I got an email flier in from TLC this morning including an Instant Hot water Handwash Tap from Redring @£49.

http://tlc-direct.us8.list-manage.co...e= 55b5bf7be2

Has anyone any experience of these ? Our house is single storey so the gravity feed DHW is at low pressure, compounded by the kitchen mixer tap which I think is designed for mains pressure feed.

There has been several options considered to resolve this but this tap at this price looks a good one, apart from putting a suitable hole through the SS sink.

The questions I'm thinking of are will the flow rate be throttled back significantly to allow the water the heat up, and will the tap cope with filling the washing up bowl with hot water ?

Thanks for any help

I've no experience, but it does look interesting. I notice it mentions
in an offhand way that an electric feed is required, which might be
easier said than done.

It has a 13 amp plug on, so that presumably needs to be cut off if you
are installing it in a bathroom.

Washing hands, yes, but a pretty slow rinse. Filling a bowl?
Eventually, but 2.4kW isn't much.

My immediate thought was that it might be useful in our bathroom, but
never having seen anything like it before, I was wondering which
regulations would cover the wiring. I expect things aren't so strict in
the kitchen, but is there even a precedence for anything like this?
Would you not feel just a tiny bit worried washing your hands under it :-)

Well how else would you heat it. I'd be worried about the long term
reliability of it and also if its well protected from getting too hot.

Well people use those instant heat shower units, so I'd not think it any
worse.
One assumes it would cut out if it shorted to ground.
I'm worried about the lime scale build up on such devices. Surely the way
to use this is as a mains feed tap, anything from cold to hot without a
mixer?

It runs off a 13 amp supply. How long would it take to heat water in your
kettle to fill the washing up bowl? It won't be any quicker.

Fit a pump.

Pretty well all mixer taps seem to be designed for high pressure these
days. So a pump is the only option. I did just this ages ago.

I got a bristan mixer that works at low pressure for our upstairs sink.
The missus is italian, and can't cope with non-mixer taps :-) The
bristan thing works well enough, but I did have to fit a pump to the
bath mixer.

Its designed use is what is suggested by the name,handwashing. A
neater version of the mini instant water heaters often found in
workplaces where hand washing facilities are required such as a small
staff loo or under a pub bar top . Their presence will then satisfy
the health inspector that hot water has been provided but every one
knows that in practice the output is so derisory that busy staff end
removing more dirt from wiping the hands on a ragged towel after
attempting to wash hands under tepid water.
For washing up crocks it will be useless.

One of my more obscure xmas presents to a friend was a water heater for
her stable yard's kitchen. It was when I noticed that many of the more
old fashioned over-sink heaters were nothing more than electric shower
units with a zig-zag spout nailed to the output flange that I realised I
could fit one for 2s6d & a pickled egg - my average xmas pressie spend.

So I sourced a cheapy shower unit and plumbed it up to the otherwise
unused sink hot tap (disabling the ability to turn it off, natch) and,
bingo, hot water for washing both hands and up.

It was a 7/8kW job and it fills a bowl at a modest rate (say 3 mins for
a decent depth) and provides a reasonable stream for doing hands. This
is more than acceptable at a stables. OTOH, the TLC one at a third of
the power and in a domestic setting would be, IMO, absolutely diabolical.

I'd want to see what the flow rate was like (any youtube videos?) the
other instantaneous electric hand washing taps I've used give spray
outlets like a couple of Jif lemons.

Many thanks guys; I should have thought it through logically before posting !! I think Scott M's story about the electric shower conversion says it all.

This is not the answer then to my wife's complaint about the lack of pressure - at my age I have a lack of pressure too, but that's a different matter and not for discussion here.

A pump is probably the solution and perhaps I'll put up a new post about that.

Thanks again

Those somewhat-out-of-fashion waste disposal units mounted below sinks
have a mains supply too. As would a water softener.

2.5Kw - it will be a terribly slow way to fill a bowl and not very hot
either at 50C.

If your HW pressure is low and from a tank, why not add a pump to boost
the pressure?

One reason might be that it might unbalance the HW/CW pressure to your
shower thermostat unit.

It will run at about 1 lpm in the winter and a little bit quicker in the
summer. (assuming a final 40 deg temperature)

You can add a pump to the mixer feed only. Just to overcome the resistance
of a high pressure only tap.

Sadly, low pressure mixers aren't that common these days - and may not be
available in the design you want, look wise.

If you are just looking at improving the kitchen tap hot flow, how about
one of those small unvented water storage heaters? Basically a small
tank with immersion heater near the sink supplying water at mains
pressure. eg:

r/66222

(Note you can get larger ones, but above 15L you need the appropriate
certification to install it)
