Out with the old and in with the new! The new Rheem Marathon High Efficiency Electric water heater that is! With a lifetime warranty on the tank and an energy factor of 0.94 I am looking forward to seeing my savings add up and my electric bill go down! Thanks to Kevin of Griffiths Plumbing for his usual efficiency, neatness and just all around great service! And...hot water from the tap 25 minutes after the breaker went back on!
