I have a 2006 2565 cruiser and It doesn’t produce any hot water for the fresh water system while the engine is running. All the hoses to the engine look good. I don’t see any valves in the lines to the engine. Any ideas what the problem might be?

If you don't see any valves, I think they may be hidden. It sounds to me like a valve is closed. The other thing could be that there is some type of blockage or maybe even the system is primed enough to flow antifreeze through the hot water heater. I would pull one of the hoses and see if it has fluid in it. If not, I'd prime the system and run the engines and see if the problem goes away.

Dont know if OPs vessel has a engine jacket water coolant circuit piped to a hot water tank or not? on our 4160 it take a hour or so running at sea under load for engine coolant to actually heating up the hot water tank to "warm", especially when the hot water tank is "cold".

I assumed he does since he pointed out that the plumbing running from the engine to the hot water heater was there, but reading his post again, that might be a good place to look. Clearly, there does need to be hoses running from one of the engines to the hot water heater to have the ability to have the engine heat the fresh hot water supply. Without that, you will only be able to heat the hot water either plugged in at the dock, or when the generator is running if you have one.

Have to wonder how long and under what load the engine that supplies jacket water to the water heater has run? Maybe OP should check if hoses from engine to water heater are cold/warm/hot after running engine under some decent load and what the engine jacket water temp gauge indicates its temp is at helm gauge? We have to run for about a hour or so at 1/2 - 3/4 throttle to get tank hot, especially when starting with tank cold? |

Just off topic (like I am doing here) = On the Facebook Regal forum a lot of posts (too may people) starts with a new post and after 10/20 reply's goes from engine wont start to replacing front seat cushion. Too confusing for m to try to follow OP's question so just look at a few and then give up searching  Also, Usually no info on boat etc., etc. Thanks that our forum is much more organized (or much less diluted) ! Happy New Year to all! |

Had same issue with 290, engine water was blocked and not circulating into hot water tank at tank. remove lines and flush out.
