Merry Christmas...Take all the HOT showers you want

Yes, I have a new water heater. So this Christmas, showers on me! All the hot showers you want in fact. Long story short: Plumber who installed is (shock) no longer in business. Store where water heater purchased no longer carries that brand (warranty issues -- go figure) and so... I own a new water heater (different brand, different installer). But the hot showers are oh so nice, Merry Christmas !!! Trust me, I know it could be worse, I am not complaining............. really!
