I have actually visited George, seen his "warehouse" and done business with him. Though I decided not to pursue further ventures with him, to call him a crook or scam artist is pretty harsh. In my opinion, he is not a particularly adept business man and really under estimates his responsibilitiies and liabilities as a distributor of low cost, imported water heaters (solar and instant). Yes, he over states the virtues of his products and does not appear to understand what is necessary in order for something to be deemed "Made in USA" ... but he is not alone in that department. He is alone in his business, withg no direct emplyees or a distribution network. He is pursuing "the American Dream". He may find that the manner in which he has done so will eventually cause him to loose sleep due to the nightmares of litigation, but in the end, I don't think it will be found that he has broken any significant laws or that he has enough resources to make civil action against him worth anyone's while, except of course the lawyers who encourage this sort of thing.
Generally, you get what you pay for and lthe Buyer Beware concept is well founded.
With that said... I know of at least one Omega LNG Tankless Heater installed and working up here in Alberta that continues to perform, though not quite as well as it might were the intake water warmer and the fixtures upgraded to avoid fluttering (common issue with all tankless heaters in older hmes).
