I would like to be able ot heat my garage and keep it at a good temperature for a few days at a time





I would like to keeo the garage warm enough to have the body on the car heat up enough to detail it, as well as have a comfortable working area.



Dont think it is safe to leave propane heaters on while I am not around keeping an eye on it, etc and electric is probally way to expensive.



Any other ways to do this?
 
Our master bedroom and bathroom reside above our garage. They used to get quite cold in the winter as the garage was unheated. My local utility company sells and installs radiant, ventless gas heaters. After installing this, we keep the garage at about 50 degrees during the winter. When I need to work in the garage, I can crank the heat up to over 70 degrees if needed. I am a big fan of this type of heater and will likely incorporate it into my next house.
 
My garage is detached so it gets quite cold. (or hot) I installed a full fledged, residential gas furnace-a/c in the attic of the garage. It was a lot cheaper than you would imagine and is extremely efficient to run.



I also keep the temp at about 48° during the winter and crank it up when I want to do something out there. It takes about 15 minutes to hit 65°.

Also..my garage is attached to my house. How can I just connect my heating/ac systems from my house to the garage...but on a seperate system so they dont have to be the same Temp.



The cheaper way would obviouslly be nice.

I have about a grand wrapped up in the furnace, a/c, ducts, cold air return, and wall insulation, thermostst, etc. You can do it for much less depending on the btu's required for the square footage of the space.

Roughly how much am I looking at to live in your garage, per month? 48 is fine with me, I have tons of fleece.
 
I use a propane ...blower type heater & crack my windows about six inches while I'm detailing. My garage is a two car and it heats up quickly....when it reaches 60 degrees ( about an hour) I turn off the propane & shut the windows....If and when it gets below 40.....about 3 hrs later I repeat the process. Thank God I live in North Carolina. I lived in North Ohio my whole life & know what you Northerners endure.....
 
Part of my garage was built in 1917. (It was a carriage house) I added the new part a few years ago. I put in glass block windows for security and insulation properties. They work well. As you mention, insulation is a must. I did the entire attic and the walls of the new side. The old side has brick on both sides of a concrete block center and is over 14" thick. It insulates well. Insulate your garage door, too. I was amazed at what a difference that made!
 
I am in the process of building a new house and am having the garage insulated. I will be installing a natural gas ventless heater in the garage. My builder has one in his and keeps his garage at about 70 degrees. I wont keep mine that warm except when I want to work out there in the winter.. The unit can be bought at Lowes and cost less than $300. I am buying a 30,000 BTU unit.

Hope this helps.

I just went to Menards and bought a oil filled NOT oil fired heater and it workd fine for getting the chill out of the air. I usually turn the heater on about an hour before I go to the garage and it will eventually bring the temp up to 60 degrees. It has its limits but for $30 and as little as I use it, its fine for me. I have a new house 2 stall garage and it is well insulated with only the garage door and half one other wall exposed to the outside.



Now if you really want to heat something up get a Reznor. They are cheaper than a forced air system and they work well they are even cheaper if you happen to have a contractors discount. My father has one and in 5 to 10 min it can bring the temp in his large 3 stall garage from 45 to 65-70 degrees.

If I were to build or update a garage, I would insulate it out the wazoo. That way it wouldn't cost as much to heat with some kind of portable heater.



Double paned glass, foam sheeting and fiberglass insulation like no one's business.... some kind of insulated garage door or maybe insulation added on to it. Sure, the walls would be 1 foot thick, but hey.... :D
 
I use an 18,000 BTU vent-free propane heater for my 2.5 car garage. It was about 0 degrees the other night. I had it up to 60 degrees. This past summer I insulated the ceiling and walls. I had the same heater before the insulation. Insulation made the biggest difference. It also helped to fill in the cavities(with the insulation) between the rafters so the ceiling was flat, not bare rafters. I have been trying to keep the door closed. The heat from the cars seems to stay in better too.
 
how long does it take for the surface to warm up enough?



If I can get something that is cheap...will warm the paint of the cars up enough in an non insulated garage i am set.
 
My garage is just drywall on the inside..brick on the outside. the garage/house is 30yrs old.



To heat it up to the proper temperature to detail it in, be warm to work on it it will take a few hours on a how many BTU heater?



thanks guys. and is it safe to leave un attended for a few hours while it is heating up?
 
I would say a couple hours and you'll be fine. You really don't need it to be t-shirt warm to detail. .Fresh air is very important! The fire will suck all the oxygen out as well as produce carbon monoxide(or is it dioxide?)
