Question on Hot Water Heater

[dansk]

We have a Beneteau 331. I have verified that engine hot water reaches
the hot water heater. But I have been unable to get hot water at the
faucets. Does anyone have an idea of what I should look for?

Regards,

Bob

[Robert Lucchetti]

Bob:

 

Please confirm that you do/do not get water out of the hot tap of the faucet.

 

Is your problem at the head and the galley?

 

If you do not then there is clearly a blockage. Work your way backwards from the faucet to force air from section to section.

 

Remember the water coming off the HW tank goes into a manifold and there are seperate taps for each faucet for hot. There is a seperate manifold for cold. On the oc321, the manifolds exist under the hw tank. You may end up taking out the hw tank. Doable but a bit awkward to get done. If you get that far, let me know off line and I will walk you through the process.

 

Good hunting.

Bob,

Thanks for the reply, I do get water out of the hot water tap. It just
isn't hot. Is it possible I connects the fresh water lines backwards
to the heater? BTW in our 331 the manifold is in the head under the
sink. The problem is at all the faucets on the boat.

Regarrds,

Bob

Bob,
Sounds like your hot water heater is (was) bypassed for winterization.
Either the inlet and outlet were disconnected and connected together with a
short length of hose which means you have to disconnect the "jumper" and
re-connect the inlet and outlet to the heater ( they will probably only
reach one connector each and I don't think it matters which is inlet or
outlet or
There is a bypass kit installed with valves you have to realign to get the
water (cold to flow into the heater and the hot to flow out. Look at the
heater and the situation should be fairly obvious.
Good Luck.

Check to see that cold ater is getting into the water heater and that it has
not been bypassed.

Did you do the winterzation or someone else.

Does it work when you use the 120 system

The 331 can heat the water two ways

One by the engine and two from the 120 volt system

I winterized it. I removed the bypass I had put on last season and
reconnected the fresh water lines, hopefully in the correct order.I
couldn't verify it worked with the 120, so I ran the engine and
verified the engine coolent lines on the water heater were very hot.
But still no hot water at the faucets or showers. Does one have to
wait a long time for the water to heat? Shouldn't it work with the
inverter running?

Sorry this is my first season with the boat and I don't have a dealer
to go to for help.

Thanks all.

Iwill check the hose layout this weekend.

I do remember the hot water lead to the

head has to connect to the silver metal fitting

that goes to the head. That is the one tied down

to the hull. You might check the drain on the

right side to see if there is hot water in the tank.

It's the one that you drained the tank in the fall.

If hot water is there its not the heater but pipe

problem or maybe a blockage

Bob,

If you're getting water from the hot taps, you have connected the lines
correctly since the inlet should have a check valve to prevent hot water
backflowing into the cold lines.

The water heater does not normally work from the inverter.

The engine should have to run for a while to heat the water... longer than
1/2 hour. It may take a minute or so to get hot water depending on the
length of the lines.

Is the engine running at normal temperature? Sometimes you can get an
air lock on the water cooling loop, but if you feel hot water at the water
heater from the engine run, that should eliminate that issue.

I guess the next step would be to plug her into shore power and see if you
get hot water. This would point to an airlock in the cooling loop. If
not, then you'll have to insure you're drawing water from the right side,
but it's unlikely you could connect that incorrectly.

Dan just to add ... leaving the engine in a low RPM idle condition will not
create much hot water - even 30 minutes of idling will barely produce tepid
water. Our 56HP Yanmar needs to be put to work before it will deliver much
in the way of hot water.

Thanks all, your suggestions help a lot. I will take a look this
weekend. The other thing I notice is the water pressure is very weak
on the hot side of the faucets. I will check the temp of the water in
the tank and check for a blockage.

Thanks.

True, but it would be warm enough to determine that it is connected

[Dan Gingras]

That MIGHT indicate that the two lines are reversed and the check valve is
not working too well. I might start by reversing the two lines and see if
the flow improves, if so, I think that would be your problem.

