Dave,

I use a gas jet heater.

I turn it on when I am having dinner and the shed is warm in 10 minutes.

I turn it off as you cannot hear the TV and once the chill is out of the air it's OK.

The wood heater idea is great but I t takes a while to heat up, great for all

Day in the shed but not that practice for a few hours work.
