Hello SLZ people! Happy New Year! Well, it's time for our first project of 2015: replacing an old water heater that sounds like Souz Rocket Ship before the take off . . . So, we decided to go with a new tank less water heater at this point. Anyone got good recommendations on model / make that you installed and have no issues with? As well as the installation crew who did a good job with this? Any advise is appreciated! thanks!
