Re: [Amel Yacht Owners] How long do your Hot Water Heaters Last?

Hi Colin,
I think the "universal" element fits all of their models, not other brands.  You are correct that the Quick Nautic is identical to the Nautic.  I ordered my heating element and thermometer from Quick.

Thanks you for the responses. Since this hot water was renewed in 2008 and seems in absolutely spotless condition other than the electrical short to the 230v heater element we will get prices on both replacing the unit entirely, and on just the element this week before making a decision.

On doing an internet search today it seems to us that the previous Nautic 40L Boiler 40L is now possibly the Quick brand? The new Quick Nautic 40L ( )  looks identical to our Nautic 40L.

Giovanni, where did you source your spiral element from? The Nautic boiler refers to a "Universal" element connection/fitting so am I correct that this is a generic fitting and one can fit any brand elements which has the "universal" type fitting?

The option to insert shut off valves to the water heater from/to the engine water was also suggested to me by the Yanmar mechanic. Seems to be a good idea.

Our Nautic Boiler lasted 14 years (boat was used infrequently).  However I believe internal heat exchanger was leaking for some time.  Eventually leak grew substantial causing freshwater to be leaked into Yanmar cooling system diluting anti-freeze and causing coolant to overflow.  This caused a minor mess but no real damage.  I was more concerned about anti-freeze from Yanmar getting into freshwater in water heater.  I would highly recommend proactively replacing these units before they fail.  No fun doing this remotely in a rolly harbor.

By the way, original unit was 45 liter.  New Nautic Boilers are not available in 45L. You can use 40 or 50 liter units.  I used 40 but in retrospect a 50 liter unit may have been a better fit.  But measure first.

Mine, also Nautic Boiler, lasted about 5 years.  The first on failed in the heat exchanger coil (the symptom was a rising level of engine coolant in the overflow tank).  The whole unit had to be replaced.  That one has failed after 3 years in the 220AC heating element and/or thermostat.  I will replace those parts and hope the whole unit doesn't need replacing.
I would carry a spare heating element and thermostat.

Our 2001 model SM has a 2008 model Nautic Boiler 40L / 800W hot water system fitting which looks in excellent condition externally, however our heater element failed a little while back and we were just in the process of replacing the element.

A Yanmar mechanic quoting on servicing the motor this week suggested we consider replacing the entire hot water unit now anyway, ahead of a circumnavigation, as he had too often seen older hot water units ruin perfectly good engines over time. I do not think the mechanic was trying to profit from this as he did not supply hot water units and also had no extra time to fit a new one either.

It would be interesting to know the average lifespan of the hot water systems on other Amels in the group? Is 8 years too long or really pretty good for some years ahead still?
