Hot water in California Ocean - its easy and possible - without loosing warranty

[Robert-ert]

I've gone through many solutions, read hundreds of posts and now I know having water in California Ocean is simple and inexpensive
(especially if you have the possibility of a 230V 660W power supply).
Additionally, we don't irreversibly interfere (we don't damage anything, we don't drill, etc.) with a car under warranty.
What do we need?
- A little courage, basic skills, and basic tools (a 7mm socket wrench on a long handle will make life easier)
- Ideally, space in a closet, which is sometimes taken up by a factory safe-box (and if it's not there, there's no way to even reach it)
- An Elgena boiler, available in 3 or 6 liters, preferably a combi version (12V 200W / 230V 660W) - it easily fits 6 liters and is as shown in the photos
- Hot/cold water mixer solenoid valve for boiler - Truma
- A suitable 2m hot water hose with a 10mm internal diameter, e.g., FAWO
Cost is about 550 Euro and about 4h of your time
and you have about 15 liters 38-40C water enough for 2 showers - in shower and in the sink.

Cześć Robert! Looking at your photos, this seems very similar to the boiler we had in a Ford Nugget camper we rented once. A very innovative solution - well done!

Excellent! I’d love to know how you have done this, power etc

Am I missing something? at 12v it'll eat a leisure battery so it needs to be run whilst driving? If there is 240v available then chances are you're on a campsite so use their showers?

I’d be interested to learn more as well about of it works in practice. It’s not really usable on a campsite unless it’s a nudist site (even then, I’m not sure people would be impressed with you soaking the pitch with soapy water).

But can be handy for wild camping. Certainly useful there for washing dishes in the sink. But how long does it take to heat up those 6 liters and how much battery does it use up?

yep 12V while driving only, but 230V also on "wild camp" for example from ecoflow

How to power up it while camping "wild" ?
- leisure battery only when driving - BUT when water gets hot 75C as this boiler can do ! it hold (just add some additional insulation, as I did - on the picture) for many hours.
I have 36C after 12h in my test.
- 230V - much better and faster, but... you need additonal power supply - in my case its Ecoflow Delta 2 + Ecoflow 800W alternator charger - solution described on this forum

Give me a bit of time will prepare full tutorial how to do it

So you also need to carry around an enormous heavy lump of extra battery?

We had something similar in an eriba caravan 20+ years ago.
The memory generates 2 questions:
1. How is easy is it to drain down for winter?
2. When you forget to drain it down what damage will the leak do?

hahahahahah
There are no free lunches in life, there is always a cost to something...
if you traveling not staying for few days in one place - 12V will do the job without "heavy lump"

1. easy - 1 minute job just take the boiler out - two clamps and is out
2. It depends on how you protect yourself - I have the boiler in a tight "foil bath" with the 10l capacity so no problem at all

Looks like a nice solution, I would be interested in seeing the Tutorial when you get a chance do do it.
