Elgo,
Nice job on the shower water heat recovery. Nice video, too!
But I'm curious how you determined, "conserve about 50% of the hot water energy"?
I'm not challenging it... but I would like to know your method of measurement and calculation that brought you to the "50%" number.
Being able to save 50% of energy anywhere is definitely a worthy victory.
Best,
