A friend of mine got a Sears furnace, a small one that fits between
two studs, to heat his garage. It runs on propane.

So he wouldn't have to keep changing tanks, another friend gave him a
propane tank that is twice or more the size of the tanks that go under
propane grills. This is the size that is used to fuel fork lifts.

But now he is told that that tank is for *liquid* propane, and he
can't use it for his furnace.

I thought that unless the pressure is higher in the big tank than the
little, either both tanks hold mostly liquid, or both hold only gas.

And regardless, that what comes out when you open the valve is gas.

Why shouldn't he be able to use the bigger tank for his furnace?

The tanks on the fork lifts are different but only in that the wall of the tank
is thicker and will take a hit by a large object falling on it and not smash it.
you can take a BBQ grill tank and hit it with some forks of a lift and knock a
hole in them. The fork lift type tank can be hit by the forks of the lift and
just bend in and not knock a hole in it. If having a heavier duty tank on it
mean to not use it , well OK.

Also both tanks are fine but never use a propane tank upside down for you do not
want liquid flowing to the valve where it goes to the appliance or furnace and
equipment is designed to run on vapor and not liquid. A propane tank is full
when it is about 1/2 full and no more. It has 1/2 vapor and 1/2 liquid in it.
Now they do put a rock feeder in them for people who likes to put the tanks
upside down on the furnace or appliance and will feed it to not let the liquid
through and just let vapor through.

Give me a Fork Lift tank anyday before getting a BBQ grill tank for they will
take a beating that a BBQ tank will not take.
