Whats is the big deal, I have used both propane and kerosene heaters for
the
shop from time to time. The propane puts ALOT of water into the air. The
kerosene heater puts almost none, in the winter I could run the
dehumidifier
for a month with the kero heater running and NEVER fill the tank. I will
say
that the kero heater ONCE running makes far less fumes than the propane
heater I have. ( the propane is 2 years old the kero is about 15 years old
with a wick from way back when) I don't even use the new heater, and to
top
it off propane costs more per BTU. You need to be very careful with any
space heater, but if used correctly they are safe.

Thank you for sharing your experiences.

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.
