy (from 30 feet below), no leaning, falling brick, etc.

Without a tile liner

I would certainly line it. Condensation is much more likely with the new boiler and will destroy the unlined chimney rather quickly.

Level II inspection & liner

You need a level II inspection first. Then that will help in choosing the proper liner. The presence of flue tiles or not is a joke. Terra cotta flue tiles are:
fragile and don't hold up
usually oversized
a massive heat sink
have lousy or missing mortar joints every 2 feet.

Even with a brand new chimney that meets the code, which you'll never find, you'd probably need the liner for sizing if nothing else. Interior chimneys perform better than cold exterior chimneys but that is not the basis for liners.
