My existing residential duty 30-gallon water heater just failed. I've been overwhelmed with the available replacement options and opinions as I surf the web and this forum....
My proposed solution is another residential duty unit that appears to be very well thought out and should never fail. It is a Rheem Marathon 20 gal water heater with a 120V 2KW heater. Has anyone else used one of these? Tank and outer shell are non-metallic and have a lifetime warranty. Thick foam insulation should keep the water hot for days. Not cheap, but neither are the "marine" water heaters that likely wouldn't last nearly as long.
For heating while cruising, I plan to put in an external exchanger (double wall plate type) mounted to create a thermosiphon using the drain and the relief valve connection.
