I have used a space heater for my shop (10'x16'), however it isn't the best option.  Towards the end of the year we are going to put an addition on, and I will have a more permanent solution for heating and cooling.  In the meantime, I was thinking about using an electric stove/fireplace.  Any thoughts on if this would be good/safe or has anybody used to heat their shop.

There are some nice through wall high efficiency units available. I would prefer to use a dedicated, listed appliance for an attached shop. The potential fire hazards would make me leery of using some makeshift set-up for something attached to the house. You could also end up in trouble with your insurance provider if there is a problem.
That's not to say I haven't used various propane and electrical heaters over the years. I haven't had issues but know other people who have.
Since you are looking at an addition and more permanent solution by the end of the year, I would just stick with the electric space heater. It's almost March now, you only need to use it for a couple more months really. I'd save the expenditure.

I use a Williams Direct Vent furnace fired with propane. The unit is complete and fits nicely into one stud bay. Easily installed and does not draw air from the shop which cuts down on the chance of dust explosion or any such fire hazards. It is very, very efficient and my unit is 32,000 BTU's (I think, maybe it's 50K) but it heats my 26 X 32' shop (about the same size as a two car garage) with ease. I really only turn it on when I go out to work and within minutes the shop is toasty.

I thought about a wood stove but floor space in the shop is a  premium commodity and the risk of  fire is very worrisome. The unit runs about $1200.00 and comes complete (UPS) with the duct work, thermostat and everything you need to install directly through an outside wall. You can go on line and Google Williams Direct Vent Furnaces if you are interested in more information.

Pretty slick unit especially for a shop environment  IMHO. I know a lot of people select this type of heater for their garages or similar spaces that need occasional heat.

 The unit I am looking at retails for around $100.

Unless that is a 240 volt heater, I doubt an electric heater that retails for 100.00 will work too well for you. Well it might work if the current cold snap in the north east eases up.
You have 1280 square feet to heat and if it's uninsulated you'll need at least 30K BTU/hr or 8507 Watts to maintain a temperature of 60F.

I installed radiant heat in the concrete under my shop floor and heat it with a boiler in a separate building with this in mind so I have less concerns with the heat system than most.

Mike:
I like radiant heat too, and think it's the best solution for a shop (no blowing dust around with forced air etc.) but what do you do for cooling?

Tim, currently I use a thru the wall a/c unit and that works fine 95% of the summer. I am currently drawing up a central air system that will also work as a larger ambient air cleaner, all year round.
I don't use the a/c for cooling as much as humidity control, but it keeps it around 70 in the shop on the hottest days.

Wooden Skye,

Check out the Enerjoy electric radiant panels @ http://www.sshcinc.com/woodshopseries.htm.

I used a single 2' by 8' panel in one 14' by 14' room in my last shop in PA and it would absolutely cook you. Mounted flat against an 8' drywall ceiling w/ 4 screws, only 1"+ thick.

I am insulating/finishing my little 10' X 12' shop now and will probably go with a single 2' by 4' panel this time, last I checked they were around $200. On 110V it draws 500 watts/4.1A for 1,700 btu and you can use a cheap line-voltage t-stat. I find with radiant heat, in a sealed space, I am very comfortable working at around 50 degrees.

Tim, my space is only 160 square feet, but part of it is unusable space, for the part where my MFT and lathe are, I think the unit I am looking at should work. 

Sorry, I should have written you have 1280 cubic feet (10 x 16 x including the height of your walls if they are 8 feet. That's much different than 1280 square feet.

I always trying to avoid direct flame, or open spiral heating elements. Do you have city natural gas pipeline in your town? In my opinion it would be most safe and economical source of heat.
