EcoRenovator - View Single Post - Shower pre-heat idea

Tom,

In your cold weather area, preheating the cold water will have quick returns. But I would use copper in the thinset shower floor rather than PEX.

I know we have discussed cold water preheat for showers - can someone come up with that set of posts?

My experience was a copper drain pipe with spiral copper water tubing around it. It captured a lot of the BTUs going down the drain and recycled those into the cold water line going to the shower.
