Basically they found that you would have to completely disable all the safety features intentionally (as they did in the vid) to get results like this. Possibly more of a reality in old water heaters, in the episode they could not get a water heater to do this without serious safety feature modification.
That's reassuring. I mean they had to totally defeat the safety features. I have an old heater in my house. It has always provided great hot water, and still isn't crackling like it's full of sediment and minerals. Also reassuring is the manic news media isn't showing houses that have blown to bits on the evening news. Which in my thought process means that the safety features are working on water heaters as they are currently built. :thumb:
i watched that episode, that was good. i would love to work for them, building crazy stuff all day that would be great. escpecially the blowing stuff up haha.
tankless hot water is an awesome way to upgrade a major appliance in your house. mine is a rental so i never have to worry about doing anything but calling and then a repair man comes out lol. its like 8 bucks a month or something.
