That is a serious element 3000w, most jugs/kettles are only 2000/2200w. Check your circuits.

We have electric instantaneous hot water at home. It is 3 phase, but we generally run it on 2 phases most of the time as it is hot enough most of the year.
So 22kW 3 phases, 14kW 2 phases or 7kW 1 phase. 7kW is simply not hot enough.
If you have very cold water to start with like in winter, the hot water is not as hot as in summer.
The 3kW instant hot water is only a fraction of the heat of a proper system. Either it will produce a dribble of hot water, or what one would consider a good volume but barely warm.
You simply need to put X amount of energy in in a given time to get enough hot water.

Most home hot water tanks have a 3.6kW element.

I am not much of a free camper, so will always be in a caravan park, so no external showers are needed. I just need hot water at the sink to wash the occasional dishes and this and that.

If always plugging into to a 15A power supply then this should do what you want.
However with some sellers selling the identical items for under $12 I think I'd worry about quality & safety.
With 240v it could be a potential killer.

My preference in that situation would be a portable LPG water heater like this...
I was looking at these also but i would like something permanent. As its an older caravan i like to retrofit everything to make it look as "OEM" as possible. Just could not find a suitable place to mount and operate easily.

So simply run your kettle for another round & add hot water to sink's cold water for cheapest most uncomplicated option, unless you want to make a mountain out of a molehill!
Really, is hot water coming instantly out of the tap that critical, maybe, we have ice ream from our fridge in Northern Australia! Ice cream or instant hot water... it's probably critical to keep Wifey happy, if you're are desperate.
If hot water is not hot enough add another kettle load!
Years ago I heated up 200 mils of water on my 3.0kVA UPS (Uninterruptible Power Supply) for a cup of coffee for 132 hours per week work load, during blackout, it took about 60 seconds to boil 200ml of water with 2000 watt kettle on the UPS, with decent batteries. 750 watt kettle takes 7 minutes to boil a litre of water from 22°C ambient temperature.
So unless you have, let's say 300AH of Lithium or 100 AH of lead acid batteries, you are stuffed for high speed boiling of water.
Lower load over a longer period will keep your batteries going far longer. The occasional deep stress on lead acid batteries will not cause any long term damage. Just charge them up as soon as possible.

We dont have a kettle as we both dont drink tea or coffee.

We don't have a kettle either, as we live out of a car only, so weight/space options make a caravan look like a piece of cake.
But we can't go without our favourite beans, or tea for that matter. Luckily found our beans in David Jones in Perth to replenish our stocks.
We use a Trangia methylated stove to heat our water. Used to use (still have it) lighter fuel stove which is tiny & brilliant. But for safety decided to go with metho.
We even boil water to add to our venturi air compressor system to have warm showers in the remotest of situations.
One just needs to be creative for life's luxuries anywhere in Australia.
We are not going without any brain dead simple solutions.
Has anyone tried oneof these? I just want some hot water at the sink.
