Heating stored water

[Davey Boy]

Thanks Fezzy, but they just don't work.
It's a sunshine issue, or lack of it....

How about a heat exchanger like I'm running to warm my veg? Just pump water through rather than veg, use a small 12v pump and some fancy pipework :nenau

Only downside there is the car would need to be up to temp which may not be great if you want to wash first thing in the morn but you've only got to let it get to temp by leaving it to sit there running for a while.

I said that ... Alde

I've had one of those solar showers and even on a blistering day it was tepid to say the least..

Someone we know had a gas powered shower on a trolley for washing her horses that seemed pretty handy and fit in the boot of a car.

I wonder if something like that could safely travel on a roof rack providing the gas cylinder was shielded from the sun.

Fancy pressure washing a horse :lol

Thanks matey, but that just sounds scary!!
Space on board really means every thing the further you intend to travel too.

I do intend to go down the plumbed in heat exchanger route though.
I have a nice little unit out of a nearly new Vokera boiler i shall use.
Next question... submersible pump or external??

Submersible pumps don't tend to generate a lot of pressure so a 12 volt Flojet /Shurflo pump as used in caravans and motor homes would be best. They also have a pressure switch so pump will stop start when you open and close the tap.

Agreed but they are expensive and so are the parts that regularly need to be changed, whereas the little subs are cheap as chips and perfectly good for a shower in a van and also a hell of a lot quieter, just my opinion, Rick

Which should be enough, no?
The most uncomfortable feeling I have ever had was sweating under a hot shower in 25 degree morning heat. But even at 40 degrees plus, I couldn't take a cold shower! Brrrrrrr!!!
Tepid should be fine.

Hiya mate I saw this and thought of you https://youtu.be/KAtANlzTcUo, don't know if you've seen it or are still on with this project.
This is quite elaborate but looks like it works bloody well!, the guys voice might send you to sleep though :lol

in my 81 van no hot water but a shower tray so i built a hot water system that ran of off the battery 120a.
i got a 150w 12v water element,a 5lty container,wire fuse and a water pump for a van sub one,a small shower head with a slider switch to stop start water flow.
to start with i wired it up to my car in the field and drew a little crowd watching me.
i timed it had an ammeter in line to see power usage.not pretty but it was an experiment,also a fish tank temp gauge.
i cut a corner off the container so heater could drop in and pump.
put about 4ltr of water in,then connected to battery with crocks.
looked at watch to time.
no running engine it took from memory about 25mins to get to 45c and drew a constant 17a.
now i knew it worked did not kill battery i then set about fitting in van.
the container was marked to give me enough water the head fixed to van wall the wiring was connected onto the battery was fused,temp sender was in so good to go.
t filled up container from sink put it back on toilet floor and switched it on.
that set up worked well but i am on my own.
i found the amount of water did me for a get wet soap up hair/body then rinse off.
easy p easy cheap set up.
i then put in a pid controller to look after the temp so it cut out at the temp i water with a timer,all i had to do was make sure the water was in.
i used the set up for years untill my next van had a shower fitted.
i think the heater unit was about £55.

This should give you some food for thought.
