I think it's really a moot point, as long as the idea is to keep the floor always warm (as opposed to wanting to heat it on a moments notice). Once the heat is in the pipes, it will eventually end up in the floor, minus a small loss through the insulation. Methods of dispersing the heat more quickly will heat up the floor faster, but will also require the heat in the pipes to be turned on sooner.

That's the point, though - some heat in the pipe will NOT end up in the floor, which is the efficiency I referenced


If the heat doesn't end up in the floor, where exactly does it go?

I can see that the fins will make the transfer faster (thereby also allowing cooler water to do the trick), but I don't see anywhere else for the heat to go.
