Ventless Heater for Garage

I'm looking at installing a heater for my garage.  I was planning on a regular gas heater that you hang from ceiling.  However when I was at Menards I saw they had a ventless gas heater.  They are about $170 compared to about $470 (different BTU's though).  

Anybody have one?  Are there any problems with them?

 you shouldn't have any problems with them a garage isn't very tight.  But you need to get adequate btu's.  how big of a garage do you have?

 Its about 800 square feet. 

How bad are the problems with moisture from these heaters.  Some people say they put out a lot of moisture.

I have one of those from Menards and it warns my 26 X 28 insulated garage, Takes about an hour to warm it up enough to work in there then keeps it warm on lower setting. It is the second one I had in there The first one was a little smaller but it lasted about ten years. I use a carbon monoxide alarm in the garage.

 vent free puts out a fair amount of moisture.  but garages are pretty loose and you shouldn't have a problem.

Like the others said if it's not that air tight they'll be ok.  But if not moisture will eventually be a problem.  I'd spend the extra for a good vented one myself.  More btu's when you need it and no worry about moisture.

my brother switched his back to a vented one because of the moisture buildup. I put in an off- peak electric- but I already had a 220 outlet- both work good,

the best time to plant a tree was 20 years ago, the second best time is today

Don't know about a thermostat, I just turn it down after the garage is warmed up. I don't have a moisture problem because the door is not totally sealed.

 I went vented, didn't want the moisture.  I keep a 26x28 at 50 degrees all winter.  Warm it up if I am working in there.  Cost me about 20 a month.  Wife loves the warm car in the morning.  I have a detached garage with no floor drain.  I use a dehumidifier to keep the water off the floor, and it works really well.  Much easier to maintain the heat then it is to heat it up when I need it.

If it flies it dies!

 2 electric hanging. only use 1 to keep it at 50 degrees set at about 1/2 throttle with these cold temps . Extra heater is for garage party or sausage making. Ceiling fan is a must to keep heat to the f;oor.

 Yeah, I calculated my off peak electric costs about 24 cents a day for a very large garage/shop to 68 room temp..  Wall thermostat and if you already have off peak service you can pretty well install it yourself.
check into off peak service.  If U have to retrofit it might cost U some bucks, but the payback can be pretty good.

$7 a month? I  keep what I thought was a well insulated shop at 40 degrees  I average 150 gallons a year. Added solar 2 years ago and cut that  in half.

only if you pull a permit.  I wouldn't piss with that for a garage.  I don't think it's against their code in a non-living space which a garage is.  but I may be wrong on that.

 Kzzking.  Yep, the off peak is really cheap!   But you can only use it for heating.  As I understand it, every bit of power generated must be used, so they sell it really cheap, but you can only use it for heating.  So you have to have two panels, meters, 2 lines to your House ,etc.
 bUT - If you heat any living areas, you have to have a back up system, like propane or natural gas.  You don,t need that if you heat a garage or shop.The electric company reserves the right to cut off the off peak power when there is high demands, so possibly the The heat to your garage or Shop, like mine, could have the heat cut off during high demands.
we have only lived in our house for a year or so and I don't think the off peak has shut off yet, but as a computer automatically switches from off peak to nat gas when the off peak gets cut off, I can't swear by it.  The computer automatically switches to the cheapest power source st that moment.  If you have no backup he at source for your garage or shop and off peak shuts off, you are out of luck till it goes back on. Still if it's only a garage pr shop, it'll likely go a few days before freezing.
seems to be a good system, so far.

you can use it for a/c and water heater also.

you can use off peak for water heater, and a/c or heat pump. Your electric provider can only control you for 20 minutes per hour. You would never even notice.
I am on VEC near Minot. Regular electric rate is $.093 per Kw. Off peak is at $.044 per Kw

 What power companies are you with that only control for 20 minutes? We have Ottertail and it is longer than that. Still worth it for the rate. Mainly a problem for using the clothes dryer.

The former owner of my place has a Natural gas pipe outside the garage wall to use NG for heat.  Does using NG require inspection / permit?  This is in stark county.  Who do you contact for the info / permit?

If you pipe it into your house you do.  There cannot be any joints that are hidden under sheetrock, etc.  Unless it is black pipe, joints are welded and pipe is pressure tested.  Best to use the flex pipe in one piece to the appliance if you can.  But if you tap into a pipe outside and keep the pipe outside and jump it into your garage with one piece of pipe I don't think you need a permit to install a garage heater.  But that can vary from city to city.  I don't think any counties will require one.

It is wired in with the water heater I believe. Ottertail controls all three seperate or the furnace and the other 2 together. I never notice the water heater as we never have cold water. With the dryer they have to be wired so the fan is not controled. A concern with it stopped with a hot element or something. So what happens is you have to run the dryer  to determine if it is heating or not. I should wire in an indicater light off of one leg.

 Brain fart. The water heater and dryer are controlled together. I am signed out for email notifications of when they are controlling I get 2 sets.

it depends on which electrical company your using.  Mountrail/Williams doesn't allow the dryer to be hooked up

I put in a NG oven/ stove in the kitchen for the wife. Ran the flex hose from one side of the basement to the other end and up through the floor under where to stove would be. Blead the line out, pressure tested it and called it good. This is in your same county.
If I sell my house it might then need to be inspected, however I havent any plans to do so for now.
If you have a paid pro do it, you will have to have it inspected.
