'Hot Taps' - running costs?
Discussion
As no one else will know I do underfloor heating in New Zealand - and we have discovered that the single most important factor with running costs is insulation. In our case specifically edge insulation to a concrete slab.
Heating water always takes the same amount of energy, losses are very important. If instant water heaters are indeed 10 watts (an average figure) then it is indeed 3p a day to run. Actually far cheaper than all the losses from a kettle.
Hence from an energy perspective they make good sense.
In our case with the underfloor heating - edge insulation (talking about 30mm of polystyrene), can reduce the running costs by 40%. From 50p per square metre per month down to 30p per square metre per month.
Strangely enough the efficiency of the house itself doesn't seem to matter too much.

we got one of these,
my mother in law got one and i was 100% skeptical,
but after a couple of brews form it, i was hooked.
It boils quickly if you flick the switch by the time you've got mug off the mug tree and chucked a teabag in it, its boiled and its done.
see how you get on with one of these,
we have a hot tap at work, nobody uses it

Thanks - we actually have a big version of this at work. It's great for that but I don't think it's an answer for at home in the kitchen.my mother in law got one and i was 100% skeptical,

Boiling water for cooking, hot water bottles, pots of tea etc. all mean you'd need a kettle as well!

Probably makes economical sense in a busy workplace where people are always boiling too much water and waiting by the kettle.
However you do miss "letching over the HR girls in their yoga pants after they've been for a run at lunch" when pretending to wait for the kettle....
At home its a luxury.

Don't know about the others but it cost me 1.8k for a Quooker Fusion with Scale Control.
Ouch was that for one of the larger capacity versions? I think we paid closer to £900 for a 3 liter version
RRP's here

1.8k for the full system e.g. tank, scale control and the tap itselfI think we paid closer to £900 for a 3 liter version
RRP's here
Also this is for the Fusion system where the one tap does cold, instant hot and instant boiling.
It doesn't make sense, it's madness, it's first world consumerism gone mad, it's just a tap! I could buy a week of cheap hookers and coke for that.

I agree, sod paying that!
But I can get this one through work for £375 with a 2 year parts and labour guarantee.

No it's very expensive BUT I guess it's priorities; I wanted the convenience of instant boiling water (work from home), I wanted instant hot water without waiting for 60 seconds of warm up from the combi and I wanted the whole lot in one integrated tap. At that point your options are limited!Edited by GnuBee on Friday 27th March 10:15
I was looking at the Quooker ones yesterday at the NEC, @ £900 for hot tap, @ £1200 for instant hot water as well, inc VAT and reasonably tasteful mixer tap.
Having seen it in action I was more impressed than I expected. As my kitchen will be some distance from the HW tank and I don't want to wait all day for hot water, and I'm reluctant to have a hot water loop, VAT is reclaimable; it doesn't look too bad.

no secret - this phenomena was discovered i nthe late 1970s / early 1980s with regard to certain types of towerblock construction - hence the dash to clad those which were not being pulled down becasue they had 'concrete cance'r in the exposed floor slabs ...
