Recently we got some (natural) gas logs which work very well, but I can tell
that probably more than half the heat goes up the chimney.

I remember years ago when we had unvented gas heaters in every room. There
seemed to be no danger then.

My question is, is there any danger to plugging up the chimney, at least
partially, so that we get some of that lost heat in the room?

I believe the danger is not carbon monoxide, but oxygen depletion. This is a
very old house and drafts alone should be enough to prevent serious
depletion.

You're good at intemperate language, but you don't answer the question: How
do modern gas logs differ from the old fashioned unvented gas space heaters
that were found in millions of homes? I don't recall ever hearing of anyone
dying from inhaling noxious fumes or carbon monoxide.

You ****IN stupid idiot.
Hopefully, we will read about you in the papers, dying from inhaling
noxious fumes or carbon monoxide and NOT have to hear about your
family dying with you.
Get a gun and shoot yourself now. You are wasting valuable space on
this earth.

Please don't do that. Modern ventless heating devices are safe, but
they are especially made for that use and they have monitors to turn them
off is the O² goes too low. You will not have that.

You are right about the gas logs not being efficient heating devices.
Such is life. The best you can do is to get some good glass doors for it
and avoid much of the lost heat. Most of the lost heat is not what the logs
make, but the warm air from the room that is being pulled out.

You should have bought an insert with ceramic glass. Some are 85 percent
efficient and send the hot air into the room and the bad exhaust outside.
But considering what you bought the short answer is that you cannot use logs
intended for venting in an unvented fireplace unless you want to die. And
even though they sell vent free gas log units I would neve buy one. Code
does not allow them to be used in a bedroom. If it is not safe enuf to be
used in a bedroom I would not use it in my house.

Regarding the glass doors, if they are tempered they must be left open while
fire is on. Ceramic glass doors can be closed with fire on.

At risk of bringing down verbal lighting I also have (semi ventless) gas
logs in my old wood burner. What I did was to close the new adjustable
damper (about 8x2 " when fully open) to maintain a minimal draft but keep as
much heat in as possible.(Probably about 30% open) We used a U tube water
air flow gage , but comparing it to just a piece of tissue in the air flow
into the fireplace the tissue as a air flow indicator was almost as
effective. Setting damper in chimney and using instrument was a tough job.We
did this 4 years ago and re set the damper every fall. Worst problem is with
family of wasps that live in the brick chimney can't drive them out with the
heat the gas logs deliver. Any help available?

There are three types: vented, unvented, or direct vent

You have vented and no you cannot plug your vent source (chimney).
They are very inefficient and do not create much room heat for the
BTUs of energy they burn.

You can get unvented which will give you much more heat, but they are
bad about creating moisture making the windows and often other
surfaces sweat. And I don't believe any are rated for sleeping areas,
which should give you an indication of their relative safety.

Direct vent (have both external combustion air and a vent stack that
is internal to the combustion air pipe require a small stack that can
go straight out the wall without requiring a drafting chimney. They
put out a lot of heat but they are glassed in rather than having an
exposed open flame. You can still see the flame behind the permanent
glass door. It is the most efficient and also most expensive.

Why, on earth, do you want a fire in the middle of your living room? This is
an anachronistic vestige of man's days in a cave. You are nurturing your
atavistic genes :-)

Actually, that is where mine is: In the middle of the living room....
