Hi
I have a Beneteau 423. Hoping to get some help. I replace the hot water tank last year and since then I cannot get hot water. The system works as expected under shore power but not when heated from the engine. It's a purely mechanical system via the heat exchanger so I cannot really see what could go wrong. I've checked for an air bubble, flow valve, nothing seems wrong. It was suggested that the there is a thermal couple on the heat exchanger that may not be opening but looking at the schematics it looks purely mechanical as well. I measure the heat of the engine and it does run cool but the hot water did work quite well before. Is there some thermal couple on the engine that controls the flow hot water heater or something similar? -- Just trying to figure out could be wrong. No a lot of options.
