They have similar heat exchanges for shower drains. The copper cold-water pipe to the shower head is wrapped around a copper length of drain pipe. Instead of hot water going into the sewers, your wastewater is only the internal temperature of a tauntaun*; you need less than half as much hot water for your shower to be comfortable (up to 73% heat recovery!) They're about $500 Canadian dollars, but are best installed during new construction.
