My house feels like an ice block in the winter, and as I am at home on my own during the day I don't want to put the heating on and heat the whole house when I just need to heat one room. I have been looking for portable heaters to use in my living room but am confused as to how much they generally cost per hour to use. I borrowed my parents oil filled radiator and according to my energy monitor it cost 12 p per hour.
Does anybody know which would be the cheapest per hour? Halogen, oil filled radiator etc
