I love tankless heaters, we are installing 5-10 a month.
We finally did a copper repipe this week and it was actually nice to be sweating copper again! Although PEX-A would have taken about half the time for real. Don't like tankless heaters? I guess it's a matter of taste, and retrofitting them to older houses is a total pain in the ass, but we enjoy putting them in and always try to make them look great. Anyway, nice intro, welcome to the forum.
