Love that GBA presents on so many topics. Is it possible, though at the conclusion of a thread for GBA advisors to condense many of the varying inputs into some kind of general consensus guidelines on the topic? Perhaps a detailed library could be referenced with more than drawings.
Is it just me or do other people stop when they see a thread they want to read because they're not sure if they have the time and stamina it will take to delve into all the asides and redirects that will likely leave them with more information but less resolved on the topic.
For instance, in reading on reclaiming heat from domestic hot water use. I think it is good to limit the distance to a fixture from the hot water heater and to use 3/8" pipe in home runs to each fixture save a tub where more volume is needed. After that though I am not sure if adding a recovery or alternate system is a good thing? I would hope the solution after installation would save more than a couple of bucks and work as simply as possible.
