   You may be better off considering heat cable, as supplied in pet stores   
   for keeping reptiles warm, I think they are about 25W, buddy of mine   
   used it to warm up his home made wine fermentation. Also available for   
   pipe lagging in cold countries. Try Ebay in your respective country.
