Whew–homes and multifamily buildings sure have a long way to go in terms of both water-efficiency and hot water efficiency. So much of the water the typical home pays to heat gets lost down the drain after it’s cooled in the pipes and waiting for more hot water to arrive. Ever turn on the hot water tap in the morning and what 20 seconds for hot water? 40 seconds? A couple of minutes? It shouldn’t be that way. Waiting and wasting: two problems that can be greatly reduced by proper equipment choices, placement, and plumbing. Easier in new construction BEFORE goofy piping runs are in place, but existing homes can also benefits from tweaking (or overhauls!).
