Maybe, but then you'll be using a lot more energy overall to heat

In the "how to heat a two stall garage" thread, someone mentioned
that

a

kerosene heater would cause a lot of moisture in the garage. How
much
moisture will there be? Could I just use a low-cost (normal store

bought)

de-humidifier to make it normal humidity?

Thanks.



Like any heating device if a kerosene heater is operated and
maintained
properly there is no problem using it inside for long periods of time.
A dehumidifier would certainly add cost but, depending on the brand
and
etc., could be effective.

Just guessing but I imagine the amount of water to be removed won't be
more than the amount of kerosene supplied (recombining the hydrogen in
the kerosene with oxygen??). Maybe someone who understands the
chemistry involved can tell us for sure.

I am going to just use the heater for a little while, evaluate and go
from
there. Thanks for the advice.

I think the kerosene combines with the oxygen in the air to some
ratio,
and
that is where it gets some of the water creation during burning.
Either
way, I need to see just how much moisture is going to be produce
before
and
if I decide to get a dehumidifier.

Thanks.



Go ahead, just remember, you were warned. If you open a window or do
something
else to introduce oxygen, you will not experience oxygen depletion.
That's
fine
for normal people, but you have a shop full of ferrous objects. When you
burn
any hydrocarbon, the basic reaction is that the byproduct is water
vapor.
In a
shop, you HAVE to vent the kerosene exhaust completely or your machines
will
rust quickly.

You have been given some marginal advice. The guy who dumped the MSDS
didn't
realize that your concern isn't only safety for humans, it's also
preventing
rust to your machines. Water vapor in say a bedroom is a good thing.
Often
in
winter the air is very dry and adding some humidity makes it feel
warmer.
That's
why you see those cast iron kettles on wood stoves, just to add steam to
the
air. Yes, it's safe to use a clean well adjusted kerosene heater inside,
but IT
WILL RUST YOUR MACHINES.

I would never ever trust a dehumidifier. Not for one millisecond. Trust
a
chimney.

Actually, the largest machine currently in my garage is a 6" bench
grinder.
I usually keep it in a drawer when I am not using it.

I bought a carbon monoxide detector with a level gauge and a
thermometer/hygrometer (humidity level). I am going to check various
situations and see what works best.

Thank you for the suggestions.


Here is a follow up. I found a combination I am happy with. Keeping the
attic's fold - up ladder/door open allows the garage to get "warm enough"
(60 degrees) with apparently enough ventialtion. It was 30 degrees outside.
It's only a little stinky and a lot warmer. Humidity is greater, but maybe
by 10% or so. I think the cold, dry air form outside rushing in causes
this. When the heater is run when it is rainging outside, humidity from
outside coming in is far worse than what is caused by the heater. The CO
detector has a "highest level recorded" memory setting. It is still on
zero.

Just for testing purposes, I ran the heater with no ventialation for a while
and it gave me a headache. When I ran it with the attic door open, I got no
headache.

I suggest getting a hygrometer if moisture is a concern.

Thanks.
