mains water heater for my 34 foot

id like to add a water heater to the boat.. currently the only way to get hot water is to run the main engines.. which is sort of a useless way to make hot water as you cant just let them idle while in port.. ?

so i was thinking about adding a hot water tank that plugs into the main power from the dock..
would something like this work?

there is plenty of room for it by the water pump..

Yes, it should work fine.


I am a little curious what kind of system currently heats hot water from your engine. Usually these are water heaters of 6 gallon capacity with an electric coil and a coolant coil which circulates engine jacket water through it for heating. Are you sure you don't have one. If so just hook up power.

If you do use the on demand water heater in the link above, plumb it into your existing system in series so it will act as a booster.

What kind of boat is it? Is it gas or diesel? I would just put in a marine water heater with a heat exchanger in it. If it has a water heater now, it probably has a 120 volt element in it. What brand and model is the current water heater?

Most likely it has an electric water heater with a heat exchanger hooked up to the engine. Since the heat exchanger is heating the water, it is likely an electrical problem. Is the circuit breaker turned on? Have you looked at the wiring? Is there 120 volt wiring going to the water heater? If you donít understand marine electrical work, get someone knowledgeable to look at it.

Those small point of use water heaters don't heat water as high as a typical home water heater. They're ok for a sink or one quick shower. They don't keep up with the heat loss so if you use hot water at a high rate it gets colder the longer it's used.

To be honest my dad never used the water or anything else really. Just unplugged the boat and went fishing and plugged it in when he got back.

There is a breaker for hot water. It is on.
I wonder if it's tied into the generator and not the shore power? I have not messed with the boat switches. I don't even know what some do.

The refrigerator, the freezer and ac works on shore power.

I'm going to be going to the boat this weekend. I will take a bunch of pictures and post them up.

Aaron,

Here's what I installed in my 34 LRC over 10 years ago and recently replaced due to a tank leak. It fits just inside the fwd ER door to port.

Perhaps you can verify the AC power connection and function of your tank. Let us know what you find.

Usually anything that works on shorepower works on the genset too, and vice versa, by means of the Genset/Shorepower switch.
