Garage heater

[85Carrera]

I've got a triple garage which is currently unheated. I'm going to be spending a bit of time in there this winter building a Caterham and doing bits and bobs on the other cars, so am looking for a heater.

Does anyone have any recommendations for one which would heat (or at least take the chill off) that sort of space?

Thanks for the replies.

Insulation is not too bad so will go for an electric heater of some description as I don't want loads of condensation and only want to take the edge off.
