That, in itself, seems to be anti-conservation - you can't simply use as "little" hot water as you please - since the tankless heater may not sense it.Rinnai seems to be a good brand (it's the only brand my commercial HVAC friend installs).Bear in mind, it is sometimes easier to relocate the (tankless) water heater so that it is sitting against an exterior wall (so you can easily vent it) and re-run the plumbing to it, than trying to get the necessary large vents (which typically cannot be shared) run to an exterior wall.

But i am not sure if this company is a scam or not. i tried to check it online but couldn't find anything wrong with it.
