This is an excellent vid, thanks! One question, in RV systems I have seen and used there was no pressure tank. The pump would just shut off when pressure was reached and run when there was demand. I'm trying to understand why the pressure tank is needed? In a home system, the pressure tank compensates for expansion as water heats I believe. Is it serving the same purpose here?
Hi Frank, the pressure vessel ensures that the pump starts less often as a result of pressure fluctuations in the pipe. Suppose your tap drips, then the pressure in the pipe drops and the pump starts. A pressure vessel keeps the pipe pressurized for longer, so that the pump has to start less often. This saves power consumption.
I was really hoping to see the electrical hook up for 12v as Duoetto doesn’t have any demos-what to do with the small red and black wires? To a switch? And the large red and black to fuse box?
Hi, sorry too hear the music bothers you. we thought it was catchy. Regarding your question about the wires... The thin red and black wires need to be connected to 12v in order to power the display and temperature control. I installed a 5amp fuse. You can put a switch in between to turn off the heater, when it's not needed. The thick red and black wires are used to power the heating element when running the boiler on 12v. I needs a 50amp fuse. Hope this helps. Lars
@@vanred_nl Ok let me see if I understand correctly… The two small red and black must still go to the DC FUSE BOX- (W 5AMP FUSE)- the small red and black is the one to intersect with a switch to turn on and off the WH. The thick red and black are what actually powers up the heater and must go to the fuse box directly with no switch- I thought I would add a switch in this line…? NOW what about the other little black wire with the connector? And do we just roll up the 240v ? THANK YOU so much for helping me! I swear a video may do well to explain the wiring:))

There is one big mistake the layout - the water tank should be mounted on the lower shelf instead. Big heavy items like that should always be mounted as low as possible as it will otherwise negatively affect vehicle handling.
Hi John, Thank you for your response. I agree with you that it is better to keep all heavy weights as low as possible. In that respect, mounting the water tank under the car near the rear axle is ideal. With this motorhome we deliberately chose to place the water tank in the motorhome for camping in the winter season. Before you call this design a mistake, I think it's important that you can include a little more information in your judgment. The cabinet of the water system is mounted over the wheel arch on the driver's side. A similar cabinet was installed on the passenger side with all the electrics. To make optimal use of the available space, between the two cabinets, the water tank is placed on the wheel arch. Only 30 cm above the floor. Of course, there are also water tanks on the market that fit perfectly over a wheel arch. However, availability, budget, and size have ruled it out. Both cabinets (water and electrical) are almost the same weight and provide a perfect balance. If you take into account that the water tank is 45 liters (ie kg), this is less than 10% of the total weight of the installation. From your point of view, I would be more concerned about a 29kg awning placed on top of the roof (2.50m high) ;-)
So clear and informative. Thanks for sharing!
Thank you! We enjoyed making and sharing it ;)
I have been looking for idea on how to do this on my sailboat. Thanks, this was very helpful. Anything to say about the water heater 2 years later?
Very happy with the heater! Go for it! ;-)
Great video,
can you share the video of how fit it?
Hi supporting champions, what exactly are you looking for?

Can you please provide the links for your basin mixer and shower head? Thanks

What are the fitting thread sizes on the water heater?
Hi Shanice, i'm not sure and I cannot check at the moment. Did you have a look into the user manual?
👍
made with pleasure, thanks :)
What is the brand of red and blue hoses you guys use?
Hi Rodger, the brand of the water hoses is FAWO. I believe you can find them on Ebay. Regards, Lars
@@vanred_nl thanks Lars!👍🏻

I sure wish you would remake this vid without the music. Music is SOO not necessary when it is good content! And trying to understand your technique.
Thanks, i'll keep that in mind for the future. But for now, i'll suggest the 'mute' button ;-)
