RE:RE:RE:RE:PIRANHA T15 at "Wash Out Laundry!Found an article on Ella condo unit, Jan 9, 2020. The price of that system was about $70k. The CEO is also mentioning in that article that the utility business model that they abandoned was not the right move. The article also makes it sound like it is Sharc's idea to recover thermal energy from building wastewater, 10 years ago. As I found out, even for residential single homes, products to recover some heat loss from drained water existed more than a couple of decades ago so that may answer some questions how come an invention like this is not taking off. Perhaps because it has competing technologies. Anyhow, results will speak for themselves.
