My neighbor is running a simulated-fireplace that is made using
imitation logs fired by propane. The unit is UNVENTED. This thing is
in a room addition, and all windows are of course closed (it is winter
after all). Anyway, I don't see any venting provided for air intake.
I am concerned that she shouldn't use the thing since (1) with no air
venting all the room's oxygen could be used up and (2) the exhaust
won't make for good breathing either.
What do you out there think of this? Should I push the issue and tell
her not to use it? She is a recent widow and is alone and really is
quite helpless. Cripes - she even threw her car keys out in the
Depends. There are unvented propane heaters that over 99,94% efficient and
no exterior vent is needed. They also have low oxygen monitors so if the O2
is depleted, the unit shuts off. If that is the case, just go back to
minding your own business
Vented or not, a heater of that sort will have air convecting over it. The
air will carry a lot of dust, especially if there are smokers or candle
burners, and discolor the walls. Of course, if the husband dies of carbon
monoxide poisoning, you have a valid concern.
It likely has an O2 depletion sensor, but generates about 11% of the output
as water vapor, eg 1.1 pounds per hour at 10K Btu/h. A dehumidifier or an $80
window AC with a $30 humidistat that runs it indoors when the RH rises to 40
or 50% can efficiently fix that and prevent condensation on windows.
A through the wall vented heater would cost about five hundred dollars.
If the fire place is of recent manufacture it has an oxygen depletion
sensor built in. As a minimum the space should have a working Carbon

are not single, your better half can plug in a co detector for her!
more importantly, she will also thank you for telling her she is not
usually liable to repay unsecured charge cards in her spouse's primary
name even though she used the cards or the money. and that the term
life insurance is hers to keep without being taxed. and the co-owned
vehicles and home are in her name but their payments do continue.
you must verify locally with a wise older attorney. everyone needs to

personal obligations to recordkeeping and laws when you step up to
help a grief victim.
==Well then, off with her head! :-) We've heated with an unvented propane
for 10 years and I don't believe we've had one fatality. They have OD
sensors built in and recommend the use of CO detectors. Does she have one?
