What was the previous system?markopas wrote: ↑Apr 10th, 2017 9:56 amPlease don't think a tankless water system is an upgrade - I've had one since I moved in to my house and probably one of the first in Canada under new builds. Yes that system was a piece a junk and units have come a long way since then but I still think that going with a conventional tank system is a better option or at least rent a tankless because of the maintenance required to keep these things running.
If you want to invest in a really good tankless there are only two good ones on the market (Rinnai and Navien), we replaced our failing unit after 6yrs to a Navien. I think if you want to go tankless you need to go with a two unit tankless system and have them side by side in order for it to act like a conventional water heater.
If you want to use a tankless system like the europeans then you need to usually have a small unit at every tap which guarantees you hot water at tap rather than running the hot water tap for 10-15sec. The closer your tap is to the system the quicker it will cycle to hot water.
Also I have a small house, so piping is not that far away from the basement, so don't think there will be more than couple of secs different between conv and tankless.

Fact check, none of the above is valid.
