This is my shed heater, gas, it gets around 0 deg occaisionally here in the desert.
You see I have this theory
being old school I often use petrol to clean up parts, lots of fumes etc so me put flame up high and away from the heavier gas fumes on the ground.
so far so good
Bloody chews up the gas though, 3 nights to a 20lb bottle , thinking of making an adapter for the car gas station filler, heaps cheaper.
