Cold snap here in California, and my garage office is starting to feel like Bob Cratchit's workspace. My little Holmes heater tries, but can't quite do the job. I have a Toyotomi portable AC that does great work keeping me (and especially my computers) from frying in the summer, and I'm thinking of trading it in on a newer model that also doubles as a heat pump.

It turns out about 8000 BTUs of heat. I seem to remember you divide by about 3 to get watts which would make it the equivalent of a 2666 watt heater (!). Sounds much more efficient to me than a pure electric heater, but am I screwing up the calculation somewhere?
