I recently installed a new hot water heater and heating system in my home. Both systems use a direct vent to outside. The old systems used the chimney to vent to the roof. I also know the chimney is not structural to the house. My question is can I remove the chimney from the top down? To gain space in my home which would expand size of 2 bathrooms. Does anyone see any problems in removing or having a home without a chimney.

Thanks Shaun

If the chimney isn’t structural, I see no issue with removing it. Fireplaces are inefficient and polluting, and if someone decides they want to put in a pellet stove or similar later they can always run some of the modern multi-wall duct stuff (that I’m not clear on the particulars of because I’m moving further and further away from anything combusting in the living area).

Remove it if you choose. In some parts of the country it might lessen the value of the home but these days there are so amny options out there that people don’t mind. An alternative fuel is not a bad idea but like mentioned if you have a regualr fireplace they just draft the hot air out of the house. If I had gas I would have ventless gas logs in my house…but that is just me and I don’t have gas available. Be careful and be safe with this challenge.

It shouldn’t be structural, and leaving it in just presents a huge cold sink for the house. It serves no functional purpose at this point just another point at which your roof can leak.

Take a close look at the chimney. I have a building that was recently re-roofed with new deck and architectural shingles. Here is the point. When the roof deck was taken off I got up and looked at the structure. The chimney was cut back where the roof and chimney interface and was actually used as a structural support for the chimney, probably during construction, as well the chimney was used as a structural support for the roof joist. At least in this case I would be reluctant to remove the chimney as the span between supports for the roof would be dramatically increased without the chimney.