I had this problem on my 6 year old water heater in my 461. I could feel hot
water from the engine or Espar diesel heater running through the water
heater in fact the inlet and outlet hoses themselves were too hot to hold
for long periods, but I only got tepid water at the tap.

Thinking about it this started after about three years of service and it
just took me three more years of stuffing about with it to give up on the
water heater and replace it. When I pulled the old heater and got it onto
the dock some very nasty looking green & brown gunk flowed out and I was
really glad I replaced it (this gunk never showed up at the tap). With the
new heater the engine or heater heats the water to shower temps in 30-45
minutes

All,

Just an update I had the hot and cold connections reversed. There
must be a check valve in the unit. Thanks all who replied.

I've got a "Quick Nautical Products" hot water heater on my B57 that suddenly quit heating under electrical power (engine running still circulates the radiator water through it's heat exchanger and heats water).  I've checked the breaker and it is delivering 115 volts to the unit.  Anyone know what fails electrically in hot water heaters and how to diagnose and fix?

Glenn,

 

It could be either the thermostat or the element. A few simple checks with a multimeter could determine which it is.

 

Check to see if you are getting 115 volts across the element. If you are the thermostat is OK and the problem is the element. If you are not getting 115 volts on the element then the thermostat is not switching on and should be replaced. Both parts are standard plumbing supply house parts.

I am going to assume that your brand of water heater is like everyone else’s; they use a heating element very similar to what is in your homes hot water heater. You can test that heating element for continuity to see if the unit has burned out, make sure you have power available at the element and check that the thermostat is ok. How about letting Bob Villa help with a trouble shooting procedure, try this link.

First item to check is the thermostat reset button.  It might be popped out.  To get to the critter, turn off your ac power to the heater.  Check it twice that you have done so.  Take the cover off the heater where the electrical connection is.  You will see (usually black) a box with a red push button.  Depress that button until it clicks.  Repower the unit and see if that solves the problem.  Keep yer pokers away from the unit unless you put the coves back in place.

 

Next might be a failed thermostat.  If you have an ac voltmeter and know how to use it without electrocuting yourself, you can check the element side of the t'stat for line voltage.

 

If that passes, then you have a failed element most likely.  That takes a large socket and a long breakover handle to remove.  They are replacable but you might need a gorilla to help get it out.  They usually fail because of scale buildup from the water dissolved solids.  Scale gets thick and won't allow the element exchange heat with the water. 

 

A tell tale sign that one has scale on the heater elements is the noise it makes.  Enough scale and you can hear sizzling when the unit is on.  Sometimes you can hear popping as water gets through the cracks in the scale and steam off. 

 

If you are not electrically inclined, don't mess with the second step at all.  If the reset button pops more than once, ie within a few minutes of reset then the t'stat may be faulty.  It is usually replacable from builder's supplies. 

 

All the above is in the manual for the heater. 

 

No pun but it boils down to the element or the thermostat usually.

 

There, more than you wanted to know.

Glen,

I can not believe it.  I have a B42cc with a "Quick Nautical Products" hot water heater and mine stopped working, identical to yours.  My model # is BR4212SLV.  The manual states there is a reset buttom to reset.....but I can not find it in the location they said it was in. neither could I find it else where.  I sent an email to Italy with no response yet.

Keep me updated with any finding you have and I will do the same.
If you find the reset button let me know.
The manual is on line if you need it.  Just google "QuickItaly"

It appears they do not carry the model I have.  They have an updated version currently for sale

Guys, The reset button may be only a shiny disk on the thermostat.  It is a bimetal concaved disk that, when trips, becomes convex.  You thump the puppy back to concaved position.  Not all reset buttons are buttons.

When I bought the 40.7, it had been built for Europe, so the Quick heater had a 220 v element in it.  I had to go to the European distributor to find a replacement 110 v element.  It heats very slowly.

 

With regard to your mention of towed water generators, there was a discussion of their use during one of the recent ARC races in the UK magazine "Yachting Monthly".   I can't remember if it was last year or the year before, but there was a general consensus that they worked much better than wind generators.

Check the voltage at the heating element. If there is voltage it should be continuity as well.
