Overalls are good for keeping the heat in, also not standing on a concreate floor helps.
i`ve a small bit of carpet i put down when im working on the mini, also got one of these for the workshop, about £85 from machine mart

i warms it up realy fast, but it can get a little to hot in there some times.

Yea, I already wear two layers of clothes, which also comes in handy when welding and you get *woman of ill repute* on your crotch!!

As I say, the floor is insulated with insulation and thick MDF, so thats not too cold.

Just been testing the heater I got. Seems to be a good one, I'll see if its up to the job later tonight!

the good thing about the patio heaters is you can use them out side as they dont heat up the air

It's actually more efficient to heat up the air, rather than direct thermal radiation heating. Warm air only needs to be about 18 - 20 deg C, for it to feel comfortable, and that is quick and easy for a convection heater to do. electric fan heater would work well for this.

Thermal radiation (IR radiation) takes MUCH longer to heat up the same area to the same temperatures, this is because it heats up the surrounding walls, floor, objects etc., and these SLOWLY warm the air up. Thats why the most efficient gas fires in houses have a convector on the back - to transfer heat more efficiently to the air to warm the area up, as opposed to surface heating (which would mean that the room would be colder for longer, and therfore the fire would be on high for longer too).


In my garage I have two old 2Kw electric oil radiators that I mounted to the wall near my work bench, and a small 1.5Kw fan heater mounted on the wall near my mini......fan heater warms the garage up far faster than the two oil filled rads!

I'm actually thinking about making a small heat exchanger on the roof of the garage, basically an insulated glass fronted box with large diamiter pipes painted black. This will be warmed naturally from the heat of the sun (when it eventually shines), and a small low power fan will force air through from the garage, into the heat exchanger to be warmed, then back into the garage to warm the air in there. Free heating!
The heat exhcanger will still warm even when the sun is not shining brightly due to clouds - as long as the cloud layer isn't too thick.

Will cost me nothing to build, so it's worth a try.

ok, i have just been down the garage in a sweatshirt, tshirt and long sleeve top and combats for about an hour and a half to start making my new door cards. this involved lots of standing around and not moving my body much only my hands. i had no overalls on and no heater going and bearing in mind its mid november it was nice and warmish down there! where i was leaning over almost constantly i have a slightly aching back tho! another layer or a heater would have possibly prevented this tho!
