Hi Danny,
I use oil filled radiators for the reasons already stated - minimal fire risk with dust around. Screwfix have them on offer at the moment. Mine is the basic 1.5kw unit for £34.99, but a timer version is only £5 more.
Another thing worth doing is dry lining and insulating the walls of any single brick structure (garage, outhouse). A bit more expensive than just a heater but very effective.
And some form of insulating matting on the floor works surprisingly well to keep your feet warm.
Or my other method is a second pair of thick socks
, but please don't ever consider wearing gloves when turning.
See you at the club next week, hopefully,
