"Holy Wah!"
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.
Some installers write to the protected "Program Files" or "Program Files (x86)" folders. These are special folders requiring elevated permissions. (This is why a lot of modern programs install to your user folder or AppData instead).
Unfortunately, these same permissions also allow writing to OS files. It's good to be wary. You may be interested in a Sandbox program (I use Sandboxie). Someone else here can tell me if this is unnecessary or not useful in general.
