i have 1000ft sq workshop need to get it warmer!
temp is about 0-5 at the moment!
ive been using fan heaters and oil filled rads for a while, but they are so expensive to run.
any suggestions?

Propane has worked well for us, with the tank outside, and the heater installed into the wall. I’ve also gotten away with space heaters in a pinch. Infrared “heat lamps” in regular fixtures works, too, but only if you need to raise the temp a few degrees.
I agree, though with a lot of foam dust or chemical fumes about, I'd opt for something without an open flame. . A cloud of flammable dust can make just as big a bang as a cloud of chemical vapor.
Something like this would work, for instance: http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200307957_200307957
a US source, but I'd imagine something similar is available in the UK. Smaller version here: http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200395499_200395499
As it happens, I'm putting a new heating boiler in my house this month, so the calculations come pretty quickly to mind. What have you got for wall area, roof/ceiling area and insulation?
hope that's of use

are these propane heaters like space heaters
and you just turn them off when the resin is out?
Pretty much - rubber line from tank to heater rather than, say, copper permanently set in. .
I'd turn them off when using resin, solvents or shaping if there's gonna be a lot of dust in the air. Clouds of dust...well, they can make a helluva bang, flour mills used to blow up regularly. http://www.wired.com/wiredscience/2008/03/the-explosive-t/ has more.
Now, I dunno if a 4000 BTU heater would take a 1000 square foot workshop from 5 degrees to, say, 25, but it'd take the chill off, definitely.
hope that's of use

…do not work for such volume…
I have AC s and barely work to heat ALL the room when is really cold
prepare to spend $ to warm all the glass area
My uncles in North Dakota always heated their shops with wood burning stoves in the winter - double barrel with a fan. Most of them I recall being much larger than 1000sq.ft. as they'd have a tractor, forklift, a couple cars, industrial steel shears, saws, presses etc. and a few guys working in there. Why not, the fuel is relatively free and everywhere.
I've got a greenhouse attached to my shop, and on a mildly or full sun day I just open the door and get plenty of heat. That's how I survived the weeks of freezing temperatures here lately. There are also plenty of other home-built solar options available out there.
Start with insulation - if you haven’t. See that little heater pointed at my glue (Don’t freak, just for a few minutes to get it nice a warm.), it takes it from @ 40 F. out side to this…
Don’t know why some are posting so big, and the other not… better than before anyway.
In case it isn’t clear, I put up that Johns Manville it all the walls, and 1" 1lb. panels on the ceiling… unfortunately, or lazily, I didn’t climb underneath to do the floor…
It was alot easier to air condition a shop or shaping room on Maui than it is to safely heat the same in the Pac. Northwest. My conclusion is that no matter the fuel the heat source has to be placed outside the room you are attempting to heat and work in. And yes only bring out the resin after you have heated the room and shut down your heater. I think the safest way to do this is to duct in the heat to your room from outside.
Feeling your pain at the moment pete, I’ve been making a tent over the boards with an electric blanket with a thermostat just as a temporary measure for the past few weeks. I’ve been wondering if infra red flood lamps would be ok for winter as our local pub has them around 15ft up on the wall outside and the heat they kick out is amazing. Not sure what the long term effects would be of baking yourself under them would be though.
