I want to have my basement set up to go to if major winter weather strikes LONG Term and no gas, electric. My heater no longer uses the chimney only the hot water heater. I would like to put something like a oven hood attached to the old heater vent to vent out smoke, can anyone see a problem with this idea??? I am trying to do this as cheap as I can and not leave it in place.

Yes, burning your house down would be an issue with using an oven hood to vent a woodstove.
There is a huge difference in heat values between a regular oven and a woodstove.
I'm also unclear, would you have an open pipe that would release up into a hood? that's a double whammy there if so.

disidoro I would be using a small backpacking foldup stove or charcoal on a dutch oven. I would make a large hood that would attach to the chimney. I wanted to know if the smoke will vent up it. Will there be any other problems?

Mixing the flue gasses is a terrible idea. You'll create a chemical reaction in the chimney that can cause damage to the structure or yourself.

It sounds like you are asking about an emergency situation in which case you probably wouldn't have the water heater running. In that scenario I would have some extra vent tube and elbows available to construct something to go in the existing (or enlarged) hole. I wouldn't recommend installing anything before you need it, because realistically you'll probably never use it. It could also end up flooding your basement with carbon monoxide.

There's a reason stove hoods have vents. They won't draft on their own.

Wood stoves require a flue that can be cleaned yearly or you will have a chimney fire. It is not a matter of if but when. Burning hardwoods just slows the process down. For a chimney located in the center of the house you need triple wall flue pipe or masonry with flue tiles. If you burn coal in your stove you can use your furnace flue though.

people die every year from just using a charcoal grill in the house.Iwould think a wood heater and a vent hood a sure fire disaster. A vent hood would also draw the available oxygen out also.

You do NOT want to experience a flue fire. Just trust me, on this one. It happened to a friend of mine, who was restoring a Victorian house. She said the whole house shook like a jet plane was taking off.......and it belched out smoke everywhere. Plus, the fire temp gets extremely hot, too.

Not only is it very scarey....but, as others have already said, it can burn your house down. It's so instantaneous that you wouldn't have a bat's chance of putting the fire out.

These work in less than 30 seconds.

Buy a small used wood burning stove and pay a professional to install it with it's own flue exiting you're house. If the stove has good dampening controls you can possibly get your money back by heating your house during winters with wood.

We cook on our wood stove and in our basement fireplace. You need one or the other. If you use a grill it must be outside.
You could use a propane camp stove with hood as long as you had a vent fan to exhaust the fumes out. Kingfish

single wall flue pipe needs to be 18" from anything flameable. almost everything is flameable. Exhaust hood USUALLY require some sort of fan to exhaust properly which means you need outside air to MAKEUP the difference in barometric pressure- you'll put your house in a negative pressure, it will backdraft and suck outside air in from every door and window.

If you have a suitable sized chimney why don't you just get a barrel and a barrel stove kit and make something semi safe!
technically the only reason you cant mix fuels in a chimney is a national code, lots of equiptment that have a UL rating do run Multifuels(Yukon Furnaces is one H.S.Tarn is another) up a standard flue pipe.They just dont run two fuels at the same time. if your tieing two flues together they need to increase by 2" at the tee of the bigger of the two( 8"+6" needs a 10" tee and on out )
you need triple wall for anything less than 18" clearance. Metalbestos is one brand thats good, metalfab is another.
YOUR IN A BASEMENT SO YOU NEED A CO DETECTOR ON EVERY FLOOR.
People die every day somewhere from CO poisoning.
And you need a lot of fire extingushers everwhere.
Since it's SHTF there's no codes anymore- just think things out first.
