Re: Charley Noble, tankless water heater vent
I was thinking of using that pipe (or suitable sized flexible stainless pipe) to the hole where the vent would exit to the outside, and the cap over that. Set up the pipe so that it can be put to the side when the unit is not in use (when not showering, dishwashing) and have a cap that will prevent water from coming in.
The factory told me it was possible to use the same type of flexible plastic 'hose' used for dryers. Apparently, there's not a lot of heat here. That may be the easiest solution. I may fire the unit up and see just how much heat actually is produced before installing.
Not sure what it is in that green statement you don't like. Seems like a business plan that is geared towards providing a low cost but high quality product. As noted, things like Energy Star or a dealer network cost money.
