You crank up your electric heating?
The last flat I had was all electric - cooking, heating, lighting- everything. I don't know how much you guys pay for your power, but my electric bill was touching the equivelant of $50 a WEEK. The cost of running that place nearly bankcrupted me.
Before cranking up the heating I'd invite an expert round, to see if I could lag the pipes better,and insulate my home to the n-th degree.
I moved out of that place within year...
