All the "why can't you wait the extra 20 seconds" comments will come as they do in every thread like this, but my answer is "just because I don't want to."  Up north we had a dedicated loop system because there was easy access to the crawl space but down here we have to use the "integrated loop" which isn't quite as efficient. This is the one I installed: https://www.amazon.com/Watts-500800-...81636251&psc=1. |
The water savings is another plus. You get a few seconds of warm water out of the cold water faucet if doing the integrated loop.
There are tankless water heaters that have this function built in.
