Hi. I have a sunroom in my house that's heated on its own separate
furnace, which is likely about 20 years old but has been used only
sporadically and appears to be in good condition. I'm removing the
sunroom, and was thinking about converting the furnace to lp gas and
setting it up in my garage. The garage is difficult to get a gas line
into, plus I'm installing a gas fireplace and am just about maxed out
on how many gas appliances I have already. I don't need the garage
heated all that often, but would sure like to be able to fire up a
furnace when I need to.
Is it easy to convert the furnace to propane? and is it worth it?
Thanks for your help.
cvall the furnace manufacturer and see if the parts are available. with
a 20 year old furnace it might be a problem.
have you priced propane and tanks to run a furnace? I would run a
natural gas line or use a portable LP bullet heater for occasional use
At that age changing out the orifices would be very difficult even if
it were ever possible. I doubt it's worth it.
I'd get one of these which'd be a lot more flexible and compact:
Thanks for the advice, both posters.
I was wondering if it was possible, only because I don't want to throw
away a perfectly good furnace, and I know this thing is probably only
worth $100. I didn't want to use a space heater, because I will only
use it occasionally, but when I do, I'd like to be able to heat it
Tank price isn't a problem, I have a couple of portable tanks I can
use, and shouldn't have to refill all that often if I'm not using it
often (probably only about once a week, for 6-8 hours.)
I'll check with the manufacturer to see if I can get parts, in any
Thanks, I'll let you know how it works out.
To get a idea look at the size of the supply line to your furnace, they
use a LOT of gas..
Too small tanks wouldnt be able to supply enough BTUs to get the heat
exchanger hot enough for good heat transfer and worse you will empty
those tanks fast:(
Had a friend with a serious house fire in winter, utilities cut off for
Bought a nice big bullet heater so we could work. didnt do much with
those 20 pund tanks.
ended up buying a small bullet heater to spot heat one room at a time
Well, I'm getting the sense that I can't talk myself into this! I'll
look into the cost of bringing in a gas line, or else take your advice
on a new propane heater. Thanks for your help (and likely saving me a
pile of dough!)
