Not sure if you're serious, but having spent the last winter without central heating due to rather unfortunate renovation works timing, I'm really not sure this is a good thing. There were several consecutive weeks where the temperature inside would never rise above 10degrees celcius as we only head a small petrol burner. At night the condensation froze on the walls (outside temperatures of -10 degrees celcius). Sure enough movement keeps you warm, but basically you're always cold unless you're moving. I don't think I ever felt worse physically. Did gain quite some respect for homeless people in cold places though.
