June

Ok so Marius was going to spend Pinksteren on Jan-Kees.  Even though Marius helped a lot the last upgrade trip in April/May I still made a new ‘start-up’ list ( from Marius and for Lam) on Thursday June 1st.  I was barely done emailing this list to Marius, and my phone rang with Marius . “We are here in this luxurious boat, what do I need to do” .  Quickly I gave a run down…Flip the battery switches, plug the hot water heater in,  open the front hatch, fill the water tank, put the fuse back in the water pump line, let the water run” .   I also had to tell again where the fuse was located.      About 15 minutes later……A Grolsch ringtone…Marius again…”The water is not not running, and the head pump is not running either” .    ….”Ok    we know there is shore power, because the lights work, so grab a volt meter, from under the sofa and check if the batteries are 12 V” .     ” Yes they are” .   …..”Ok .  follow the lines from the battery…there should be a red and black line going to one of the 5 plastic conduits on the port side” .dc1      ”  mmmm you mean these rolled up lines?”

 

Now lets look tot he battery…How many connections on each pole ?   OH only Odc2NE…..so from the alternator.

 

 

 

 

 

 

 

 

So Ron who was installing  the Kabola unit, must have removed the lines, because they were in the way.  As soon as they were attached, all pumps were running.

See now 2 connections on each pole of the battery.  The alternator and  to the DC circuit.

 

As “work” Marius measured the height of the sink drain, This decides if we need a grey water tanks pump for the sink, or a straight hull through, like we have at the washing machine.  Luckily the bottom of the sink is also 60 cm of the floor, like the washer through hull, so we can safely make a straight hull through, which we might also use temporarily for the shower pump.

Once we have enough time we will buy a whale gulley IC, which is basically a drain mount  with the electronics and the pump a bit removed from it, to pump it out directly.  Probably best with a douche tray.  Marius measured the size and it was 76 X 96 cm wall to beam on the wall of the boat.  If we use the bam as bottom we have 86 X 96 cm, which will be a good size for a standard shower pan.

Plumbing

Plumbing has been done in copper  (hot) and Tyleen (cold).

There is a water tank in the front locker, connected to a Jabsco pump with a small pressure tank, the connections are 16 mm Tyleen (also called pe which has lope or hdpe in it,  the cheapest lines have a maximum pressure of 6 bar  which is 86 PSI)

Hot water how long before it is hot?

We have a Vetus WH 45 ( or 31) hot water heater (boiler, clarifier). The heating lament has a built in thermostat.  It is also heard by the engine when it is running.

The temperature should be kept above 60 C, so we won’t get legionairs disease.
When he engine heats up the water it gets to 80 C.

The  boiler is located on the front port side of the engine room, from there it is piped to the hull of the boat and then forward to the shower.  the pipe is 16 mm brass, and the distance from the boiler is about 3.5 – 4 Meters.  So with a diameter of 16 mm the volume of 1 meter pipe is  0.8 * 0.8 * 3.14 * 100 = >200 cm3, so 3.5 Meter is about 700 cm3.    1 liter is 1,000 cm3, so the amount of cold water which has to flow through the pipe is less than 1 liter.  Which is not a big loss.  Some boats have the hot water circulating always so there is never a ‘cold’ moment and los of hot water.    But ‘wasting’ less than a liter of water with a shower, is costing less energy than constantly having the warm water flow in a loop.

With the new Central heating unit, we wil select a model which provides CV heat and Hot water.  We could get rid of the Vetus, but why get rid of it when it is still good? there is enough space.   We have a few options.
1.   we use a T valve.  use the Vetus when warm and the CV furnace the rest of the time
2.  We plumb the Vetus > Cv furnace  > hot water line
