Am more than a little annoyed that it started leaking having just replaced it. The original had been in the boat for ~ 30 years…
Two working theories: 1] Winterizing the water system last fall I drained the heater tank and separated it from the water system [which was filled with antifreeze] but did nothing more to the heater. First time I had not put antifreeze in the heater tank… 2] The engine was at normal temps when arrived at the dock and began to fill the water system – with cold water. Thought I might have heard a pop from the area of the tank. Could the hot engine coolant running through the empty heater tank heated it sufficiently that the cold water put into the tank itself caused it to crack? Have seen hot glass shatter when cold water drips on it… Brian From: ssjohnson via CnC-List <cnc-list@cnc-list.com> Sent: Saturday, September 10, 2022 1:58 PM To: nausetbeach--- via CnC-List <cnc-list@cnc-list.com> Cc: ssjohnson <ssjohn...@aol.com> Subject: Stus-List Re: Water Heater?'s 4 years old???

It is a 6 gal. Seaward [Whale] unit and only connected to the engine coolant circuit [no A/C on board, just 12 V] Planning to replace it with the same unit as that “should” be the easiest / quickest. Two questions for the group: 1] The heater comes in galvanized steel and white epoxy versions. The latter is more $ but is it worth it from a corrosion or other standpoint? It is not visible so aesthetics are not important. 2] Found both units on Amazon for less than Defender and other distributors. Has anyone bought parts / equipment from Amazon Marine? Usually Amazon delivers when they indicate, but I ordered some ink for a home printer and it still has not been delivered after 8 weeks. Thanks, Brian Ps – Very sad news about Rob. Amazing how a “simple” fall can cause a cascade of events. Not much comfort, but at least it was tangentially boating related…
