A nice 30 is very nice this weather, mind you when it's burnt down a bit it soon gets very cold with all the machines and metal in the shop.

I keep about 7 tonnes of steel on stock at any one time and that takes a large amount of heat to raise it 10 degrees.
I used to work in a workshop with no overnight heating, we had a radial drill which weighed about 10 ton. when this got cold it was like a giant radiator in reverse sucking in any heat we could get in the building.
