As subject, anyone experirence of such things?

Ta.

Daughter had one in a house they rented temporarily and it was forever breaking down with the inevitable long wait to get spares. I cannot remember the make but to me it seemed more trouble than it was worth.

There is a gas pipe nearby. I suppose we could whack a boiler in.
It's for hot water upstairs at work, I was under the impression that the
under sink affairs were quicker and more economical...

We have two of the smallest, cheapest ones from Screwfix:-

https://www.screwfix.com/p/redring-m...5kw-6ltr/5314p

They are pretty easy to install and seem to 'just work', no issues
with them at all and the older one has been in use for more than two
years now.

preesumably you don't live in a hard water area.

We fitted an Elson 10/15L Unvented Water Heater nearly five years ago,
and it has worked perfectly without any maintenance since. However our
water is the softest you can get; I can imagine there'd be problems in a
hard water area.

We run it at a fairly low level, with a timer so that it's only on when
it's likely to be needed, and only heating the water to about 45
degrees.

How much hot water, and *how* hot?

We have a Quooker in our kitchen which heats 7 litres of water under
pressure to over 100 degC and stores it in an insulated container. It
has two outlets - one to a boiling water tap for making tea and coffee
and the other, blended with cold to provide 60 degC or so (adjustable)
to the kitchen tap.

Not cheap, and may be an overkill for what you need.

[Hot water for bathing and showering is heated by a gas boiler and
stored in a vented cylinder in the airing cupboard. But this is a very
long way from the kitchen - resulting in a long wait for the tap to run
hot, and wasting lots of water.]

I installed the Quooker myself several years ago, and we haven't had any
issues with it despite being in a fairly hard water area.

Our water is moderately hard, South Suffolk, the lime scale does tend
to be crumbly though and doesn't seem to build up in heavy deposits.

Just handwashing.

Keep thinking about these for home, for the reasons you mention.

When we moved in nearly 8 years ago there was an Ariston under the sink
in the garage. As soon as I turned it on it tripped the RCD.

I didn't need stored hot water, so had it replaced by an over-the-sink
Triton instant water heater. That worked well off a 13A supply for hand
cleaning after work in the garage, gardening, etc, and I have had
absolutely no problems with it in over 7 years. Do you really need the
store of hot water, or would an instant heater do?

Don't unless you have no other choice. We have them in our village hall.

Tedious to install properly, need a vent to the outside and possibly a
pressure reducer, non-return valve and expansion tank to do it properly.
They cannot supply very much hot water at once. They are just about
acceptable in a seldom used toilet but pretty well useless in a kitchen.

The inline flash boiler ones with a decent power feed are better.

Either sort fail expensively in hard water areas unless you put in a
water softener (more space and plumbing complication) and even then they
seem to have a lifetime of about 5 years before the heating element
insulation fails and they take out the mains RCD when switched on.

The thermal insulation on them isn't great either so they tend to warm
the cupboard and run up the electricity bill if they get left on.
(Not massively but ISTR an average of 50W 24/7 for each one there is.)

They don't all need a vent, the one I recommended (from Screwfix)
doesn't (there is an emergency excess pressure release valve). Nor do
they need any of the other things you suggest unless the water
pressure is over 5 bar (I think that's the limit). The only
requirement is a minumum length of feed pipe with no taps/valves.

If the mains pressure is too high then they work perfectly well with
'tank in the roof space' pressure, that's how I feed both of mine.

The units here are rated for 2.4bar or maybe 3bar. I forget. Local mains
water pressure here is much higher than that.

The catch is that late at night you find water pressure rises a lot when
there is no demand. 5bar isn't the safety margin you might think.

If the mains pressure is too high then they work perfectly well with
'tank in the roof space' pressure, that's how I feed both of mine.

If fed directly off mains water without suitable precautions they are
quite likely to leak drips of water overnight every night.

So do as I did? I suppose not everybody has a tank in the loft now
though.

I installed one of the Ariston units from Screwfix in our memorial hall kitchen about two years ago. It does the job!
If it fails it'll get a like for like replacement. Not worth buggering around with parts and labour by comparison with a new unit price.

The instant ones get shocking reviews until you are up in high KW territory.

The beauty of the storage ones seems to be that the water will be
hotter, quicker, better flow and doable on a 13A.
Just need to consider the inefficiency of the water being kept warm, I
presume they are well insulated.

A mate has put an instant (Triton T30i, 13A) one in his shop,
replacing the storage type that had gone wrong (and was taking up
valuable space) and seems very happy with it? I think part of the
appeal was not only the space saving but the fact they would never run
out of hot water, no matter how often they drew water from it?

He and the other staff are particularly aware of their need for
regular hand washing and having constant hot water seems to be
serviced by said instant heater very well. Also handy for washing up
tea cups and plates and still having hot water straight after for post
customer equipment contact (PC's etc) hand washing.

I was going to fit one here because of the long delay with hot water
coming though from our multipoint water heater but as it's got milder
it's ok to use cold water and soap for the hand washing.

For us it would mean usable hot water for comfortable hand washing in
~6 seconds rather than ~30.

I do get the storage type but concerned how suitable they might be for
regular usage (like wanting to wash your hands after running a bowel
of water for washing up (with the smallest capacity storage units
especially))?

When I was first sorting this place I wanted a source of hot water and
had a 20l Baby Burco (I don't know why). I fitted it with a ball cock
and plumbed it in on a washing machine hose with it stood on the
draining board.

It worked perfectly for a good few months (all be it a bit lossy but I
only put it on when I was round here working).

territory.

It all depends how often you are going to want more than 15L of hot
water - and training users not to turn the tap on for it to run hot.

Instant ones that are any good are 7kW or more flash boilers and not
cheap but they can keep up with demand at peak times.

The beauty of the storage ones seems to be that the water will be
hotter, quicker, better flow and doable on a 13A.

They are not that great on insulation run continuously allow 50W base
load 24/7. The water is still warm the next morning not hot. The problem
we found in the VH was that they were OK in the toilets except when you
had a event with an interval when the first half dozen or so would be
lucky and the rest got to wash their hands in ice cold water.

Likewise in a kitchen except even more so if there is any washing up to
do - you can't have another bowl of hot water for at least 15 minutes.
