Portable gravity fed water heating system?

[elsparkio]

Hello All

I would like to open a hair shop in a area which has no utilities i’e water/electricity etc. (think middle of a field)

I need a solution for the hair washing situation.

In my mind i’m thinking the solution is having a portable water container which I can fill up and bring from home every day, sit it as high as possible in the shop, which would then plug into a water heater (which is powered by a generator) and then into a shower head.

The things I am struggling to find are low wattage water heaters (so as not to eat all the generator juice) and also if the pressure is going to be enough to use with the heater and shower head.

Is there something on the market that could heat up water without sapping too much power.

Any help/advise would be much appreciated.

Thanks

two variables here
how much water do you need per day and how big is the gennie?

As I'd be bringing the water in i'd probably only be able to handle lifting about a 15/20L tank to the ceiling, although i'm not sure how many hair washes this would do? I'll have to do a bit o research on that one.
The generator would be at most 5kw although around 2kw would be taken up with other electricals so probably about 3kw left.
