Very interested to see this in practice. Please provide details and pics of the installation and final product. I'm guessing your home has an instant hot water boiler and is already plumbed with a re-circ system?

Is the heat exchanger made from 316 stainless?
That"s one of the best corrosion resistance ss. However, it will corrode as well in saltwater, albeit very slowly.
