Hi Barry
This has been discussed on the Caravaners
Forum and is does not sound easy to install to meet regulations.

have seen a lot on buses/motorhomes so must be some way around it, i am sure some of the "britz" campers also have them .... it would HAVE to be external but...... now way in the world could it ever be inside, even with a flu set up

Be very careful buying off Ebay as if the article doesnt meet Australian standards it will be illegal to install it anywhere.

Thanks all, Motherhen, after reading the Caravan'sForum Thread I will stay
well away from this idea, for a long time by the look of it. Proper compliance appears to be a real issue. Thanks again .

it does not look that bad a unit and you simply could ask the seller if it does comply ???
checks on that sort of stuff i dont think is that hard to do

We've had one of the ebay ones installed in a shed for a few years now and they work extremely
well but I wouldn't put one in a van.
The safest (but expensive) option would be one of the Webasto diesel jobs, you can get one that heats the water and also the air to keep the van nice and warm.
Very safe as no fumes.

We have been looking at a HWS for our Jayco Camper. The best I have come up with is the 12v/240v AusJ Duetto HWS. Providing you have power either 12 or 240 volt this seems like the most economical/easiest solution for us anyway.

12V @ 25A is 400W. You need a serious battery bank to supply that for very long.
Most 240V electric jugs are 2,000W or 2,400W so don't underestimate how much elctrical power is required to heat 10L of water.
Even on 240V this unit is only 1100W, which is OK if you have mains power.

Peter
I agree with what you say and yes the draw is very heavy on any electric element. But if you are just going to use this for hot water for dirty dishes and maybe a bit of a wash, it maybe an alternative.
As far as I know you can not mount a instant gas HWS in a van/camper? The alternative is something like the Coleman cube or the Truma. Another is Suburban, they do a gas storage hws fitted to alot of vans, which will set you back
well over $1000.

After seeing about a dozen faulty Truma HWS in a van repairers in
Geraldton WA I would go for a Suburban.
They said they just rip out the Trumas and replace with Suburbans.
Ours is 240v and gas so runs on the park power when hooked up and gas when not.
Only allows short showers though as 23 litres doesnt last long.
