OK so because I am feeling strong today after 3 great sunny days I think I can withstand some expected corny comments to this question, thought, comment.

Has anyone ever considered either heating the water in their "Aquaroll" or replacing it with a similar insulated vessel that can be heated. Even if it gets heated to say 50 deg for those that WANT (no not need because we all know many enjoy short or "submarine style showers" or simply use site facilities) so even if it gets heated to 50 deg it will greatly lengthen the hot water supply in the van.

OK to pre-empt the next comment, think about it, certainly in our case all water is used hot, washing dishes, showering, making tea etc. We drink bottled water for cold human consumption.

Oh and you don't have to have it on all day, only at shower times actually or a few hours before that.

Ok let's hear the comments and I will dream on!

Over many years I’ve become used to submarine showers, but if I use site showers I think I’m being water-boarded

A poster on here a year or two ago, used an Aquarium, water heater in his Aqua roll in the winter to stop it from Freezing. ( Hopefully no fish in the Aqua roll)

Interesting Grey13.

To achieve say 43 degrees Celsius (I think 43deg is just below scalding point), what power output of heater would be required (Kw)?.

If an aquaroll auto waterfill was used then the incoming cold water would obviously have a cooling effect, I guess that using an auto-fill would really complicate matters, but making sure the aquaroll was pretty well topped up at all times could prove to be an inconvenience.

Not wishing to complicate matters, as I said, I find your idea interesting.

I suppose if you used TWO aquarium, heaters both set to 20ć then you would get 40ć and not get scalded. :evil:

OK the calc's are not difficult but I found this site that makes it even easier. Remember this is assuming there is no heat loss at all from the storage device. I choose 600 watts because I use 2 x 300 watt heaters in my small goldfish pond in my courtyard in winter just to prevent icing over and stopping the water getting very cold. I also have a Perspex sheet that covers at least 1/2 of the pond when it snows etc. Anyway 600 watts adds a load of 2.5 amps to the van load, not too bad and as already pointed out my Truma Ultrastore keeping 10 liters at 60 deg C even if my Aquaroll were at 40 Deg C it would make a massive difference. If anyone ever tries this be sure to check your RCD to prevent any form of shorting as the Aquaroll is generally not earthed. I think I will try this soon, I already have a Aquaroll jacket for insulation.

30 Liters warmed from 10 deg C to 40 deg C using 600 watts will take 1 hour 45 mins

The water from your Truma Ultrastore is already at 60 deg C.

Grey, you obviously have too much time on your hands, which is nice, all this thinking :huh:
I go out with the dogs, Mrs H has a nice long shower, I come back change to the second Aqua roll , just in case and, the Truma combi will have hit the 70c temp and I can get in and have a nice long shower if required. Have breakfast and the water is hot enough for the washing up. I do enough faffing about when away in the van to have another thing to breakdown on me.

A fish tank heater would take for ever and would not be hot enough for anything more than a lukewarm shower. Not even sure about using it in the Aquarol in Winter as surely the pipe to the caravan would freeze first.
Our Truma heats to 60 on electricity in a very short time so with no benefit in heating the water outside I have never looked at the idea though or how to wire it up.
