hey everyone,

Winter's right around the corner and after 2 years without studio
heat, I MAY finally be able to do something about it.

I have a 1,500 (30' x 50') sf studio with 17' high ceilings (Quonset
hut, so only the peek is that high)

I've been leaning towards a propane tank outside and one of those
propane-powered shop heaters mounted up on an end wall. Are these the
best way to go? any other suggestions?

One consideration is that burning *any* fuel in the shop creates
water vapor (burning the hydrogen in the fuel) as well as CO2 (from the
carbon part of the fuel).

Since you are starting out from a cold shop, the air will heat
up first, and hold more of the water vapor, and the machine tool
surfaces will take some time to catch up in temperature, so the water
vapor will condense on the metal, thus risking serious rust problems.

An electric heater keeps the air dryer, as does a heat pump.
Both will cost more to run -- but are less likely to damage your machine
tools.

You say "studio" heat -- so you may or may not have machine
tools there to be damaged.

Enjoy,
DoN.

There are several brands of direct vent pellet, NG, and propane heaters
that do not add combustion products to the inside air. They are not
cheap, but they will prevent the excess humidity build up.
