    I bought a dehumidifier for my shop and the first night I used it I filled a 5 gallon bucket with water, I was shocked because the shop is insulated and sheet rocked. You can mount it out of the way and run your drain line thru the wall to the outside. No more moisture on anything after I installed this. A good one will run about $200.00

    Yeah, the heat and cold cycles will cause this pretty readily. If round the clock heating isn't an option, like said above, a dehumidifier is your friend. You can buy a cheap temp gauge to hang on the wall, get one with the humidity reading too. You will see a difference in a short time with the dehumidifier.
  5. Lots of good info here. Might I suggest you check out a TON of info over there! Well worth joining. I have a 20x20 attached garage. I am planning on insulating and sheet rocking te whole thing this spring. I've done a bunch of research and for me I am going with a Dayton G73 220v electric heater. Todd

    The absolute best way to heat your garage is with a radiant tube heater. I have a 10' long natural gas unit in my 24x26 garage and it keeps it toasty warm and is really affordable to run.

    Alberta winters are much more bearable with a warm garage.

    Might look around for a regular forced air gas furnace used in homes. I have about an 1800 sq. ft. shop and I used a 250,000BTU upright gas furnace, all ducted & stuff to put the heat right where you need it, just like a house. It was easy to install and has a regular house thermostat. Keeps me nice & cozy even in some pretty cold Colorado winters. Many folks around here get rid of good, but less efficient models to upgrade to a more efficient one, but the lesser ones are plenty enough for a shop where you are not running it full time.
  8. I have two of the "hen house" 220 volt heaters ... small, easy to handle, have one hanging from the ceiling and, if needed I place the second one on the floor.

    Attached two car garage (Southern Ontario Canada). Only run them when I'm going to be out there ... my car sat in my garage for 5 1/2 years with no paint (none ... no primer either) on it and it did not rust at all. My house is all brick and there is a door from the house to the garage. My guess is that there is enough heat loss through the (one attached) wall that condensation does not form. Garage is fully insulated and drywalled (except for the wall attached to the house).

    Electric heat is the best for me ... no noxious/dangerous fumes and no tanks to fill.

    Bought one heater from the farm Co-op for $99 years ago and bought the second from Home Depot for something like $69 or $79.

    My shop is 24x30x10, the walls are insulated but not the ceiling. Got a free standing woodstove with a blower and a ceiling fan. I burn everyday in the fall and winter, burn ban or not. It's a living space to me so it's a labor of love.

    I'm replacing the overhead Modine heater in my car shop right now and replacing it with a Dayton radiant tube heater. With the Modine heater the upper 1/2 of the shop was warm, the tools were cold, and sometime there would be ice under the car when you worked on them. With the tube heater, it heat objects not air, so tool are warm, the floor is warm and they run for about 1/2 the cost. I will have about $1400 installed (My labor ). I am looking forward to getting some real heat in the shop, I have heated my business building for 12 years with radiant heat and love it.

    i think i might have to try the radiant tubes. i have a 40x60x12 shop that is currently heated with radiant in the concrete floors, and i use about 300 gallons in 6 weeks. i simply can't do that monetarily, so i need a new solution. i just want it to be 50-55 degrees in there, so i'm not asking much...

    Check into buying a older mobil home propane furnace, I installed one for less than $200.00. It stands on floor with min. room, 30" x 30" x 80" tall.
    Bought furnance for $60.00 and with new roof vent pipe and drilled out the orfice to convert to natural gas and brought Natural Gas line in from house with the yellow flex pipe.
    Love it ,has fan mode for summer and it vents to the bottom so the fan blows across the floor. No duct work required.!!!
    Turn it on when working in the 2 car garage and turn off when gone.

    Get a propane trailer house furnace. They blow heat out the bottom. Set it up about 18 inches off the floor on a 2X4 frame and put a curved piece of sheet metal from the floor to the furnace to direct the heat out into the room. You can work under a car and the floor is warm. Just my 2 cents worth.

    I guess I should have read the last post before I posted.

    It's a little off topic but.......

    I make my living as a self employed plumber. I have installed a lot of radiant floor heating systems for small garages that run off of a small boiler or a 40 gallon water heater. Obviously the heat system is in the concrete so for many that's not an option. BUT......a few jobs over the years were car guys who busted out old concrete, installed the heat coils.....and re-poured the concrete.

    It's not the cheapest option but it can be done rather affordable if you know a concrete finisher or feel confident in your abilities. The heat system itself is pretty cheap on a small garage because it's only one zone. A water heater will heat a 24' x 24' garage footprint extremely well.

    Something to think about anyhow. I wish I had it in my garage because it's the best form of heat. Nothing beats a warm floor. I'm just not in the mood to bust out concrete and deal with the mess but i'm tempted. The guys I know that have done it are very glad they did. It all depends on your person budget though.

    hdman has only propane

    olscrounger your unit works great in CA but he's in Mn the winter temps are too cold to work efficently but the ac in summer is great. I have what hdman has only propane (I wish I had natural gas) my bldg is 40 x 60 with 14' walls and insulated. I keep it on 42 degrees when not working and turn it up to whatever I want when in there. The heat the objects in the bldg. I have gone around with a infra red thermometer and check the floor and its whatever the thermostat is on. Propane is pricey so if NG is available thats the ticket. I didn't know they made a oil fueled one. Do not use a unvented heater your life will depend on it.

    I have a bottom drop mobile home furnace in my 30X36 10 foot side wall shop. It runs on propane my shop is well insulated with good windows and doors. I use about 325 gallons of propane a year. I use my shop almost everyday. I paid $350.00 for my heater from a mobile home dealer. I live in NW Minnesota so I understand the cold. good luck
  27. I am using two 7000 watt ceiling mounted heaters in my older garage, and they have worked very well for me. I live on the wet coast, so they don't get much of a work out in this mild winter climate.
    For my new 2000 sq ft two story garage, I am using in floor hot water heating, and have a 70,000 BTU electric forced air furnace to supplement this set up if I need to warm the garage quickly. The garage will be well insulated.

    I have a 75,000 btu Hot Dawg gas heater for my 3 car garage. I don't use it very often so I can't tell you how much it costs to operate. Hope you find something you like and is affordable.

    Over the years, I have tried a lot of different ways to heat my two car garage. I broke down and bought a small house furnace powered by gas, Yes it cost a lot had to run a gas line out to the garage. But in the end it was worth it.
    If I would have done this in the start I would have saved money.....Good luck Mike
