Numerous aroids are thermogenic. Years ago I had a Sauromatum and the central spadix was warm to the touch on it's first blooming day. But that's the most I've ever felt from them. Usually each bloom only lasts a few days, so it would be limited in time as well as space. And except for the skunk cabbages and a few others, they are mostly tropical anyway, so you would need to provide them with heat in order for them to produce any.
But just about any plant is highly thermogenic, if you dry it out and set it on fire!
