On Demand Electric Water Heaters
Anyone have or had one?
I've only seen them in homes in Europe, but was wondering??
Are there 12v systems??
My brain has been slow on the uptick, probably a result of all those solo voyages
So, just like my fridge and freezer which are now running on 220v shore power I just realized that my solution is a 220v system, which there are plenty of here in Europe.
I just need a system to have hot water and i am trying to come up with an alternative to using my 120v water heater with a 220v to 120v transformer, WHILE connected to 220v shore power.
Problem solved. thanks

With your long run plans, consider an isolation transformer ($$$$). We have one on Bay Pelican and it allows me to plug into European 220 volt shore power and end up with North American 220 power. This allows me to run the 110v appliances.
For our members outside of North American, North American 220 volt shore power is made up of two legs each 110 volts. Bringing 220 volt North American into the boat,we can the physically split the two legs into 110 volt power as if there were two power sources, each 110 volts.
Richard, for what it's worth, the Splendide probably won't run off a transformer converting the Euro power down to 110V. The reason is that a transformer, while it converts voltage very well, does not change the frequency of the AC power. So you end up with 110V 50hz, not 60hz. Something like a water heater won't care, but I'll bet dollars to donuts that the Splendide won't work properly. If you can keep running it off the inverter, that should work.
...On the water heater, I can think of another possible solution. Depending on the heater, it probably has a removable heating element. You might be able to get a replacement element that is rated for 230V. If your boat is wired such that the 230V shore power is present at the water heater, then it should work fine. Just try to match the wattage of the heating element. A call to the manufacturer and/or a careful look through the parts manual should tell you if this is possible.

You guys with U.S. shore power using split phase power to get two feeds of 120 be careful with adding a 220 volt heating element. If you do you are connecting those phases that were separate and safe and creating a dangerous situation with breakers and hot plugs etc. 220 on these systems is not a good idea.
In summary it is a very good arrangement to use split phase power to provide two separate pools of power, it is not safe to then link them together using 220 volt loads.
So how do you explain all the boats that have one 50a or one 100a 125v/250v cord yet run both 125v and 250v equipment off that single cord with out any issues?
