21 minutes ago.In answer to a recent inquiry: There aren't any new problems that have mysteriously surfaced. Announcements will be made and safety precautions have been taken in order to safely test the heater. Once water heater manufacturers have been chosen, further field testing will be required involving the application in question be it residential water heating, pool heaters, RV water heaters, submarines etc..UL certification will eventually be sought for each application. So far, heat exchangers and plumbing are not dispaying any problem or leakage.
