Can chimney be removed?

I am considering a furnace that will vent and get air through a flue in the basement window. The current chimney which measures 25" x 40" inside the walls of the house.

My question is if the chimney is removed will a new roof need to be installed or just the piece where the chimney exists the roof? Is there an alternative solution like a sky light?

Is the chimney wood framed or brick? Is it located on an outside wall, or in the middle of a room? Not sure of the code worthiness of the venting through a window is, but I question it as only being a temporary looking set up. Will the new flue pipe have to go up through the roof? What is the efficiency rating of the new furnace?

What does the water heater vent to if it is gas operated? The window would have to be removed and covered with wood and the exterior would have to be code acceptable.

A chimney that large would typically have more than a single flue in it, serving other things like water heaters, fireplace, wood or pellet stoves, or even an incinerator if the place is old enough. Make sure nothing else is venting through the chimney if you decide to remove it.

If nothing else is using it, then yes, the chimney can be removed. I've removed several over the years, and all it takes is a lot of grunt and a place to get rid of the bricks, mortar and flue sections. Along with some interior/exterior carpentry work to close up the resulting spaces created on each floor. A 2' x 4' skylite would fit in the vacated space, with some relatively minor modifications.

This is Just My Opinion but I've done that and bought a through-wall high-efficiency furnace and water heater. I will forever regret buying these complicated cheaply-built unreliable appliances just to gain about 7% better energy efficiency. What few bucks I have saved on natural gas over the years has been spent many times over in service calls.
