Electric heating converts practically all energy into heat, making it ~100% efficient. You can make statements about cost-effectiveness compared to burning things, but not all houses can.
CHP configurations are more common in colder climates with district heating, so their "waste" heat during generation often isn't wasted at all.
So yes, I do think they make money aswell
By this definition, no source is clean, because there are always "better uses" for energy.
I've never heard of farmers who intentionally make their produce worse before selling it, they simply sell it cheaper if there isn't enough demand. If you make a lot of houses that don't end up popular, do you go and smash the roof and take away the plumbing, or sell the same house at a lower price?
