Water heater reviews needed (post #157782)

Hi,
I"m looking to install a new super efficient water heating system in my home, and wanted to know if anyone had experience with a Navien condensing tankless system (I would only want a tankless that worked at super low or no minimum flow rate so i dont waste water or have to wait so long for hot water to turn on), or a gas condensing tank water heater (I had some info on AOSmith Vertex models).
I have a two story, one shower, 2 bath home, and just myself living here.
Any reviews or suggestions appreciated!

Thanks

You know of course that tankless units don't save energy in most circumstances. Standby losses from good quality tank units are minimal, so you only save with a tankless if the unit isn't used for relatively long periods of time (generally days).

To avoid the wait for hot water you can of course use a circulating system (one of several varieties), or use small point-of-use electric heaters in series with the main water heater.
