chimney questions ?

PostBy: mourning4them On: Sun Dec 01, 2013 12:38 pm

i have to say i know nothing of chimneys , in fact boilers are still new to me and i have been learning as quickly as possible, but chimneys are where i am at today. my house built in 1888 has 3 coal burning fireplaces in it but i am unsure if my chimneys are safe to work with , i have 2 chimneys with a total of 9 flues , a quick side question " my old coal boiler which is now gas vents out the chimney , does it need to be swept it has been gas for decades so my assumption is with gas heat the chimney doesn't require sweeping?. ok back to my main question how to tell if the chimney is safe , i have put my camera up the chimney i can see day light and there chimney looks dirty but nut crusty or anything like that. " i'll post pictures " my other question that some one may be able to answer is about the cast iron lining of the fireplace , is it still safe if the lining has cracked , it is original and very pretty to look at but i found where it has split , ok final question i have been thinking about gas fireplaces " gas coals they look really nice just like gas logs but with coal " is any one well versed in gas fireplaces , some say use non vented but i gather my fireplaces wouldnt meet code for that and would vented be safe with my chimneys , ugh ! ill post pics of the chimney and firepalces thanks all

Very nice! Many of the older homes only had brick chimneys, no liners. Ours is 1890 and had only 1 chimney, I believe they had parlor stove(s) hooked to it, wood or coal, not sure. since there are no fireplaces, but the round connections are in the wall/chimney for it.

Most of the older chimneys probably can be used if you have a good draft, which you probably do. Typically with the gas type fireplace inserts, they run 2 pipes, inlet air and exhaust all the way out.

If the mortar looks good up the chimney and is not cracked too much, you can possibly burn coal in it. I've been using our chimney (no liner) for 8 years now (house built in 1890) and it works great. just have to clean out the bottom with the ash that falls down. you only have fly ash as a by product, which is not flammable (unlike creasote from wood burning).

Good luck.

In unlined chimneys wood is not great because of its creosote potential as well as the large amount of sparks sent up a stack w/ a wood fire. What those fireplaces were designed for, and what they will work best (and safest) with, is lump coal. Look for lump bituminous coal (baseball size and larger) call around, check the phonebook, craigslist etc. in your area and see what you can find. I wouldn't have any problems using those unlined chimneys with coal if they were in my house as long as they were visibly sound.

Morning4them, from your picture your flu looks great. Wouldn't worry about the crack. I wouldn't ruin your fireplace with anything gas. Original coal basket and bit. coal. Here's one of my fireplaces. Over my dead body will they ever see gas. Welcome and sounds like you have a nice house. Matt
