There’s no such thing as a 100% efficient “engine”. But in this case, since the waste heat is put to use (heating the house), OP thinks there’s a loophole.
But, house would also need to be soundproof. Any noise leaking to the outside is lost energy.

Ah, but that’s by design: it also acts as a soothing white noise machine.
Then you might point out the exhaust and all it’s associated wastes, but that’s by design: it produces a heady and aromatic product for recreational huffing.
Then you might point out the vibrations, but that’s by design: the engine also provides invigorating massages to relax taut muscles.
