I live in a very old house, with mostly double thickness brick walls only the front could have insulation pumped in, so it is hard (so expensive) to heat, plus at my age I feel the cold. So all in all, my heating is on for a couple of hours in the morning and then again in the evening. It's not on high though, living room is 18C at present.
I was with Green energy so got caught out when the company folded, my new monthy direct debit is going to be about £122 according to the latest email info I seem to use more gas than Ofgem's 'medium' but less electricity, I wonder if that means it would be better to top up the living room with a halogen fire, rather than turn the c/heating system thermostat up when it gets colder?
