I am looking to replace my electric water heater. Have been doing some research & came across the Marathon brand of electric water heaters. They seem a little more efficient than your standard electric heaters, but what got my attention is the warranty. Lifetime warranty for the time you are in your home, should you move, then it converts to a 15 year warranty for the new buyer. Also there is no anode because tank is "plastic". So my question is, anyone out there have one of these and is it worth the extra cost, (about double the cost of a standard electric heater)?
Thanks in advance.
BTW - tankless is not an option.
