New caravan hot water solution

[Cpd]

I have a caravan / cabin that is used by visitors and the hot water boiler / heater has broken.

Its a 5 litre Truma hot water heater and is absolutely shite and I would like to take the opportunity to replace with something better. 
I only need a small amount of hot water for doing the dishes and serving a wash hand basin,  10 - 15 litres. The shower is electric and I don’t want to change this. 
People who visit do not expect continuous hot water on demand but I would like to make improvements as I go as boiling the kettle to do the dishes is fine by me but seems a bit archaic to others. 
I have looked at  specific caravan hot water heaters but feel underwhelmed by what my research has turned up. 
I am in a remote location so getting specialists in to service a system annually is not an option. 
There are two options, instant hot water or stored hot water, not sure which will be the lowest energy consumer.

just looking for recommendations or possible solutions. 
It needs to be an electric option as I don’t want gas. 
thanks

Instant hot water assuming it’s not used the same time as the shower should be fine. If it’s got less than 3 litres stored, or is vented,  then it’s exempt from the regs. 
 

Can it be fitted above or below the counter - have you got space to wall mount ..?

 

Change of £150 will do it

There is no space above and below is vital for storage.... there is however a cupboard about 1m away so could fit it in that as the pipe work already runs through this location. The consumer unit is also close and I could get a dedicated take of from that. Do you have a recommendation for make /  model @PeterW ? Thanks

As always, I would go for a vented system. But just for hand and dishes, it is hardly worth it.

Boil a kettle.

I agree but as I have already said

and there is just no room to put in a proper vented system as it’s a caravan

I have fitted a couple of these in Offices where they just want a sinkfull of washing up water.

As in a real one  with wheels.

Not a Scotch one that can be twice the size of my house.

 

When I was a student, I rented a caravan and that had a vented system in it. Boiled over once, just got moved to another empty van.

There where hundreds of them.

In my caravan the gas boiler packed up and I installed one of these https://www.ebay.co.uk/itm/274474218804?hash=item3fe7f03534:g:5XUAAOSwFGRfR~dx it fed the shower as well (but won’t supply taps and showers at the same time, dead cheap and easy to instal ?

 Very much a real one with wheels but it’s never going anywhere.....  well not any time soon as I have added external insulation and clad it in wood.....

Easy then.

Air2Air HP and an exhaust HP for the water.

Could fit most of it under the chassis.
