My workshop is our 2 car garage. Any suggestions on a good heater?
I have a 220 outlet but when I look around the heaters I look at say 240v.
Where?I fill my cylinders locally, getting the full 20# for $10 which includes tax.
Don't like gas in the shop, it adds humidity.
[/QUOTE Can you prove your claim? Humidity from heater helps to off set the dry air from outside. Never in 15 years has anything in my shop rusted because of humidity from gas heater. Check out post in hot deals about Northen clearance sale on Mr Heater wall mounted gas heater.
OK about methane, but what about propane? Assuming an air change at least twice a day, how many pounds of water would it take for the air in your shop hold just to maintain 45 - 50% relative humidity? A 20# cylinder lasts on average one week. (168 hours) Divide 20# by 168, and you get approx 0.12# of propane per hour. Multiplying that by two, you get about 1/4 # of water per hour. Multiplying that by 24, you get about 6 # of water per day. The drier air entering your shop will quickly absorb this.What should I prove?
We know in chemistry that one molecule of methane burned, produces two molecules of water vapor, or one pound of methane burned produces 2.25 lbs of water vapor.
Without doing the calculations RH in Raleigh is on average 85% in the morning and 52% in the afternoon. If it rains 100%. If you are running a gas heater because it is cold, are you pulling fresh air in all the time, or are the windows and doors closed while the heater is blowing carbon dioxide and water vapor into the shop?OK about methane, but what about propane?

First of November, set heater to hold shop at 58 degrees, 24/7. I found it more comfortable to just set heat, rather than trying to bring it up when I work in there. Dog (14 YO) sleeps in shop on cold nights (below 45,) and I store a couple hundred pounds of sweet potatoes in there. Sweet potatoes don't keep when stored below 55 degrees. As for relative humidity levels, that's not during the colder months. When RH is 100% at 33 degrees, what does that make it when air is raised to 58 degrees?Without doing the calculations RH in Raleigh is on average 85% in the morning and 52% in the afternoon.

Burning 1 lb Buthane produces 3lbs of CO2 and 1.5lbs of water. If it is raining for a long period and you have a gas heater running in the shop, once you turn everything off, shut the doors and everything cools down, the shop temperature has to drop below dew point. Sorry I did not look up propane.
My new shop is fully AC, which is why I offered the heater to the OP free. My old shop was not conditioned and I used a gas heater a few times. Had to clean up all my machine table tops and keep them waxed after that. Problems with rust. Whatever works for you, I have no gas on my new property, use to love cooking with it until I tried an induction stove top, never looked back.First of November, set heater to hold shop at 58 degrees, 24/7.
