In regards to on demand hot water heaters, I have heard that
the biggest reason that causes these units to fail over time
is because they are open systems heating raw water as it
passes through them. This eventually causes the heat
exchanger itself to fail. So I have been told it is a good
idea to add a nice big Y-strainer in the supply line to the
unit. I believe most come with a small strainer in the
supply but I was told to remove it and add a nice big one.
Just wanted to toss that idea out there to anyone who might
be planning on installing these units.
