We are really starting to get cold here. We've bought a portable space heater. It works pretty well, but it is not fun dragging it from room to room.
It cost about half the price of the comparable coil-air blown counterpart, and is rated as using about half the electricity. It is good for a single room of decent size, and is more than enough on half power for a smaller room.
I want to say that this is an original product of China-not a clone, a copy or manufacturing ripoff, but honestly I don't know. It runs about $50US (330 RMB, 56KWon).
This week temps have risen back into the 40s. Hopefully we will have another month of mildly cold temperatures before is drops below freezing for the duration.
Winter is a dreary time, it seems. It is much nicer in pictures and movies than in reality.
