Re: Low voltage greenhouse heating

["Dean Smith" <ukha@xxxxxxx>]

I could understand the concern with exposed bar heaters sitting around the
place but if you go for the enclosed/sealed tube style heaters deisgned for
such things you should be ok ?

Keep all the connections in appropriately rated enclosures of course.

Infact TLC-Direct describe these as

"...finished in an attractive cream colour, suitable for use in damp
and
humid conditions, garages, greenhouses, drying rooms etc."
