I was wondering about a system like that (usually while taken a shower :P) The coil around de drain seems a waste of copper? The system I was thinking about had the drain inside a bigger copper tube that supplied the cold water.
It seems a lot simpler and les labor intensive to me (if u can find the tubing)?

Sadly I can't use the system. I'm surprised by the 30% recovery that's a lot of heat. Unfortunately still most of it is going down the drain.

What you suggest does have merit, however first off you're putting your drain inside a supply line, and if the drain pipe developed a leak, you may never know it, until you got your water bill! Also there's the risk of contamination. With coiled supply lines around the drain pipe, leaks in either would become apparent. Also there's the cost, ever price large copper pipe and fittings? It becomes readily apparent that it's cheaper with smaller copper lines even though you are taking about more length. By the time you added up all the fittings, and reducers your pocketbook would take quite a hit.
