At least, I think it is. This is the cover of the e-book, which has just shown up on Fictionwise. My other e-books that are for sale there have the same covers as the print editions, so I'm assuming that this the cover of the Central Heat print edition, as well.
Wildside modified it from my original, but I'm happy to admit that they improved on what I sent them. I'm also happy that they kept the nifty background illustration as well as the basic theme from my version.
