I have a central heat pump in my house, but it doesn't heat the basement very well. My solution for awhile was to run Folding@home on my server, since I figure pretty much every computer is a 100% efficient heater as well. I eventually stopped because I work in my basement and the server was way too loud when running at full load, but it did a reasonably good job keeping my desk area nice and toasty.
