tubular heaters in sheds

I've had a good price today to run a light and power socket into each of my three sheds, so I'm looking to put in the greenhouse tubular heaters for the buns for Christmas.

Does anyone else have them, and what length heater do you have (I believe each 1ft=60w), and does it provide sufficient heat to keep off the frost?

Thanks!

:wave: I have a 6 x 4 wendy house and have 2 tubular heaters in there. I think they are about 2' long (they were from Argos). I only put the two on together during very cold nights.

They are good because they just take the chill off. I also have them on timers and set them so they alternate and don't get too hot - I think they have cut out safety things in them anyway but just wanted to be cautious.

ETA - These are mine: http://www.argos.co.uk/static/Product/partNumber/4151333/Trail/searchtext>TUBULAR.htm

Thanks for that - I think I'll get a 4ft one for each shed then.

The good thing is they look really cheap to run, so worth it when we go into the minus degrees temps.
